A revision of Cladonia stricta

Teuvo Ahti

The arctic lichen Cladonia stricta (Nyl.) Nyl. is divided into three species, viz. C. stricta s. str., C. trassii Ahti, sp. nov.., and C. uliginosa (Ahti) Ahti, comb. nov. Cladonia trassii and C. uliginosa have centrally proliferating scyphi and constantly produce atranorin, while in C. stricta the scyphi are marginally proliferating and atranorin is inconstant. All the three species are essentially arctic to subarctic, circumpolar, but the ranges are poorly known.

Arktiline samblik Cladonia sticta (Nyl.) Nyl. jagatakse siin kolmeks liigiks: C. stricta s. str., C. trassii Ahti sp. nov. ja C. uliginosa (Ahti) Ahti comb. nov. Liikidel C. trassii ja C. uliginosa on keskelt prolifitseeruvad karikad ning nad sisaldavad püsivalt atranoriini; liigi C. stricta karikad prolifitseeruvad servadest ning atranoriin kas esineb või puudub. Kõik kolm liiki on peamiselt arktilise kuni subarktilise (tsirkumboreaalse) levikuga, siiski on nende areaalide ulatust seni vähe uuritud. INTRODUCTION Cladonia stricta (Nyl.) Nyl. was adopted by me (Ahti, 1978) as the correct name for a widespread arctic lichen that was earlier called C. lepidota “Nyl.”, C. gracilescens (Flörke) Vain. or C. cerasphora Vain. The lectotype specimen of C. stricta is from Taimyr Peninsula, Siberia. At the same time I also somewhat provisionally segregated C. stricta var. uliginosa Ahti for a taxon which Vainio (e.g., 1894) had recognized as as a distinct species under the misapplied name C. gracilescens. However, when outlining the distribution of var. uliginosa I noted that the populations of C. stricta in East Asia and western North America are in need of a more through taxonomic analysis. I have later continued the study of C. stricta in these regions. The final impetus for a revision of my concept of C. stricta was provided by Dr Taimi Piin, who pointed me out that the type of C. stricta apparently represents a species distinct from most of the material under this name from Fennoscandia. I had no possibility to make an extensive revision of material in many herbaria, but a new taxonomic scheme of the complex is given below. It still does not include a treatment of all variation noted in Canada and coastal East Asia in this group. Cladonia stricta (Nyl.) Nyl.

Cladonia stricta s. str. is the “apparently new species” mentioned under C. phyllophora Hoffm. by Thomson & Ahti (1994: 146) and in connection with C. alaskana A. Evans by Ahti & Zhurbenko (1994). Perhaps most of the material of C. stricta is found under C. phyllophora in herbaria. It is noteworthy that C. stricta occasionally contains atranorin and such specimens have often been referred to C. stricta while morphologically similar specimens without atranorin have been placed in C. phyllophora. 7 In specimens with well-developed scyphi the numerous perforations of the scyphi constitute a good diagnostic character. del Fuego, Argentina (Stenroos & Ahti, 1991: 324, as C. stricta).

Cladonia trassii is actually a new name for what Vainio (1894, 1922) called C. cerasphora and what has recently been called C. stricta var. stricta (e.g., Ahti, 1977, 1978; Krog et al., 1994), though some material of C. stricta s. str. has been included in the previous descriptions.

Not uncommon in northern boreal forest regions of Fennoscandia but its total distribution is little known. There are few records from North America.

Cladonia uliginosa is characterized by constant occurrence of distinct, centrally proliferating scyphi and numerous podetial squamules. It is very close to C. trassii and I earlier (Ahti, 1978) treated it as a variety (under C. stricta). I have not found distinct intermediates, but further field investigations are required to confirm the differences in relation to C. trassii. The latter species usually has no or no well-developed scyphi. Many of the North European exsiccata distributed as C. gracilescens belong to C. trassii rather than C. uliginosa, which has confused the recognition of these species. ACKNOWLEDGMENTS This contribution is dedicated to Prof. Hans Trass who, among many other things, has studied European and Siberian arctic macrolichens. I am further indebted to Dr Taimi Piin (Tallinn), Dr Mikhail P. Zhurbenko (St. Petersburg), and Ms. Tamara Dudoreva (Kirovsk), Prof. Henry A. Imshaug (East Lansing, MI), who have given me material or observations on C. stricta. Dr George W. Scotter and Prof. John W. Thomson provided me opportunities to study this group in field in Canada and Alaska. The study was financially supported through a grant from the Academy of Finland, and at the last stage through an Andrew W. Mellon Senior Fellowship. REFERENCES Ahti, T. 1977. Cladonia Wigg.

However, some of the species are lichenicolous, several being previously assigned to the genus Leciographa A. Massal. In their world key to lichenicolous fungi, Clauzade et al. (1989) recognized about 20 species of lichenicolous Opegrapha, but since then a further 24 species have been newly described, validated or introduced (or re-introduced) into the genus: O. stereocaulicola Alstrup & D. Hawksw. on Stereocaulon (Alstrup & Hawksworth, 1990), O. physciaria (Nyl.) D. Hawksw. & Coppins on Xanthoria parietina (Atienza, 1992; Coppins et al., 1992); O. sphaerophoricola Isbrand & Alstrup on Sphaerophorus (Isbrand & Alstrup, 1992); O. geographicola (Arnold) Hafellner on Rhizocarpon geographicum, O. rotunda Hafellner on Physconia and O. zwackhii (A. Massal. ex Zwackh) Källsten on Phlyctis argena (Hafellner, 1994); O. brevissima Kalb & Hafellner on Haematomma hilare (Kalb et al., 1995), O. leuckertii S. Kondratyuk & D.J. Galloway on Pseudocyphellaria and Sticta (Kondratyuk & Galloway, 1995), O. physcidiae Kalb & Elix on Physcidia sp. (Kalb & Elix, 1995), O. rouxiana Nav.-Ros. & Hladun on Polyblastia (Navarro-Rosinés & Hladun, 1995), O. cryptotheciae Matzer on Cryptothelia, O. ectolechiaceaum Matzer & R. Sant. on foliicolous Ectolechiaceae, O. epiporina Matzer on Porina, O. kalbii Matzer on Byssoloma, O. mazosiae Matzer on Mazosia, O. phyllobathelii Matzer & R. Sant. on Phyllobathelium, O. phylloporinae Müll. Arg. and O. sipmannii Matzer on Porina epiphylla gr., O. porinicola Matzer on Phyllophiale alba and Porina epiphylla, O. strigula Matzer & R. Sant. and O. uniseptata Matzer on foliicolous Strigula (Matzer, 1996); O. phlyctidicola (Vouaux) Etayo on Phlyctis agelaea (Etayo, 1996); O. encephalographoidea Diederich & Aptroot on Pyrenula, and O. pleactocarpoidea Diederich on Phaeographis (Aptroot et al., 1997). Furthermore, we are aware of several additional, undescribed species, one of which is widely occurring on various species of Heterodermia (Physciaceae). Recent, more critical morphological studies of lichenicolous Opegrapha have shown each species to have a restricted host range, most being either species- or genus-specific, or more rarely family-specific (e.g. O. ectolechiacearum on foliicolous Ectolechiaceae and O. rupestris Pers. on crustose, foveolate Verrucariaceae on limestones), and no species has yet been reliably reported from hosts of different families. No Opegrapha or ‘Leciographa’ has hitherto been reported on Heterodermia, and the fungus on 10 Folia Cryptog. Estonica this genus clearly differs from other Opegrapha species on hosts belonging to the Physciaceae. Accordingly, the collections on Heterodermia are here referred to the species newly described below. Type: [SOUTH AFRICA]: B. G. Hope, on Heterodermia sp., date and collector unmentioned [Herb. Archibald Menzies (1754–1842)] (BM – holotype; E – isotype [South Africa: Cape of Good Hope, on H. speciosa, 1791, A. Menzies]). Opegrapha trassii S. Kondratyuk & Coppins sp. nov. Etymology: Opegrapha trassii is named after the famous Estonian lichenologist Prof. Hans Trass in recognition of his important contribution to our knowledge on the flora of Estonia and other regions of Eurasia, as well as on the family Physciaceae, especially the genus Heterodermia. Fungus lichenicola in thallo specierum Heterodermiae; cortex hospitis brunneolescens. Ascomata lirelliformia, aggregata, simplicia vel interdum breviter furcata, epruinosa, 200– 300(–420) µm longa, 125–160(–200) µm lata, disco rimiformi vel demum hianti. Excipulum integrum, fuscoatrum, admodum K-. Hymenium (40–)45–63.5(–72.5) µm altum, I+ caeruleum. Asci clavati cum annulo apicali amyloideo minuto, (30.5–)32.5–40(–47) × (11–)12–14.5(–16) µm, (2–)4–6(–8)-spori. Ascosporae 3(–4–5)-septatae, hyalinae vel demum granulis brunneascentes, 12.5–17.5(–19) × (3.6–)4.5–5(–5.5) µm. Pycnidia pauca, ±immersa, c. 40–50 µm diam., conidiis bacilliformibus 3.8–5 × 0.5–0.7 µm. Lichenicolous fungus, parasitic on thalli (rarely on thalline margin of host apothecia) on various Heterodermia species. Ascomata arising, ±superficially (i.e. not developing below, and bursting through, the host cortex), in clusters up to 3.5 mm across and containing up to 15(–38) ascomata; surrounding host tissue discoloured brown; clusters characteristically elliptical, with the long axis of the clusters and most individual ascomata parallel with that of the lobes of the host. Individual ascomata Fig. 1 a–b. Opegrapha trassii. a: habitus of ascomata on the host thalli (× 72); b: part of ascomata (× 48). 11 Fig. 2 a–b. Opegrapha trassii. a: asci, b: ascospores. Scale 7 µm. black, epruinose, 200–300(–420) µm long, 125–160(–200) µm wide, and, in sections, (127–)140–150 µm tall; simple or occasionally shortly 1–2-furcate, straight or slightly curved, disc slit-like or eventually gaping. Exciple well developed, entire, 18–27(–32.5) µm wide laterally, (21.5–)30–43(–53) µm wide below, dark brown to blackish brown, sometimes with reddish tinge K- or K+ fuscous brown (loosing red tinge) or slightly olivaceous (never bright green or redbrown). Hymenium hyaline, (40–)45–63.5(–72.5) µm tall, I+ blue, K/I+ blue; epihymenium absent, with the excipulum remaining incurved over the top of the hymenium or becoming evident in widely gaping ascomata and then hyaline to pale brown, 9.0–21.5 µm tall. Hypohymenium dilute brownish, K- or K+ slightly olivaceous, (12.5–)16–23.5 µm tall. Paraphyses branched, 1–1.5(–2) µm wide (in KOH). Asci broadly clavate, (30.5–)32.5–40(–47) × (11–)12–14.5(–16) µm, with K/I+ blue ring around the top of the ocular chamber, (2–)4–6(–8)-spored. Ascospores hyaline, 3(–4–5)septate, upper 2 (3 or 4) cells somewhat more swollen than the lower cells, 12.5–17.5(–19) × (3.6–)4.5–5(–5.5) µm, apices obtuse, sometimes with a thin perispore <1 µm thick; old spores released from asci sometimes pale brown due the external deposition of minute brown granules. Pycnidia sometimes present around the outside of the ascomatal clusters, immersed in the host tissue, dark brown to black, c. 40–60 µm diam.; wall tissue dark brown, K-; conidia (microconidia) bacilliform, 3.8–5 × 0.5–0.7 µm (Fig. 1, 2). Opegrapha trassii is very variable with respect to the numbers of spores in the ascus; this can be 2, 4, 6 or 8, and all four types have been seen in sections of a single ascoma. However, asci with 4 or 6 spores are those most commonly encountered. Only two species of Opegrapha have been previously described from hosts in the Physciaceae, and both differ from O. trassii in having rounded ascomata and larger ascospores: O. rinodinae Vêzda on Phaeorrhiza nimbosa (ascospores 22– 26 × 4–6 µm) and O. rotunda Hafellner on Physconia (ascospores 18–22 × 5–6 µm) (Hafellner, 1994). Despite its specific epithet, O. physciaria (Nyl.) D. Hawksw. & Coppins grows on Xanthoria parietina (Teloschistaceae) and has 8-spored asci that lack an apical K/I+ blue ring. Two collections in E have an unidentified Opegrapha on Pyxine cocoes (Physciaceae) from Botswana 12 Folia Cryptog. Estonica Fig. 3 Distribution of Opegrapha trassii. (Long 12449, Long & Rae 881). They differ from O. trassii in that the clusters of ascomata arise below and eventually burst through the cortex of the host, the asci are 8-spored, and the ascospores are somewhat broader, with many reaching a width of 5.5–6 µm. What seems to be an additional Opegrapha species on Heterodermia, has recently been found. A small specimen, collected in Papua New Guinea and sent to the first author by Dr P. Diederich, differs from O. trassii in having more robust ascomata with a soon expanding disc, to 460 µm wide. In sections the ascomata are much taller (to 280 µm) with a taller hymenium (80–85 µm) and much taller combined hypothecium and lower exciple (to 200 µm; mostly less than 60 µm in O. trassii). The asci are 4-spored, but the ascospores are consistently 5-septate at maturity (no mature 3-septate ascospores being detected), and longer (17.5–21.5 × 4.5–6,5 µm). It seems unlikely that this collection (Diederich 10317) represents an extreme morphotype of O. trassii, and further collections will surely prove it to be a distinct species.

Eestist on teada 12 samblikuliiki, mis kuuluvad Lecanora subfusca rühma, neist 10 on kindlasti esindatud Eesti kaasaegses flooras, üks liik on tõenäoliselt hävinud ja üks – kaheldav. Lecanora circumborealis on uus liik Eesti lihhenoflooras; neli liiki on väga haruldased (L. caesiosora, L. epibryon, L. glabrata, L. impudens) ja seitse liiki on üsna või väga tavalised Eestis. Käesolevas töös on esitatud nende liikide määramistabel ja üldine levik Eestis. Tutvustatud on ka liikide määramiseks vajalikke anatoomilisi tunnuseid. INTRODUCTION The name “Lecanora subfusca” has been used by many authors as a collective name for a group of epiphytic and epilithic species, many of which are widely distributed in the Northern Hemisphere. The combination Lecanora subfusca (L.) Ach. was proposed by Acharius in 1810, who divided the species into eight varieties, seven of which were later raised to the specific level. Today the name L. subfusca is out of use according to the proposal of Vitikainen & Brodo (1985) to include it in the list of rejected names. The characteristic features of this group are: * ellipsoid to broadly ellipsoid ascospores (approximately 10–20 × 6–9 mm), * apothecial discs are generally reddish brown, * apothecial margin (amphithecium) contains calcium oxalate crystals, * thallus and apothecial margin react K + yellow (atranorin), * thallus is crustose, ± grey (Brodo, 1984; Eigler, 1969). The aim of this study was to revise the L. subfusca group in Estonia. A list of species, data on their distribution and some ecological notes are presented. This study is part of a larger project to compile a new checklist of Estonian lichens. As morphological features in the L. subfusca group are very variable and overlapping, it is necessary to study apothecial anatomy while identifying the species. Therefore some aspects of apothecial anatomy (epihymenium and amphithecium types) in this group are briefly discussed following Brodo (1984). MATERIALS AND METHODS The study was based on collections in the herbarium materials of the Institute of Botany and Ecology at the University of Tartu (TU); the specimens collected in Estonia and kept in the Universities of Helsinki (H) and Riga (RIG) were also considered. Altogether about 1100 specimens were studied. Additional material for comparison was received from Helsinki (H). Besides the herbarium materials, publications by Bruttan (1870), Mereschkowski (1913), Räsänen (1931), Trass (1967, 1970) were taken into account when composing the list of species. Cross-sections of apothecia were made by hand and examined by light microscope (MBI - 3). Spot tests were made with 10 % potassium hydroxide (K) and paraphenylenediamine in ethanol (Pd); K and 50 % nitric acid (HNO3) were used to determine the solubility of epihymenial granules, HNO3 was used also for hymenial colour tests. The secondary substances were identified using thin-layer chromatography (TLC) described by Culberson & Kristinsson (1970) and Culberson (1972) only in a few occasions – when inevitable for the identification of species (in 31 specimens). 16 Folia Cryptog. Estonica The herbarium data were sorted using the computer program BRAHMS and the program DMAP was used to compose the distribution map in Estonia. The figures 1 and 2 (from Brodo, 1988, drawn by Susan Laurie-Bourque) are reproduced with permission from the Canadian Museum of Nature, Ottawa, Canada. The following key books and papers were used to identify the specimens and to compose the key: Brodo (1984), Brodo & Vitikainen (1984), Brodo et al. (1994), Foucard (1990), Poelt & Vêzda (1981), Purvis et al. (1992), Tønsberg (1992), Wirth (1995). RESULTS AND DISCUSSION Important apothecial characters in the Lecanora subfusca group The anatomy of the L. subfusca group has been studied in detail by different authors (Brodo, 1984; Eigler, 1969; Magnusson, 1932; Poelt, 1952). Several types of apothecia have been described according to the structure of the epihymenium and amphithecium. Hereafter only some of those epihymenium types – occuring in Estonian species - will be discussed. The epihymenium is the upper layer of the hymenium that is differentiated by pigmentation (within or between the tips of the paraphyses) and granulation (above or between the tips of the paraphyses) (Brodo, 1984). Epihymenium types (according to Brodo, 1984): 1. chlarotera-type – epihymenium coarsely granular, granules are on the surface of the hymenium, soluble in KOH and HNO3; not pigmented or pigmented reddish brown to olivaceous brown (pigmentation disappears in KOH, in dark apothecia epihymenium HNO3 + reddish) (Fig. 1); 2. pulicaris-type – epihymenium finely granular (granules are much smaller than in chlarotera-type epihymenium), located on the surface of the hymenium and between the tips of paraphyses (up to 20 mm in depth), soluble in KOH but insoluble in HNO 3 ; pigmented brown to olivaceous brown (pigmentation disappears in KOH, in dark apothecia epihymenium HNO3 + reddish) (Fig. 1); Fig. 1. Epihymenial granules: (a) chloroteratype, (b) pulicaris-type in L. hybocarpa. Scale: each unit = 10 µm. 3. glabrata-type – epihymenium not granular or inspersed, pigmented clear reddish brown (pigmentation persists in KOH). The amphithecium has been considered to be all those tissues external to the hypothecium and hymenium, and includes also the cortex (Brodo, 1984). Three amphithecium types can be distinguished in the group (according to Brodo, 1984): 1. pulicaris-type – very large, irregular crystals in clumps in amphithecial medulla (Fig. 2); 2. campestris-type – small, irregular crystals entirely or partially filling amphithecial medulla, not entering the cortex; 3. allophana-type – small, irregular crystals extending from the medulla into the cortex (Fig. 2). In some cases the amphithecial crystals may be rather few or even absent, but generally they are abundant. The pulicaris-type is usually easily recognized while the differences between the campestris- and allophana-types are less obvious. Combining the epihymenium and amphithecium types, the species can be divided into groups (Table 1). 17 Fig. 2.

Only those synonyms in the Lecanora subfusca group are listed that are mentioned in the checklist of Estonian lichens by Trass (1970). LECANORA ALLOPHANA Nyl. – very widely spread all over the country (more than 200 localities), common in parks in the countryside and also in towns. On deciduous trees (Acer, Fraxinus, Populus, Tilia), rarely on wood. L. ALLOPHANA f. SOREDIATA Nyl. – rare in Estonia, four specimens from the western, northern and southern parts of Estonia, on Populus tremula (TLC: atranorin, terpenoids). L. ARGENTATA (Ach.) Malme (syn. L. subfuscata H. Magn., L. subrugosa Nyl.) – very common in wooded meadows and deciduous forests in western regions, frequent also in other parts of Estonia. On deciduous trees (Acer, Fraxinus, Populus, Quercus, Sorbus, Tilia), rarely on wood. L. CAESIOSORA Poelt – very rare, only one locality in western Estonia: Hiiumaa Co., Saarnaki Is., on stone fence, 16 Aug. 1974, leg. E. Sander, det. I. Brodo (TLC 1120-16 by Brodo 1993: atranorin, chloroatranorin, roccellic acid) (TU) (Jüriado, 1997). L. CAMPESTRIS (Schaer.) Hue – quite frequent in western and northern Estonia, only one specimen has been collected at an inland location (from southern Estonia). On calcareous and siliceous rocks, also on manmade substrata. 18 Folia Cryptog. Estonica L. CENISIA Ach. [syn. L. atrynea (Ach.) Nyl.] – quite common on the coast and islands in western and northern Estonia, sparse inland. On siliceous rocks, sometimes also on wood. L. CHLAROTERA Nyl. – very common all over the country (more than 100 localities), in forests and parks in the countryside and in towns. On deciduous trees, also on wood (14 specimens have been studied by TLC: atranorin, gangaleoidin, ± norgangaleoidin, ± roccellic acid). L. CIRCUMBOREALIS Brodo & Vitik. – new for Estonia, rare – five localities distributed in different parts of Estonia (Fig. 3). Specimens examined. 1. Harjumaa Co., near Vasalemma, on Betula pubescens, 15 June 1947, leg. E. Parmasto, verified by O. Vitikainen (TLC: atranorin, roccellic acid) (TU). 2. Harjumaa Co., near Maardu, on Betula sp, 23 May 1942, leg. J. Seim (TLC: atranorin) (TU). 3. Läänemaa Co., Vormsi Is., Diby, on wood, July 1987, leg. R. Allmäe (TLC: atranorin) (TU). 4. Valgamaa Co., Kääriku, on Betula pendula, 27 March 1966, leg. H. Trass (TLC: atranorin, roccellic acid) (TU). 5. Viljandimaa Co., Vihi, on wood, 30 July 1996, leg. I. Jüriado (TLC: atranorin) (TU). available and, therefore, it is not possible to verify the taxon. According to the literature (Santesson, 1993), the species occurs mainly on Fagus, which does not occur in Estonia. Today we still include the species in the checklist of Estonian lichens but consider it doubtful. L. IMPUDENS Degel. – very rare, two localities only: Saaremaa Co., Kuressaare, on Fraxinus excelsior, 28 June 1980, leg. & det. T. Rand-lane, verified by G. Thor 1991 (TLC: atranorin) (TU) (Randlane, 1986); Tartumaa Co., Luunja, in humid forest on Tilia cordata, 1 Jan. 1949, leg. H. Trass (TLC: atranorin) (TU). L. PULICARIS (Pers.) Ach. [syn. L. chlarona (Ach.) Nyl., L. coilocarpa (Ach.) Nyl., L. pinastri (Schaer.) H. Magn.] – widespread in all parts of Estonia (more than 200 localities). On coniferous trees (very often on Pinus sylvestris), frequently on wood, on deciduous trees (Alnus incana, Betula, etc.). L. RUGOSELLA Zahlbr. – very common all over the country (more than 100 localities), in forests and parks, in the countryside and in towns. On deciduous trees, also on wood. Comments on the species’ list of the Lecanora subfusca group in Estonia Fig. 3. Distribution of Lecanora circumborealis in Estonia. *L. (Ach.) Ach. – very rare, only one locality from the last century: Saaremaa Co., Muhu Is. (Moon) (TU), “an der Erde über Mossen” (Bruttan, 1870). ?L. GLABRATA (Ach.) Malme – very rare, one locality; mentioned by Mereschkowski (1913) (Harjumaa Co., Tallinn), the specimen is not EPIBRYON Lecanora circumborealis is morphologically and anatomically very close to L. pulicaris and therefore, it is necessary to use the complex of characteristics to distinguish the two taxa (p. 19); for more information see Brodo (1984) and Brodo & Vitikainen (1984). L. impudens is morphologically rather similar to L. allophana f. sorediata but, according to Tønsberg (1992), their terpenoid patterns differ. TLC was carried out on four local specimens and showed that two specimens of L. im-pudens contained only atranorin, while two specimens of L. allophana f. sorediata contained some terpenoids in addition to atranorin. Lecanora rugosella has been treated as a form or synonym of L. chlarotera (Clauzade & Roux, 1985; Poelt, 1952; Wirth, 1995) or also as a distinctive species (Brodo, 1984; Purvis et al. 1992; Santesson, 1993; Vitikainen et al. 1997). They both have the same epihymenium and amphithecium types (Table 1), and other 19 anatomical and chemical features are also similar. These species have been separated according to their morphology: L. rugosella has coarsely verrucose thallus and more thicker and verrucose apothecial margin than L. chlarotera. In Estonian herbarium material some specimens of L. chlarotera are slightly sorediose, and there are quite a number of specimens with soralia-like heaps among both L. chlarotera and L. rugosella. Further investigation of those species is needed. Those specimens, which earlier were determined as L. subrugosa, are now considered extreme morphological variants of L. argentata caused by the substrate; no anatomical differences between those species could be observed, futhermore, morphological intermediates exist (Lumbsch & Feige, 1996). Morphological intermediate specimens are also present among Estonian herbarium materials, and the distinguishing between these two species was often impossible.

New combinations under Heterodermia are proposed for 12 species. Kokkuvõte: S. Kurokawa. Heterodermia (Physciaceae) kataloog. Loetletud on kõik perekonna Heterodermia praegu teada olevad liigid viidetega prioriteetsetele kombinatsioonidele. Uute kombinatsioonidena esitatakse 12 Heterodermia liiki. INTRODUCTION ENUMERATION OF TAXA Since the genus Heterodermia Trevis. was resurrected by Poelt (1965), various authors have proposed new combinations under the genus. They are Culberson (1966), Skorepa (1972), Follmann & Rédon (1972), Awasthi (1973), Follmann (1974, 1983), K. P. Singh & S. R. Singh (1976), Swinscow & Krog (1976), Hale (Vêzda, 1976), Dey (1976), Wetmore (1976), K. P. Singh (1979), A. Singh (1980), Weber (1981), Hawksworth (Shaw, 1984), Elix (1985), Wei & Jiang (1986), Weber (Egan, 1987), Wei (1991) and Trass (1992). However, there are some confusions in author citation. For instance, the combination Heterodermia boryi was proposed by three different authors in 1976. Although H. boryi (Fée) Kr. P. Singh & S. R. Singh is earliest as shown below and keeps the priority, H. boryi (Fée) Hale was employed by Park (1990). Even though Trevisan (1861) did not propose such a combination, Aptroot (1987) used Heterodermia galactophylla (Tuck.) Trevis. In the present paper, all taxa now considered to belong to Heterodermia will be listed, with special reference to the priority of combination under the genus. A number of new species of the genus described by various authors in recent years are also included. In addition, new combinations under Heterodermia are proposed for 12 species, which have not yet been transferred to the genus. HETERODERMIA ALBICANS (Pers.)

Ingvar Kärnefelt The Botanical Museum, Lund University, Östra Vallgatan 18, S-223 61 Lund, Sweden Abstract: 25 lobate and subfruticose species of Caloplaca occurring mainly on coastal rocks are discussed. This special group of lichens is relatively well-known from western Europe and North America. However, for other parts of the world with suitable environmental conditions such as in Australia, southern Africa and South America, there are still large gaps of information on this basically ecologically delimited group of lichens. Kokkuvõte: E. I. Kärnefelt. Mariinsete hõlmiste ja poolpõõsasjate kuldsamblike (Caloplaca) liikidega seotud probleemid. Käsitletakse 25 hõlmadega või poolpõõsasja tallusega kuldsambliku (Caloplaca) liiki, mis levivad peamiselt rannakaljudel. Need samblikud on Lääne-Euroopas ja Põhja-Ameerikas üsna hästi uuritud. Teistest piirkondadest – Austraaliast, Lõuna-Aafrikast ja Lõuna-Ameerikast – on selle ökoloogiliselt hästi piiritletud samblike rühma kohta veel vähe teada. INTRODUCTION The supergenus Caloplaca (Fr.) Th. Fr. comprises a large diversity of presumably near 1100 species, and can partly be divided in more or less distinctive species groups (Kärnefelt, 1989; Poelt & Hinteregger, 1993; Wetmore & Kärnefelt, 1998). It is under discussion whether some of these groups could represent genera or not (Kärnefelt, 1989; Poelt & Pelleter, 1984). This is also a matter of principles and different generic concepts (Kärnefelt, 1991; Nimis, 1997). Here, I guess we will always have to deal with personal views related to what value one could assign to important characters, in addition to general knowledge of the diversity and variation in a certain group. In the relatively new Estonian macrolichen flora by Trass & Randlane (1994) several placodioid groups were included. One of these groups was Caloplaca sect. Gasparrinia comprising 11 species, of which C. marina, C. microthallina, C. scopularis, C. thallincola and C. verruculifera were treated, all well-known from western Europe occurring in the spray zone on coastal rocks (Nordin, 1972; Purvis et al., 1992). Coastal rocks in mainly temperate and subtropical regions are fairly richly colonized by lichens of the Teloschistaceae, particularly of the genus Caloplaca but also Teloschistes and Xanthoria. Presumably the combination of several factors, involving nutrient rich sites, exposure and competition, have made this group of lichens successful in coastal situations throughout the world. Is Caloplaca section Gasparrinia worth being recognized taxonomically at generic level, or is it just one of these names which has been mentioned in floras from time to time? An answer like ”usually the Gasparriniae can be easily recognized” shows some weak points. Seen from the character (1) ”lobed or with distinctive marginal lobes”, there are species which will be difficult to place within a possible genus. The other important characters defining a possible genus Gasparrinia are (2) ”anthraquinone pigmented lobes” and (3) ”cortical layers with more or less distinctive paraplectenchymatous hyphae” (Wetmore & Kärnefelt, 1998). However, there are species within the grey or black species group which are both lobed and lack anthraquinones. Most of the yellow and lobed species have distinctive paraplectenchymatous cortical layers, but there are also species in this group with different cortical structures. The aim of this paper, in connection with other projects in the genus Caloplaca (Wetmore & Kärnefelt, 1998), is the present an overview, worldwide, of these species. 28 Folia Cryptog. Estonica DISCUSSION The lobate species of Caloplaca occurring on coastal rocks have been fairly well investigated in western Europe (James, 1962; Nordin, 1972; Purvis et al., 1992) and recently also in North America (Arup, 1995b). In other parts of the World, however, the knowledge of this group is much less well documented. The most spectacular maritime belt dominated by Teloschistaceae is generally found on the western parts of the continents, mainly in temperate but also in subtropical regions, where the species encounter the large ocean waters.

BRATTEI The Arctic and adjacent regions Coastal rocks, particularily in the arctic and adjacent regions, are rarely colonized by a rich lichen cover. This is probably associated to the harsh environmental conditions during the long winter season. In King Karls Land in eastern Svalbard, where I spent the summer of 1980, I did not observe any marine Teloschistaceae at all, apart from scattered Xanthoria elegans . Extensive field work has been carried out especially in Greenland within the Arctic region. However, Hansen et al. (1987) only recorded C. scopularis and C. verruculifera from coastal rocks. Western Europe The most frequent species along the sea coast in western Europe is probably C. marina, an exclusively littoral species, well adapted to its habitat and with rather limited morphological variation. Caloplaca marina varies, however, in the development of the marginal lobes and it has been discussed whether it should be treated among the lobate species or not (Arup, 1992; Wetmore & Kärnefelt, 1998). Caloplaca littorea, known from the British Isles and the southern part of the European coast line, characterized by small isidia and with less well developed marginal lobes, is presumably closely related with C. marina (Kärnefelt, 1990b; Purvis et al., 1992). Nordin (1972) treated C. microthallina in the Gasparrinae. This species, characterized by a rather small thallus composed of squamulose lobules, is probably more closely related to the C. squamosa group (Wetmore & Kärnefelt, 1998). Three other species with marginal lobes are rather widespread along the European sea coast, i.e. C. scopularis, C. thallincola and C. verruculifera. Caloplaca scopularis is the smallest of these species, characterized by lobes with normal paraplectenchymatous layers and polarilocular spores. Caloplaca thallincola is usually much larger, with distinctly effigurated lobes. The citriform shape of the ascospores, however, suggests that this species is more closely related to two mainly inland species, C. aurantia and C. flavescens. Caloplaca verruculifera is unique in having verruciform or globular isidia covering the lobes (Kärnefelt, 1990b). The cortex also differs in the presence of more conglutinated or prosoplectenchymatous hyphae. Presumably, C. verruculifera is most closely related to C. granulosa, which can also occur at much higher altitudes (Nimis, 1993; Poelt & Romauch, 1977). Seen particularly on the cortical structure and general habitat ecology C. verruculifera could also 29 show affinities with C. gomerana from the Mediterranean region, and furthermore with C. lucens and C. orthoclada from South America. The Mediterranean region and northern Africa This region seems in general to be poor in lobate species occurring on coastal rocks. In the first place this might be related to the warmer climatic conditions and to warmer water. Among the species discussed so far, C. thallincola occurs extremely rarely from coastal rocks in the Mediterranean region (Nimis & Poelt, 1987; Nimis, 1993). This beautiful species is otherwise more widespread in the southern parts of western Europe and in the British Isles, where it prefers calcareous rocks. The most closely related species, C. aurantia and C. flavescens, are both relatively widespread in the Mediterranean region also in coastal situations (Clauzade & Roux, 1985; Ozenda & Clauzade, 1970). Among the species known from coastal rocks in the Mediterranean region there are entities within the C. marina group, which, as mentioned before, not really belong to the lobate species. Caloplaca ora was separated from C. marina on the generally smaller thallus with thinner lobes, spores, and paraphyses (Nimis & Poelt, 1987). It is obviously widespread in the Mediterranean region. Caloplaca littorea was listed by Nimis from Sardinia, where it is, however, very rare (1993). Another beautiful species, C. gomerana or until recently referred to as C. gloriae, known from the eastern Iberian Peninsula and from north-western Africa and Macaronesia (Hafellner, 1995), is not a strictly littoral species, occurring mainly near the coast up to 250 m altitudes. Caloplaca gomerana is unique in its laminal pseudocyphellae and a special type of cortical layers (Llimona & Werner, 1975). Similar pseudocyphellae are occasionally developed in C. verruculifera, to which this species is probably related (Arup, 1994). Eastern North America The marine species of Caloplaca occurring on sea shore rocks in North America were treated by Arup (1995b). Five species, of which at least two have distinct marginal lobes, i.e. C. scopularis and C. verruculifera were recorded for eastern North America (Arup, 1994). Many plant groups, and biota in general, distributed in western Europe, occur in corresponding habitats in eastern North America, which is linked both by pre-Pleistocene history and reinvasion of biota after Pleistocene glaciations (Hultén, 1963; Kärnefelt, 1979). Of the two species mentioned, however, C. verruculifera also occurs on the North American west coast. Arup (1994) also treated the squamulose C. microthallina from both the eastern and western coasts. Western North America Arup (1992, 1995a) treated several different species of Caloplaca occurring on coastal rocks in western North America. Among these, however, only three belong to the lobate group. One of them is C. brattiae, a strictly littoral species occurring in the lowest belt along the Californian coast line (Arup, 1995a). It is presumably closest to C. scopularis. These two species actually behave as vicarious taxa, having only minor differences in spore size, quantity of apothecia and structure of lobe tips. Caloplaca scopularis only occurs on sea shore rocks on the north American east coast and C. brattiae on the west coast. Caloplaca brattiae differs from C. verruculifera, which occurs further north, in the structure of the cortical layer. Two other species, C. ignea and C. impolita, confined to the coast line, have distinctive marginal lobes (Arup, 1995a). Caloplaca ignea, characterized by bright orange to reddish lobes and the central portions covered with apothecia, is not a strictly littoral species and may occur as high up as to 500 m. This species is probably most closely related the C. saxicola group. Caloplaca impolita, which has much broader and flatter marginal lobes, may also occur at slightly higher altitudes and not only on the shore. Both species are mainly distributed along the southwestern coast from central California to Baja California (Arup, 1995a; Wetmore & Kärnefelt, 1998). Arup (1992) also reported C. marina from the North American west coast. Caloplaca rosei, which occurs within the same range as C. marina, has less well developed marginal lobes and a more continuously areolated thallus. 30 Folia Cryptog. Estonica The most unusual species occurring on coastal rocks in western North America, however, is C. coralloides (Arup, 1995a; Poelt & Pelleter, 1984; Wetmore & Kärnefelt, 1998). This is a strictly littoral species, known from Oregon to Baja California and characterized mainly by a subfruticose thallus consisting of yellowish coralloid lobes (Poelt & Pelleter, 1984). A slightly different species, C. thamnodes, with broader and more dark orange, coralloid lobes and scattered pseudocyphellae, occurs further south in the northern coast of Baja California, where both species may occur in the same habitat on rather exposed coastal rocks. Otherwise these species do not differ much in anatomical features, both being characterized by rather massive prosoplectenchymatous cortical layers and by the typical subfruticose shape of the thallus. It is remarkable that a similar pair of species, C. bonae-spei and C. eudoxa, has developed under similar environmental conditions along the Atlantic coast in Southern Africa (Kärnefelt, 1991). Eastern Asia The lichen flora in the eastern asiatic region has not been well investigated, perhaps with the exception of Japan. There are also relatively few duplicate collections of maritime species of Caloplaca distributed in European and North American herbaria. There seem to be rather few lobate marine species in Caloplaca from this region. Caloplaca scopularis seems to be one of the most common species, at least reported from Japan (Yoshimura, 1987). This species dominates the coastal rocks I studied in Petrov Island in Primorye, Russia in 1991. Presumably, C. brattiae could also occur in this region, which is much more probable than the occurrence of C. scopularis judging from their biogeographical patterns. There are many examples of Amphi-Beringian plants which have wide distributions in western North America, over the Aleutains, down to Kamtchatka and the Far East region (Kärnefelt, 1979). Caloplaca scopularis does not match this pattern at all, belonging to an eastern North American and Amphi-Atlantic element. Caloplaca marina probably occurs rarely in the far eastern region seen from my own collections from Japan and Primorye. Australasia and New Zealand There are several, strictly littoral species of Caloplaca in Australia. Some of them are still undescribed and the whole genus is currently being treated for the Flora of Australia project. Among the littoral species, however, only a few have marginal lobes, the most conspicuous being C. sublobulata. This species, which originally was described from southernmost South America, has been slightly misunderstood due to its broad morphological variation (Kärnefelt, 1988; Santesson, 1944). During my fieldwork in Australia in October–November 1997, I observed large populations of C. sublobulata both from coastal rocks in Western Australia and from Victoria in southeasternmost Australia (Fig. 1). I have seen material of this distinctive species also from New Zealand. Among the other littoral species, I also recorded a few small populations of C. marina on coastal rocks in Victoria. Caloplaca cribrosa occasionally occurs on coastal rocks in Tasmania and New Zealand (Poelt & Pelleter, 1984). This species is characterized by rather coarse lobes with distinct pseudocyphellae which occasionally are also slightly raised like in the other subfruticose species (Fig. 2). It is strange that this species does not seem to occur on the Australian mainland such as in the SW region or along the southern coast. Furthermore, Caloplaca cribrosa does not form a biogeographical pair similar with the related species occurring in SW North America and in SW Africa. Caloplaca cribrosa is more likely to be associated with C. regalis in the Western Hemisphere. The anatomical characters in the cortical layers are otherwise the same in this species and in the American and African ones known (Fig. 3). Africa Apart from various local floristic works, Africa is still a lichenologically very much underinvesitgated continent. I have seen almost no records of littoral species of Caloplaca from the large tropical regions north of the southern African states. In South Africa C. sublobulata has been recorded from coastal rocks along with a closely related isidiate species C. isidiosa (Kärnefelt, 1990a, b). Caloplaca marina also occurs scattered in the same region. 31 Fig. 1. Caloplaca sublobulata . a.

If any, this group of seven species, characterized by a combination of anatomical and morphological characters and habitat selection, should be separated at generic level (Figs 2, 3). The Antarctica and adjacent regions Fig. 3. Caloplaca cribrosa. a. Cross section, b. longitudinal section (MEL 1000439) (drawing by Rex Filson). Two of the unique subfruticose species occur within the western part of southern Africa on coastal rocks, C. bonae-spei from the southernmost part, and the closely related C. eudoxa further north from central Namibia to southern Angola (Kärnefelt, 1991; Poelt & Pelleter, 1984). Caloplaca bonae-spei is a strictly littoral species, often occurring within populations of C. isidiosa and C. sublobulata, while C. eudoxa can occur also in the inland. Much further north in Mauritania, a third species C. mauritanica has been recognized within this remarkable group of lichens. I have not seen any material from the only known locality, situated more inland and not really littoral. But I would guess that C. mauritanica is extremely close to, or even identical with, C. eudoxa. The whole subfruticose group preferably seems to be littoral in its ecological Søchting & Øvstedal (1991) made a survey of the genus in the Western Antarctic region. In spite of the limited open land available and of the many scientific expeditions, the lichen flora of this region is still very poorly known. Fourteen Caloplaca species were recorded altogether, but only a few of them develop distinctive marginal lobes and occur on coastal rocks, i.e. C. isidioclada, C. lucens, C. sublobulata and C. regalis. Of these species C. isidioclada, C. lucens and C. sublobulata have all more or less distinctive marginal lobes, while C. regalis belongs to the group of subfruticose species. Caloplaca isidioclada is mainly characterized by lobes partly being covered by finger-like to coralloid isidia and cortical layers composed of paraplectenchymatous cells (Søchting & Øvstedal, 1992). Its relation to C. isidiosa (Vain.) Zahlbr. is unclear, and type material has to be examined. The identity of C. lucens is still somewhat unclear. The material referred to by Søchting & Øvstedal (1992) is saxicolous, while the type from Kerguelen Island was based on lignicolous material (Santesson, 1944). This species, furthermore, is probably not very closely related to the other marginally lobed species, apart from C. gomerana, C. verruculifera and the inland species C. trachyphylla (Hansen et al., 1987; Wetmore & Kärnefelt, 1998). Caloplaca lucens and the other species have more or less rough convex lobes with isidia or papillae, tiny or distinct pseudocypheallae and prosoplectenchymatous cortical layers. Caloplaca regalis belongs to the group of subfruticose taxa (Poelt & Pelleter, 1984). It differs slightly from the pairs C. bonae-spei/C. eudoxa and C. coralloides/C. thamnodes in the presence of more horizontally directed marginal lobes and thin paraplectenchymatous external cortical layers. Furthermore C. regalis does not seem to be strictly littoral, but it is more general coastal, occurring higher up to several hundred meters above sea level. Caloplaca ambitiosa, 34 Folia Cryptog. Estonica which was described from the subantarctic islands, has shown to fall within the variation of C. regalis (Søchting & Øvstedal, 1992). South America South America is a large continent with a very long coastal line and, similarily to Africa and Australia, with a relatively little known lichen flora. Apart from a few special treatments, e.g. by Malme (1926) on the Teloschistaceae, only larger coastal species of Caloplaca have been mentioned (Grassi, 1952; Santesson, 1944). Among the species already discussed C. isidiosa is known from scattered localities in Brasil and in the Galapagos Islands (Kärnefelt, 1988, 1990a, b). Other littoral lobate species known are C. sublobulata, mainly from southernmost South America (Kärnefelt, 1988; Santesson, 1944). From Chile I have seen material of a species named C. orthoclada, which in some ways reminds of C. lucens with distinctly effigurated marginal lobes. The surface of the lobes, however, is not rough as in C. lucens, but the cortical layer composed of prosoplectenchymatous layers is, of the same structure. Type materials must be more carefully examined in these taxa in order to settle possible affinities. Among the subfruticose species, C. regalis is known from coastal situations in southernmost South America including the Falkland Islands. Further north along the Chilean coast near Valparaiso, another species, C. fragillima, has been recognized, growing on coastal rocks (Poelt & Pelleter, 1984). Caloplaca fragillima, known only from the type locality, is presumably very closely related to C. coralloides or even identical with this species. Much more field work should be carried out along the great Pacific coastline, and also along the Atlantic coast in South America which probably will reveal very interesting material for phytogeographical discussions and theories on evolution and affinities especially among Southern Hemisphere entities.

The data obtained in these years show constant deterioration of air quality in Viljandi. Basing on the results of 1997, we distinguished four lichen zones: I, the zone of lichens tolerant to strong acidic air pollution (acidification of the substrate); II, the zone of lichens tolerant to moderate acidic air pollution; III, the zone of lichens tolerant to alkaline dust pollution (eutrophication of the substrate) and IV, the zone of lichens sensitive to acidic air pollution.

INTRODUCTION In recent years relatively numerous investigations into the accumulation of elements in lichens as a characteristic of air quality have been conducted. However, beside this method of the bioindicational assessment of air quality, also the classical method of mapping of the distribution of indicator species is used, often combined with the index method (Wirth, 1987; Hosiaisluoma, 1994; Hobohm, 1994; Kirschbaum, 1995; van Dobben, 1996; Liiv & Sander, 1996). The method of mapping of the distribution of indicator lichens serves as the quickest and simplest way for establishing the problematic areas of air pollution, but also for fixing the improvement in air quality in some region on the basis of the distribution of indicator species (Hobohm, 1994; van Dobben, 1996; Ammann, 1997). In Estonia, the use of lichens as bioindicators for the assessment of air quality was initiated in the late 60s at the then Tartu State University with the study of lichen groupings growing on trees in the town of Tartu (Trass, 1968 a, b). In Viljandi, irregular assessments of air quality have been performed since 1972, using different methods of lichen analysis. In this year field works were started to collect material for a graduation thesis under the supervision of Prof. Hans Trass (Liiv, 1973). Lichen studies were repeated in Viljandi in 1976 and 1983 (Liiv, 1978, 1987, 1989 a, b; Eensaar, Liiv, 1983). Analyses of epiphytic lichen groupings in Viljandi were carried out also in 1987 and 1991. These were mostly aimed at solving the methodical problems of using lichens as bioindicators. The present paper gives a brief comparison of the results of the lichen analyses performed in Viljandi in these years with the data we obtained during mapping of indicator lichens in 1997. MATERIAL AND METHODS Viljandi is a small town (22 000 inhabitants) in Southern Estonia (Fig. 1). Viljandi is a holiday town by the picturesque Lake Viljandi with Castle Park and old wooden houses. As a county centre Viljandi traditionally accommodates enterprises involved in food production. Enterprises involved in production of building materials are mainly situated in Männimäe industrial district, southwestern part of Viljandi. Assessing air quality, we mapped the distribution of indicator lichens and evaluated the state of lichens. 38 Folia Cryptog. Estonica In 1997 we conducted 252 analyses of lichen groupings on 126 trees in Viljandi – 68 on smallleaved lime (Tilia cordata Mill.) and 58 on Norway maple (Acer platanoides L.) bark of which has relatively similar properties to that of lime. The results of the study of lichen groupings in 1987 and 1991 were used for comparison. In 1987 we performed 94 analyses on 45 limes and 2 maples; in 1991 128 analyses were made on 57 maples and 7 limes. Mapping the distribution of indicator lichens on lime and maple, we used the plan of Viljandi on the scale of 1:10 000, where the town is divided into 500 × 500 m quadrats. In 1997 lichen groupings were analysed in 30 quadrats. All lichens in two, mostly N and S expositions at a height of 1.3 m on a tree were identified and their cover in per cent was estimated using a 20 × 20 cm grid, divided into hundred units of 2 × 2 cm. Additionally, we identified lichens on the trunk at a height of 0.5–2 m. Selecting the substrate, we followed the standardization requirements set for this method: we chose faultless, upright, solitary trees with the average circumference of 130 cm. Indicator lichens are selected and grouped according to differences in their relative toxicitytolerance, by comparing the frequency of lichens growing on lime and data on the coexistence of species in areas with comparatively different pollution levels in Estonia (Liiv, 1989 a, b; 1992). This selection of indicator species coincides largely with the scale of indicator species elaborated in other European countries by different methods and used for the bioindication of air quality (Skye, 1979; Hultengren et al., 1991; Hosiaisluoma, 1994; Hobohm, 1994; Wirth, 1995). By the compilation of the lichen-zonal map we based on the data of the distribution of the following indicator lichens: Hypocenomyce scalaris (Ach.) M. Choisy, Lepraria incana s.lat., Scoliciosporum chlorococcum (Graewe ex Stenh.) Vêzda, Hypogymnia physodes (L.) Nyl. tolerant to strong acidic air pollution (acidification of the substrate); Pseudevernia furfuracea (L.) Zopf., Platismatia glauca (L.) W.L. Culb. & C.F. Culb., Tuckermannopsis chlorophylla (Willd.) Hale, Vulpicida pinastri (Scop.) J.-E. Mattsson & M.J. Lai tolerant to moderate acidic air pollution; Phaeophyscia nigricans (Flörke) Moberg, P. orbicularis (Neck.) Moberg, Physconia enteroxantha (Nyl.) Poelt, Xanthoria candelaria (L.) Th. Fr., X. parietina (L.) Th. Fr. tolerant to strong alkaline dust pollution (eutrophication of the substrate) and acidic air pollution; Anaptychia ciliaris (L.) Körb., Melanelia subargentifera (Nyl.) Essl., Physconia distorta (With.) J.R. Laundon, Ramalina fastigiata (Pers.) Ach., R. fraxinea (L.) Ach., R. pollinaria (Westr.) Ach. tolerant to alkaline dust pollution but sensitive to acidic air pollution. RESULTS AND DISCUSSION In 1997 we identified 58 lichen species on lime and maple; the data on the distribution of 46 species are presented in a manuscript report (Liiv & Sander, 1997). In 1987, when we studied lichen flora mostly on lime, we identified 45 species in Viljandi, and in 1991 we determined 55 species predominantly on maple. Differences in the number of epiphytic lichens in Viljandi are mainly caused by the tree species under observation – the abundance of lichens growing on the maple with the subneutral bark is higher than on the lime with the subacidic bark. This was also confirmed by the results of the investigations of 1993–95 when we analysed lichen groupings on 693 lime and 777 maple trees growing outside the towns in parks of estates and country cemeteries. Basing on the distribution of indicator lichens, we distinguished four zones in Viljandi (Fig. 1). Zone I, the zone of lichens tolerant to strong acidic air pollution, is located in the centre of Viljandi. The area of the zone is about 0.4 km2. This zone is characterised by frequent occurrence of the indicators of strong acidic pollution H. scalaris, L. incana, S. chlorococcum and H. physodes on trees with the subacidic and subneutral bark. H. physodes grows on lime and maple also outside the towns, in parks of estates and country cemeteries (Table 1). The other three extremely toxicity-tolerant lichens H. scalaris, L. incana and S. chlorococcum have not been recorded on lime and maple outside the town areas. Poleophobous species sensitive to acidic pollution A. ciliaris, M. subargentifera, P. distorta, R. fastigiata, R. fraxinea and R. pollinaria, occurring commonly on lime and 39 Fig. 1. Lichen zones in Viljandi. I – zone of lichens tolerant to strong acidic air pollutions; II – zone of lichens tolerant to moderate acidic air pollution; III – zone of lichens tolerant to strong dust pollution; IV – zone of lichens sensitive to acidic air pollution. maple in relatively unpolluted air outside the towns, are completely lacking in zone I (Table 1, 2). Indicators of dust pollution are represented in zone I by P. orbicularis, P. enteroxantha, X. candelaria and X. parientina, but also by other comparatively toxicity-tolerant lichens as Buellia punctata (Hoffm.) A. Massal., Melanelia exasperatula (Nyl.) Essl., Lecanora carpinea (L.) Vain., L. chlarotera Nyl. and L. hagenii (Ach.) Ach. growing on eutrophicated substrate. In all, we identified 28 lichen species on lime and maple in this zone. However, lichens showing tolerance to acidic air pollution, e.g. Evernia prunastri and Ramalina farinacea or indicators of moderate acidic pollution P. furfuracea and T. chlorophylla, but also more tolerant Parmelia sulcata and H. physodes, are extremely tiny, strongly deformed and hidden in bark cracks, being on the verge of dying or already dead. The conditions are highly suitable for H. scalaris, S. chlorococcum and L. incana only. The mean general cover of lichens on trees of the quadrats analysed is only 4% in this zone. 40 Folia Cryptog. Estonica Table 1. Frequency (%) of indicator lichens on lime and maple in Viljandi in 1987, 1991 and 1997, and in Estonian parks outside the towns in 1993–95 Zone II, the zone of lichens tolerant to moderate acidic air pollution, comprises almost the entire northern part of Viljandi (Fig. 1). The area of the zone is about 6 km2 and it takes up most of Viljandi’s territory. This zone is characterised by the distribution of P. furfuracea, P. glauca, T. chlorophylla and V. pinastri, tolerant to moderate acidic pollution, also H. physodes, very tolerant to acidic pollution and P. orbicularis, P. enteroxantha, X. candelaria and X. parietina which are tolerant to alkaline dust and acidic air pollution, but also by poleophobous A. ciliaris, M. subargentifera, P. distorta, P. perisidiosa, R. fastigiata, R. fraxinea and R. pollinaria. Tolerant to strong acidic pollution H. scalaris and S. chlorococcum are missing in this zone. In all, 52 lichen species have been identified in zone II. Such a large number of lichens should be put down to the cemetery at Riia Road, but also to Viljandi Lossipark with great biomass. In this area poleophobous lichens grow side by side with indicators of moderate acidic pollution. Thus zone II represents a socalled transitional zone for lichens, showing the occurrence of poleophobous species as well as indicators of acidic air pollution. H. physodes has been identified even on 89% of trees (Table 2). Many dead lichens are found on trees as well. As a rule, the cover of lichens on trees is higher in relatively unpolluted air. The mean general cover of lichens is 20% in zone II, but the highest value of 26% is recorded in zone IV. Zone III, the zone of lichens tolerant to strong dust pollution, spreads mostly in two regions (Fig. 1). A 0.2 km2 area occurs as an island in the zone of moderate acidic pollution. The other dust pollution area of 2.2 km2 embraces most of the Männimäe industrial and residential district. On 89% of the trees examined in the socalled dust zone grow P. nigricans, P. orbicularis, P. enteroxantha, X. candelaria and X. parietina, tolerant to strong dust pollution and moderate acidic pollution (Table 2). Indicators of acidic pollution are represented in this zone by H. physodes and L. incana on single trees, but H. scalaris and S. chlorococcum, tolerant to strong acidic pollution, and P. furfuracea, P. glauca, 41 Table 2. Frequency (%) of groups of indicator lichen zones of Viljandi in 1997 T. chlorophylla and V. pinastri, which are tolerant to moderate acidic pollution, are lacking. The total number of lichen species is 32 in the dust zone, whereas on 44% of the trees grow also poleophobous, tolerant to dust pollution A. ciliaris, M. subargentifera, P. distorta, P. perisidiosa, R. fastigiata and R. fraxinea, which, however, are sensitive to acidic pollution. Zone IV, the zone of lichens sensitive to acidic air pollution, comprises the marginal areas of the town (Fig. 1). In the zone of relatively unpolluted air of Viljandi 30 lichens have been identified. The main indicators of this zone A. ciliaris, M. subargentifera, P. distorta, R. fastigiata, R. fraxinea and R. pollinaria, which tolerate weak dust pollution but are sensitive to acidic pollution, grow on 78% of the trees investigated for lichen groupings. The lichens indicative of dust pollution, which occur relatively frequently on lime and maple also outside the town areas, grow in this zone even on all trees (Table 1, 2). The lichen flora on lime and maple of Viljandi provokes a lot of interest as most of the town falls in the zone of moderate acidic pollution, where lichens of the trees with the subacidic and subneutral bark “compete” with the lichens characterising the trees with the acidic bark. This accounts for a relatively large number of lichens in zone II in comparison with the zones of lichens tolerant to dust pollution (III) or sensitive to acidic air pollution (IV). Lichens are relatively numerous also in the most polluted zone of Viljandi, as we considered as growing every at least recognisable or damaged lichen remain. A very expressive characteristic is the comparatively low cover of lichens which makes 4% in this zone. Moreover, most of this value represents the cover of crustaceous lichens P. argena and L. incana tolerant to pollution, or of H. physodes which is also very tolerant to acidic pollution. Considering the results of mapping of indicator lichens in 1987 and 1991, we note that the number of thalli of dead lichens as well as of damaged and mutilated lichens was greater in 1997. The location of the zones coincided in all three years. As compared to the years of 1987 and 1991, the frequency of some lichens 42 Folia Cryptog. Estonica indicative of acidic air pollution has increased (Table 1). The distribution of H. scalaris, the indicator of strong acidic pollution, has widened. In 1987 this species was not identified in Viljandi, in 1991 it grew on lime in the Park of Coloured Fountains. The frequency of H. physodes, L. incana and P. furfuracea has more increased on lime. The reason of lower increase on maple may be not only the differences of bark of different tree species but also a shorter time interval between maple-analyses (1991/1997) compared with lime-analyses (1987/1997). Among indicators of moderate acidic pollution of air V. pinastri was not identified on lime and maple in 1987 and 1991, but now it occurs in three town quadrats. Analyses of lichen groupings, performed mostly on maple in 1991, did not show the occurrence of P. furfuracea, which we identified on lime in two town quadrats in 1987 and in six quadrats in 1997. The distribution of toxicity-tolerant H. physodes has expanded considerably as well. These facts indicate the growth of acidic air pollution in Viljandi. Although for some years lichens stay inert in response to changes in air properties, we may affirm that air quality is constantly deteriorating in Viljandi, as the state of lichens has worsened practically in the whole town. More sensitive lichens, of which only fragments have preserved, are dying out. The intact exterior and great increment of lichens indicative of acidic pollution, however, give evidence of moderate and not strong acidic pollution in the most part of the town. Still, young thalli of poleophobous lichens were recorded nowhere in Viljandi. On the contrary, their cover has decreased almost everywhere, the state of lichens has deteriorated also on the outskirts.

However, after critical revision of herbarium material only 23 species, according to the present taxonomy, can be confirmed. In the last two decades 25 new to Estonia species have been found and thus, altogether 48 species are verified in Estonia today. In addition, two previously reported species are treated as doubtful because of the lack of vouchers. A map of the frequency of the species in different parts of Estonia is presented, and species that may occur in Estonia are discussed. Kokkuvõte: P. Lõhmus. Eesti kalitsioidsete samblike ja seente nimestik. 1970. aastate alguseks oli Eestist teada 34 kalitsioidse sambliku ja seene liiki (Trass, 1967, 1970; Sõmermaa, 1970). Pärast herbaarmaterjalide kriitilist läbivaatust, arvestades muutusi süstemaatikas ning lisades hilisemad andmed, võib Eestist tõestatuks lugeda 48 kalitsioidse sambliku ja seene liiki. Kahe liigi (Chaenotheca cinerea, Sclerophora peronella) esinemine Eestis jääb kaheldavaks, kuna varasem herbaarmaterjal puudub ja uusi leide seni pole. Võrreldes Trassi (1967, 1970) ning Sõmermaa (1970) esitatud nimestikega on lisandunud 25 liiki. Esmakordselt avaldatakse järgmised liigid: Calicium denigratum, C. parvum, Chaenotheca gracillima, C. laevigata, C. subroscida, C. xyloxena, Chaenothecopsis consociata, C. debilis, C. epithallina, C. nana, C. pusiola, C. savonica, C. viridireagens, Cyphelium sessile, Phaeocalicium populneum. Umbes 40% levikuruutudest (10’E–W × 6’N–S) on kogutud vähemalt üks kalitsioidse sambliku või seene liik. Edasistel uuringutel võib praegustele lisanduda veel vähemalt kümme liiki. INTRODUCTION Trass (1967, 1970) and Sõmermaa (1970) reported a total of 34 species of calicioid lichens and fungi from Estonia. During the last decades new species have been added and some previously published species were redetermined. The aims of this paper are (1) to check critically the species in Trass (1967, 1970) and Sõmermaa (1970), (2) to compile an updated list, (3) to discuss the state of knowledge about Estonian calicioid lichens and fungi, and (4) to present the species that may occur in Estonia. MATERIAL AND METHODS The study is based mainly on the material of calicioid lichens and fungi kept in the herbaria of the University of Tartu (TU), the Botanical Garden of Tallinn (TBA), the Institute of Ecology in Tallinn (IE), the University of Helsinki (H) and the University of Riga (RIG). Altogether over 1700 specimens were examined, 740 of them were collected by the author within the last three years. The morphology and anatomy of the lichens were studied with a stereo lens and light microscope, and the colour tests of apothecia were made with 10% KOH, 50% nitric acid and Lugol’s solution. For identification the following publications were used: Foucard (1990), Purvis et al. (1992), Tibell (1975, 1976, 1978, 1980). Additional comparsion material was received from H. The nomenclature follows Santesson (1993), the abbreviations of authors’ names are given according to Kirk & Ansell (1992). The herbarium data were sorted with the computer program BRAHMS. To illustrate the distribution of collected material, a map was compiled with the DMAP 6.4 program for Windows. As a record unit a square 10'(E–W) × 6'(N–S) was used. Using the species lists of the 15 best studied squares (with more than 10 species in each; representing a total of 37 species) the rate of discovery of new species is shown. For this purpose the lists were taken at random and for each list the number of new species (not recorded in previous lists) was determined. RESULTS After critical revision of herbarium material only 21 species of calicioid lichens and fungi presented in Trass (1967, 1970) and Sõmermaa (1970) can be confirmed according to the 44 Folia Cryptog. Estonica present taxonomy. Furthermore, the occurrence of four species (Chaenotheca cinerea, C. chlorella, C. hispidula, Sclerophora peronella) could not be confirmed, because voucher material was not found. However, Chaenotheca chlorella and C. hispidula have been collected later again. Two additional species are not known from Estonia with certainty. The following species were excluded from the lists in Trass (1967, 1970) and Sõmermaa (1970) because of previous uncorrect identification: Calicium corynellum was redetermined (®) as Microcalicium arenarium (det. V. Räsänen; RIG), C. lenticulare ® C. abietinum and C. glaucellum (det. P. Lõhmus; TU), all specimens (except three) of Chaenotheca chlorella ® Chaenotheca phaeocephala (det. P. Lõhmus; TU), Chaenothecopsis faginea ® C. pusilla (det. P. Lõhmus; TU), C. viridireagens ® C. epithallina (det. A. Titov; TU), Phaeocalicium populneum ® Mycocalicium subtile and Chaenothecopsis consociata (det. P. Lõhmus, A. Titov; TU). Some of these taxa were later found as new to the Estonian lichen flora. List of calicioid species in Estonia A checklist of Estonian calicioid lichens and fungi is compiled. New taxa for Estonia (compared with Trass 1967, 1970; Sõmermaa 1970, taking into account redeterminations) are given in bold; doubtful species are marked with ?. As synonyms only these names are added which have been used in Trass (1970) and Sõmermaa (1970). In the right column the total number of records in Estonia in 1998 is presented. CALICIUM Pers.

Most common species (over 50 localities) are Calicium glaucellum, C. viride, Chaenotheca chrysocephala, C. ferruginea, C. furfuracea, C. trichialis, Mycocalicium subtile. Twelve species – Calicium denigratum, Chaenotheca gracillima, Chaenothecopsis debilis, C. pusiola, C. subparoica, C. vainioana, C. viridireagens, Cyphelium lucidum, C. sessile, Phaeocalicium populneum, Sclerophora coniophaea and Sphaerophorus globosus – have been found only once or twice. In the present list 25 species are new to Estonia, compared to Trass (1967, 1970) and Sõmermaa (1970). Eleven of these have already been published by Randlane (1978, 1986; Chaenotheca phaeocephala, Cyphelium inquinans), Ekman et al. (1991; Calicium glaucellum, Chenothecopsis subparoica, C. vainioana, Microcalicium disseminatum, Sclerophora coniophaea, S. farinacea, Thelomma ocellatum), Nilson et al. (1997; Cyphelium lucidum) and Thor et al. (1998; Cyphelium sessile). A.Titov, having checked some TU herbarium material of calicioid lichens and fungi in 1984, identified Chaenotheca subroscida, C. xyloxena, Chaenothecopsis consociata, C. epithallina and C. pusiola for the first time. My revisions of all herbarium material and additional fieldwork in 1995–1997 added Calicium denigratum (leg. H. Ting, 1963), C. parvum (leg. A.-L. Sõmermaa, 1967), Chaenotheca gracillima (leg. P. Lõhmus, 1997), C. laevigata (leg.A.-L. Sõmermaa, 1967), Chaenothecopsis debilis (leg. I. Jüriado, 1996), C. nana (leg. P. Lõhmus, 1997), C. savonica (leg. P. Lõhmus, 1996), C. viridireagens (leg. P. Lõhmus, 1997) and Phaeocalicium populneum (leg. M. Sarv, 1995) to the list. DISCUSSION A map of the geographical frequency of all calicioid lichens and fungi species in Estonia is presented where the squares are numbered according to the abundance of species in the squares (Fig. 1). Altogether in ca. 40% of squares at least one species has been collected, this indicates that thorough investigations have been Fig. 1.

For the analysis the squares were taken in random order. done only in a few regions. The best studied areas are Alam-Pedja Nature Reserve (22 species are known in 260 km²), Endla Nature Reserve (18 species in 81 km²) and Poruni primeval forest with its surroundings (16 species in 0.5 km²). Preferred habitats for calicioid lichens and fungi (mire complexes, old deciduous forests and abandoned homesteads) are typical for these areas. The knowledge of calicioid flora in central Estonia and mainland western Estonia is still very poor and needs more attention in the future research. An analysis of the rate of discovery of new species has been carried out in 15 best studied squares (Fig. 2). After the first decline the rate of adding new species has remained stable in Estonia, i. e. a significant part of calicioid lichens and fungi seems to have been not found yet. In southern Finland 63 species (Vitikainen et al., 1997; biogeographical provinces No. 1–7) and in Latvia 23 species (Piterans, 1982, pers. comm.) are known. Considering the distribution and habitats of the species in these lists, I guess that at least Calicium adaequatum, C. lenticulare, Chaenothecopsis hospitans, C. viridialba, Cybebe gracilenta, Cyphelium notarisii and Sphinctrina anglica might be found in Estonia. Probably about ten species are as yet not discovered in Estonia. ACKNOWLEDGEMENTS I am grateful to the curators of herbaria H , IE, RIG and TBA. My warm thanks are due to A.

INTRODUCTION Estonian lichen flora is relatively well studied and includes about 800 species (Trass, 1970). The last review and identification key “Macrolichens of Estonia” (Trass & Randlane, 1994 ) includes records of 332 species of macrolichens. Among them, 42 species have been recorded before 1950 and are considered as extinct from the Estonian lichen flora. In this review, 131 species are registered as epiphytic macrolichens (excluding the genus Cladonia), and 20 of them have not been recorded after 1950. A. Sõmermaa (1972) published a monographic study on the ecology of epiphytic lichens in the main Estonian forest types. In her study the distribution of 26 epiphytic macrolichen species (excluding the genus Cladonia) in different forests was described. The latest review of forest lichens in Estonia was presented by H. Trass (1996) in the study of Estonian natural (old-growth) forests flora. He presented data on the distribution and frequency of 95 lichen species that are considered as indicators of virgin forests. This list includes 47 epiphytic macrolichen species. The main goal of the present study is to make an inventory of epiphytic macrolichen flora in the Estonian forests and to evaluate and quantify the frequency of epiphytic macrolichens. In 1994–1997 lichen data were collected under the co-operative Baltic–US Forest Ecological Monitoring Project and Estonian State Environmental Monitoring Program. This is the first paper in a series of publications to analyze different aspects of lichen species distribution in relation to structure and composition of Estonian forests. MATERIAL AND METHODS The general methodology and the forest sample plot design are described in ”Forest Health Monitoring Field Methods Guide (International)” (1994, 1995, 1996) and in “Forest Ecological Monitoring in the Baltic Countries” (1996). According to this methodology forest stand was considered as a forested area of more than 0.4 ha and sample trees were >12.5 cm in diameter. Sample plots in the forested areas were selected by a randomized sampling grid (Overton et al., 1990 ). The locations of sample plot centers were estimated using satellite and topographic maps. In the field the location of sample plot was identified by a GPS unit. 48 Table 1. Macrolichen species recorded for Estonian forests Folia Cryptog. Estonica 49 50 Folia Cryptog. Estonica Fig. 1. Forest epiphytic macrolichens sample plots. The lichen sample area (“lichen plot”) was a circular area with 34.7 m radius (0.378 ha) around the forest sample plot center. On each lichen plot the occurrence of the lichen species on different tree species (at least 10 trunks of each tree species) was noted. Macrolichens were recorded at a height of more than 0.5 m from the tree base up to 2.5 m and separately for twigs of Picea abies. In addition, six sampled forest sites along the air pollution gradient crossing Estonia from northeast to south-west (Martin et al., 1994) were included in the database (Table 1). In this study 2328 tree trunks were observed. The lichen species were recorded on fourteen tree species including Coryllus avellana, Malus sp. and Juniperus communis. The most frequent tree species in this sample was Pinus sylvestris (71 plots) and the least frequent Tilia cordata (1 plot). Location of the 116 sampled forest sites is shown in Fig. 1. During the field work, more than 1000 lichen samples were collected for identification in the laboratory. The nomenclature presented by R. Santesson (1993) was followed. Similarity of epiphytic lichen cover species composition registered on more frequent phorophytes was calculated by Sørensen’s similarity coefficient. The classification of geographical elements proposed by H. Trass (1970) was used for macrolichen flora characterization. The collected specimens were deposited in the Herbarium of the International Center for Environmental Biology, Tallinn (ICEB). RESULTS In the studied forests 57 macrolichen species were identified and total number of macrolichen records selected by substrate types (phorophytes) was 1164 (Table 1). The highest similarity in lichen vegetation was found between Pinus sylvestris trunks and Picea abies twigs (Table 2). The lowest similarity value was between Picea abies twigs and Populus tremula. Using the data presented in Table 1 the lichen species frequency classes’ intervals were calculated using the following formula: where c is frequency class interval, xN – maximal variant (99, number of records for Parmelia sulcata), x1 – minimal variant (x1 = 1) and N – number of observations (number of species, N = 57). The calculated class interval was 15 51 Table 2.

Frequency class 1 was further divided into two subclasses: 1a (1 record) and 1b (2–15 records). Using the data presented in Table 1 and the calculated frequency class intervals a lichen species frequency distribution curve was created (Fig. 2). The recorded epiphytic lichen species were divided into 7 classes. Several rare and floristically interesting lichen species are included in frequency class 1. Some of the new findings of these species are described below. Picea abies, trunks Betula spp. Alnus incana Alnus glutinosa Populus tremula 1 0.621 0.513 0.364 0.233 1 0.510 0.356 0.400 1 0.538 0.500 1 0.333 1 Lichen species in frequency class 1a ( 10 species, 18%) are as follows. Alectoria sarmentosa*, a very rare holarctic epiphyte, in Estonia previously recorded once in 1930. In the current study this lichen species was found on Picea abies twigs (North-East Estonia, Alutaguse, Kivinõmme, HEX 104386, 59°08’48”N, 27°30’18”E) in spruce-pine-birch mixed stand, age >120 years (Fig.1.). Lobaria pulmonaria*, a nemoral species, recorded locally over the whole territory of Estonia on deciduous trees, mostly in broad-leaved Fig. 2. Frequency distribution of the epiphytic macrolichen species in the studied forests. * Asterisk indicates lichen species, which are included in the draft proposal for the Red Data Book of Estonia. 52 Folia Cryptog. Estonica mixed spruce forests. In this study, L. pulmonaria was recorded once on Populus tremula (North-East Estonia, Oonurme, HEX 106135, 59°07’21”N, 26°57’46”E) in spruce-pine-birchaspen mixed stand, age >120 years. Usnea fulvoreagens, a boreal lichen, has been found earlier in Estonia in less than 20 localities. In this study U. fulvoreagens was found on Picea abies (Vetla, HEX 111451, 59°12’23”N, 25°29’19”E) in spruce-pine stand, age >120 years. Usnea scabrata*, a boreal lichen, has been recorded earlier in Estonia for more than 20 localities. In present study U. scabrata was recorded on Alnus glutinosa (Hageri–Adila, HEX 115043, 59°09’04”N, 24°35’15”E). Frequency class 1b (32 species, 56%) includes also some rare lichen species in Estonia. First of all, Bryoria furcellata – new for the lichen flora of Estonia species (Randlane et al., 1997) and up to now has been recorded 7 times for 6 localities in Estonian forests (Aegna: 59°34’31”N, 24°45’49”E; 59°34’52”N, 24°45’25”E; Naissaar, 59°34”54”N, 24°31’10”E; Nõva, 59°13’53”N, 23°38’21”E ; Tallinn, Kloostrimetsa, 59°28’12”N, 25°02’16”E; HEX 113220, 59°32’08”N, 25°36’16”E): 5 records on Pinus sylvestris, 1 on Betula pubescens and 1 on Picea abies twigs. This species was always found in similar habitats in open forests on sandy soils in the coastal zone ( Fig. 1 ). Hypocenomyce friesii, a boreal lichen, and in Estonia recorded earlier for three localities. In the current sample this lichen was also recorded three times for Pinus sylvestris (Aegna, 59°34’52”N, 24°45’25”E; 59°34’49”N, 24° 45’46”E; Naissaar, 59° 34”54”N, 24° 31’10”E). Menegazzia terebrata*, a rare submontaneous lichen, was found on the same forest plot as A. sarmentosa on Betula pubescens, Alnus glutinosa, and Salix caprea (Fig.1). Several interesting and relatively rare microlichen species were also collected here, i.e. Dimerella pineti (Ach.) Vêzda, Lecanactis abietina (Ach.) Körb., Mycoblastus sanguinarius (L.) Norman, etc. M. terebrata is considered as endangered in Europe (Trass, 1997). In Estonia this lichen was earlier known from 6 localities. Physcia semipinnata*, a nemoral epiphytic lichen, usually found on trunks of broad-leaved trees (less than 10 records in Estonia). In this study P. semipinnata was found on three forest plots in South-Eastern Estonia (Fig.1): twice on Populus tremula ( HEX 99245, 58°00’18”N, 27°08’37”E; HEX 100966, 58°08’51”N, 26° 46’ 00”E) and once on Salix caprea (HEX 102700, 57°57’03”N, 26°05’43”E). In addition to the species listed above, in frequency class 1 were included: (1) lichen species which usually grow in old forests on conifers and Betula spp. – Bryoria capillaris , B. fuscescens , B. nadvornikiana , B. subcana , Hypogymnia farinacea , Melanelia olivacea, Parmeliopsis hyperopta, Tuckermannopsis sepincola, Usnea filipendula; (2) species usually inhabiting on deciduous trees such as Anaptychia ciliaris, Melanelia exasperata, M. exasperatula, M. fuliginosa, M. subargentifera , M. subaurifera, Phaeophyscia ciliata, P. nigricans , P. orbicularis, Physcia adscendens, P. aipolia, P. stellaris, P. tenella , Physconia distorta, P. enteroxantha, P. perisidiosa, Ramalina baltica, R. fastigiata, R. fraxinea, R. pollinaria , Xanthoria fulva, X. parietina, X. polycarpa. In some cases listed species were found on not typical for them substrata (for example, Physcia tenella on Pinus sylvestris, on twigs and trunk of Picea abies, Xanthoria parietina on P. sylvestris, X. fulva on P. abies). Frequency class 2 (4 species, 7%) includes lichen species that are locally common in different habitats but relatively rare in the sampled forests: Evernia prunastri, Hypocenomyce scalaris , Tuckermannopsis chlorophylla, Usnea subfloridana. Frequency class 3 (3 species, 5%) includes lichen species common in old coniferous forests Hypogymnia tubulosa, Imshaugia aleurites and Ramalina farinacea found on twigs of spruces as well on trunks of deciduous trees. Frequency class 4 (1 species, 2%) has only one relatively frequent species for Picea abies, Pinus sylvestris and Betula spp. – Usnea hirta. Frequency class 5 (3 species, 5%) includes group of species that are typical for forests: Platismatia glauca, Pseudevernia furfuracea, Vulpicida pinastri. Frequency class 6 (2 species, 4%) includes a frequent for several phorophytes lichen Parmeliopsis ambigua, and several species of Cladonia usually inhabiting on tree base but sometimes climbing up on trunk. Frequency class 7 (2 species, 4%) includes multiregional and very frequent in forests Hypogymnia physodes and Parmelia sulcata. 53 Fig. 3. Distribution of the epiphytic macrolichen species belonging to different geographic elements in the studied forests. The sampled forests epiphytic macrolichen lichen flora (Fig. 3, column 1) consists of 39% boreal species, 30% nemoral species, 18% multiregional species, 9% holarctic species, and 4% submontaneous species. Lichen species in the frequency class 1 belong to the 5 geographic elements (Fig. 3, column 2). In the higher frequency classes (2 to 7) species of the submontaneous geographic element were absent and the percentage of boreal and multiregional species was higher (Fig. 3, column 3). DISCUSSION Lichens are considered as excellent biomonitors of change in air quality, climate change, and change in the structure of the forest community. Indicative value of lichen communities variables, such as presence/absence, frequency, coverage, etc. has been recognized by many researchers (Alstrup, 1996; Goward, 1992; Kuusinen, 1994, 1996; McCune, 1993; Smith, et al., 1993; Trass, 1996). Decreasing area and continuity and increasing fragmentation of forests due to forest management have led to the situation where many forest lichen species are in danger. For example, about half of the 138 endangered lichen species in Finland belong to the forest lichens ( Kuusinen, 1996). H. Trass (1997) presented the list of lichen species and their frequencies in 5 grade scale found in natural forests in Estonia. Most of macrolichens included in this list were recorded in present study but with lower frequency values (mostly in our frequency classes 1 and 2). It means that so-called indicator or typical species of the old or natural forests become rare in other forested areas. For example, such species are: Bryoria capillaris, B. fuscescens, Hypogymnia farinacea, Lobaria pulmonaria, Melanelia fuliginosa, M. olivacea, Menegazzia terebrata, Parmeliopsis hyperopta, Tuckermannopsis sepincola, Usnea fulvoreagens, U. scabrata. From 21 common species in these two studies only Platismatia glauca and Vulpicida pinastri had comparable values of the frequency. Although the lichen species distribution and vegetation of the boreal forests has been studied quite extensively in Northern Europe, there is limited number of published data with which the present results can be compared. P.-A. Esseen (1981) found 18 macrolichens on Pinus sylvestris and 24 on Picea abies in Central Sweden (middle and southern boreal subzones). 54 Folia Cryptog. Estonica A. Sõmermaa (1972) surveyed the epiphytic lichen vegetation of several forest types in Estonia (hemiboreal zone, Ahti et al., 1968), where the number of epiphytic macrolichen species (except Cladonia) on P. sylvestris was 23, P. abies 19, on Betula pendula and B. pubescens 17, and 14 on Alnus glutinosa. M. Hyvärinen et al. (1992) described 32 macrolichen species on P. sylvestris including 14 Cladina and Cladonia species, and 23 on P. abies including 8 Cladonia species. Differences between the total numbers of epiphytic macrolichen species recorded by A. Sõmermaa, P.-A. Esseen and M. Hyvärinen et al. and in present study are relatively small, approximately 7 lichen species per tree species in average. At the same time the comparison of the species percentage frequencies established in present study and presented by M. Hyvärinen et al. (1992) for Muhos (Oulu region, the middle boreal zone) showed considerable differences. From 14 common species only three found on pines (Hypogymnia physodes, Parmeliopsis ambigua, Platismatia glauca) and two found on spruces (H. physodes, P. sulcata) had close frequencies. In central part of Finland frequency values for most of the macrolichen species were higher than estimated in present study. These differences could be explained partly by differnces in study site selection. M. Hyvärinen et al. (1992) as well A. Sõmermaa (1972) studied typical forests sites. In present study all sites were selected randomly and several forest plots were placed in transition areas. The epiphytic lichen vegetation is known to differ greatly between branches and trunks of conifers (Pike et al., 1975, 1977). The trunks of P. abies receive less light, which could be the main reason for the greater abundance of macrolichens on their branches than on the trunks. We found in literature just one publication concerning lichen distribution on P. abies branches (Hilmo, 1994). She recorded 16 macrolichen species on P. abies branches in central Norway. Comparison is difficult because of Bryoria and Usnea species were not identified and she studied mean cover of the lichen species on branches. In present study 27 macrolichen species were found on P. abies twigs. It is interesting to point out that the similarity between macrolichen species on the P. abies twigs and P. sylvestris trunks was higher than between P. abies twigs and trunks (Sørensen’s similarity coefficients respectively 0.8 and 0.76 ). Most of the recorded lichen species ( 42 species or 74 %) had relatively low frequency (class 1). The most frequent lichen species in sampled forests belonged to the nemoral, boreal and multiregional geographic elements, which may be due to their wide amplitude to habitat conditions.

The most wide-spread and frequent lichen species are those indicating eutrophication of bark substrate. Commonly overlooked crustose species are shown to be quite frequent, whereas some more easily detectable species common for pine in the mainland part of Estonia are rarely met on the islets studied.

INTRODUCTION The lichen flora of the islands at the northern coast of Estonia was very poorly known until recently. During the Soviet time the islands belonged to the closed frontier zone and were nearly inaccessible for scientists. Up to now, the lichen species list is published for Naissaar (Randlane et al., 1997). Kolga bay at the northern coast of Estonia has the greatest concentration of small islands (islets) in this area (Figure 1). The islets are situated between 59°30’–59°40’N and 25°10’– 25°30’E. They belong to the landscape region of North-Estonian Coastal Lowland (Varep, 1964) and to the corresponding geobotanical region of Northern Maritime Estonia – Estonia maritima borealis (Lippmaa, 1935). Administratively the islets belong to the municipalities of Jõelähtme and Kuusalu, Harjumaa County. The islets lie on Vendian and Cambrian sedimentary rocks covered with Quaternary deposits of various composition (Karukäpp & Malkov, 1993). The prevalent landforms are plains, escarpments, terraces and dunes. Northern and western coasts of the islets are characterised by presence of escarpments and coarse-grained Fig. 1. Location of the islets of Kolga bay. 58 Folia Cryptog. Estonica sediments (cobbles, boulders), while southern and eastern coasts are normally flat and sandy (Lepland, 1995). Parent material of soils (marine and aeolic sands, coastal deposits consisting much crystalline pebble) is poor in calcareous matter. Soils are mainly podzols, sod-podzolic soils, gley-podzols and saline littoral soils. Species diversity of flora and vegetation types of the islets depend on age, area, elevation a.s.l. and landscape diversity of the islets, as well as on their management history and the influence of seabird colonies (Ratas et al., 1995). Smaller islets (Allu, Põhja-Malusi, Vahekari and Umblu) carry heavily bird-influenced, fragmentary and sparse herbaceous vegetation. Various types of woody vegetation that make possible the occurrence of epiphytic lichens are met on five bigger islets (Lõuna-Malusi, Rohusi, Koipse, Pedassaar and Rammu). A grove of young aspen trees (Populus tremula L.), some older trees of mountain ash (Sorbus aucuparia L.) and Scots pine (Pinus sylvestris L.), as well as a number of juniper (Juniperus communis L.) and elder (Sambucus racemosa L.) shrubs are met on Lõuna-Malusi. One third of the area of Rohusi island is covered with pine forest with the undergrowth of mountain ash and elder. Old trees of mountain ash, aspen, black alder (Alnus glutinosa L.) and goat willow (Salix caprea L.) are met on forest edges near the seashore. Woody vegetation is represented mostly by juniper scrub on Koipse. A grove of deciduous trees on this island consists of aspen and birch (Betula pubescens Ehrh.), while conifers are represented by some single trees of Scots pine and Norwegian spruce [Picea abies (L.) Karst.]. The Calluna – Empetrum heath in the southern part of the islet has been planted with pine seedlings in 1987–88. Pedassaar, the second largest islet of the group examined, has nearly 98% of its territory covered with dry pine forests with the undergrowth of mountain ash and juniper. Black alder, aspen, mountain ash and goat willow are met on forest edges. The largest islet, Rammu, carries two small pine groves of natural origin, surrounded by developing juniper scrub – one around a little lakelet in the central part and another on a long sandy spit extending to southeast. Deciduous trees are very scarce on this islet. The Empetrum heath in the eastern part of the islet is afforested with pine seedlings. For the islets of Kolga bay the following lichen species are mentioned in earlier literature: Cladina arbuscula (Wallr.) Hale & W. L. Culb., Cladina rangiferina (L.) Nyl., Cladonia fimbriata (L.) Fr. (Rebassoo, 1987); Cetraria islandica (L.) Ach., C. nivalis (L.) Ach., Tremolecia atrata (Ach.) Hertel, Xanthoparmelia mougeotii (Schaer. ex D. Dietr.) Hale (Nilson & Piin, 1993); Cyphelium lucidum (Th. Fr.) Th. Fr. and Peltigera scabrosa Th. Fr. (Nilson et al., 1997). In the 1990s the Kolga Bay Islets’ Nature Reserve (consisting of ten islets) was established to protect breeding bird populations and rare or interesting plant communities. For conservation of any group of organisms basic information on distribution diversity and dynamics is needed. Representative data on the frequency of epiphytic lichens is of key importance when these organisms are used as bioindicators of air pollution or when Red Lists are to be established Table 1.

The first part of our lichen studies on the islets of Kolga bay deals with distribution and frequency of most common epiphytic lichens, based on floristic data. The similarity of epiphytic lichen flora of different islets is briefly discussed, as compared with the data on vascular plants and bryophytes. MATERIAL AND METHODS The material (820 herbarium specimens) was collected on the islands of Kolga bay mostly in 1991 and 1993 and is kept in the Herbarium of Tallinn Botanic Garden (TBA). Each piece of bark was examined carefully and not only the species for what it was collected, but all accompanying species were identified or recorded as well. In all 2890 identifications and checking of epiphytic lichens (140 species) were made by the second author. The nomenclature of lichen species follows mainly Santesson (1993). The lichens were collected on 9 woody plant species: Pinus sylvestris (57 trees), Juniperus communis (10), Sorbus aucuparia (21), Populus tremula (5), Alnus glutinosa (5), Betula pubescens (2), Salix caprea (5), Syringa vulgaris (1), Sambucus racemosa (1), altogether on 109 trees or shrubs. Some numeric characteristics of the islets of Kolga bay, the number of epiphytic lichen species recorded on each islet included, are represented in Table 1. RESULTS AND DISCUSSION The highest number of corticolous lichen species has been recorded from the islets of Pedassaar (79) and Rohusi (74) that are covered with forest in great extent. Table 2 includes more frequent lichen species (5 or more records), showing their distribution on the islets and on the most common phorophytes. Sorbus aucuparia, Pinus sylvestris and Alnus glutinosa are the phorophytes that carry the highest number of lichen species. Lecanora hagenii, L. symmicta, Physcia tenella, Scoliciosporum chlorococcum and Xanthoria polycarpa are ubiquitous lichen species inhabiting the islets of Kolga bay. They are met on all kinds of phorophytes on all islets. The named species belong to the rich bark species (Du Rietz, 1945) and their occurrence on normally nutrient-poor and acidic bark (incl. that of conifers) indicates bark eutrophication under the influence of seawater aerosols and ammonia derived from bird excrements. Hypogymnia physodes and Parmelia sulcata are also very frequent and are found on their usual bark substrates, as well as on boulders and on sand of coastal grey dunes. Table 3.

Estonica Owing to careful examination of every piece of bark, many crustose species, such as Amandinea punctata, Catillaria nigroclavata, Cliostomum griffithii, Rinodina pyrina, R. sophodes, that could be easily overlooked in field are recorded with quite high frequency. Some easily detectable epiphyte species, characteristic to pine in the mainland part of Estonia, such as Chaenotheca ferruginea, Hypocenomyce scalaris (Ach.) M. Choisy, Parmeliopsis ambigua, Platismatia glauca (L.) W.L. Culb. & C.F. Culb., Pseudevernia furfuracea and Vulpicida pinastri were rarely met on pines on the islets of Kolga bay. Similarities of vascular plant and bryophyte floras are compared between four islands (Tables 3 and 4), Lõuna Malusi is left out. The island is inhabited with large seabird colonies that have influenced the vegetation heavily by trampling and manuring, so the species diversity of ground vegetation is much lower on Lõuna Malusi than on other islets (see Table 1). As epiphytic lichens are more independent on bird activities, Lõuna Malusi is included into the analysis of similarity of lichen floras (Table 5). The data in the Table 3 allows to conclude that there are no big differences between the Sørensen’s coefficients of similarity between the islets in regard of the composition of vascular plant floras. The most dissimilar are floras of Rammu and Pedassaar. It concerns vascular plants (similarity 56 %), as well as bryophytes (46%) and epiphytic lichens (44%). These two largest islets have nearly equal areas, but differ largely in landscape diversity and dominant vegetation types (Ratas et al., 1995). The most similar are the bryophyte (65%) and especially the epiphytic lichen (87%) floras of Pedassaar and Rohusi islets, although the area of Rohusi is less than 1/8 of Pedassaar. Pine forest is dominant and fairly extensive on both islets and the same species of deciduous trees are spread on forest edges along the shoreline.

INTRODUCTION In Estonian towns and along roadsides, thalli of Xanthoria parietina, Physcia tenella and several other lichens are sometimes “moldy”, damaged by a fungus. I have seen such lichens since 1943 when Hans Trass and me studied lichens together in our hometown Nõmme and avoided collecting such “bad” specimens. Only decades later I found out that the “mold” is not less interesting than its host lichens. TAXONOMY Athelia arachnoidea (Berk.) Jülich, Willdenowia Beih. 7: 53 (1972).

Good descriptions and figures: Jülich, 1972: 53, Fig. 8; Eriksson & Ryvarden, 1973: 103, Fig. 37; Poelt, 1975, Fig. 1; Arvidsson, 1976, Fig. 1; Gilbert, 1988, Fig. 1. Damaged by the fungus lichens and algae, but also surrounding tree bark is covered with thin and loose cobweb-like (arachnoid) white or slightly creamish mycelium. Later small white spherical granules (“sclerotia”) 0.2–0.7–(1) mm in diam. develop on mycelium in groups. Basidioma (fruit-body) of the fungus is similar but covered with thin pellicle formed by basidia. Microscopically both mycelium and basidioma consist of loosely interwoven thin-walled hyphae 3–7 µm in diam., which are branched under right angle; septa numerous, without clamps or with few clamps mainly on basal hyphae. The hyphae attached to and near the algal cells are up to 8 µm in diam., richly branched, somewhat torulose and with slightly monilioid short sidebranches. At the margin of a mycelium there are some straight very long hyphae. Basidia are clavate, 20–30 × 5–7 µm, with 2–4 (mainly 2) sterigmata. Spores are narrowly ellipsoid, thinwalled, 7–9–(10) × 3.5–5 µm. Basidiomata have been described in several monographs and key books without mentioning characteristic small white sclerotia. Reason for such an omitting is simple: only full-developed basidiomata have been described not paying attention to the surrounding these marginal area of aerial mycelium. Hyphae of this species have been described and figured as smooth, i. e. without crystals. In all specimens studied by me (about 30), several or many hyphae of mycelium, but sometimes 64 Folia Cryptog. Estonica also of basidiomata, are covered with short rodelike crystals of calcium oxalate-dihydrate as shown in Adams & Kropp (1996: 464, Fig. 5). RESULTS Distribution and hosts in Estonia A. arachnoidea has been found in almost all suitable places where it was searched for (Parmasto, 1995; Fig. 1). Typical localities are living trunks of deciduous trees (mainly Tilia cordata) and dead twigs of Syringa vulgaris on roadsides, at alleys and in parks. It is growing on many lichen species and protococcoid algae; Xanthoria parietina (L.) Th. Fr. and Physcia tenella (Scop.) DC. are the most common hosts in Estonia; it has been found also on Anaptychia ciliaris (L.) Körb., Lecanora conizaeoides Nyl., Melanelia exasperatula (Nyl.) Essl., Parmelia sulcata Taylor, Physconia distorta (With.) J.R. Laundon. A. arachnoidea has been seen since the 40ies of this century in Estonia but was never so widespread as during the last 5–8 years. For example, in Tartu more and more trees covered with lichens and algae are infected since the beginning of the 90ies. This is possibly caused by relatively warm winters with frequent and long thaw periods. Fig. 1. Localities of Athelia arachnoidea in Estonia. Cycle of development Late autumn and in winter, mycelium of A. arachnoidea is frequently seen on tree trunks as glittering white circles up to 40 cm long (Fig. 2); sometimes these circles unite and form an infected area up to 5 m along a trunk. When it is thawing after severe frosts, the circles appear again after some few days. In this stage, mycelium is web-like, loose, in many cases with white loose sclerotia turning brownish, and more compact later. Hyphae are always covered with numerous crystals; no basidia or free spores were seen. We have no collections of this species before May, but possibly they survive. From July, mycelium can be seen on lichens again. Pellicular hymenium with developed and spore-bearing basidia has been seen in 3 specimens (of 30), namely in August and September. First, usually small and white sclerotia can be seen rarely in August, frequently in September and later. DISCUSSION Taxonomy of the Athelia epiphylla-complex is unclear; several species have been described based on small differences in spore form and size without any statistical study on variability of these characters. Under the name A. arachnoidea fungi growing parasitically on lichens or algae, and on wood (bark) have been united. There is also another species found sometimes on lichens, A. epiphylla. Main difference between these species is that basidia of A. arachnoidea have usually two sterigmata (and spores), A. epiphylla – four. This is a vague character: most of the specimens growing on lichens and algae are sterile, i. e. without basidia and spores. Among Estonian specimens there are some with almost equal number of 2- and 4-spored basidia (TAA 152154, 152433). The specimens collected in Estonia are similar to each other, and support J. Eriksson’s (in Arvidsson, 1976) and Arvidsson’s idea that only one species in this species group is growing on lichens and algae, characterized by the production of sclerotia. Correct name for this taxon is A. arachnoidea: its type was “creeping over mosses and lichens on fallen sticks”. However, this species has been found also on 65 Fig. 2. White-margined lesions on algal cover on a lime tree, formed by Athelia arachnoidea. Tartu, 18 Jan 1998. Photo by E. Parmasto. dead leaves of deciduous trees, and I have seen it spreading from lichens to surrounding tree bark and wood. Diederich (1986) mentioned that he had not seen specimens with fructifications (= specimens with developed hymenium) in Luxembourg. During two-years’ observations in Sheffield area (Great Britain), Gilbert (1988) did not observe any spores produced by this fungus. In Estonia, of the 30 specimens studied only one has quite well developed hymenium. Possibly the main way of distribution in this species is by sclerotium-like propagula which are loosely attached to mycelium, as said already by Poelt (1975: 7). There are two ecological peculiarities in A. arachnoidea. In Estonia, it has been found only in anthropogenic localities, never in “wild” forests. According to Arvidsson (1976: 7), “the parasite appears to be less common outside towns or in areas with no air pollution”. Poelt & Jülich (1969) described it as found in Berlin, but also in forests near the city. Only in England, the fungus is widespread in open woodland as well as in valley bottoms (Gilbert, 1998: 183). Another interesting feature is vigorous growth of its mycelium at low air temperature (in Estonia, at about 1–4 ºC in winter). Air pollution and low temperature seem to weaken lichens and algae infected thereafter with A. arachnoidea. In England, radial extension of the mycelium occurred only during the winter months from November to February (Gilbert, 1988: 185). As demonstrated by Adams & Kropp (1996), anamorphic state of this species, Fibulorhizoctonia (Rhizoctonia) carotae is a cold-storage pathogen of carrot in Europe, North America and India, developing mainly at temperature 1–3 ºC and 92–96 % relative humidity. These 66 Folia Cryptog. Estonica environmental conditions are the same as for development of the fungal mycelium and sclerotia on lichens in Estonia in wintertime. Occurrence of A. arachnoidea as an agent causing crater rot of carrot roots in their storage has not yet been studied in Estonia.

Ochrolechia szatalaënsis Verseghy was described from Bulgaria (Verseghy, 1958). An improved, detailed description was given by I. M. Brodo (1991). This corticolous lichen has an oceanic and suboceanic distribution in Holarctic Kingdom: Boreal and Tethyan Subkingdoms. O. szatalaënsis prefers bark of conifers (Picea, Abies) in Central and Southern Europe and bark of deciduous trees (Sorbus, Salix, Betula, Quercus, Corylus) in Western and Northern Europe (Purvis et al., 1994). The species occurs in western North America on bark and wood of different kinds including Betula, Alnus, Quercus, Pseudotsuga, and Thuja (Brodo, 1991). The nearest locations of this species to Estonia are in Gotland, Sweden (Santesson, 1993). The second author collected O. szatalaënsis in the northern part of our country, Raplamaa Co., in the vicinity of Märjamaa settlement (60 km south of the Gulf of Finland; 58°54’N 24°26’E) during a bioindication study in 1994. The specimen examined was found on the stem bark of Acer platanoides L. (exposition S, at the height of 1.5 m, not abundant) in Märjamaa Orthodox Cemetery (Herbarium of Tallinn Botanic Garden, TBA). The associated species included Lecidella elaeochroma (Ach.) M. Choisy and Pertusaria leucostoma A. Massal. O. szatalaënsis belongs to the upsaliensisgroup of Ochrolechia following I. M. Brodo (1991). Its good diagnostic features are the almost white, thin thallus, white-pruinose apothecia and discs (all UV+ and C+ yellow). This species is closely related to O. upsaliensis (L.) Massal., a common arctic-alpine terricolous lichen species. We suppose that this species belongs by its distribution pattern to holarctic suboceanic element in the lichen flora of Estonia (Trass, 1970). The detailed description of the specimen will given in future together with other Ochrolechia species in Estonia which are just under revision. The following species of Ochrolechia A. Massal. have been published for Estonia in former times: O. alboflavescens (Wulfen) Zahlbr., O. androgyna (Hoffm.) Arnold, O. arborea (Kreyer) Almb., O. frigida (Sw.)

The analysis of the results gathered in the course of the 1970s within the area of Vel’ký Rozsutec Mt., the Malá Fatra Mts, demonstrated intensifying antropogenous pressure. The contemporary research (1996–1997) confirmed 124 species, recorded 55 taxa new to the area and gave evidence of threat of 59 lichens (21.7%), enrolled in the local red list presented here. The process of impoverishment affects mainly epiphytes dependent on air humidity and the alpine muscicolous and terricolous taxa concentrated about the summit. Over the period of elapsed 25 years several toxitolerant, acidofilous and nitrofilous species emerged. Kokkuvõte: I. Pišút ja A. Guttová.

INTRODUCTION The National Nature Reserve (NNR) Rozsutec (734.74 ha), situated in the northern part of the Malá Fatra Mts, covers up the geobiological complex of the landscape dominant Vel’ký Rozsutec Mt. Its crest is built of dolomite and limestone both forming vivid mosaic of rock faces. The lower parts are of calcareous sandstone and schist. The vast area stretches within the altitude limits from 600 to 1610 m. The beech and fir forest formations, relict mountain maple woods and mountain pine belt with scattered spruce keep their natural character to a significant extent (Klinda, 1985). The average annual precipitation falls vary from 900 to 1000 mm; the average annual temperature amounts are from 2 to 5°C (Intribus, 1981). The NNR Rozsutec is exhaustively examined. The first notes date back to the second half of the 19th century (Brancsik, 1862). More intensive investigation started in the 1920s and 1930s (Servít, 1954; Servít and Cernohorský, 1935; Suza, 1926, 1934, 1943, 1944) and then in the 1960s and 1970s (Pišút, 1966, 1968, 1969, 1971, 1974; Vêzda, 1958, 1965a, 1965b, 1970, 1972, 1973, 1978). The collective information on the local lichenflora was presented by Pišút (1981). By 1973, 218 species were recorded (Pišút, 1981, 1992, 1996). In the meantime, the antropogenous influence upon this domain, exposed in terms of orography and tourism, increased. MATERIAL AND METHODS The study is based on two field visits in 1996 and 1997. The observations were guided by the steps given in Pišút (1981). The research conducted after 25 years is comparable. Floristic knowledge is updated as well. The species with localities are listed in Pišút & Guttová (1998, in press). Moreover, the adjacent area (the Vrátna dolina valley, Štefanová and Zázrivá villages) is included. Regarding the changes in the diversity of the lichenflora, which no way could be neglected, the local red list (Table 1) is elaborated. Material from BRA, SAV and SLO was studied and revised. The nomenclature as well as the categories of threat follow Pišút et al. (1996). The figures in the Tables 2, 3, 4 giving the number of species in the NNR and the surroundings, cannot be added up to obtain the total number, as some of the taxa occur in both areas. The specimens collected are at disposal at the Institute of Botany, Slovak Academy of Sciences, Bratislava (SAV). 70 Folia Cryptog. Estonica RESULTS AND DISCUSSION The isolated massif of Vel’ký Rozsutec Mt. (alt. 1606 m) functions as a natural barrier to emission particles transported mostly by northwestern winds. While in the first quarter of the 20th century this factor played minor role (the only eventual source of pollutants was Zilina, a town 26 km westward, with a population of less than 10,000 then), the 1950s were the turning point. Since 1952 Vel’ký Rozsutec Mt. has been attacked from smelters in Istebné (10 km SE), since 1965 from Široká (18 km E) and a couple of decades by emission generated in chemical, textile and power supply industries as well as engineering of 100,000-inhabitant Zilina. Vel’ký Rozsutec Mt., the distinct elevation, is the „ideal destination“ for long-distance emissions originating in the industrial area of Ostrava (80 km NW, Czech Republic) and Silesia (120 km, Poland). The field work in the 1970s documented the impoverished diversity of mostly epiphytic lichens, which was the great contrast looking back to 1920s and 1930s. Even in 1973 several more susceptible epiphytes died out (e.g. Bryoria bicolor, Collema fragrans, C. nigrescens, Evernia divaricata, Hypogymnia bitteri, Nephroma resupinatum, Normandina pulchella, Peltigera collina, Ramalina calicaris, Ramalina farinacea). The others, e.g. Graphis scripta, Lobaria pulmonaria, and the representatives of the genera Bryoria and Usnea were extremely rare. The remarkable thing was the extinction of the lignicolous species Cladonia botrytes, once not that uncommon. The contemporary research (1996–1997) gave evidence of the extinction or alternatively missing of Belonia herculina, Cetrelia cetrarioides, Hypogymnia bitteriana, Lecanora albella, L. intumescens, Lobaria pulmonaria, Ochrolechia alboflavescens, Pertusaria flavida, P. leioplaca, the Usnea species. The domination of the antropogenous influences over the epiphytic lichenflora, with consequences on its diversity, is supported by the following examples. 1. Suza (1934) examined Populus pyramidalis, P. tremula and Fraxinus excelsior between the villages Terchová and Zázrivá (north periphery of the Rozsutec Mt.), writing down subsequent taxa: Candelaria concolor, Collema fragrans, Leptogium saturninum, Parmelia caperata, P. exasperata, P. glabra, P. subargentifera, P. subaurifera, Phaeophyscia nigricans, P. orbicularis, Physcia stellaris, Physconia distorta, P. enteroxantha, P. grisea, Xanthoria candelaria, X. fallax, X. parietina. In 1996 we recorded here Physconia distorta, Xanthoria parietina (both with high cover degree), Candelariella reflexa, Lecania cyrtella, Parmelia submontana, Phaeophyscia orbicularis, Physcia tenella. 2. As for the north slope of Rozsutec (900–1000 m), Suza (1934) made reference to the occurrence of Lobaria pulmonaria, Nephroma resupinatum (rather abundant), Leptogium saturninum, Bryoria bicolor, Collema nigrescens, Graphis scripta, Hypogymnia physodes, Normandina pulchella, Parmelia glabratula, P. sulcata, Peltigera collina, P. praetextata, Platismatia glauca, Pyrenula nitida, Ramalina farinacea, all growing on Fagus sylvatica. In 1996 Lecanora argentata, L. carpinea, Graphis scripta (one thallus) and Pyrenula nitida (one thallus) were put on record on the south slope of the mountain (Fagus sylvatica). The east slope was slightly more varied with Cladonia fimbriata, Hypogymnia physodes, Lecanora conizaeoides, L. pulicaris, Parmelia glabratula, P. saxatilis, P. sulcata, Parmeliopsis ambigua, Phlyctis argena, Platismatia glauca, Pseudevernia furfuracea and Pyrenula nitida (rarely). In contrast to the elevations and the outskirts of the mountain region, one can find relatively rich epiphytic lichen flora at the protected lower altitudes. The Vrátna dolina valley, shielded by surrounding mountain ridges, illustrates the fact appropriately. Being a ski-centre, thus influenced by more or less heavy traffic, notwithstanding, one can still find Acrocordia gemmata, Anaptychia ciliaris, Bacidia rubella, Caloplaca cerina var. cerina, Caloplaca herbidella, Evernia prunastri, Lecanora allophana, Leptogium saturninum, Opegrapha varia, Parmelia caperata, P. flaventior, P. glabra, P. glabratula, P. pastillifera, Pertusaria albescens, Physconia distorta, P. perisidiosa and Xanthoria parietina growing on Fraxinus excelsior or Tilia parviflora (Guttová, 1997). 71 The diversity of muscicolous and terricolous lichens decreases, apparently, mainly on the top of Vel’ký Rozsutec Mt. and along the paths. In this case, antropogenous influences are found the crucial cause, although one cannot omit the role of emission from near and distant sources. Enormous rise in the number of tourists (the Malá Fatra Mts is on the 2nd position, right after the Vysoké Tatry Mts) has been bringing about not only direct trampling of the soil cover, but also a supply of nitrates. Even in the 1970s Pišút (1981) could not confirm the occurrence of several species such as Cetraria cucullata, C. nivalis, Omphalina hudsoniana, Pannaria pezizoides, Peltigera aphthosa, P. venosa and Thamnolia vermicularis. The investigation in 1996–1997 confirmed the increase in the antropogenous pressure and further decrease in lichen diversity. The species Arthroraphis citrinella, Biatorella hemisphaerica, Caloplaca sinapisperma, Cladonia macrophylla, Icmadophila ericetorum, Lecanora epibryon, Peltigera leucophlebia, Pertusaria glomerata, Vulpicida tubulosus were not found. In total, 59 lichen species (21.7%) are enrolled in the local red list (Tab. 1). Total account of the recorded species is given in Tables 2, 3, 4. Gradual acidification of the substrata in the 1970s is documented by the presence of Scoliciosporum chlorococcum, found at three localities, exclusively on Picea abies at 1200–1300 m. This acidophilous lichen was very rare in the late 1960s in Slovakia, up to 1970 known only from 11 grid squares (Pišút, 1985), as well as Lecanora conizaeoides and Hypocenomyce scalaris, typical invasively spreading acidophilous, toxitolerant lichens. The former species is now found on timber, Picea abies, Larix decidua, Abies alba and Fagus sylvatica at 700–1320 m. Similarly, the latter one grew on Picea excelsa, Table 1.

While the occurence of 15 indicatory species (IEK 15) in the 1920s and 1930s pointed at a high quality of the forest formations, the number of 8 in the 1970s (IEK 8) marked a poorer quality. The contemporary research gives only 4 taxa (IEK 4), which represents the area of poor quality, and supports the statements on increasing antropogenous pressure.

Kasutatud on järgmisi ohukategooriaid: 0 – hävinud või tõenäoliselt hävinud (18 liiki), 1– eriti ohustatud (5), 2 – ohualtid (24), 3 – haruldased (41), 4 – tähelepanu vajavad (21), 5 – määratlemata (1). INTRODUCTION According to our present knowledge the lichen flora of Estonia consists of about 800 species, out of which we have verified data about the distribution of 337 macrolichens. In addition, the occurence of more than 450 microlichen species is strongly suggested in our territory. The new checklist of Estonian lichen species will be completed at the end of this year as a result of a collective project. The revision of several microlichen genera has not been finished yet and, therefore, the inclusion of the microlichens into the red list is not considered to be scientifically justified at present. The following red list is based on data presented in Trass & Randlane (1994) and on herbarium materials collected or identified later. Specimens cited are kept at the International Center for Environmental Biology (ICEB), or the Institute of Ecology (IE), both in Tallinn; in the herbaria of the Universities of Helsinki (H), Tartu (TU) or Uppsala (UPS). A few changes in the checklist of Estonian macrolichens since 1994 should be pointed out. 1. Several species that were earlier considered to be extinct from the modern lichen flora of Estonia (Trass & Randlane, 1994), are now treated as doubtfully recorded. These species are: Bryoria bicolor (Ehrh.) Nyl., Collema auriforme (With.) Coppins & J.R. Laundon, Collema crispum (Huds.) Weber, Collema fluviatile (Huds.) Steudel, Dermatocarpon meiophyllizum Vain., Leptogium byssinum (Hoffm.) Nyl., Leptogium plicatile (Ach.) Leight., Melanelia elegantula (Zahlbr.) Essl., Parmotrema chinense (Osbeck) Hale & Ahti, Peltula euploca (Ach.) Poelt, Phaeophyscia constipata (Norrl. & Nyl.) Moberg, Physcia dimidiata (Arnold) Nyl., Physconia muscigena (Ach.) Poelt, Ramalina lacera (With.) J.R. Laundon, Umbilicaria grisea Hoffm., Umbilicaria proboscidea (L.) Schrad., Umbilicaria vellea (L.) Hoffm., Usnea articulata (L.) Hoffm., Usnea longissima Ach., Xanthoria elegans (Link) Th. Fr. These taxa had been included in the flora based on information in old literature (Bruttan, 1870, 1889; Mereschkowsky, 1913; Räsänen, 1931). Unfortunately, we have not seen any herbarium specimens of them (possibly the specimens are not preserved) and cannot verify the identifications according to modern taxonomy. Still, we cannot convincingly exclude them either, as their occurrence in Estonia is chorologically possible. Therefore, a special category of species – doubtful (marked with ?) – is introduced now in all the lists and papers concerning the revision of Estonian lichens (see also Jüriado, 1998; Lõhmus, 1998; Suija, 1998). In the present treatment doubtful species are not included in the red list. 2. Five new species have been found during the last few years: Bryoria furcellata (Fr.) Brodo & D. Hawksw. (Randlane et al., 1997; ICEB, dup. in TU), Dermatocarpon luridum (With.) J.R. Laundon (TU), Phaeophyscia chloantha (Ach.) Moberg (Moberg, 1997; UPS, dup. in TU), Ramalina elegans (Bagl. & Carestia) Jatta (Skytén, 1993; H), Solorina bispora Nyl. (Moberg, 1997; UPS). One more species – Ramalina capitata (Ach.) Nyl. – must be added to the list, according to earlier literature data (Räsänen, 1931), as doubtful. 76 Folia Cryptog. Estonica 3. One species – Usnea glauca Mot. – is excluded from the list after re-determination (det. Pekka Halonen 1997 as U. scabrata). 4. Some species reported as extinct in Trass & Randlane (1994) have recently been found again: Alectoria sarmentosa (Ach.) Ach. (Martin & Martin, 1998; ICEB, dup. in TU), Cladonia brevis (Sandst.) Sandst. (TU), Leptogium gelatinosum (With.) J.R. Laundon (TU), Melanelia hepatizon (Ach.) A. Thell (Randlane et al. 1997; ICEB, IE, dup. in TU). Thus, these taxa are present in our contemporary lichen flora. 5. Three more species – Nephroma helveticum Ach., Punctelia subrudecta (Nyl.) Krog and Umbilicaria hyperborea (Ach.) Hoffm. – should be considered as extinct from Estonia, according to the latest data. RED LIST OF ESTONIAN MACROLICHENS The following threat categories have been applied: 0 – extinct or probably extinct, 1 – endangered, 2 – vulnerable, 3 – rare, 4 – care demanding, 5 – indeterminate. Criteria for including the species and numeral data are presented in discussion. In nomenclature Trass & Randlane (1994) are mainly followed; changes in taxonomy or nomenclature compared to this are pointed out in brackets. ALECTORIA SARMENTOSA (Ach.)

Poelt 3 DISCUSSION The present red list of macrolichens was compiled as a part of a larger project “Red Data Book of Estonia. Threatened Fungi, Plants and Animals” (Lilleleht, in press) which hopefully will be published in 1998. Threat categories applied in this project were discussed on several meetings of the Nature Conservation Commission of the Estonian Academy of Sciences, consisting of representatives of different specialities. As a result, the desision was made to apply the categories that were already in use in the Red Data Books of neighbouring countries (Andrušaitis, 1996; Aronsson et al., 1995; Ingeloeg et al., 1993; Rassi et al., 1992), with minor changes. This is the first officially recognised red list of Estonian lichens (available also in internet http://www.ut.ee/lichens/red_list.html), although some earlier publications also present relevant information: the list of 93 Estonian lichens in need of protection (Trass & Randlane, 1986) and the list of 38 extinct macrolichens in Estonia (Trass & Randlane, 1987). A list of 40 macrolichen species that should be enclosed in the Red Data Book of Estonia was printed in an encyclopaedic reference book a few years ago (Eesti A ja O, 1993). The new list, based on latest verified data, includes 110 species, which comprises 33% of the total macrolichen flora known in Estonia at present. The distribution of taxa between the threat categories and the criteria for their including are as follows. Category 0 – extinct or probably extinct – includes 18 species (16 % of the total number of lichens in the red list). Herbarium material verifies earlier occurrence of all these species in Estonia; in addition, there are no new records 78 Folia Cryptog. Estonica since 1950. Several taxa of this category (e. g. Hyperphyscia adglutinata, Nephroma helveticum, Umbilicaria hyperborea) have been collected from the present territory of Tallinn (Nõmme, Rahumäe, Kopli, Lasnamäe) at the end of the last or at the beginning of this century. These habitats and localities have been certainly destroyed by now. Some species have earlier also been found in other towns (Phaeophyscia chloantha from Kunda – a small but heavily polluted town in norteastern Estonia; Cetrelia olivetorum and Flavoparmelia caperata from the closest vicinity of Tartu). A few extinct species are recorded from the islands of Saaremaa (Kuressaare, Orissaare, peninsula of Sõrve), Abruka (Heterodermia speciosa) or Muhu (Toninia lobulata). Category 1 – endangered – includes 5 species (5 %). All these species are very rare in Estonia (found only once after 1950) and seriously threatened to a certain extent. Leptogium rivulare is a rare species in the whole world, confined to the periodically inundated trees or occasionally rocks, on the banks of sluggish rivers and ponds in northern Europe and northeastern USA and Canada. It has disappeared from several localities in Sweden, Finland and Russia as well as in France, Canada and USA (Jørgensen & James, 1983; Jørgensen, 1994; Sierk, 1964). Only a few current localities are known, one of them in Estonia: Pärnumaa Co., Lihula, river Kasari, leg. H. Trass 1957, det. T. Randlane 1986, verified G. Degelius 1991 (Randlane, 1987). This is a lichen that strongly depends on changes of water level and is threatened by the destruction of such habitats. Sphaerophorus globosus is an arctic-alpine lichen growing in Estonia on its southern limit, inhabiting here open localities – alvars – on the Saaremaa Island. The general threat to alvars – becoming overgrown with bushes and trees as a result of ceased grazing – is dangerous to several rare lichens of that habitat, including S. globosus. Lobaria scrobiculata, Nephroma bellum and Usnea glabrata grow in old virgin forests and are mainly endangered by forestry. Category 2 – vulnerable – includes 24 species (22 %). Lichens belonging to this category are either quite rare or sparsely distributed in Estonia but certainly sensitive to the environmental changes and, therefore, they may fall into the previous category in the future. The major threats are various: destruction of very specialised habitats (Cladonia parasitica, Pannaria pezizoides), vulnerability due to growth on the very limit of distribution area (Flavocetraria cucullata), air pollution and cutting of forests (Alectoria sarmentosa, Evernia divaricata, Ramalina calicaris). Category 3 – rare – includes 41 species (37 %). All macrolichens that are recorded from one or two localities only (and which are not included in the first three categories) are treated as rare. The main threats are not identified, the taxa are considered endangered by the occasional destruction of localities. Category 4 – care demanding – includes 21 species (19 %). These taxa are distributed sparsely or even widely in Estonia but they are evidently sensitive to various factors and their decline has been observed during last decades. Category 5 – indeterminate – comprises 1 species (1 %) at present (Ramalina elegans). The distribution of this taxon in North Europe was described only recently (Skytén, 1993); its general distribution area and precise ecological demands are not clear yet. The most important sites of endangered lichens in Estonia are: alvar communities, deciduous forests and wooded meadows, sandy dunes, calcareous or granite rocks (often on the seashore). Maintaining and undisturbing these habitats is the main strategy in protection of endangered lichens. ACKNOWLEDGEMENTS This research is a part of the project that was ordered and financed by the Ministry of Environment and the Foundation of Environment. The author is especially grateful to Hans Trass for the information and prolonged consultations during the last decades. All lichenologists in Tartu and Tallinn are thanked for discussions on the subject. Jan-Eric Mattsson is acknowledged for kindly revising the manuscript. REFERENCES Andrušaitis, G. (ed). 1996.

INTRODUCTION A thorough review revealing the present state of all herbaria of higher plants in Estonia (including private herbaria and collections of local museums and nature reserves) has been recently presented by Kukk (1997). Lichenological collections are much less popular and kept mainly in the research institutes. There are five intitutions in Estonia where scientific lichen herbaria are kept: International Center for Environmental Biology (ICEB), Institute of Ecology (IE), State Nature Museum (TAL), Tallinn Botanic Garden (TBA) – all four located in Tallinn – and University of Tartu (TU). Private lichenological collections are unusual in Estonia. The greatest private lichenological herbarium, founded in 1930s, belonged to Heinrich Aasamaa, a former lecturer of the University of Tartu. The conditions of these materials were unknown for decades. A few years ago it became evident that the collections, left in a farm near Tartu in the 1950s, had been destroyed. Heinrich Aasamaa, being over 80, started collecting lichens and preparing a herbarium again. All his present collections (including herbarium of higher plants of about 30 000 sheets) are kept at his home in Lasnamäe, Tallinn. Lichenological herbarium of the Institute of Botany and Ecology, University of Tartu (TU) is the oldest and biggest of all those listed above. The different collections of this herbarium, and the curative work in TU are shortly characterized in the present paper. RESULTS AND DISCUSSION Lichenological collections in TU include about 62 000 specimens. There are three main sections: Estonian herbarium – ca. 24 000 specimens Geographical collections – ca. 30 000 specimens Comparison herbarium (incl. exciccatae) – ca. 8 000 specimens. All materials are arranged in the alphabetical order of genera – inside each section – and in the alphabetical order of species – inside the genera. The Estonian herbarium of TU is the biggest collection of Estonian lichens in the world (about 24 000 specimens). Smaller collections of Estonian lichens are kept in other local herbaria as well – ICEB, IE, TAL, TBA – and to a lesser extent also in H, LD, RIG, S and UPS. Managing of Estonian herbarium has been our priority task during last four years. It has been re-arranged recently according to the modern taxonomy (accepting small genera of parmelioid, cetrarioid, lecideoid etc. lichens) in the course of verifying 82 Folia Cryptog. Estonica all specimens to compile the new checklist of Estonian lichens. Specimen databasing has been started using the computer program BRAHMS (Botanical Research And Herbarium Management System). The system was initially worked out by Denis Filer , Oxford Forestry Institute. Versions 3.3 and 3.4 have been applied for managing lichenological herbarium in TU. A module known as RDE (Rapid Data Entry), linked to BRAHMS, has been used to enter various information connected with the herbarium specimens. Configuration of RDE files has been edited according to our special needs of lichenological herbarium. Every file includes data about specimens of one species. Characters stored are the following for every specimen: collector and field number, number of the specimen in herbarium, additional collectors, genus, species, author(s), infraspecific taxa, date of collection, geographical locality, ecological group (based on substratum), longitude, latitude and altitude of the site of collection, local grid, herbarium name where the collection and its duplicates are kept, determiner and the date of identification, presence of fruiting bodies and parasymbionts, vitality, other ecological data, data of chemical and anatomical studies, other notes by the determiner (Saag, 1996). After importing all these data into BRAHMS, general specimen cataloguing, production of different categories of labels, citation lists of specimens, floristic checklists and other research proceedings become possible. Mapping program DMAP (Morton, 1997)has been used together with BRAHMS to produce distribution maps. At the moment, data of about 5000 lichen specimens of Estonia (materials of all species from genera Acarospora, Adelolecia, Amandinea, Amygdalaria, Biatora, Buellia, Calicium, Carbonea, Cecidonia, Chaenotheca, Chaenothecopsis, Cyphelium, Diplotomma, Farnoldia, Fuscidea, Graphis, Ionaspis, Lecanora, Lecidea, Lecidella, Microcalicium, Mycocalicium, Miriquidica, Phaeocalicium, Placynthiella, Polysporina, Porpidia, Protoparmelia, Psilolechia, Pyrrhospora, Rimularia, Sagiolechia, Sarcogyne, Schaereria, Sclerophora, Sphaerophorus, Stenocybe, Tephromela, Thelomma, Trapelia, Trapeliopsis, Tremolecia, Rinodina) have been entered into RDE and imported into BRAHMS. The majority of data have been entered into the database by Inga Jüriado, Piret Lõhmus, Mari Sarv and Ave Suija; the technical managing of the Estonian herbarium has mainly been carried out by Inga Jüriado. The oldest lichen specimens in the Estonian herbarium date from the end of the last century. They were collected by Andreas Bruttan, altogether about 260 species, from Abruka, Aegviidu, Haaslava, Hiiumaa, Muhu, Saaremaa, Selja (Lääne-Virumaa), Tallinn, Tartu, Valga, Virtsu, Viru-Nigula. Part of his herbarium (179 sheets, with several species on each sheet, collected from the present territories of both Latvia and Estonia) are kept in RIG (Piterans, 1996). Other older collections of Estonian lichens in TU were raised by Paul Wasmuth (about 200 species), and by Konstantin Mereschkowski (only a few specimens preserved). Both persons worked during the first two decades of this century in Tallinn and its vicinity. Numerous materials (about 170 species) collected from Estonia (Abruka, Keila, Kunda, Lihula, Rakvere, Paldiski, Pärnu, Saaremaa, Tallinn, Tartu, Viljandi, Vilsandi, Väike-Maarja) by Veli Räsänen in 1927 and 1929, as well as some specimens collected by L. Kari, K. Linkola and E. Häyrén, are kept partly in TU and partly in H. Smaller collections of Hilja Lippmaa, Voldemar Reinthal, Jaak Ruubel, Gustav Vilbaste, that date mainly from the 1930s, are also deposited in this section. In the post-war period the biggest lichen collections have been raised by Hans Trass. Geographical collections raised by the coworkers of our institute (altogether about 30 000 specimens) are arranged into some bigger geographical units: I Extra-europian countries (mainly materials from Canada) II Europian countries 1. Foreign countries (mainly materials from Finland and Sweden) 2.

Field works in the vicinity of the Lake Baical (Khamar-Daban Mountain Range in the Irkutsk Territory and Buryatian Autonomic Republic) were carried out in 1979–1982 by a group of students and reseachers (A. Pärn, K. Zobel, A. Roosma, T. Randlane etc.) led by Hans Trass. More than 1000 sample quadrats were analysed using air pollution monitoring methods and about 10 000 specimens were collected. This is the biggest geographical collection of lichens in TU. Herbarium of lichens from the Russian Far East consists of ca. 8 500 specimens, collected from the Chabarovsk and Primorje Territories, Peninsulas of Kamtchatka and Tshukotka, Wrangel Island – by H.

INTRODUCTION The value of lichens as monitors of air pollution is undisputed and has captured the attention not only of lichenologists but also of biological and environmental scientists in general, as reflected by the endless flood of publications on this topic. This paper provides an historical review of the methodologies developed, and the different circumtances in which they have been employed, in order to monitor quantitative and qualitative changes in the British isles. Although several early British botanists noted that lichens did not thrieve in polluted atmospheres (e.g. Borrer c. 1812 in Turner & Borrer, 1839; Grindon, 1859; Macmillan, 1861), it was the famous Finnish lichenologist William Nylander, at that time working in Paris, who suggested that lichens might be used as indicators of air quality: his studies in the Jardin du Luxembourg showed first the decline in (Nylander, 1866) and later the disapperance of (Nylander, 1896) its epiphytic flora. More than 90 years were to elapse before epiphytic lichens returned to the Jardin du Luxembourg (Seaward & Letrouit-Galinou, 1991). British air pollution studies involving lichens in the second half of the 19th century and the first half of the 20th century, with few exceptions, were mainly concerned with casual observations on the impoversihment of urban floras or on the general decline in species over local areas (reviewed in Seaward, 1993). Such studies were instrumental in establishing baseline data which could be used later in time-space analyses. Hawksworth et al. (1973), for example, incorporated species data of earlier fieldwork in their reconstruction of the change in air quality in Epping Forest, near London, over the period 1784–1970; based on the nature and diversity of the epiphytic flora, and employing the scale devised by Hawksworth and Rose (1970), mean winter sulphur dioxide levels increased from less than 30 to 70–125 µg/m3 over that time. Further studies by Hawksworth and McManus (1992) have shown a remarkable recovery of this flora consequent upon environmental amelioration. As well as their value in time-space analyses, such distribution studies made it possible for the first time to compare the severity, extent and pattern of air pollution between cities (Hawksworth, 1971, 1973; Laundon, 1973). 86 Folia Cryptog. Estonica Several highly influential papers appeared in the 1950s which were to provide a springboard for the future development of lichen – air pollution studies. The first of these, by Jones (1952), contained details of lichen floras of tree boles at sites in England where air pollution levels were known. This made it possible for the first time to construct pollution monitoring scales based on the composition of the lichen flora. Based upon this rudimentary scale, many more sophisticated bioindicational scales were developed. Prior to this period, an ‘air pollution hypothesis’ had evolved to explain the paucity of lichens in urban areas and the gradual decline in the European lichen flora generally since the Industrial Revolution at the end of the 18th century. However, the constituents of air pollution responsible for these phenomena had not yet been determined; indeed, Jones (1952) and others had indicated smoke and/or soot deposition to be the main cause. Today, sulphur dioxide is recognized as being the major culprit affecting lichen vigour. However, other air pollutants are often implicated, and ever-changing environments, the exacerbatory/synergistic/buffering effects of two or more constituents of a complex pollution burden also affect lichen performance. It was two publications in 1958 by the Dutch and Swedish scientists Barkman and Skye respectively which most influenced future research on lichens and air pollution in Britain and elsewhere. Since most field studies on this subject relied on the morphological nature and ecological performance of epiphytic lichens, Barkman’s (1958) monumental treatise on the phytosociology and ecology proved of immense value in establishing protocols for description and measurement. Skye (1958) recognized sulphur dioxide to be the overriding factor affecting the lichen flora around an oil-shale works. This and his detailed investigation of the compostion and distribution of lichens in and around Stockholm (Skye 1968) provided models for a very large number of subsequent investigations. Casual observations of differences in the composition and numbers of species between lichen floras in polluted and unpolluted areas in earlier studies had been replaced by a simplistic zonal interpretation based on the concept of ‘desert’, ‘struggle’ and ‘normal’ devised by Sernander (1926), to be superseded in its turn, largely as a consequence of Skye’s work, by more detailed zonal studies in the 1960s. Investigations in Britain at that time were centred on individual industrial plants, towns or cities, or on urban/ industrial complexes, but regional and national studies were to follow with the establishment of the British Lichen Society’s Distribution Maps Scheme which commenced in September 1963 (Hawksworth & Seaward, 1990); by applying Sernander’s concept of ‘desert’ to these maps it has been possible to rank species susceptibility to air pollution (see below). The key paper on zonal mapping was by Hawksworth and Rose (1970) who devised a qualitative scale using epiphytic lichens for the estimation of sulphur dioxide air pollution. Their scheme, designed for use in England and Wales, is based on simple phytosociological analyses which delineate zones equated with mean winter sulphur dioxide levels. This scale has stood the test of time, proving of immense value in air pollution monitoring throughout the British Isles, as well as forming the basis, often only requiring minor adaptation, for scales in Europe and elsewhere. It has been extensively used to monitor the extent or spread of air pollution, particulary sulphur dioxide; however, in areas experiencing reduced levels of, or qualitative changes in, pollution as a result of clean air legislation, it may be less effective (Seaward, 1987; Van Haluwyn & Lerond, 1988; Richardson, 1988). It should be noted that its biological scale is logarithmic in nature (Seaward, 1993, 1997): although major reductions in the sulphur dioxide level at the polluted end of the scale may have little or no effect on lichen species diversity, moving from a polluted to a less polluted situation exponentially increases the effect on the lichen vegetation, so that even a minor increase in sulphur dioxide would dramatically reduce species diversity. The establishment of baseline data from zonal studies and transect work employing strict methodological protocols, regulary updated to provide valid data, is highly effective in timespace analyses aimed at demonstrating environmental changes, for good or ill, or in predictive interpretation through modelling (HendersonSellers & Seaward, 1979; Seaward, 1997). 87 AMELIORATING ENVIRONMENTS The undoubted improvement in the lichen flora in many parts of the British Isles during recent years has been clearly demonstrated (Henderson-Sellers & Seaward, 1979; Seaward, 1980, 1993, 1997; Bates & Farmer, 1992; Rose & Hawksworth, 1981; Hawksworth & McManus, 1989). However, it is evident from the above works that the nature of a re-establishing lichen flora differs from that formerly wiped out by air pollution. From our knowledge of the behaviour of lichens subjected to sulphur dioxide air pollution, it has been possible to rank species according to their sensitivity to this pollutant, but variations in replacement assemblages will necessitate modifications to some bioindicational scales to account for these hierarchical changes. The distribution of Usnea spp. in the British Isles illustrates the type of change which has occured since about 1800. This genus, at one time widespread and luxuriant, had over the course of the next 160 or more years almost entirely disappeared from a major area of England and Table 1.

Estonica Wales covering at least 68,000 km2 (Fig. 1), and at least 6,000 km2 of lowland Scotland, mainly as a result of the increase in atmospheric pollution. However, since the implementation of the Clean Air Acts of 1956 and 1968 in Britain, sulphur dioxide concentrations have declined dramatically in urban/industrial areas, with less dramatic reductions, or indeed occasional rises due to changes in pollutant dispersion techniques, in rural areas, so that much of Britain is now experiencing a more homogeneous distribution of this pollutant. The re-establishment of Usnea spp. (mainly U. subfloridana), ususally on Fraxinus and Salix, at numerous sites throughout the British Isles during recent years may largely reflect decreases in pollution levels. There is some evidence that Ramalina farinacea, Evernia prunastri and Bryoria fuscescens are exhibiting a similar response. It would appear, however, that the stability of these taxa of these sites is tenuous, since small thalli may only succeed in establishing themselves for one or two years. Nevertheless, it is now proving possible to monitor ameliorating environments on a relatively large scale through the use of lichen mapping (Fig. 1). Table 1 has been assembled from detailed comparative studies of the distributions of selected lichen species within a prescribed region of 128,700 km 2 (Fig. 2): comparisons have been made between (a) field data derived from the British Lichen Society’s Mapping Scheme up to May 1980, some of which were used in the preparation of the first volume of the Lichen Atlas (Seaward & Hitch, 1982) and (b) that derived from the current (November 1997) database to demonstrate the large-scale monitoring capabilities of lichens. These data show the strong correlation between a lichen’s sensitivity to air pollution (mainly sulphur dioxide) and the area from which it had declined, as can be seen from the distributions of, for example, Ramalina farinacea (Fig. 3), Usnea spp. (Fig. 1) and Parmelia perlata (Fig. 4), their ‘deserts’ in c. 1970 extending over 45,000, 68,000 and 88,000 km2 respectively. However, it is also clear that rankings (cf. Seaward, 1992, Table 1) are changing due to the different abilities of species to re-establish themselves in areas experiencing atmospheric ameloration. Hence, since the previous analysis undertaken less than five years ago, some species, Lecanora expallens, Parmelia subaurifera, Evernia prunastri, etc. (see Table 2) have a greater capacity to adapt to these new regimes. Regional or ‘blanket’ pollution over wide areas has reduced lichen diversity, but has favoured expansion of a relatively small number of species formerly having narrower ecological requirements and more restricted distributions, such as Parmeliopsis ambigua (Fig. 5), Scoliciosporum chlorococcum (Fig. 6) and Xanthoria polycarpa (Fig. 7). Some species which are moderately tolerant of sulphur dioxide air pollution have been able to spread in areas where other species have been eliminated. Parmelia laciniatula and P. elegantula, first recorded in the British Isles as recently as 1933 and 1965 respectively, are two such species and detailed distributional studies show them to be on the increase due to both quantitative and qualitative changes in air pollution (Seaward, 1993). ‘Acid rain’ can affect lichens both directly or indirectly through the acidification of substrata. Parmeliopsis ambigua (Fig. 5), for example, which was formerly to be found mainly on decorticate conifer wood in Scotland, has, over the past few decades, undergone a remarkable expansion onto deciduous trees in moderately polluted areas throughout Britain (cf. Seaward, 1992, 1993), in response to increased bark acidification. The development of more oligotrophic epiphytic lichen floras, including such species as Micarea nitschkeana (Fig. 8), has been reported in the British Isles as a result of changes in the nature of pollutant emissions, but their present distribution is poorly understood; since many of the microlichens in these floras are difficult to determine, particulary in the field, their use as monitors of ‘acid rain’ will be limited. Furthermore, deposition of nitrates via acid rain, emanating from NOx emissions, can produce a fertilization effect (see below), as yet little studied, which encourages numerous lichen species to flourish, at least over the short term. Changes in the present lichen composition in many areas of the British Isles are often as much a reflection of increased eutrophication as a reduction in sulphur dioxide levels. Numerous species which are now spreading into suburbs are equally successful elsewhere but formerly had narrower ecological requirements and more restricted distributions. They are probably fa- Fig. 1.

A fertilization effect on the lichen flora may manifest itself as a consequence of a reduction in the sulphur dioxide burden, but there are instances where this effect generated from factory emissions may ameliorate a local sulphur dioxide problem (Seaward, 1990). The recent spread of some species into city suburbs and elsewhere may be promoted by windborne nutrient-enriched dusts (Seaward, 1997). By 1973, Ramalina farinacea had disappeared from c. 47,300 km2 of England (Fig. 3), an area incorporating 457 of the 10 km × 10 km recording units (Seaward, 1992); since then, this taxon has been recorded from 78 of these units, showing its successful re-colonization not only of sites formerly experiencing sulphur dioxide levels of 60 µm/m3 or more, but also those where barks of trees and shrubs have become moderately nutrient-enriched. The increasing occurrence of Xanthoria polycarpa throughout the British Isles (Fig. 9), where mean winter sulphur dioxide levels have fallen below 60 µg/m3, is due in no small measure to agrochemicals which have promoted its growth even in the inner suburbs of most large towns and cities (Seaward, 1997). In 1980, it had been recorded from 580 recording units, and by 1991, it occurred in 869 (Seaward, 1992); in June 1993, this figure has risen to 966 (Seaward, 1993) and by November 1997 had reached 1249. From an ever-present rich air spora, only a few species are capable of surviving the crucial stages of establishment, germination and development in polluted environments. Once established, such toxitolerant species are strongly competitive, with a high reproductive capacity and a tenacious hold on the substrata they colonize; they can create monovegetational cover, even when a reduction in air pollution level would presuppose reinvasion by formerly successful species. This is illustrated by the rise to dominance of Lecanora conizaoides throughout the British Isles, and much of Europe, over the past half century. It was first recorded in Britain in about 1860, since when its spread has been dramatic: by 1953, it occupied c. 121,800 km2; by 1973, it occupied c. 185,300 km2, and by 1997 this had extended to c. 207,900 km2 Fig. 7.

Estonica (Fig. 10). Air polluted environments provide an ideal milieu for the spread of this taxon, and even amelioration, resulting from the implementation of clean air policies, has not as yet broken its monopoly of substrata. CONCLUDING REMARKS Profitable lines of enquiry into determining the effects on lichens of the new air pollution regimes should include long-term field techniques involving stringent ecological and phytogeographical criteria. To a large extent, such studies have been made possible in the British Isles through a comprehensive ongoing programme of detailed lichen mapping carried out by members of the British Lichen Society since 1963. Although detailed lichen atlases (eg. Seaward & Hitch, 1982; Seaward, 1995 onwards) contribute significantly to the documentation of atmospheric regimes, mapping programmes must be supported by extensive field studies in a wide range of selected habitats in critical areas where more immediate changes can be scientifically diagnosed by means of bioindicational techniques complemented by adequate monitoring equipment. Intensive lichen monitoring is a necessary component of any programme aimed at effective long-term observation of air pollution. There is a wealth of evidence to demonstrate the selective decline of lichen species over much wider areas during the past two centuries, mainly attributable to the rise in sulphur dioxide levels, although other pollutants and changing forestry and agricultural practices are also implicated. Lichen mapping is often a race against time, particulary in those areas where clean air legislation and changes in energy policies and industrial practices have been implemented: both qualitative changes in, and dramatic reductions in the level of, air pollution are reflected in the consequent reinvasion by lichens. At the same time, a less dramatic, but nevertheless significant, rise in pollution level over wide geographical areas due to changes in pollutant dispersion techniques has resulted in the loss of a number of lichen species, although others have been able to exploit/tolerate the new atmospheric regimes. Lichens have been used as monitors of environmental conditions for many years. How- ever, any successful use of lichen bioindicators must depend upon the rigorous definition of the monitoring scales adopted and a complete analysis of all the environmental parameters which affect their propagation, establishment and subsequent growth. The use of bioindicators has the obvious advantage of permitting long-term monitoring without widespread establishment and maintenance of costly and sophisticated equipment. Unfortunately, most of the existing bioindication scales rely on species diversity counts, or at least on a fairly detailed understanding of taxonomy, thereby making the techniques as difficult to employ as sophisticated measuring equipment. It is therefore a serious cause for concern that taxonomic skills are no longer considered an essential component of many biological educational programmes in Britain and elsewhere. Physical and/or chemical surveys do not necessarily measure those air pollutants which are harmful to biological materials. On-site measuring devices are limited both in number and scope; furthermore, they are unevenly spread over a country, usually being concentrated in urban and industrial complexes (Seaward, 1993). Not only the implementation of a clean air policy resulted in widespread ‘blanket pollution’, but the location of industry and power stations away from cities has also added to the atmospheric burden over wide areas. The use of corroborative information derived from bioindication surveys to support the limited data available from rural sites is strongly recommended. It will never be completely possible to replace direct physical and chemical measurements of air pollutant concentrations by the use of bioindicators; nevertheless, both approaches are necessary for making detailed or large-scale surveys of the distribution of air pollutants, where the extensive use of technical equipment is costly or impractical. DEDICATION This paper is respectfully dedicated to Professor Hans Trass whose extensive ecological and phytogeographical studies of the Estonian lichen flora have made it possible to exploit fully their potential to monitor his country’s environment.

Currently there are about 112 moss and 14 liverwort species that are common to both Australia and northern Europe, i.e. 10% and 3% respectively of the relevant Austalian floras. The majority of these species are restricted to Southeast Australia (including Tasmania). Of the 126 species compared 8 (2 liverwort) are cosmopolitan species, and 13 (1 liverwort) species may possibly be so; 12 species (all mosses) are recent introductions by man to Australia, and a further 9 are considered as possible introductions; 72 (6 liverwort) species are considered as bipolar disjunctive, including the recently confirmed Scorpidium scorpioides. Comments are also included on the Australian distribution and habitat preferences for many of these species. Kokkuvõte: H. Streimann. Austraalia ja Põhja-Euroopa brüofloorade võrdlus.

INTRODUCTION Very few studies have been undertaken to compare the bryophytes of the southern hemisphere to other regions of the world, mainly because of the lack of bryological information from the Australian region. Schofield investigated the bipolar mosses in the southern hemisphere, especially New Zealand (1974), while Piippo & Koponen (1997) investigated the affinities of the western Melanesian moss flora to Australia. The affinities of Asiatic and Australian liverwort floras were investigated by Piippo (1992). This investigation was primarily initiated by numerous queries in discussions with northern European and Australian bryologists who were interested in the similarities of the bryoflora between the two regions. This work compares the similarities in the bryophyte floras of Australia and northern Europe, especially Scandinavia and northern European Russia (Fig. 1). Northern European Russia comprises the regions of European Arctic, Northwest and Northeast Russia and northern Ural Mountains (Ignatov & Afonina, 1992). Many of these similarities no doubt will apply also to other northern regions. Many people, including plant botanists, are not aware of how widespread many cryptogams found in Australia are and they are surprised to learn that Australia shares many species with colder northern regions. The bryophyte relationships of tropical Australia with Southeast Asia, and temperate Victoria and Tasmania. with the Nothofagus forests of South America are easier to understand than relationships to the colder northern hemisphere. The vegetation and climate differences between these two geographically distant areas are considerable. Although Australia has warm to hot arid to semi-arid regions, snow is a regular feature for part of the year in the sub-alpine regions of New South Wales, Victoria and Tasmania. Sub-alpine in this work refers to the shrub and herb dominated areas above the tree line. The Australian vascular flora has adapted to the climatic extremes and generally poor soils which resulted in a distinctive vegetation. While vascular plant geographic distribution does not extend far from Australia, endemic species comprise 85% of the flora (Anon., 1996). Distribution of the moss flora is more widespread with only 98 Folia Cryptog. Estonica Fig. 1. Territories of compared bryophyte floras in northern Europe and Australia. 99 about 38 % endemism (Streimann & Curnow, 1989, with subsequent unpublished amendments due to revisions). Vascular plant species diversity is greatest in Queensland (Hnatiuk, 1990) because of its Nothofagus, tropical to sub-tropical forests, monsoon scrub, arid western regions and the higher peaks which have a distinctive flora. However, New South Wales has the richest recorded bryophyte diversity because it also has sub-alpine vegetation and Lord Howe Island in the Pacific Ocean. Bryophyte studies in Australia lag far behind those of the vascular flora. Exploration, though woefully inadequate, still reveals species previously unreported from Australia. Revisions will possibly decrease the number of endemic species, especially from tropical Australia as many of those species may prove to be geographical variations of widespread Southeast Asian species. The number of bryophyte species may remain stable or decrease. Some names may still be mis-applied in Australia e.g. Bryoerythrophyllum recurvirostre, Pohlia bulbifera, while some large groups e.g. Bryum, Pottiaceae and Sphagnum are still inadequately understood in Australia. Because of our limited knowledge of Australian (except possibly Tasmanian) cryptogams, the diversity and, geographic relationships have not been investigated fully. This study is based mainly on data from Damsholt et al. (1969), Frisvoll et al. 1995, Hallingbäck & Söderström (1987), Ignatov & Afonina (1992), Ingerpuu et al. (1994), Jóhannsson (1983), Kannukene et al. (1997), Konstantinova et al. (1992), Koponen et al. (1977), Nyholm (1986, 1989, 1993) for northern Europe. For Australia Scott & Bradshaw (1986) and Streimann & Curnow (1989) were used. All Australian species of doubtful occurrence were ignored. It must be borne in mind that the analyses of Australian bryophytes, and especially liverworts, are incomplete as most old collections lack adequate data and some recent collectors do not record habit and habitat data. Also many species and areas are still under collected and therefore their range, habitat preferences and distribution are not known with certainty. Bryophyte numbers for the countries in this study are given in Table 1. The number of Australian moss species in common with the various European countries studied is much greater than was expected, but still represents only a small component of the Australian moss flora. However, when the number of species common with individual northern European countries or regions are compared they comprise 14–21% of moss flora and only 5–9% of the liverwort flora (Table 2).

BIOGEOGRAPHICAL COMPARISONS OF MOSSES The moss species common to Australia and northern Europe that have been analysed include cosmopolitan, disjunctive bipolar and introduced species. For these species, and the majority of the remaining species, comments are made on their Australian range and habitat preferences. Cosmopolitan mosses Such species generally thrive in disturbed or open areas and many follow man and his habitation. They are mostly hardy species. It is nearly impossible to ascertain if they were introduced prior to European settlement of Australia. Often there are various interpretations as to what constitutes a cosmopolitan species and an introduced species. Species can be spread unintentionally by birds, animals and man, and this can be considered as a natural function of plant migration. Species in Australia considered as cosmopolitan are: Bryum argenteum, B. caespiticum, B. capillare, Funaria hygrometrica, Leptobryum pyriforme, Polytrichum juniperinum. Other species that may fit into this category are: Amblystegium serpens, Aulacomnion palustre, Brachythecium plumosum, Bryum dichotomum, Ceratodon purpureus, Grimmia laevigata, G. pulvinata, Polytrichum commune, Schistidium apocarpum, Tortula muralis, T. papillosa which is generally found in abundance on exotic trees and Weissia controversa. Introduced species Schofield (1974) lists 14 moss species introduced by man to New Zealand, the majority of which also occur in Australia. There are 9 species in Australia that are bipolar as well as introductions and they are generally considered in this section. The following 12 species are considered native to the northern hemisphere, but introduced to Australia: Barbula unguiculata, Brachythecium albicans, B. mildeanum, Bryum radiculosum, B. rubens, Calliergonella cuspidata, Phascum cuspidatum, Pottia truncata, Pseudoscleropodium purum, Pterygoneurum ovatum, Rhytidiadelphus triquetrus, Tortula laevipila. Catcheside (1980) suggests that the following species may have also been introduced to Australia: Acaulon mediterraneum, Aloina rigida, Amblystegium serpens, Barbula hornschuchiana, Brachythecium rutabulum, Kindbergia praelonga, Physcomitrium pyriforme, Pottia davalliana, Pottia starckeana. These introductions can be assumed to be the result of European settlement in Australia as the majority of collections were found in anthropogenic habitats or near to them. Further field studies are required to resolve their status. Rhytidiadelphus triquetrus is a recent introduction to Australia and New Zealand (Dalton, 1997). It is extremely common in the wet, western Tasmania. This species aggressively invades lawns (especially golf courses), exposed waste land and roadsides where grass cutting apparently assists in dispersal. Two Australasian species have taken the reverse track and have found the European environment suitable and reached the southern part of the study area. They are Campylopus introflexus (Denmark, Sweden, Norway) and Orthodontium lineare (Denmark, Sweden). Bipolar disjunctive mosses Du Rietz (1940) defined these taxa as “distributed both in the boreal and austral zone but absent from the tropical lowlands, with or without 101 intermediate populations in tropical mountain areas”. This definition was used by Schofield (1974) and has been followed here. Schofield & Crum (1972) discussed disjunction in bryophytes and commented comprehensively on the various explanations that were offered for this distribution pattern. They mentioned only two species relevant to Australia, Sanionia uncinata and Pseudoscleropodium purum, and provided distribution maps. Subsequently Schofield (1974) analysed the bipolar disjunctive mosses of New Zealand, but such studies have not been undertaken previously for Australian bryophytes. He included distribution maps for some species, of which Aulacomnium palustre, Ceratodon purpureus, Climacium dendroides, Desmatodon heimii, Orthodontium lineare, Pottia truncata, Sanionia uncinata and Ulota phyllantha are also found in Australia, but the latter not for New Zealand. Schofield (1974) listed Plagiothecium denticulatum (Hedw.) B.S.G., but most New Zealand and all Australian collections have proved to be P. novae-zealandiae Broth. (Ireland, 1992). Similarly Mnium rostratum Schrad. in Australasia proved to be Plagiomnium novae-zealandiae (Col.) T. Kop. (Koponen, 1981). New Zealand bipolar mosses numbered 83 species (Schofield, 1974), but for Australia the number is about 66, of which the following have not been reported for New Zealand: Bartramia halleriana, Bryum alpinum, B. creberrianum, Calliergon sarmentosum, Drepanocladus sendtneri, Meesia triquetra, Racomitrium heterostichum, R. sudeticum, Scorpidium scorpioides, Ulota phyllantha. An interesting distribution is that of Climacium dendroides which so far has been reported only from the Dargo High Plains in Victoria. It is not common there, but the two colonies found were in seepage areas and quite large. The only other southern hemisphere occurrence is in New Zealand. The recent discovery of Scorpidium scorpioides in Tasmania (Dalton et al., 1991) was unexpected as it does not occur in New Zealand. The species was common in continuous colonies around the perimeters of small, shallow alkaline ponds. It may prove to be more common than present reports suggest. It was not known from New Zealand when Schofield (1974) reported on the New Zealand bipolar mosses. Bartramia halleriana, Conostonum tetragonum, Polytrichastum alpinum are absent from Denmark and Estonia because they are mountain species. Bryum creberrimum, which prefers basic substrates is absent from Estonia. Pterygoneurum ovatum is absent from Estonia, Finland and Iceland. Bryum sauteri is present in Norway and Iceland only, while Grimmia laevigata is reported only from Sweden and Denmark. Species widespread in Australia Widespread species are predominantly in the families Bryaceae or Pottiaceae and occur in open or disturbed areas. They include: Aloina aloides var. ambigua, Barbula hornschuchiana, Bryum creberrimum, B. dichotomum, B. torquescens, Campylopus pyriformis, Grimmia pulvinata, Hedwigidium integrifolia, Pottia davalliana, Pterygoneurum ovatum, Tortula papillosa and Weissia controversa. Of them Grimmia pulvinata and Hedwigidium integrifolia prefer drier granitic rocks at medium altitudes, generally in woodlands. Physcomitrella patens occurs in moist areas of southern Australia and in northern Europe it occurs on mud or silt, but is absent from Iceland. Cold climate and high altitude species Australian regions where the climate would resemble that of northern Europe are the Australian Alps (New South Wales, Victoria), the highland areas of these two states plus Tasmania and Macquarie Island. Tasmania. Tasmania has a cooler and moister climate than most of mainland Australia. This is reflected in the high number of species restricted to that state only in Australia, but also common with New Zealand. Species known only from Tasmania and occurring in northern Europe are: Buxbaumia aphylla, Dicranella schreberiana, Fissidens adianthoides, Grimmia funalis, Kiaeria starkei, Polytrichum formosum, Racomitrium heterostichum, Rhytidiadelphus triquetrus, Scorpidium scorpidioides, Sphagnum compactum. Macquarie Island. Ulota phyllantha is the only species restricted to Macquarie Island where 102 Folia Cryptog. Estonica it forms compact cushions on rocks. It was reported (Seppelt, 1978) from a raised beach terrace and apparently it is salt tolerant. Southeast Australian species that extend to Macquarie Island are: Amblystegium serpens, Brachythecium rutabulum, B. salebrosum, Desmatodon heimii, Drepanocladus aduncus, Kindbergia praelonga, Orthodontium lineare, Sanionia uncinata, Schistidium apocarpum, . Widespread and common southern Australian species that are absent from humid tropical areas but extend to Macquarie Island are Campylopus introflexus, Ceratodon purpureus, Grimmia laevigata and Hypnum cupressiforme. This latter species is not common in Western Australia. Another common and widespread Australian species found on the Island is Polytrichum juniperinum. High altitude species. The highest proportion of species which also occur in northern Europe reach their best development in the Australian Highlands and the alps, mostly preferring the moister areas. McVean and Weber were the first to collect widely in the Kosciuszko National Park. J.H. Willis included mosses amongst his plant studies on the Bogong High Plains of Victoria. In my continuing studies in the High Plains of Victoria several species have been found that are more common than previously reported (e.g. Meesia triquetra reported as rare by Scott & Stone, 1976). In Tasmania many of these species would occur at lower altitudes. High altitude species that are confined to swampy or moist areas include: Brachythecium rivulare, Bryum algovicum, B. muhlenbeckii, B. pseudotriquetrum, B. subapiculatum, B. tenuisetum, Calliergon sarmentosum, Calliergonella cuspidata, Campylium polygamum, Climacium dendroides, Drepanocladus aduncus, D. sendtneri, Leptodictyum riparium, Meesia triquetra, Pohlia bulbifera, P. cruda, Sanionia uncinata, Scorpidium scorpioides, Warnstorfia exannulata, W. fluitans. Pohlia nutans and Pohlia wahlenbergii can also occur at mid-elevations where they can withstand slightly drier conditions. Mosses found predominantly on rocks or rock-faces include: Distichium capillaceum, Fissidens adianthoides, Grimmia trichophylla, Orthotrichum rupestre, Racomitrium heteros- tichum, R. sudeticum, Schistidium rivulare, Tortula ruralis. Racomitrium lanuginosum is common in northern Europe. In Australia it is represented by the ssp. pruinosum Wils. It is scattered and moderately common in the sub-alpine regions, but rarely forming large continuous colonies. Sanionia uncinata is found in moister areas on the bases of treelets and shrub stems, on logs and along water course banks. Other species Some species barely manage to reach the European study area, possibly because they prefer the milder climates. Two species are found only in southern Sweden where they are not very common – Acaulon mediterraneum and Pottia starckeana. Acaulon mediterraneum occurs on lawns and river flats while the latter species is possibly introduced to Australia (Catcheside, 1980), being common in southern Australia on disturbed soil and in urban habitats. Bryum torquescens is rare in Denmark and southern Sweden while reasonably common in Australia on coastal sand dunes. Pottia davalliana which occurs in disturbed situations in southern Australia is not common in northern Europe, especially Estonia. Aloina rigida is restricted to South Australia where it occurs on calcareous soils in dry disturbed habitats. Catcheside (1980) suspects that it may be introduced. In northern Europe it is found in Denmark, Estonia, Sweden and Norway, possibly in the warmer regions. An exclusively limestone moss in Australia, as in Europe, is Orthotrichum cupulatum which is restricted to mid-elevations in southeast Australia. Encalypta vulgaris occurs in drier southern Australia and is found on the ground, rocks and rock crevices, often also on limestone. Bryum alpinum is known from one Victorian mountain locality from rocks (type unknown) in a creek while in Europe it prefers wet acid rocks. B. dichotomum occurs on clayey or silty soils, rocks, moist and sheltered areas and on disturbed soils in towns. Hedwigia ciliata prefers drier acid rocks and is common at mid-elevations in paddocks and Eucalyptus woodlands, while in Europe it is found on rocks in paddocks. Several species that are found in both northern Europe and Australia occur in sub-tropical 103 Queensland. Didymodon vinealis and Trichostomum brachydontium, are found in the drier interior from southern Queensland to Western Australia. Anoectangium aestivum has been reported from eastern Victoria, Southeast New South Wales and from tropical coastal Queensland. Another species that reaches Queensland, and is reasonably common in moister Southeast Australia, is Neckera pennata. Campylopus flexuosus is restricted to northeast Queensland where it occurs above 760 m, but is more common on the higher mountains. COMPARISONS OF LIVERWORTS Fewer species (Table 1), and a smaller proportion of liverworts are common between the two study areas (Table 2). Of the 436 species found in Australia 26 genera extend into the northern European study area, with only 10 genera with 14 species common to the two regions. Cosmopolitan species are not common in Australia with only 2 species considered cosmopolitan. Lunularia cruciata is common along water courses, generally in disturbed, manmade habitats, but also in various vegetation types that often dry out. Ricciocarpus natans is common on still lakes, especially those with bird populations (Scott, 1985). Schuster (1992) considers Pallavicinia lyellii to be sub-cosmopolitan being confined to temperate regions. In Australia it occurs in moister forested areas at lower elevations in Tasmania and Victoria. Scott (1985) considered Marchantia polymorpha to be recently introduced, but CANB collections annotated by Bischler-Causse (1989) indicate that this species occurs in natural vegetation, as well as man made habitats between 600–1600 m in moister Southeast Australia. Six species can be considered to be bipolar disjunctive and are confined to Southeast Australia and Tasmania. Calopogeia sphagnicola is confined to Tasmania. Cephaloziella arctica is found in a wide range of vegetation types, generally on burnt logs or soil, between 80–1400 m. Lophocolea bidentata ranges from Eucalyptus forests to sub-alpine heath, from near sea-level to 1520 m, and extends to grasslands on Macquarie Island. Lophocolea minor prefers moist, often calcareous rocks, in temperate forest and on semi-exposed ground at low to mid-altitudes. Metzgeria furcata is found in various forest types and commonly on road cuttings between 20–1600 m, and extends to grasslands on Macquarie Island. Riccia sorocarpa prefers soil and rocks in drier areas at lower elevations. Two species are restricted to warmer, semi- to arid regions at lower altitudes. Riccia cavernosa occurs on clay or sand. Riccia bifurca is found generally in moister regions, often in towns while in northern Europe it occurs also at low to mid-altitudes. Diplophyllum obtusifolium is confined to the sub-alpine areas where it occurs on rock ledges. Metzgeria conjugata is found in New South Wales and Tasmania, but no further data were available.

INTRODUCTION MATERIALS AND METHODS Since the last and the most complete checklist of Estonian lichens (Trass, 1970) until now, many important changes in lichen systematics have been taken place. For example, the catalogue by Trass contained 45 species in the genus Lecidea, while only four of them belong to the genus today. All other species have been placed into 15 different genera. The term “lecideoid lichens” was proposed by H. Hertel (1984) to unite all taxa previously treated in the genus Lecidea. 53 lecideoid lichen species representing 20 genera plus eight species with uncertain position are listed in the present paper. 43 species occur in the contemporary lichen flora of Estonia; six (Amygdalaria panaeola, Adelolecia kolaensis, Fuscidea cyathoides, “Lecidea” hypopta, “L.” sphaerella, Trapelia coarctata) are considered to be extinct (records only from before 1950). Fuscidea lygaea, “Lecidea” albofuscescens, Lecidea sarcogynoides and Pyrrhospora cinnabarina have been included in the checklist because of information in old literature (Bruttan, 1870; Mereschkowski, 1913; Räsänen, 1931; Trass, 1970), whereas there are no herbarium specimens. Fuscidea kochiana, “Lecidea” fuscescens, “L.” fuliginosa, “L.” olivascens and Lecidella anomaloides ought to be excluded from the checklist (Trass, 1970), as they appeared to be misidentifications. Six species – Cecidonia umbonella, Lecidea plana, Lecidella scabra, Placynthiella dasaea, P. oligotropha and Trapeliopsis pseudogranulosa are new for Estonia. This study was carried out in 1995–1997 and was based on the herbarium collections, kept in the University of Helsinki (H), International Center for Environmental Biology (ICEB) in Tallinn, Ecological Institute (IE) in Tallinn, University of Riga (RIG), Estonian Nature Museum (TAL), Tallinn Botanic Garden (TBA), the Institute of Botany and Ecology of the University of Tartu (TU) and Uppsala University (UPS). The references in literaure have also been taken into account: Bruttan (1870), Ekman et al. (1991), Mereschkowsky (1913), Moberg (1992), Räsänen (1931) and Trass (1967, 1970). The morphological characters of taxa were examined using a stereo lens MBS-9, the anatomical characters using a light microscope MBI-3. Cross sections of fruitbodies were made by hand and then mounted in water, 10% KOH or Lugol’s solution. The “spot tests” were made on the thallus or medulla using 10% KOH (K), sodium hypochlorite (C), p-phenylendiamine in ethanol (Pd) or Lugol’s solution (I). Chemical analyses of secondary products of lichens were carried out according to standardized TLC methods described by Culberson & Kristinsson (1970) and Culberson (1972). The following keys were used to identify the specimens: Foucard (1990), Gowan & Ahti (1993), Hertel (1995), Magnusson (1952b), Printzen (1995), Purvis et al. (1992), Tønsberg (1992), Vainio (1934) and Wirth (1995). 108 Folia Cryptog. Estonica CHECKLIST OF TAXA Genera and species are listed alphabetically. Nomenclature follows Santesson (1993), but recent changes are also taken into account. Species, the systematical position of which is uncertain, are marked with quotation marks (“ ”). Synonymes, which have been used in Estonian lichenological literature, are also included. New taxa for Estonia are given in bold, doubtful species are marked with a question mark (?), exctinct species with an asterisk (*). * ADELOLECIA KOLAENSIS (Nyl.) Hertel & Rambold (syn.

The phylogenetic hypothesis based on ITS sequences suggest that ascus characters cannot be used as characters to distinguish genera within cetrarioid lichens but pycnoconidial shape is representative for larger groups. Tuckermannopsis as a polyphyletic genus is regarded as a key group for a better phylogenetic understanding of cetrarioid lichens. Kokkuvõte: A. Thell. Mõnede tsetrarioidsete liikide fülogeneetilised seosed Briti Kolumbias, rõhuasetusega perekonnale Tuckermannopsis. Analüüsitakse seitsme Briti Kolumbias (Kanada) esineva tsetrarioidse samblikuliigi – Ahtiana sphaerosporella, Esslingeriana idahoensis, Kaernefeltia merrillii, Tuckermannopsis americana, T. platyphylla, T. subalpina jaVulpicida canadensis – omavahelisi fülogeneetilisi seoseid, samuti seoseid seitsme muu tsetrarioidse liigiga, kasutades parsimoonset analüüsi. ITS sekventsidel põhineva fülogeneetilise hüpoteesi kohaselt ei saa eoskoti tunnuseid kasutada tsetrarioidsete samblike perekondade eristamisel, kuid püknokoniidide kuju on sobiv tunnus suuremate rühmade eristamiseks. Polüfüleetilist perekonda Tuckermannopsis võib käsitleda kui võtmerühma tsetrarioidsete samblike fülogeneesi paremaks mõistmiseks. INTRODUCTION The lichen flora of British Columbia, acknowledged for its richness, comprises to 35 out of approximately 135 cetrarioid species in the latest world list (Goward et al., 1994; Randlane et al., 1997). In autumn 1996, I had the opportunity to collect fresh material of cetrarioid lichens in British Columbia. During a stay at the University of British Columbia, I started molecular work on the group. The internal transcribed spacer (ITS) regions of the mycobiont’s nuclear ribosomal DNA (rDNA) gene appeared to be particularly suitable for comparing closely related species and genera. This gene has already been used in a study of populations of Platismatia s.l. and other cetrarioid species (Thell et al., 1998; Thell & Miao in prep.). Several sequences resulting from these studies (Cetraria islandica, C. sepincola, Flavocetraria cucullata, Platismatia glauca, Tuckermannopsis chlorophylla and Vulpicida pinastri) were selected for a comparison with new sequences from seven boreal to subalpine species from British Columbia (Ahtiana sphaerosporella, Esslingeriana idahoensis, Kaernefeltia merrillii, Tuckermannopsis americana, T. platyphylla, T. subalpina and Vulpicida canadensis). As part of a larger survey of the phylogeny of cetrarioid lichens, this investigation focuses mainly on the relationships of some species assigned to Tuckermannopsis. The genus Tuckermannopsis was introduced by Gyelnik (1933), who distinguished it from Nephromopsis by the absence of pseudocyphellae on the lower surface. The generic name was not commonly used by lichenologists until it was reinstated by Lai (1981), who combined several taxa in Tuckermannopsis. Hale (in Egan, 1987), Weber (in Egan, 1991), Kurokawa (1991) and Kärnefelt et al. (1993) transferred additional taxa to the genus. Several of these taxa have recently been assigned to other genera, i. e. Ahtiana, Allocetraria, Kaernefeltia, Melanelia and Vulpicida (Mattson & Lai, 1993; Thell, 1995, Thell et al., 1995b, c; Thell & Goward, 1996). Currently, 11 taxa are assigned to Tuckermannopsis but still today the genus appears heterogeneous. Cetrarioid lichens have been divided into three categories and may also include parmelioid genera (Kärnefelt et al., 1992). Two of these groups, centered around Cetraria s. str. and 114 Folia Cryptog. Estonica Tuckermannopsis, included taxa almost exclusively with an origin in Cetraria. The third group contains taxa with asci of the Melanelia type which is present in the majority of the Parmeliaceae (Thell et al., 1995b). MATERIAL AND METHODS I. Selected material The lichen samples used for the study and cited below were collected in British Columbia 1995–96 and are stored together with DNA isolations in the herbaria LD, TDI (TerraGen Diversity Inc.) and UBC. Ahtiana sphaerosporella: Joffre Lake, Miao & Taylor, DNA#AT83 (TDI#211). Esslingeriana idahoensis: Clearwater, Goward TG-961354, DNA#AT145 (UBC); Goward TG-961348, DNA#AT146 (UBC). Kaernefeltia merrillii: Clearwater, Thell BC-9698, DNA#AT190; Whistler, Thell & Veer BC-9670, DNA#AT71 (LD). Tuckermannopsis americana: Joffre Lake, Miao & Taylor, DNA#AT82 (TDI#210); Wells Gray Park, Goward TG-961350 (UBC). Tuckermannopsis platyphylla: Whistler, Thell & Veer BC-9675, DNA#AT75 (LD); Kamloops, Thell & Veer BC9643, DNA#AT43 (LD). Tuckermannopsis subalpina: Burke Mtn., Thell BC-9606, DNA#AT109 (LD). Vulpicida canadensis: Kamloops, Thell & Veer BC-96250, DNA#AT36 (LD); Jackson Flats, Miao, DNA#VM174 (TDI#146). II. DNA preparation The DNA was isolated following the procedure of Thell et al. (1998). Fragments were amplified with the primers ITS5 and ITS4 (White et al., 1990) using AmpliTaq DNA Polymerase (5 U/ µl) according to the manufactorers protocol. All samples were PCR-amplified and agarose purified twice. A PCR was performed for 30 cycles with the following cycling conditions: denaturation at 94°C for 1 min., annealing at 48°C for 1 min., and extension at 72°C for 45 seconds. The second PCR differed from the first by an elevated annealing temperature of 53°C (Thell et al. 1998). Both complementary strands were sequenced using Dye Terminator Cycle Sequencing Ready Reaction Kit (Perkin Elmer) according to the manufactorers instructions. ITS5, ITS4, ITS3 and ITS2 were used as sequencing primers (White et al., 1990). Cycle sequencing was carried out for 25 cycles with denaturation at 96°C for 10 seconds, annealing temperature at 50°C for 5 seconds, and extension at 60°C for 4 minutes. The DNA was cleaned through CENTRI-SEP columns (Princeton Separations, Inc.). Sequenced fragments were analysed using an ABI Prism 377 DNA automatic sequencer (Perkin Elmer). III. Alignment and phylogenetic analysis The ITS sequences were aligned with SeqApp/CAP 2, followed by a slight adjustment by hand (Table 1) and transferred to PAUP 3.0 (Gilbert, 1993; Huang, 1992). The consensus tree from 500 bootstrap replicates is presented. This tree was obtained using the branch and bound option (Fig. 1). RESULTS I. The sections of the ITS region and flanking parts The amplified fragment of nuclear rDNA including the ITS region is about 560 base pairs long in cetrarioid lichens, and can be divided into five easily distinguished sections: The last part of the SSU rDNA gene (1) at the 5’ end followed by the highly variable ITS 1 section (2), the conserved 5.8 S rDNA (3), the ITS 2 section (4), which is somewhat less variable than ITS 1, and, finally the 5’-end of the large conserved LSU rDNA gene (5). In the alignment, the five sections are recognized at the following sites (Table 1): 1: 1–33, 2: 34–223, 3: 224–381, 4: 382–536 and 5: 537–577. Group I introns of c. 220 nt length, which are excluded from the analyses, were found close to the end of the small subunit ribosomal DNA gene at position 1516 in four species (Gargas et al., 1995). II. Variation in ITS1 and ITS2 The variation within and between species is restricted to the ITS 1 and ITS 2 regions, which are rapidly degraded during rRNA processing (between the bases 33 and 224 and 380–535). As in related investigations (Thell et al., 1998; Thell & Miao in prep.), a larger variation was found in the ITS 1 when compared with ITS 2. 115 In this study, infraspecific variation was found at 16 positions in the ITS 1 section but only at two in ITS 2 (Table 1). III. The sequenced species and infraspecific variation 1. AHTIANA SPHAEROSPORELLA (Müll. Arg.) Goward. Only one specimen, which included a group I intron, was available for molecular studies from this species (DNA#AT83). 2. ESSLINGERIANA IDAHOENSIS (Essl.) Hale & M.J. Lai. Two samples (DNA#AT145, 146) from different localities in the same area had identical sequences. 3. K AERNEFELTIA MERRILLII (Tuck.) A. Thell & Goward. The two studied specimens (DNA#AT71, 190) were morphologically similar. Their sequences, however, differed at several positions: 113, 114, 146, 181 and 187 in the ITS 1 section, and at 456 and 527 in the ITS 2 section (Table 1). 4. TUCKERMANNOPSIS AMERICANA (Spreng.) Hale [syn. Cetraria ciliaris Ach. var. halei (W. L. Culb. & C. F. Culb.) Ahti]. The following sites were different in two sequenced specimens: 34, 99, 113, 136, 138, 143, 166, 201, 206 and 211. Group I introns were found in both sequences (DNA#AT82, 148). 5. TUCKERMANNOPSIS PLATYPHYLLA (Tuck.) Hale. The ITS region differed only at one position in both samples sequenced: 168 (Table 1). Group I introns were detected in both sequences (DNA#AT43, 75). 6. TUCKERMANNOPSIS SUBALPINA (Imshaug) Kärnefelt. A group I intron was detected in the single sample sequenced (DNA#AT109). 7. VULPICIDA CANADENSIS (Räsänen) J.-E. Mattsson & M.J. Lai. The two sequences (DNA#AT36 and DNA#VM174) were identical (Table 1). DISCUSSION Using Platismatia as the outgroup taxon, two main group where apparent in the ITS phylogeny (Fig. 1). One of these, supported by a bootstrap value of 71, includes Cetraria islandica, C. sepincola, Vulpicida canadensis, V. pinastri and Tuckermannopsis subalpina. Vulpicida contains two distinct species groups. One group, containing the North American endemics V. canadensis and V. viridis, is Fig. 1. The bootstrap consensus tree based on ITS sequences from Table 1. Tree length = 262, CI = 0.537, generated using the branch and bound option in PAUP 3.0. The numbers above or to the right of the branches are substitution numbers per branch. Branch lengths are proportional to the substitution numbers. Bootstrap percentages (from 500 replicates) are in bold face below the branches. characterized by citriform conidia and asci with less amyloid and smaller tholi. The other group, including four species, produces sublageniform conidia and asci showing a strong amyloid reaction in the tholus (Mattsson & Lai, 1993; Mattsson, 1993). These two groups, represented by one species each in the analysis appeared as a monophyletic genus. The two species of Cetraria included, C. islandica and C. sepincola, did not form a monophyletic group. This is not surprising because only C. islandica is considered as a Cetraria in a strict sense (Kärnefelt et al., 1993). Cetraria sepincola has asci of Lecanora type (Melanelia form) instead of Cetraria type (Thell et al., 1995b). However, more species related to C. sepincola, e.g. C. fendleri and C. weberi, need to be analysed before an alternative taxonomy might be considered. At least, a position in Tuckermannopsis for C. sepincola, as proposed by Hale (in Egan, 1987), is not supported by ITS data. C. islandica and C. sepincola are on a polytomous branching with Vulpicida (Fig. 1) 116 Folia Cryptog. Estonica Table 1. ITS sequences of seven cetrarioid species from British Columbia. Sequences of Esslingeriana idahoensis and Vulpicida canadensis were identical within the species * Infraspecific variation in Kaernefeltia merrillii, Tuckermannopsis americana and T. platyphylla 117 Table 1 (continued) 118 Folia Cryptog. Estonica Table 1 (continued) 119 Table 1 (continued) 120 Folia Cryptog. Estonica and the ITS data suggests that Vulpicida and Cetraria s. str. are quite close. This is surprising considering the chemical differences. Tuckermannopsis subalpina forms a basal clade in the first main group. Interestingly, Kärnefelt (1979) pointed out earlier that Cetraria species and Masonhalea are closely related to Tuckermannopsis subalpina (earlier Cetraria subalpina), but more recent studies on reproductive characters suggested a position in Tuckermannopsis for this species together with closely related T. inermis (Kärnefelt et al., 1993). However, both taxa belong to neither Tuckermannopsis nor Cetraria, as suggested by ITS data as well as by morphological characters: an one-layered cortex, spherical ascospores and asci with large axial bodies does not support a position in Cetraria, whereas the pycnocondial type – a long, narrow shape with sharp ends – differs from the dumbbell shape characteristic for the genus Tuckermannopsis (Kärnefelt, 1979; Kärnefelt et al., 1993). The other main group of cetrarioid taxa includes Ahtiana sphaerosporella, Kaernefeltia merrillii, Tuckermannopsis americana, T. chlorophylla, Flavocetraria cucullata, the monotypic genus Esslingeriana and Tuckermannopsis platyphylla. This group is supported by a bootstrap value of 51 (Fig. 1). Tuckermannopsis platyphylla has a characteristic appearance with large, almost Umbilicaria-like papillate and tuberculate lobes (Esslinger, 1973). Tuckermannopsis orbata is presumably the most closely related species but T. platyphylla may also be difficult to separate from broad-lobed specimens of Kaernefeltia merrillii, as well. The bootstrap consensus tree would support a new generic position for T. platyphylla (Fig. 1), but additional taxa have to be examined before an alternative systematic position is proposed. Esslingeriana idahoensis, the rarest of the lichens represented here, is an example of a cetrarioid lichen with both laminal and marginal apothecia and pycnidia. Its morphology is very distinct, characterized by a foliose habit, a grey upper surface and large, dark pigmented cells in the lower cortex. Atranorin and endocrocin are distinct secondary compounds (Esslinger, 1971; Kärnefelt et al., 1992). The long branch of 28 steps agrees with an isolated position for this monotypic genus. The genus Flavocetraria is characterized by asci of Cetraria type and the genus was earlier presumed to have close affinities with Cetraria s. str. (Kärnefelt et al., 1992). The unexpected position of F. cucullata presented here indicates that Cetraria is quite distinct from Flavocetraria. The pycnoconidia, however, are dumbbell shaped, a character shared with all taxa in this second main group of the bootstrap consensus tree (Fig. 1). Preliminary data suggest that Flavocetraria cucullata and F. nivalis group together as a monophyletic genus (Thell & Miao in prep.). The sister group of Flavocetraria cucullata included British Columbian species in a polytomous branching (Fig. 1). One of these species is Tuckermannopsis americana, which is represented by two specimens on the tree. This taxon is indistinguishable from the type species, T. ciliaris, and sometimes recognized only at variety level, as Cetraria ciliaris Ach. var. halei (W. L. Culb. & C. F. Culb.) Ahti (in Brodo, 1984: 100; Goward et al., 1994). It is recognized by presence of alectoronic acid and occasionally by α-collatolic acid (Culberson & Culberson, 1967). Similar as for the chemical species of Cetrelia, the species status for this taxon is uncertain. The four species composing the T. ciliaris group, T. americana, T. ciliaris, T. microphyllica and T. orbata, are closely allied according to morphology and secondary chemistry (Culberson & Culberson, 1967). The bootstrap consensus tree (Fig.1) suggests that if Tuckermannopsis chlorophylla with world-wide distribution and probably also the related eastern Asian T. gilva and T. ulophyllodes are also maintained in Tuckermannopsis, then the genera Ahtiana and Kaernefeltia have to be included as well. Ahtiana sphaerosporella is morphologically distinct form other groups and was originally distinguished from Parmelia as a monotypic genus – primarily on the basis of small and spherical ascospores (Goward, 1985), whereas Ahtiana aurescens and A. pallidula were transferred later from Cetraria (Thell et al., 1995a). Ahtiana is presumably most closely allied to the likewise yellow, Eastern Asian genus Tuckneraria which differs in the presence of cilia and pseudocyphellae (Randlane et al., 1994). The type species of Tuckneraria and Allocetraria must certainly be sequenced to obtain a more detailed picture of the evolution of the group. 121 Kaernefeltia was recently described and differs from other cetrarioid genera by its unique combination of characters (Thell & Goward, 1996). However, there is considerable morphological variation in the genus and the growth form of Kaernefeltia merrillii varies from broadly foliose to subfruticose. Unfortunately, suitable material for molecular studies was not available from the type species K. californica. At present the data show that Tuckermannopsis is not only poorly delimited to members of other genera in the current circumscription but species assigned to Tuckermannopsis are polyphyletic according to the ITS data. Also, the status of several other genera is difficult to ascertain until more species assigned to Tuckermannopsis are sequenced. Even though this taxon is heterogeneous, it appears to be a key group for a better phylogenetic understanding of cetrarioid lichens. To improve the phylogenetic hypothesis, further cetrarioid genera also need to be compared with non-cetrarioid representatives from different segregates of the Parmeliaceae. This is especially important since gross morphology or chemistry are not supported as characters to separate larger units in neither parmelioid nor cetrarioid lichens (for chemistry compare with Poelt & Leuckert, 1993). As a consequence, generic rearrangements in cetrarioid lichens should be carried out with great care until a more detailed phylogeny is at hand.

INTRODUCTION In August 24–30, 1991 the lichen flora of three wooded meadows in Estonia was investigated, two of which were situated in the island of Saaremaa and one on the Estonian coast c. 30 km E of Saaremaa (Fig. 1, localities no. 1, 4, 5). Some additional localities were also shortly visited, including two in the vicinity of Tartu, where the excursion ended up (Fig. 1, localities 2, 3, 6, 7). Traditionally managed wooded meadows in Sweden usually have a species rich lichen flora, including several red-listed species. This is mainly due to the continuity in tree growth in combination with the open forest structure, characteristic of traditional management practices. The red-listed species are mainly found on broad-leaved deciduous trees (Thor, 1998). Also the Estonian wooded meadows investigated proved to be species rich. Areas with wooded meadows (and wooded pastures) have decreased dramatically both in Sweden and Estonia and are now restricted to very small areas. The remaining wooded meadows and pastures consequently have high conservation values. The trend away from traditional management practices of such habitats, resulting in denser forest structure, has become a threat even in protected areas in Sweden. Practices such as pollarding is apparently positive to some lichens, e.g. Caloplaca chrysophthalma Degel., a red-listed species in Sweden (Thor, 1996). Pol- Fig. 1. Localities visited. larded trees, however, are rare in the Estonian wooded meadows investigated compared with those of Gotland, Sweden, also investigated by the authors (together with R. Sundin; Nordin et al., 1990, 1991, 1992, 1996). A few species found in the Estonian wooded meadows were not found in Gotland, e. g. Physcia semipinnata (J. F. Gmelin) Moberg (AN & GT 164, locality 4, on Fraxinus excelsior). RESULTS Altogether 12 species new to Estonia were found in the wooded meadows, six exclusively in Laelatu, two exclusively in Tagala, one exclusively in Loode, two in Laelatu and Tagala 124 Folia Cryptog. Estonica together, and one in the three of them. Four additional species new to Estonia were found at other localities specified below. At the same excursion Cliostomum flavidulum Hafellner & K. Kalb was collected and published as new to Estonia by Nordin et al. 1996 (as Lecanora navarrensis Etayo). One more lichen new to Estonia – Phaeophyscia endophoenicea (Harm.) Moberg – was collected in Tartumaa Co., Luke park. This finding has been published already in the macrolichen flora of Estonia (Trass & Randlane, 1994). Four of the species reported here are red-listed in Sweden, Buellia violaceofusca (Care demanding), Cyphelium sessile (Care demanding), Gyalecta truncigena (Vulnerable) and Opegrapha sorediifera (Vulnerable). The material will be deposited in UPS. For collections investigated by TLC the results are given together with the collection numbers. The numbers (1–7) refer to localities.

INTRODUCTION In accordance with Takhtadjan (1986) floristic division, Caucasus and the Crimea are situated on the boreal and tethyan subkingdoms of Holarctis. Although circumboreal elements dominate the flora of Caucasus and the Crimea, many relict islands of an ancient tertiary flora remain. There are two main centres of the tertiaty flora – the dry subtropical Hyrcanian forest and the wet subtropical forests of Colchis. Relict Hyrcanian forests (the name originates from the ancient name of the Caspian Sea) form a separate province of the Irano-Turanion region, and occupy the northeastern slope of the Talysh range. The majority of forest-forming trees, such as Acer vetulinum Boiss., Albizia julibrissin Durazz., Gleditschia caspia Desf., Parrotia persica C.A.M., Quercus castaneifolia C.A.M., Zelkova carpinifolia (Pall.) C. Koch are endemics of the mesophilous tertiary forest. The flora of the Colchian type (this name originates from the name of the territory in West Georgia – the lowlands of the river Rioni) form the Euxine province, and occurs in the western Caucasus – Adzharssk, Abkhassk and Krasnodar territories. In contrast to the Hyrcanian province, where conifers do not occur, the main forest-forming trees in the Euxine province are endemic conifers – Abies nordmanniana (Stev.) Spach and Picea orientalis (L.) Link – together with Acer trautvetteri Medw., Carpinus betulus L., Fagus orientalis Lipsky, Pinus kochiana Klotzsch ex C. Koch, Quercus spp., Tilia begoniifolia Stev. The forests of the Crimea are mainly of a broad-leaved Fagus-Quercus type, and were included by Takhtadjan (1986) in a separate Crimean-Novorossijsk province. The flora of these forests is quite similar to that of the Colchian type. During our field trips in Caucasus and the Crimea more than 50 species of calicioid lichens and fungi were found. In this paper only some rare, threatened, or earlier overlooked species are included. All higher plants are named according to Czerepanov (1995), and lichens according to Santesson (1993). MATERIAL AND METHODS The material was collected from several localities in Caucasus and the Crimea by the author (Fig. 1) in the period from 1982–1993. The results are also based on herbarium material from LE, LEP and KW. For SEM, material was mounted on specimen stubs, air-dried and coated with gold. Estimates of the apothecium height, capitulum width, stalk width, ascus length, ascus width, spore length and spore width (for Chaenothecopsis trassii) are given in the following way: (min) a–b (max) – or for combinations of length and width: (min) a–b × c–d (max)– where a (and c) represent the arithmetic mean minus 1 128 Folia Cryptog. Estonica Fig. 1. The map of Caucasus and Crimea. standard deviation and b (and d) the arithmetic mean plus 1 standard deviation. The extreme minimum (min) and maximum (max) values are given within parentheses. THE SPECIES CHAENOTHECA SERVITII Nadv., Fedde, Repert. 36: 308 (1934). Caucasus.

On mycelium of Hormiscium pinofilum (Nees) Lind., growing on twigs of Picea orientalis. Mycelium well developed, consisting of pale, irregular intervowen hyphae about 3 µm thick, mixed with the host mycelium. Algae not present in the substrate. Apothecia small, 0.2–0.4 mm high, on pale stalks. Capitulum ellipsoidal, black, 0.06–0.1 mm in diameter. Hymenium and hypothecium pale. Excipulum well-developed as a continuation of the outer part of the stalk, consisting of 4–5 layers of periclinally elongated cells, with a constricted margin. Stalks straight, 0.02–0.03 mm in diameter, consisting of loosely interwoven pale hyphae. Mature asci 55–70 × 4–5 µm, cylindrical, always with a canal in the apical thickening. Spores uni- b Fig. 2. Chaenothecopsis jaczevskii. a – apothecium, assotiated with mycelium of Hormiscium pinophilum; b – spores. 130 Folia Cryptog. Estonica seriately arranged in the asci, periclinally orientated, 1-septate, narrowly-ellipsoidal with rounded ends, pale-brown, 7–9 × 3–4 µm, with a well-developed, areolate ornamentation. All parts of the apothecium K-, H-, strongly swelling with K. Hymenium slightly blue-green with iodine (Fig. 2). C. jaczevskii is characterized by its green in fresh material (Voronichin, 1927), well developed mycelium, small apothecia on pale stalks and ellipsoidal capitula, constricted excipulum margin and one-septate ornamented spores. C. jaczevskii is known from one collection only and the material is rather scanty for suppling a good description, but this is evidently a distinctive species. In many respects it is quite different from other genera of calicioid fungi, and only placed in Chaenothecopsis tentatively, since the generic delimitations in Mycocaliciaceae are in need of reappraisal.

Azerbaijan, Lencoran region, Belyasar, 1987 Titov, 1431, 1443, 1458 (LE). On thallus of Haematomma ochroleucum (Neck.) Laundon, growing on bark of Fagus orientalis. C. ochroleuca occurs on the bark of deciduous trees in humid situations in temperate forests. A rare species, C. ochroleuca is previously known from some localities of the northern Eurasia. Originally described from Germany (Koerber, 1865), it has also been reported from Central Europe (Nádvorník, 1934, 1942; Tibell & Ryman, 1995) and the Russian Far East (Titov & Tibell, 1993).

All parts of the apothecium with red pigment turn aeruginose with K, but are H- (Fig. 3, a–c). Caucasus. Azerbaijan, Lencoran region, Belyasar, 1987 Titov 1766 (Holotype: LE, isotype: UPS), Vyshnikesh, 1427 (LE). On bark of Fagus orientalis. C. trassii is characterized by its small, short-stalked apothecia, the non-septate ellipsoidal spores, the ascocarp structure and by containing red crystals in hymenium, which yield a green reaction with K. C. trassii is rather similar to C. rubescens, which also has short-stalked apothecia which contain a red pigment, but it differs in having smaller, smooth spores and a different K reaction. C. trassii is also somewhat similar to C. ochroleuca, which has a K+ aeruginose reaction of the capitulum, but fusiform dark spores and often white pruinose stalks. C. nana and C. amurensis both have short-stalked apothecia and non-septate spores and could be mistaken for C. trassii, but differ in having a negative K reaction. C. trassii is named in honour of Prof. H. Trass on the occasion of his 70th birthday for his invaluable contribution to the exploration of the Russian lichen flora. CHAENOTHECOPSIS USSURIENSIS Titov, Nord. J. Bot. 13: 326 (1993). Caucasus. Azerbaijan, Astara region, Sym, 1987 Titov 1435 (LE). On bark of Quercus castaneifolia. C. ussuriensis is previously known only from the southern Far East of Russia and north-east of China, and seems to be a common and widely distributed but earlier overlooked species in relict Pinus-deciduous forests. The occurrence of this species in the Gyrcanian forest may indicate a connection between the tertiary forests of Caucasus and the Far East. CHAENOTHECOPSIS VAINIOANA (Nádv.) Tibell, Publ. Herb. Univ.

M. albonigrum occurs on lignum of trees in open situations. It is known from Australia, and North and South America (Tibell, 1987). M. albonigrum is quite similar to M. subtile, which is a very widely distributed species, but differs in having an excipulum formed by isodiametric cells. This species might have been overlooked since it is rather difficult to identify. It is here reported as new for Eurasia. PYRGIDIUM MONTELLICUM (Beltr.)

The patterns of distribution are explicable by the description of the ecological range of the treated species. Kokkuvõte: Perekondade Anaptychia, Heterodermia, Hyperphyscia jaPhaeophyscia (Physciaceae) levik Austrias.

EINLEITUNG DIE VERBREITUNG IN ÖSTERREICH Die lobaten Gattungen Anaptychia, Heterodermia, Hyperphyscia und Phaeophyscia aus der Familie der Physciaceae sind hinsichtlich ihrer ökologischen Ansprüche und ihrer Verbreitung sehr unterschiedlich. Die Abgrenzung einiger Sippen ist zum Teil schwierig (vgl. Moberg, 1977; Hafellner et al., 1979). Nach Hafellner et al. (1979) sind z. B. die Gattungen Anaptychia und Physconia typisch nordhemisphärisch temperate Genera, Heterodermia tropischsubtropische Breitgürtelelemente und Hyperphyscia ebenfalls tropisch-subtropisch mit einigen temperaten Ausläufern. Die Gattungen Physcia und Phaeophyscia wiederum haben eine sehr weite Verbreitung, die von der Arktis und der Antarktis bis in die Tropen reicht, auf einer Fülle von Substraten, sofern diese einen bestimmten Grad an Eutrophierung aufweisen. Die saxicolen Arten haben sehr unterschiedliche Ansprüche auf das Substrat, was den Säuregrad betrifft (vgl. Moberg, 1977). Die Wuchsmöglichkeiten für Flechten sind in Österreich auf Grund der anstehenden Gesteine, der Substratvielfalt, der orographischen und klimatischen reichen Gliederung äußerst vielfältig und bieten Lebensraum für Flechten mit den unterschiedlichsten ökologischen Ansprüchen. Am Beispiel einiger Verterter aus der Familie der Physciaceae sollen die Verbreitungsmuster dargestellt und diskutiert werden. Die Literaturangaben über Funde in Österreich zwischen 1860 und 1993 sind aus Türk & Poelt (1993) zu entnehmen. ANAPTYCHIA BRYORUM Poelt, syn.: A. fusca (Huds.) Vain. var. stippea auct. (Abb. 1) Literatur: Türk & Poelt, 1993; Hafellner, 1993; Hofmann et al., 1995. Anaptychia bryorum wächst zumeist an Steilflächen über Moosen und Pflanzenresten in der alpinen Stufe (Poelt & Vêzda, 1977). In Österreich bevorzugt sie sauren bis leicht kalkhaltigen Untergrund in den Zentralalpen, nur gelegentlich dringt sie in die Nördlichen Kalkalpen (Göllmassiv, Steinernes Meer, Hochkönig) vor. ANAPTYCHIA CILIARIS (L.) Körb. (Abb. 2) Literatur: Türk & Poelt, 1993; Geyer, 1985; Neuwirth & Türk, 1993; Pfefferkorn & Türk, 1993; Hafellner & Maurer, 1994; Hofmann et al., 1995; Baumgartner & Türk, 1996; Berger, 1996; Boom et al., 1996; Pfefferkorn, 1996; Pfefferkorn & Türk, 1997. Diese formenreiche Art (vgl. Poelt & Vêzda, 1977) war mit ihren epiphytisch lebenden Vertretern früher weitaus häufiger als heute. In ihrem heutigen Hauptverbreitungsgebiet, im Mittelgebirge der Böhmischen Masse und im Alpenvorland, tritt sie meist nur in wenigblättrigen, deformierten Thalli auf.

(Abb. 3) Literatur: Türk & Poelt, 1993; Hofmann, 1993; 1994; Pfefferkorn, 1996; Türk, 1996; Pfefferkorn & Türk, 1997. Heterodermia obscurata ist eine ozeanische Flechte, deren Hauptverbreitung in den ozeanischen Bereichen im Südwesten Europas (Küsten von Portugal, Spanien, Frankreich und Großbritannien) liegt (vgl. Schauer 1963). An niederschlagsreichen Orten mit gemäßigtem Temperaturregime findet sie sich auch in den Alpen ein, vornehmlich in einer Seehöhe zwischen 500 bis 700 Meter. Sie siedelt gern auf bachbegleitenden Weiden (Salix sp.) und Esche (Fraxinus excelsior). Der von Schauer (1963) angegebene Fund vom Langbathsee am Nordabfall des Höllengebriges in Oberösterreich konnte im Zuge neuerer Begehungen zwischen 1975 und 1996 nicht mehr bestätig werden. Heterodermia obscurata gehört zu den vom Aussterben bedrohten Arten in Österreich (Gefährdungsstufe 1). HETERODERMIA SPECIOSA (Wulfen) Trevis. (Abb. 4) Literatur: Türk & Poelt, 1993; Hofmann, 1993; Türk & Breuss, 1994; Rücker & Wittmann, 1995; Pfefferkorn, 1996; Türk, 1996; Pfefferkorn & Türk, 1997. Heterodermia speciosa siedelt auf bemoosten Stämmen und auf Seitenästen von Laubbäumen (Salix sp., Alnus incana, Acer pseudoplatanus, Fagus sylvatica etc.), in extrem luftfeuchten Orten (enge Talschluchten, schattige Täler, Nähe von Wasserfällen) kommt sie auch auf Nadelbäumen vor. Als ozeanische Flechte bevorzugt sie Gebiete mit hohen Niederschlagsraten von der montanen (ab etwa 400 Meter) bis in die hochmontane (etwa 1400, im Extremfall 1600 Meter) Stufe. Sie fruchtet selten – und wenn, dann zumeist an bachnahen Stämmen und Ästen. Ein geschlossenes Verbreitungsgebiet weist sie in den Tälern der Nördlichen Kalkalpen auf, in den Zentralalpen tritt sie nur an sehr luftfeuchten Standorten auf. In den südlichen Kalkalpen bevorzugt sie die niederschlagsreichen Abschnitte der Karnischen Alpen und der Karawanken. Außerhalb der Alpen dürfte sie heute in Österreich ausgestorben sein. Über die Verbreitung in Europa siehe Schauer (1965). HYPERPHYSCIA ADGLUTINATA (Flörke) H. Mayrhofer & Poelt, syn.: Physciopsis a. (Flörke) M. Choisy (Abb. 5) Literatur: Türk & Poelt, 1993; Hafellner & Maurer, 1994; Türk et al., 1994; Hofmann et al., 1995; Obermayer, 1996. Die tropische Gattung Hyperphyscia ist in Europa lediglich mit einer Art – Hyperphyscia adglutinata – vertreten. Diese Flechte ist wohl eine der kleinstwüchsigen Blattflechten unserer heimischen Flora. Ihr graugrün bis graubraun gefärbtes Lager liegt dem Substrat sehr eng an. Sie bevorzugt subneutrale bis staubimprägnierte Borke von freistehenden Laubbäumen (Aesculus hippocastanum, Robinia pseudacacia, Tilia cordata, Populus sp., Juglans regia u.a.) in wärmegetönten Lagen außerhalb der Alpen. In den Alpen folgt sie gelegentlich tiefer gelegenen Flußtälern. Sie bevorzugt die kolline (ab 180 Meter) bis niedermontane (ca. 700 Meter) Stufe. Aus Vorarlberg, Tirol und Kärnten liegen bisher keine Fundmeldungen vor. In Europa ist sie mitteleuropäisch-mediterran verbreitet. PHAEOPHYSCIA CERNOHORSKYI (Nádv.) Essl., incl. P. strigosa (Poelt & Buschardt) Golubkova (Abb. 6) Literatur: Türk & Poelt, 1993; Hofmann et al., 1995. Phaeophyscia cernohorskyi bevorzugt ähnlich wie Ph. insignis südeponierte, trockenwarme Standorte. Neben ihrem gehäuften Auftreten in collinen bis submontanen Lagen des südöstlichen Alpenrandes stößt sie inneralpin (unter geeigneten kleinklimatischen Bedingungen) auch bis in hochmontane Lagen vor. Sie wächst überwiegend auf kalkhältigen Gesteinen oder darüberliegenden Moosen. P HAEOPHYSCIA CHLOANTHA (Ach.) Moberg, syn.: Physcia luganensis Mereschk.; Physciella chloantha (Ach.) Essl.

Phaeophyscia chloantha tritt in Österreich nur in geringer Abundanz auf, die aktuellen Funde betreffen zumeist nur einige wenige Exemplare. Sie wächst in kollinen bis submontanen, selten in montanen, wärmegtönten Lagen auf Laubbäumen mit nährstoffreicher Borke. Ihr höchst gelegener Fundpunkt liegt in 1000 Meter Höhe (Gaisberg bei Salzburg). P HAEOPHYSCIA CILIATA (Hoffm.) Moberg, syn.: Physcia c. (Hoffm) Du Rietz (Abb. 8) Literatur: Türk & Poelt, 1993; Hofmann, 1993; Obermayer, 1993; Türk & Breuss, 1994; Hofmann et al., 1995; Rücker & Wittmann, 1995; Boom et al., 1996; Pfefferkorn, 1996; Pfefferkorn & Türk, 1997. Phaeophyscia ciliata hat hohe Ansprüche an die Feuchte, sie bevorzugt niederschlagsreiche Lagen von der montanen bis hochmontanen Stufe, wo sie auf Laubbäumen wächst. Gelegentlich wächst sie im Kronentrauf von Bäumen auch auf Holzzäunen. Ihr Vorkommen beschränkt sich in Österreich auf den Alpenraum. PHAEOPHYSCIA CONSTIPATA (Norrl. & Nyl.) Moberg (Abb. 9) Literatur: Türk & Poelt, 1993; Hofmann et al., 1995. Phaeophyscia constipata ist eine der wenigen bodenbewohnenden Vertreter ihrer Gattung. Sie wächst auf sehr flachgründigen Kalk- und Dolomitböden, zumeist über Felsen, mit Moosen vergesellschaftet. Ihre Wuchsorte zeichnen sich durch einen hohen Strahlungsgenuß aus, weshalb sie in Österreich die regenarmen, inneralpinen Täler in hochmontanen Lagen bevorzugt. Lediglich in den Nördlichen Kalkalpen kommt sie auch in niederschlagsreicheren Regionen vor (Schober bei Thalgau, in 1300 msm). Sie gehört zu den Seltenheiten der heimischen Flechtenflora. PHAEOPHYSCIA ENDOCOCCINA (Körb.) Moberg, incl. var. LITHOTODES Nyl. (Abb. 10) Literatur: Türk & Poelt, 1993; Obermayer, 1993; Pils & Berger, 1995; Hofmann et al., 1995; Berger, 1996. Diese Flechte siedelt bevorzugt auf nicht zu sauren, silikatischen Gesteinen. Hinsichtlich ihres Feuchtebedürfnisses scheint sie eine sehr weite ökologische Potenz zu haben: sie wächst in der amphibischen Zone klarerBäche, auf zeitweise überrieselten, stark geneigten Felsflächen oder auf überhängenden Felsflächen ohne jede Zufuhr von tropfbar flüssigem Wasser. Auch auf Moosen ist sie anzutreffen. In Österreich ist ihr Hauptverbreitungsgebiet in den Alpen, wo sie von der montanen bis in die alpine Stufe vorkommt. Außerhalb der Alpen ist sie sehr selten. PHAEOPHYSCIA ENDOPHOENICEA (Harm.) Moberg (Abb. 11) Literatur: Türk & Poelt, 1993; Hofmann, 1993; 1996; Neuwirth & Türk, 1993; Obermayer, 1993; Pfefferkorn & Türk, 1993; Berger & Türk, 1994; 1995; Hafellner & Maurer, 1994; Türk & Breuss, 1994; Türk et al., 1994; Rücker & Wittmann, 1995; Baumgartner & Türk, 1996; Boom et al., 1996; Hafellner et al., 1996; Pfefferkorn 1996. Phaeophyscia endophoenicea sucht von vornherein feuchtere Habitate auf, die durch hohe Niederschläge oder große Nebelhäufigkeit ausgezeichnet sind. Zumeist wächst sie zwischen Moosen, was für ihre Wasserversorgung günstig ist. In Österreich kommt sie von der kollinenbis zur hochmontanen (höchster Fundpunkt in 1600 Meter) Stufe vor, sie meidet kalte Regionen, weshalb sie im Gebiet der Böhmischen Masse (Mühl und Waldviertel) nur an wärmebegünstigten Wuchsorten gedeiht. PHAEOPHYSCIA HIRSUTA (Mereschk.) Essl. (Abb. 12) Literatur: Türk & Poelt, 1993; Hofmann, 1993; Türk & Breuss, 1994; Boom et al., 1996. Phaeophyscia hirsuta ist hauptsächlich südeuropäisch verbreitet, lediglich an warmen Standorten dringt sie bis in das südliche Mitteleuropa vor. Sie wächst auf der subneutralen bis schwach sauren Borke von Laubbäumen, die gelegentlich auch leicht eutrophiert sein kann und auf Gestein. Die Zentralalpen Österreichs meidet sie. 141 PHAEOPHYSCIA HISPIDULA (Ach.) Ess.(Abb. 13) Literatur: Türk & Poelt, 1993; Berger, 1996; Hafellner, 1997. Sie gehört zu den absoluten Seltenheiten der heimischen Flechtenflora. Diese of fensichtlich tropisch-ozeanische Flechte kommt in den Bergwäldern des Mittelmeergebietes zerstreut vor (Poelt, 1969) und dringt nur an sehr trockenen, niederschlagsarmen Standorten in die Alpen vor. Außerhalb der Alpen wurde sie im Donautal aufgefunden. PHAEOPHYSCIA INSIGNIS (Mereschk.) Moberg (Abb. 14) Literatur: Türk & Poelt, 1993; Hafellner, 1997. Die Phaeophyscia orbicularis sehr nahe stehende Sippe mit ihrem Verbreitungsschwerpunkt in Südeuropa ist in Österreich großteils auf wärmeexponiertere, colline bis montane Lagen beschränkt. Vereinzelt dringt sie auch bis in die montane Stufe vor. Phaeophyscia insignis siedelt zumeist an Allebäumen, geht aber auch auf (kalkstaubimprägnierte) Moose über. PHAEOPHYSCIA KAIRAMOI (Vain.) Moberg (Abb. 15) Literatur: Türk & Poelt, 1993; Hofmann, 1993; Hofmann et al., 1995. Phaeophyscia kairamoi wächst sowohl epiphytisch auf Laubbäumen als auch auf bemoosten Kalkfelsen. Sie kommt von der montanen bis in die alpine Stufe vor. Hinsichtlich der Feuchteanprüche dürfte sie eine sehr weite Amplitude besitzen. In Österreich ist ihr Vorkommen auf die Alpen beschränkt. PHAEOPHYSCIA LABRATA (Mereschk.) ined., syn.: Physcia labrata Mereschk. (Abb. 16) Literatur: Türk & Poelt, 1993; Baumgartner & Türk, 1996. Phaeophyscia labrata wächst auf der Borke von alten Laubbäumen in Bergwäldern. Ihre hohen Ansprüche auf Feuchtigkeit beschränkt ihr Vorkommen auf ozeanische Lagen (vgl. Schauer, 1965) in der montanen bis hochmontanen Stufe. Sie fehlt nördlich der Donau und in den kontinental geprägten östlichen Landschaften Österreichs. PHAEOPHYSCIA NADVORNIKII (Frey & Poelt) N. S. Golubkova, syn.: Physcia n. Frey & Poelt (Abb. 17) Literatur: Türk & Poelt, 1993; Türk, 1996. Sie ist in Österreich sehr selten. Sie wächst auf Borke am Stamm und an Seitenästen von alten Laub- und Nadelbäumen sowie auf Felsen in sehr feuchten Lagen der montanen bis hochmontanen Stufe. Im Spritzbereich von Wasserfällen kann sie Massenbestände bilden (vgl. Schauer, 1965) PHAEOPHYSCIA NIGRICANS (Flörke) Moberg (Abb. 18) Literatur: Türk & Poelt, 1993; Hafellner, 1993; Ober mayer, 1993; Hafellner & Maurer, 1994; Türk & Breuss, 1994; Türk et al., 1994; Berger & Türk, 1995; Boom et al., 1996. Sie kommt in Österreich von der kollinen bis in die hochmontane Stufe (1600 msm) vor. Sie wächst auf eutrophierten, zumeist kalkhaltigen Gesteinsoberflächen, auf Mörtel, Beton und auchauf staubimprägnierten Baumborken am Stammgrund, wo sie leicht zu übersehen ist. Sie bevorzugt etwas trockenere, wärmegetönte Lagen. Im Voralpenland und in den Mittelgebirgen des Mühl- und Waldviertels tritt sie häufiger auf, in den Alpen ist sie selten. PHAEOPHYSCIA ORBICULARIS (Neck.) Moberg, syn.: Physcia virella (Ach.) Flagey (Abb. 19) Literatur: Türk & Poelt, 1993; Hofmann, 1993; 1994; Neuwirth & Türk, 1993; Obermayer, 1993; Pfefferkorn & Türk, 1993; Hafellner & Maurer, 1994; Türk & Breuss, 1994; Türk et al., 1994; Berger & Türk, 1995; Hofmann et al., 1995; Rücker & Wittmann, 1995; Baumgartner & Türk, 1996; Berger, 1996; Boom et al., 1996; Hafellner et al., 1996; Hafellner & Wittmann, 1996; Pfefferkorn, 1996; Türk, 1996. Phaeophyscia orbicularis ist der häufigst auftretende Vertreter ihrer Gattung. Sie besiedelt alle möglichen Substrate, so sie genügend eutrophiert sind, seien es nun Baumborken oder Gesteinsoberflächen. Auf anthropogenen Substraten kann sie Massenbestände bilden, in Gebieten mit hohem Grad an Lufverunreinigungen ist sie oftmals der einzige Vertreter der Blattflechten. Sie kommt von der kollinen bis in die alpine Stufe vor, wo sie an gut gedüngten Plätzen über Pflanzenresten und auf Gesteinssubstraten wächst.

(Abb. 20) Literatur: Türk & Poelt, 1993; Hofmann, 1993; Boom et al., 1996; Pfefferkorn, 1996; Pfefferkorn & Türk, 1997; Hafellner, 1997. Phaeophyscia pusilloides ist eine typische Flechte alter, weitgehend naturnaher Waldbestände mit dem entsprechenden Bestandesklima in ozeanischg getönten Lagen. Zur Hauptsache ist sie in den Alpen von der montanen bis zur hochmontanen Stufe verbreitet, wo sie die Borke von Laubbäumen (Acer pseudoplatanus, Fagus sylvatica, Fraxinus excelsior, Alnus incana, Salix sp. etc.) besiedelt. Außerhalb der Alpen ist sie äußerst selten. PHAEOPHYSCIA SCIASTRA (Ach.) Moberg (Abb. 21) Literatur: Türk & Poelt, 1993; Obermayer, 1993; Hafellner & Maurer, 1994; Türk & Breuss, 1994; Hafellner & Türk, 1995; Hofmann et al., 1995; Berger, 1996; Hafellner et al., 1996. Phaeophyscia sciastra besiedelt eutrophierte Substrate wie Gesteinsoberflächen (Kalk und basiche Silikate), Holzschindeln, Dächer und Holzzäune. Äußerst selten tritt sie epiphytisch am staubimprägnierten Stammgrund von Laubbäumen auf. Im Gebirge wächst sie in höheren Lagen gern über gesteins- und holzbewohnenden Moosen. Diese morphologisch sehr variable Art kann leicht übersehen werden. Ein geschlossenes Verbreitungsgebiet in Österreich weist sie im Alpenraum auf, im übrigen Österreich tritt sie zerstreut auf. PHAEOPHYSCIA STIRIACA (Poelt) Clauzade & Roux (Abb. 22) Literatur: Türk & Poelt, 1993. Diese Flechte ist submediterran und mediterran verbreitet, an einigen wenigen Stellen dringt sie in die Steiermark vor. Sie wächst auf Boden, Gestein und über bodenbewohnenden Moosen.

Box 47, FIN-00014 University of Helsinki, Finland Abstract: From data of the checklist of lichens and allied fungi of Finland, comprising 1624 taxa (1422 species of lichens, 120 species lichenicolous and 44 species allied non-lichenized fungi), examples of regional species richness and some other statistical values are presented on the basis of their occurrence in the traditional 21 biogeographical provinces. Ca. 10% of the taxa have been recorded in all provinces, but 22.6% are recorded only in one. Some 15.6% of the accepted taxa have their nomenclatural type from Finland. Kokkuvõte: O. Vitikainen.

INTRODUCTION One and a half century of lichen floristics in Finland has accumulated much information, both records in literature and materials in herbaria (see overview by Vitikainen, 1996). The spatial and temporal continuum of these studies, however, is rather tenuous when compared to the situation in countries such as Sweden and England. The lack of a national checklist of lichens of Finland for over one hundred years is one example of evident deficiencies. Even the recent checklist (Vitikainen et al., 1997) should rather be regarded as a stimulus for additional studies than a presentation of well-revised data. However, the information compiled for the list may be used for evaluating some aspects of the lichen flora and the status of its investigation, even if this treatment is not comparable in accuracy with the information on vascular plant flora of Finland given by Lahti and al. (1988), nor does it attempt to analyze the flora elements in the same degree as Trass (1970), for example. RESULTS AND DISCUSSION The Finnish checklist contains 1 624 “accepted” taxa, of which 1 458 are considered lichenized, comprising 1422 species as well as additional 15 subspecies and 21 varieties, and 166 either lichenicolous (120 species and 2 varieties) or allied (44 species) fungi, both latter categories being very poorly studied in Finland. In comparison, the checklist of the lichens of Sweden and Norway (Santesson, 1993) recognizes 2271 accepted species, and in the checklist of Great Britain and Ireland (Purvis et al., 1993) 1660 species with 61 additional infraspecific taxa are accepted. 395 of the lichenized species and 9 subspecies plus 11 varieties of the Finnish checklist are so called macrolichens. In comparison, in the recent macrolichen flora of Estonia 332 species are recognized (Trass & Randlane, 1994), but this area is much smaller and less variable geographically. These Finnish figures, even if indicated as “accepted”, still comprise several imperfectly known or critical taxa, many of which have been described from Finnish materials but not subjected to investigation by modern methods, and considerable changes and amendments of the list are anticipated with progressing taxonomical studies and checking of herbarium materials. For example, there was an increase of 261 species in ten years in the Swedish and Norwegian checklist, and almost one hundred species were added in 13 years to the list of the British Isles (see Santesson, 1993; Purvis et al., 1993). 150 Folia Cryptog. Estonica Numbers of taxa in the biogeographical provinces The numbers of taxa recorded in the 21 biogeographic provinces of Finland (Fig. 1) are presented in Table 1. It should be noted that a low number of provincial records, especially when compared with neighbouring provinces, often indicates less intensive research activity and not actual adverse conditions for lichen growth. The provinces South Häme, Varsinais-Suomi and Uusimaa, with the highest numbers of recorded species – close or over 50 % of the total – are well-known as centres of activity since the early periods of lichen floristics in Finland; in addition, these areas also provide a richer range of habitats than the adjacent provinces. The lowest figure, 193 recorded species for Ladoga Karelia, is explained by the situation that this area is only represented by a small and poorly studied corner of the traditional province, the main part belonging now to Russia. Other areas of less intensive recording than the average, e.g. South Karelia, South Savo, Middle and Oulu Ostrobothnia, Kittilä and Sompio Lapland, with ca. 400 species at most, include wide areas of rather monotonous and uniform oligotrophic boreal forest vegetation and nature with little geological variation and influence of cultivation but additional research will certainly increase the number of species. If the anomalous Ladoga Karelia is omitted, 574 taxa are present in each province on average, i.e the provinces Åland and North Savo represent the average number of taxa. Patterns of species distribution Finland, with its length of over 1 100 km from south to north, provides a gradient of several boreal vegetation zones, ranging from the hemiboreal zone in the three southernmost provinces to hemiarctic areas prevailing in Lapland. Some general observations of the species ranges along this transection can be made, though the limitations of the material should be remembered. Not less than 24.5 % of the taxa are recorded only in one province, and even 11.8 % of the Fig. 1.

Only some 6.7 % of the total number of species have been recorded in all provinces, even if not in the same degree of abundance or frequency throughout the range. Such species include Arctoparmelia centrifuga, Cetraria sepincola, Cladina arbuscula, C. stellaris, Evernia prunastri, Hypogymnia physodes, Parmelia saxatilis and Peltigera aphthosa, among others. With exclusion of Ladoga Karelia the percentage of such widely occurring species is still close to 10 %. This relatively low figure is understandable bearing in mind those underexplored provinces discussed above. Table 1.

Species recorded in all of these three provinces include Acrocordia gemmata, Caloplaca microthallina, Cladina ciliata, C. portentosa, Cladonia foliacea and Physcia leptalea, for instance. South Karelia provides only five additional taxa to this “southern” or southwestern element. A few marine species have their area extended along the coastal provinces of Gulf of Bothnia until Satakunta (Ramalina siliquosa) and South Ostrobothnia (so e.g. Anaptychia ciliaris var. melanosticta and Physcia tenella var. marina) or even to Outer Ostrobothnia like Caloplaca scopularis. A western pattern is represented also by Cladonia strepsilis, Lecanora intumescens, Ramalina baltica and R. subfarinacea, but these species extend their ranges farther off inland. The reverse, an eastern distribution pattern is less obvious but may be seen in the ranges of e.g. Hypocenomyce anthracophila, Menegazzia terebrata and Tuckermannopsis ciliaris. A major decrease in the number of “southern” species takes place in the inland province South Häme with its great number of “endemics”, so that 18 % of the total number of taxa have not been recorded north of this province. A notable decline of 5.1 % after Outer Ostrobothnia and of 7.7 % after Koillismaa, with additional decrease in Kittilä and Sompio Lapland, results in that ca. 50 % of the species have not been recorded in the northernmost provinces Enontekiö and Inari Lapland. The province Åland (A) shares some 91 % of its taxa with Varsinais-Suomi (V), whereas some 39,4 % of the taxa present in V have not been recorded from A. This may partly be explained by the different size and digressing natural conditions of these areas but is more likely due to the less intense of study of Åland lichens, which is also seen in the lower figure of taxa recorded in this province and the relatively high number of taxa recorded in V only. Comparison of the records of Åland – representing the hemiboreal zone – with some other areas shows that this province shares 63 % of its taxa with Koillismaa, in the northern boreal zone, and 50 % of its species are also found in Enontekiö Lapland or some 52.5 % in Inari 152 Folia Cryptog. Estonica Lapland, these two northernmost provinces representing orohemiarctic and even oroarctic areas. 46 % of the species found in VarsinaisSuomi are shared with Inari Lapland, respectively; however, the number of species shared by Varsinais-Suomi and Inari Lapland is higher than in the case of Åland because of the higher number of species found in Varsinais-Suomi. the areas of research by taxonomists like William Nylander, Edvard Vainio and Veli Räsänen: South Häme leading with 174 described taxa, of which 104 are “accepted”, then Uusimaa (59 v. 24 taxa, respectively), Varsinais-Suomi (43 v. 17), Inari Lapland (38 v. 22), Outer Ostrobothnia (31 v. 9), Enontekiö Lapland (30 v. 15) and Koillismaa (29 v. 24). Northern pattern of range Not surprisingly, E. Acharius stands as the describing author of some 200 accepted taxa, but the most proliferous author proves to be W. Nylander (some 260 taxa plus about ten taxa validated by others but credited to Nylander). Next comes E. Vainio with about 100 taxa, then C. von Linné, who has named the epithet of 92 taxa, and Th. Fries, with 55 taxa. These five Nordic authors have described 43.7 % of the lichens and allied fungi of Finland. As to the “northern” element, species only recorded in the two northernmost provinces Enontekiö and Inari Lapland comprise 8 % of the total (19 % for vascular plants, see Lahti et al., 1988). For example, Dactylina ramulosa, Lecanora frustulosa, Solorina bispora and S. octospora are known only in Enontekiö Lapland, and Siphula ceratites only in Inari Lapland, whereas Lobaria linita, Rhizoplaca chrysophthalma, R. melanophthalma and Stereocaulon spathuliferum have been recorded in both. 14 % of the lichens of Finland have not been found south of Koillismaa (15 % of vascular plants!). The respective figure for Middle Ostrobothnia – in the middle boreal zone – is 18.2 %, for South Ostrobothnia 23 %, and 1/3 of the taxa have their total recorded range in or north of South Häme. Who described the Finnish lichens? An attempt was made in the checklist to indicate, if the nomenclatural type of a taxon was known to be from a Finnish province. At least 257 accepted taxa (15.6 %) and 284 additional synonymous names have their type from Finland, these listings certainly not being complete. The highest numbers of types emerge in those biogeographical provinces, where floristic activity on lichens has been intensive, and display REFERENCES Lahti, T., Kurtto, A. & Väisänen, R. A. 1988.

INTRODUCTION Although about 38 local lichen floras have been studied from the Taimyr Peninsula and neighbouring islands (Zhurbenko 1996), lichens of its southern tundras have been heretofore much neglected. Lichens of southern tundras of Taimyr have been specially treated only by T. Piin (1984). There is also some information about dominant lichens from southern tundras in a few geobotanical papers (Avramchik, 1937; Alexandrova, 1937; Matveeva & Zanokha, 1986; Pospelova, 1974; Tyulina, 1937; Vinogradova, 1937). The present paper is a further contribution to the lichen flora of the area. It is a pleasure to include it in a festschrift of Prof. Hans Trass, an outstanding representative of Estonian lichenology, who has contributed much to the knowledge of Taimyr lichens. From 16 till 24 July 1983, the author collected lichens near the field research station "Belyi Yar" of the Norilsk Far North Agricultural Research Institute (70º05’N, 87º43’E). The study area is located between the northern extremity of Pyasino Lake, west of the mouth of the Pyasina River and Ladanakh and Polovinnoe Lakes (Fig. 1). It is part of the northern Siberian Lowland. The landscape is hilly plain with numerous lakes and moraine deposits, like low crests and boulder fields. Altitudes range from 30 to 150 m. The region is situated within the zone of continuous permafrost and is influenced by the continental Siberian climate (Atlas of the Arctic, 1985). Mean annual temperature is approximately -12ºC with the lowest mean monthly temperature approximately -30ºC in January and the highest, +12ºC in July. The daily mean is above freezing from the beginning of June up to the middle of September. Annual precipitation is about 300-400 mm. The dominant vegetation is classified as southern or shrub tundra (Chernov & Matveeva, 1979) and is characterized by closed shrub vegetation in upland tundras. Here and there vegetation cover includes areas of forest tundras with Larix sibirica Ledeb., typical tundras, meadows, and bogs. Frequently dominating species are Alnus fruticosa Rupr., Betula nana L., Salix lanata L., S. reptans Rupr., S. pulchra Cham., S. glauca L., Dryas octopetala L., Vaccinium uliginosum L., V. vitisidaea L., Cassiope tetragona (L.)

(Matveeva & Zanokha, 1986). MATERIAL AND METHODS Lichens were collected at 19 sample plots, representing the following nine habitat types (their numbers are cited in the list of taxa). 1 – exposed windswept areas of prominent convexities; spotty lichen-bryophyte-dwarfshrub communities. 2 – slopes of terraces of Pyasino Lake in places with open boulder fields; shrubs (Alnus fruticosa, Betula nana), meadow tundras. 3 – slopes of moraine crests and lake terraces in places with boulder fields; lichen-bryophytedwarf-shrub communities. 4 – shore of Pyasino Lake; shrubs (Alnus fruticosa, Betula nana ). 5 – plain and gentle slopes; tussock and spotty tundras. 6 – swampy plain with peat hillocks; lichendwarf-shrub-bryophyte communities. 7 – shores of lakes and streams with open sand and pebbles. 8 – lower slopes of lake depressions; willow shrubs. 9 – boulder beds on lower slopes of lake depressions. Standard TLC methods were used for identification of some specimens of Cladonia and Peltigera. Voucher specimens are deposited in LE and H. RESULTS AND DISCUSSION The study resulted in a list of 152 species of lichens and 15 species of lichenicolous fungi which are representative for a typical local flora of southern tundras of Taimyr. All lichen species fall into wide-ranging circumpolar arctic-alpine, arcto-boreal, or boreal distributional categories. 155 The list is no doubt incomplete, for instance a nearby local flora from the vicinities of settlement Kresty Taimyrskie numbers 178 species just of epigaeic lichens (Piin, 1984). Recently a few publications summarizing knowledge on lichens and lichenicolous fungi of the Russian Arctic have been published. Andreev et al. (1996) report 1069 species of lichens and nine species of lichenicolous fungi for the Russian Arctic as a whole. Zhurbenko & Santesson (1996) report 74 species of lichenicolous fungi for the Russian Arctic, and Zhurbenko (1996) reports 660 species of lichens and 61 species of lichenicolous fungi for the north of Central Siberia. To these lists we can now add 20 species. Bachmanniomyces uncialicola, Bispora christiansenii, Epicladonia sandstedei, and Taeniolella pertusariicola are new to Russia; Acarospora nitrophila, Lecanora chlarotera, Pilophorus dovrensis, and Protoparmelia picea are new to the Russian Arctic; Buellia epigaea, Dactylospora attendenda, Lecanora leptacina, Pertusaria carneopallida, Polyblastia fuscoargillacea, Sagediopsis campsteriana, and Taeniolella beschiana are new to the north of Central Siberia; Amygdalaria elegantior, A. panaeola, Bacidia herbarum, Lecania cyrtella, Rinodina archaea, and R. lecideoides are new to Taimyr. Dactylospora purpurascens is reported for the second time for Russia.
