An annotated checklist of the Ceramiales (Rhodophyceae; red algae) of the Mediterranean, based on literature
records, is given. The distribution of each taxon in the area (which is divided into 16 regions) is reported.
The number of species and infraspecific taxa of this group accepted for the Mediterranean Sea as currently
recognised taxonomically is 271. This list has benefited from the suggestions on taxonomy, nomenclature and
regional distribution made by phycological advisers for each region.
Introduction
This checklist of Mediterranean seaweeds is intended
to be a catalogue of benthic algal taxa of the Mediterranean Sea, including the Rhodophyceae s.l., Fucophyceae (Phaeophyceae) and Chlorophyceae s.l. The
Fucophyceae were treated in the first part (Ribera et
al. 1992) while the Chlorophyceae s.l in the second
(Gallardo et al. 1993). The Rhodophyceae will be
compiled in three parts, the first of which includes
the Ceramiales. The number of specific and infraspecific taxa of this order accepted for the Mediterranean Sea under current taxonomy is 270.
This list has been compiled following the scheme
used in the first part of this series (Ribera et al. 1992).
The area has been split into 16 regions (Fig. 1) that
Fig. 1. Geographical regions included: (Sp) Spain, (BI) Balearic Islands, (Fr) France, (CS) Corsica and Sardinia, (WI)
Western Italy, (Si) Sicily and adjacent islands (including Gulf of Taranto), (Ad) Adriatic Sea (including Albania), (Gr)
Greece, (BS) Black and Azov Seas, (Tu) Turkey (Marmara Sea and Mediterranean coast), (LS) Levant States (Syria,
Lebanon and Israel), (Eg) Egypt, (Li) Libya, (Tn) Tunisia, (Ag) Algeria, (Mo) Morocco.

are labelled with two-letter symbols in the following
manner: (Sp) Spain, (BI) Balearic Islands, (Fr)
France, (CS) Corsica and Sardinia, (WI) Western Italy, (Si) Sicily and adjacent Islands (including the
Gulf of Taranto), (Ad) Adriatic Sea (including Albania), (Gr) Greece, (BS) Black and Azov Seas, (Tu)
Turkey (Marmara Sea and Mediterranean coast),
(LS) Levant States (Syria, Lebanon and Israel), (Eg)
Egypt, (Li) Libya, (Tn) Tunisia, (Ag) Algeria, (Mo)
Morocco.
This work benefited from the suggestions on taxonomy, nomenclature and regional distribution of an
advisory board of phycologists. The advisers were:
B. Antolic (Ad), V. Aysel (Tu, BS), A. Bavaru (BS),
A. Bologa (BS), S. Cirik (Tu), A. Diapoulis (Gr),
R. Einab (LS) and S. Haritonidis (Gr).
References used for the areas are given in Table I.
Taxa are named with their nomenclatural authorities;
the names have been abbreviated following Brummitt
and Powell (1992). The families are systematically arranged, according to Maggs and Hommersand
(1993), while genera, species and infraspecific taxa
are arranged alphabetically. Both in the list of taxa
and in the index, names of accepted taxa are in italics
whereas synonyms, misapplied names and doubtful
or unaccepted taxa are in roman type. When a specific or infraspecific taxon has definitely been recorded for a geographical area, the number corresponding to the bibliographic reference utilized is
cited in the list. Because of space limitation, only one
reference is cited for each area, but additional references are available from the authors on request. Abbreviations of journals follow those of B. P. H. (Lawrence et al. 1968). When a name of a specific or infraspecific taxon has been recorded as a synonym or
misapplied name, the reference number in the list is
in italics, while the synonym or misapplied name is
given in roman type below the current name. Superscript numbers refer to notes.
A list of proposed nomenclatural changes, of nomina nuda, of taxa excludenda, as well as a list of
taxa inquirenda is also given.

We follow Athanasiadis (1987: 70) in considering Aglaothamnion neglectum as a synonym of A. cordatum; Silva
et al. (1996) in the Indian Ocean listed them as distinct
species.
We follow Maggs and Hommersand (1993) in referring
to this species citations under Aglaothamnion brodiaei
and Callithamnion brodiaei, based on Feldmann-Mazoyer’s concept of A. brodiei (‘brodiaei’).
Aglaothamnion hookeri is a northern species recorded
from Norway to the north of France (Maggs and Hommersand 1993) although Price et al. (1986) recorded it
(Callithamnion hookeri) from tropical West Africa. The
presence of this species in the Mediterranean Sea needs
to be confirmed.
Some authors, following Dixon and Price (1981), such
as Price et al. (1986) and Athanasiadis (1987), consider
A. scopulorum to be heterotypic synonym of A. hookeri.
Conversely, we follow Coppejans and Kling (1995) in
considering the two species as distinct.
In accordance with Furnari et al. (1998), Mediterranean
citations of Aglaothamnion tenuissimum var. tenuissimum
sensu Feldmann-Mazoyer are referred to A. tenuissimum
var. mazoyerae.
Giaccone (1978: 58, 66) cited both Aglaothamnion furcellariae and Seirospora byssoides, which are synonyms of
Aglaothamnion tenuissimum var. tenuissimum.
As Callithamnion decompositum J. Agardh (see Taxa excludenda).
We refer to Anotrichium furcellatum records of Griffithsia
arachnoidea C. Agardh (Si 83) since the two taxa have
been generally considered conspecific. However, as
pointed out by Maggs and Hommersand (1993:183) G.
arachnoidea was based on two specimens one referable
to Halurus flosculosus (J. Ellis) Maggs et Hommers., but
the other is difficult to identify, but is not referable to A.
furcellatum.
In accordance with Athanasiadis (1996 a) we do not recognise infraspecific categories. This species includes var.
cruciatum f. radicans Feldm.- Maz. (Sp 35, CS 48, Si 124,
BS 246, Tu 17), var. profundum Feldm.- Maz. (Sp 20, BI
200, Fr 50, CS 84, WI 121, Si 124, Ad, 123, Tu 97, Tn
31), var. profundum f. radicans Feldm.- Maz. (Si 82) and
var. pumilum (Harv.) Nägeli (Sp 20).
Mediterranean citations of A. antillanum Børgesen are
probably misidentifications of A. decipiens (see Verlaque
1990; Athanasiadis 1996 a). Accordingly, records of A.
antillanum are placed here under A. decipiens. This species
is also cited from Ad 123 and Gr 10 as A. cruciatum var.
cruciatum f. fragilissimum ‘fragilissima’ (Zanardini)
Hauck.
According to Athanasiadis (1996 a) this taxon is a synonym of A. sublittoralis (Setch. et Gardner) Athanas.
This species was recorded before 1950 (Feldmann-Mazoyer 1941: 341) but not mentioned later; its presence in
Fr needs to be confirmed.
Ceramium bertholdii has been mentioned from Alexandria by Nasr and Aleem (1949: 277). However, Aleem
(1993) did not include this species, probably considering
his earlier citation as a misidentification.
The occurrence of this boreal taxon in the Mediterranean
Sea should be confirmed.
Some records are as f. ‘flaccida’.
This species includes var. confluens (Kütz.) Ardiss. (Ad
123), var. densecorticatum Woron. (BS 27) and var.
transcurrens (Kütz.) Schiffn. (Ad 123).

This species is also cited from Ad 102 as Ceramothamnion adriaticum Schill.
All records are as ‘deslongchampii.’ According to Maggs
and Hommersand (1993), followed also by Silva et al.
(1996), C. strictum (Kütz.) Rabenh. nom. illeg. (and consequently C. diaphanum var. strictum) is conspecific with
C. deslongchampsii. Both species have the same pattern
of cortication and their apices are either straight or incurved (Maggs and Hommersand 1993: 52 and Feldmann-Mazoyer 1941: 309). We tentatively refer to this
taxon the records from Sp 20, Si 83, and Gr 10 as C.
strictum Harv., that from BS 246 as C. strictum Grev. et
Harv. and that from Tu 245 as C. strictum (Kütz.) Feldmann, since it is unlikely that they refer to C. strictum
sensu Harv. as circumscribed by Maggs and Hommersand (1993).
This species is also cited from BS 149 as Ceramium corticatulum Kylin.
Literature records are difficult to assess owing to taxonomic confusion. However, taking in consideration that
most Mediterranean citations of C. diaphanum var. diaphanum were based upon Feldmann-Mazoyer’s (1941)
concept, i. e., on Harvey’s specimens and illustration,
they are placed here under C. siliquosum (see Maggs and
Hommersand 1993).
This species is also cited in Ad 123 as C. pygmaeum
(Kütz.) Schiffn. C. pygmaeum is a nom. illeg. being a
later homonym of C. pygmaeum (Kütz.) Ardiss. 5 C.
diaphanum (Lightf.) Roth.
This species includes var. mediterraneum Feldm.-Maz.
Ballesteros (1990: 21) cited both Ceramium flaccidum
and C. taylorii E. Y. Dawson, which are synonyms.
The record of Di Martino and Giaccone (1996) from FR
is considered doubtful by Verlaque and Bernard (1998).
Reported as C. flabelligerum in Gr, but placed among
species excludenda by Athanasiadis (1987: 78).
Ceramium giacconei was described by Cormaci and
Furnari (1991 b) to accommodate Mediterranean citations of C. cingulatum. Accordingly, all the citations of
the latter are considered as misidentifications and transferred here to C. giacconei.
According to Cormaci et al. (1995), this species is distinct
from C. codii in the pattern of cortication (in C. incospicuum each pericentral cell cut off obliquely two acropetal and two basipetal cells, while in C. codii no basipetal
cells are produced) and in the apices (in C. incospicuum apices have even outlines, while in C. codii apices are not
even).
The taxonomic status of Ceramium petitii requires further investigation.
Silva et al. (1996) pointed out that Ceramium nodulosum
(Lighf.) Ducluz., the name proposed by Maggs and
Hommersand (1993) for the species commonly reported
as Ceramium rubrum (Huds.) C. Agardh, cannot be used.
We here follow Silva et al. (1996), who proposed to conserve Ceramium rubrum auctorum, as provided by
Art. 14.1 and 14.9 of the ICBN (Greuter et al. 2000).
Ceramium rubrum f. decurrens (J. Agardh) Kjellm., from
the original description, can be considered as synonym
of C. rubrum var. rubrum.
Zinova (1967: 2902295) cited also Ceramium arborescens
J. Agardh and C. pedicellatum (J. Agardh) J. Agardh
(nom. illeg.), which are synonyms of C. rubrum. The possible synonymy between C. arborescens and C. rubrum is
proposed by Garbary et al. (1978) and is accepted by

Nielsen et al. (1995). This species is also cited from BS
94 as C. areschougii Kylin that according to Nielsen et
al. (1995) is synonym of C. rubrum.
We follow Abdelahad and D’Archino (1998) in referring
to Mediterranean records of C. rubrum var. barbatum
(Kütz.) J. Agardh as well as of C. nodulosum var. barbatum to C. secundatum. The records of Sp 65, Mo 133 are
cited as C. nodulosum var. barbatum and the records BI
193, Fr 50, CS 84, WI 121, Si 124, Ad 123, Tu 14, Eg 8,
Tn 31 and Ag 183 are cited as C. rubrum var. barbatum.
Literature records are difficult to assess owing to taxonomic confusion. However, taking into account that
most Mediterranean citations of C. diaphanum var. diaphanum were based upon Feldmann-Mazoyer’s (1941)
concept, i. e., on Harvey’s specimens and illustration,
they are placed here under C. siliquosum (see Maggs and
Hommersand 1993). The records from Sp 20, BI 193, Fr
50, CS 48, Gr 10, BS 246, TU 15, LS 167, EG 8, Tn 31,
Ag 183 are as C. diaphanum var. diaphanum.
This taxon is cited also in Ad 123 as Ceramium orthocladum Schiffn. and as C. diaphanum var. decipiens Schiffn.
This species was recorded before 1950 (Ollivier 1929, as
C. elegans) and not mentioned later; its presence in Fr
needs to be confirmed.
According to Womersley (1978: 234), it is uncertain that
the Mediterranean material ascribed to this species by
Mazoyer (1938: 324), Feldmann-Mazoyer (1941:
2892293) and further Mediterranean authors is identical
with the Japanese C. tenerrimum.
For nomenclatural problems dealing with this genus and
species, see Athanasiadis (1996 b: 104, footnote 226).
This species was recorded before 1950 (Decrock 1914)
and not mentioned later; its presence in Fr needs to be
confirmed.
Giaccone et al. (1986: 6502651) cited both Centroceras
pignattii Giaccone and Ceramium cinnabarinum which
are synonyms of Corallophila cinnabarina.
Giaccone (1978: 64) cited also var. maior Erceg. which
can be considered as a synonym of the autonym.
The genus Pseudocrouania was created by Funk (1955)
based on P. ischiana. Both the species and the genus were
poorly described. Pseudocrouania was distinguished from
Crouania on the basis of the tetrahedral (instead of cruciate) cleavage of tetrasporangia. In addition, Funk (1955)
mentioned four whorl branchlets per axial cell, but he
did not emphasize this feature, which should be of major
importance, if correct (only three whorl branchlets exist
in Crouania). Mayhoub (1976: 1722173), who examined
the type material, a single slide in poor condition (this
slide is lost at present; Buia, personal communication to
G. Furnari), did not assess the number of whorl branchlets. In fact, further authors assigned to this species specimens with three whorl branchlets (Coppejans 1983: pl.
188). As far as the division of tetrasporangia is concerned, this criterion does not seem to have a high taxonomic value (Mayhoub 1976) although the tetrahedral
cleavage of tetrasporangia appears to be a constant feature in material collected at the type locality, Castello
Aragonese, Ischia Island (Boudouresque and Cinelli
1971: 11). Coppejans (1983: pls 1872189) pointed out
additional differences with C. attenuata: diameter of the
axes and shape of the apices. Although the specific status
of this taxon remains unclear and requires taxonomic
reinvestigation, it appears to be better accommodated
within the genus Crouania.

Reported in Ag by Perret-Boudouresque and Seridi

Ercegović (1980) cited both Griffithsia flosculosa (J. Ellis)
Rupr. and Griffithsia setacea (Huds.) C. Agardh which
are synonyms.
This taxon has been thoroughly revised by Athanasiadis
(1996 a). Accordingly, its geographical distribution in the
Mediterranean, based on previous citations, should be
considered with caution and requires further investigation.
Boudouresque et al. (1984: 49) cited both Platythamnion
plumula var. crispum and var. bebbii which are synonyms
of Pterothamnion crispum. Boudouresque et al. (1977)
proposed the new combination ‘Platythamnion plumula
(Ellis) comb. nov. var. bebbii (Reinsch) Feldmann’. Such
a combination, which should be attributed to Boudouresque et al., is invalid since the basionym was not
cited directly as required by the ICBN.
Cited from Tu 17 as Platythamnion plumula (Ellis) Boudour. et al. var. crispum (Ducluz.) Hauck comb. inval.
This taxon has been thoroughly revised by Athanasiadis
(1996 a). Accordingly, its geographical distribution in the
Mediterranean, based on previous citations, should be
considered with caution and requires further investigation.
According to Maggs and Hommersand (1993), Spermothamnion barbatum (Si 82, Tn 31, Ag 183) is a synonym
of Ptilothamnion pluma.
Giaccone (1978: 66) cited both Ptilothamnion pluma and
P. micropterum (Mont.) Bornet which are synonyms.
Species recorded before 1950 (Feldmann-Mazoyer 1941:
443) and not mentioned later. The presence of this species in Fr needs to be confirmed.
Giaccone et al. (1986: 665) cited both Seirospora interrupta and S. seirosperma (Harv.) Dixon, which are
synonyms.
Giaccone (1978: 67) cited both Seirospora interrupta and
S. griffithsiana Harv. which are synonyms.
This species includes var. subtilissima (De Not.) De Toni
(BS 246).
Some records are as f. ‘dispora’.
This species includes var. turneri (Mertens) Rosenv. (Sp
20, Si 124, Ad 123).
Some records are as f. ‘disticha’.
This species is also cited from Tu 14 as Spyridia villosiuscula Kütz.
Species recorded before 1950 (Raphelis, 1907 as S. aculeata) and not mentioned later. The presence of this species in Fr needs to be confirmed.
The record is as ‘feldmannae’.
A second species of Acrosorium, A. reptans (P. Crouan et
H. Crouan) Kylin [5 A. uncinatum (Turner) Kylin var.
reptans (P. Crouan et H. Crouan) Boudouresque et al.] is
also recorded from the Mediterranean Sea. However, the
type of its basionym Nitophyllum reptans P. Crouan et
H. Crouan is regarded by Wynne (1989) as a prostrate
growth form of Cryptopleura ramosa. Since prostrate
young blades of C. ramosa cannot easily be separated,
morphologically, from those of Acrosorium venulosum
(see Maggs and Hommersand 1993: 257), it is highly
probable that most Mediterranean citations of A. reptans
are misidentifications of A. venulosum and therefore they
have not been taken into consideration here.
According to Wynne (1989) the intended basionym of
this taxon (Fucus laceratus var. uncinatus Turner) is refer-

able to Cryptopleura ramosa, while records from Britain
and Ireland of A. uncinatum should be referred to A.
venulosum. We think that the same is true for Mediterranean records of taxa with the specific or infraspecific
epithet ‘uncinatum’.
The taxonomic status of this species and its generic position require further investigations (sexual reproductive
structures are unknown).
This species is also reported from Ad 170 as Nitophyllum
vidovichii (Menegh.) Hauck.
The record from Mo 133 as Cottoniella filamentosa var.
filamentosa should correspond to the var. algeriensis because the latter variety has been recorded from Alboran
Island (near Morocco) and Algeria.
The record of Hypoglossum hypoglossoides [var. hypoglossoides] f. profundum (Erceg.) Span et Antolic comb.
inval. (since the basionym was not cited directly as required by the ICBN) is included. Additionally, H.
woodwardii var. angustifolium (‘angustifolia’) Kütz. (BS
16, Tu 17) and var. penicillatum (‘penicillata’) (Zanardini)
De Toni (Ad 123) are also included.
Mediterranean species of this genus are of doubtful taxonomic position, because their plastid morphology does
not correspond with that of the genus Myriogramme
(Kylin 1924; Hommersand and Fredericq 1997 a,b)
Therefore, in the absence of fertile specimens the taxonomic position of these species remains uncertain.
Due to the production of tetrasporangial sori directly on
primary blades, as reported in Nitophyllum carneum J. J.
Rodr. (Rodrı́guez Femenias 1889), the species falls within
the circumscription of the genus Myriogramme Kylin.
Barceló i Martı́ (1987) referred to M. carnea some sterile
specimens, collected at Alicante (Spain), having a simple
parietal, plate-like, plastid per cell. However, the occurrence of this character, if confirmed, could question the
maintenance of the species in the genus Myriogramme.
From a nomenclatural point of view, even though in the
title of his paper Boudouresque (1971 a) quoted this species as M. distromatica (Rodrı́guez) comb. nov., but since
Nitophyllum distromaticum J. J. Rodr. is a nomen nudum,
Boudouresque made a description of a new species
rather than a new combination. According to Art. 37.2
of ICBN (Greuter et al., 2000), the species was validly
described since Boudouresque indicated as holotype two
specimens, collected by Rodrı́guez Femenias, which are
part of a single gathering. The species shows a single
parietal, plate-like, fenestrate plastid per cell, and therefore does not fall within the circumscription of the genus
Myriogramme.
According to Wynne (1994) the transfer of Myriogramme
minuta Kylin to the genus Drachiella by Maggs and
Hommersand (1993: 236) appears rather tenuous ‘…in
that tetrasporangial sori are produced directly on the primary blade in M. minuta, not in special proliferations.
This character typically serves to separate genera in this
family…’. Further studies are clearly required.
Funk (1955: 1052106) combined his Nitophyllum gaiolae
under the genus Myriogramme as Myriogramme gaiolae
(Funk) Funk. The criteria upon which he based the distinction of his species from M. minuta are of poor taxonomic value; it seems to fall well within the range of
variation of M. minuta. Accordingly, we consider M. gaiolae as an heterotypic synonym of M. minuta.
Funk (1955: 1052106) cited Myriogramme minuta and
M. gaiolae from WI.

A. Gómez Garreta et al.
González Garcı́a and Conde Poyales (1994) cite both
Myriogramme minuta and M. gaiolae from Mo.
Since the species shows a single parietal, plate-like plastid per cell (Furnari et al. 1999 and Boudouresque, unpublished observations), it does not fall within the circumscription either of the genus Nitophyllum or of the
genus Myriogramme. Furnari et al. (1999) recorded this
species from the Adriatic Sea, as Nitophyllum tristromaticum Rodrı́guez ex Mazza, remarking that ‘Boudouresque in Boudouresque et al. (1984:49) combined
this species under the genus Myriogramme as M. tristomatica (J. J. Rodr. ex Mazza) Boudouresque but providing not taxonomic reasons’.
This species includes var. ocellatum (Lamour.) Harv. (Si
124, Ad 123, BS 16, Tu 17) and var. lobatum Funk (WI
113). According to art. 36.2 of ICBN (Greuter et al.,
2000) the name of the last taxon is illegitimate since a
Latin diagnosis was not given at the time of publication.
This species was described by Kylin (1924) (as Rhizoglossum adriaticum) from the Adriatic, but it has not been
recorded subsequently from there.
Dasya arbuscula (Brown ex Dilwyn) C. Agardh is a taxonomic synonym of Aglaothamnion sepositum (Gunnerus)
Maggs et Hommers. since its basionym Conferva arbuscula Brown ex Dilwyn belongs to the genus Aglaothamnion (Dixon 1960; Maggs and Hommersand 1993). However, we refer to D. hutchinsiae all records of D. arbuscula
from the Mediterranean Sea thinking that they fall
within Harvey’s (1849: pl 224) taxonomic concept of the
species (D. arbuscula sensu Harvey).
De Toni (1903) treated D. rigescens Zanardini as a form
of D. ocellata: D. ocellata f. rigescens (Zanardini) De
Toni, but, according to Verlaque (pers. comm.) D. rigescens is a distinct species differing from D. ocellata in having stichidia borne on axes (borne on branchlets in D.
ocellata).
Athanasiadis (1987: 85) included, with doubt, this taxon
among the synonyms of D. hutchinsiae.
Giaccone et al. (1986: 675) cited both Dasya rigidula and
D. squarrosa (Kütz.) Rabenh. which are synonyms.
According to Jong et al. (1997) Eupogodon cervicornis is
conspecific with E. spinellus.
Many records are as either ‘Halodyction’ or ‘Halodictyon’.
The presence of this species in the Mediterranean Sea
requires confirmation.
The presence of this species in the Mediterranean Sea
requires confirmation. If this was the case, some citations of Acanthophora should be critically re-examined.
All records are as ‘najadiformis’.
Aysel (1997: 162) reported both Alsidium corallinum and
A. lanciferum Kütz. which are synonyms.
McIvor et al. (1999), on the basis of sequence data, indicated that Boergeseniella cannot be supported as separate genus from Polysiphonia.
This species includes var. wulfenii Bornet (WI 122, Si 124,
Ad 123).
This species was recorded before 1950 (Raphelis, 1907,
as Polysiphonia thuyoides) but not mentioned later; its
presence in Fr requires confirmation.
This species includes Chondria tenuissima var. uncinata
(Zanardini) De Toni (Ad 123) and f. divergens (J.
Agardh) Hauck. (BS 27, Tu 17).
The presence of this species in the Mediterranean Sea

the record from Greece (only one sterile specimen) may
be referable to C. curvilineata.
According to Boudouresque and Perret-Boudouresque
(1987) this species may possibly represent dwarf but fertile specimens of C. capillaris (as C. tenuissima).
The genus name is treated as masculine according to
Art. 62.2 c of (Greuter et al. ICBN 2000)
Laurencia paniculata (C. Agardh) J. Agardh is an illegitimate name since it is a later homonym of L. paniculata
Kütz., which probably corresponds to Osmundea truncata. Since the species (as of L. paniculata) was generally
considered a synonym of L. glandulifera, all records but
those from CS and Gr that according to Boisset et al.
(2000) are based on specimens belonging to this taxon
should be checked from a taxonomic point of view.
Species recorded before 1950 (Ollivier 1929: 145) and
not mentioned later. The presence of this species in Fr
needs to be confirmed.
All records are as ‘incurvus’.
A revision using recent taxonomic criteria is required in
order to ascertain if L. caspica belongs to the genus
Laurencia or to one of the two related genera Chondrophycus and Osmundea.
A revision using recent taxonomic criteria is required in
order to ascertain if L. coronopus belongs to the genus
Laurencia or to one of the two related genera Chondrophycus and Osmundea.
Verlaque and Bernard (1998) considered the record
from Fr 93 as doubtful.
Records of Laurencia obtusa var. crucifera Kütz. (WI
121, Ad 123, Gr 10, BS 16) and var. gracilis (C. Agardh)
Zanardini (Fr 73, BS 16, Tu 15, Li 132) are included.
Both taxa were considered as synonyms of L. obtusa
var. gelatinosa (J. V. Lamour.) J. Agardh by Børgesen
(1918) and by J. Agardh (1852, as Chondria obtusa var.
gracilis), respectively. Laurencia obtusa var. gelatinosa
was later considered by Taylor (1967) to be a synonym
of L. microcladia. However, if the conspecificity between L. gelatinosa J. V. Lamouroux (1813) and L.
microcladia Kützing (1865) was confirmed, the species
should be named L. gelatinosa since Lamouroux’s epithet predates that of Kützing.
Even though Silva et al. (1996) treated L. oophora Kütz.
as a distinct species, we follow Yamada (1931) in considering this taxon, recorded from LI (132), a synonym
of L. obtusa.
Furnari et al. (2001) included Laurencia obtusa var. pulvinata Feldmann (Fr 50, BS 27, Ag 183) among the heterotypic synonyms of L. obtusa.
A revision using recent taxonomic criteria is required.
Two species of the genus Lophocladia have been recorded from the Mediterranean Sea: L. lallemandii and
L. trichoclados. They appear to differ from each other
mainly in the branching pattern with secondary axes
replacing trichoblasts or formed in axil of trichoblasts
in the former and in the latter species, respectively. Boudouresque and Verlaque (1976) described specimens
from Corsica showing secondary axes formed in axil of
trichoblasts; but, since their specimens differ from L.
trichoclados in other minor morphological characters,
they referred them, with doubt, to that species. Conversely, Patzner (1999) records from Ibiza (BI) L. lallemandii with doubt. Balearic specimens show both
branching patterns (L. Lavelli, pers. comm.), which
questions the distinction of the two species or, at least,

the taxonomic validity of this character to separate

Lophosiphonia obscura is a species with 527 pericentral
cells. In fact, this name has been largely misapplied to
specimens with a larger number of pericentral cells,
which actually belong to L. reptabunda (see Silva et al.
1996: 9212922). As a result, the geographical distribution of L. obscura that we present here, based upon the
Mediterranean literature, must be considered cautiously.
This species is also cited from BI 193 as Lophosiphonia
subadunca (Kütz.) Falkenb. and Polysiphonia barbatula
Kütz.
This species is also cited from Ad 123 as Lophosiphonia
subadunca and Lophosiphonia intricata Schiffn.
Laurencia pelagiensis Cormaci et al. is a nom. inval. according to Art. 34.1 of ICBN (Greuter et al. 2000).
On the basis of the paper by Furnari and Serio (1993),
Mediterranean records of L. pinnatifida (5 Osmundea
pinnatifida (Huds.) Stack.) should be referred to as
Laurencia truncata Kütz. (5 Osmundea truncata (Kütz.)
K. W. Nam et Maggs). The only presence of L. pinnatifida in the Mediterranean (as O. pinnatifida) is from Mo
39.
Giaccone (1978: 73274) cited both Laurencia pinnatifida (a misapplied name for O. truncata) and L. truncata
(5 O. truncata). Furnari et al. (1999: 54) cited Osmundea ramosissima (Oeder) Athanas., a misapplied name
for O. truncata, since Nam et al. demonstrated that O.
ramosissima is distinct from O. truncata and that only
the latter species is confirmed to occur in the Mediterranean Sea.
Laurencia verlaquei Cormaci et al. is a nom. inval. according to Art. 34.1 of ICBN (Greuter et al. 2000).
Species recorded before 1950 (Preda 1908) and not mentioned later. The presence of this species in Fr and WI
needs to be confirmed.
The conspecificity between Dasya corallicola Funk
(1927) and Polysiphonia biformis is based on a later
statement of Funk (1961) confirmed by a recent examination of Funk’s original material made by G. Furnari
(unpublished data).
According to De Toni (1903: 916), P. biformis is a synonym of Polysiphonia flexella (C. Agardh) J. Agardh.
Giaccone et al. (1986: 673, 687) cited both Dasya
corallicola and Polysiphonia biformis.
Ercegović (1980: 39, 40) cited both Dasya corallicola
and Polysiphonia biformis.
This species was recorded before 1950 (Preda 1908) and
not mentioned later; its presence in Fr requires confirmation.
Some records are as ‘brodiaei’.
This species is also cited from BS 16 as Polysiphonia
variegata and as P. vidovichii Meneghini.
This species is also cited from Tu 14 as Polysiphonia
divergens J. Agardh.
According to Feldmann (1981: 74) Polysiphonia biasolettoana (as ‘biasolettiana’) is a synonym of P. deusta.
This species was recorded before 1950 (Solier 1845) and
not mentioned later; its presence in Fr requires confirmation.

This species includes var. denudata (C. Agardh) J. Agardh (BS 27).
This species is also cited from Sp 65 as Polysiphonia
ruchingeri (C. Agardh) Zanardini.
Mayhoub (1976: 191) recorded this species from Syria
and after his description he pointed out that the genus
Polysiphonia needs to be revised. After checking the description and the illustrations of these specimens we are
of the opinion that they do not correspond to Polysiphonia ferulacea.
This species was recorded before 1950 (Preda 1908; Solier 1845, as Polysiphonia hirta J. Agardh) and not mentioned later; its presence in Fr requires confirmation.
Reported from Gr as Polysiphonia nigrescens and P. violacea (see Athanasiadis 1987: 1042105 among species
excludenda; Haritonidis and Tsekos 1976: 282).
This species is also cited in BS 16 as Polysiphonia aculeata (C. Agardh) Mont. ex De Not.
Reported from Ag as Polysiphonia nigrescens by PerretBoudouresque and Seridi (1989: 84) among species excludenda.
The presence of this species in the Mediterranean Sea
requires confirmation.
Aleem (1993: 1022103) cited both P. opaca and Polysiphonia phleborhiza Kütz., which are synonyms.
This species is also cited from Tu 14 as Polysiphonia
kellneri Zanardini.
This species was recorded before 1950 (Ollivier 1929)
and not mentioned later; its presence in Fr requires confirmation.
This species was recorded before 1950 (Preda 1908, as
P. urceolata) and not mentioned later; its presence in Fr
requires confirmation.
Reported from Gr as Polysiphonia urceolata (see Athanasiadis 1987: 1042105 among species excludenda; Haritonidis and Tsekos 1976: 282).
Maggs and Hommersand (1993: 336) considered Polysiphonia foetidissima Cocks ex Bornet with a note: ’Polysiphonia stuposa Zanardini ex Kütz. (1864, p. 18) predates P. foetidissima, with which it may be conspecific,
although Bornet believed them to be separate; we have
examined type material of this taxon (L 941. 242. 226),
a fragment of the holotype specimen in MEL, which
appears to be very similar to P. foetidissima’.
Giaccone (1978: 76277) cited both P. stuposa and Polysiphonia foetidissima.
We refer to this species the records as Pterosiphonia
spinifera since we think that authors most probably referred to the Mediteranean P. spinifera var. robusta Ardré nom. inval. (5 P. ardreana) and not to the non-Mediterranean taxon P. spinifera var. spinifera.
Ben Maiz et al. (1988: 277) cited both Rodriguezella pinnata and R. pennata Erceg., which are synonyms.
All records are as ‘strafforellii’. Recorded from Ad 100
and Tu 15 as Rodriguezella strafforellii var. crassicaulis
Erceg.
This is the only record of this genus from the Mediterranean Sea. No further information was given about this
taxon.
Nomenclatural changes

A. Gómez Garreta et al.
Maz.) comb. nov. Basionym: Ceramium strictum f.
minusculum (‘minuscula’) G. Mazoyer (Bull. Soc.

[var. zostericola] f. minusculum (‘minuscula’)
(Feldm.-Maz.) Feldm.-Maz.
Feldmann-Mazoyer (1941) reduced Griffithsia
sphaerica Schousb. ex C. Agardh and Griffithsia
irregularis C. Agardh to a varietal rank within the
species Griffithsia flosculosa (J. Ellis) Batters proposing the relative new combinations at pages 422
and 424, respectively. Since Maggs and Hommersand (1993) treated Griffithsia flosculosa as synonym of Halurus flosculosus (J. Ellis) Maggs et
Hommers., the following new combinations are
proposed:
Halurus flosculosus (J. Ellis) Maggs et Hommers. var.
irregularis (C. Agardh) comb. et stat. nov. Basionym: Griffithsia irregularis C. Agardh (Spec. alg.
2: 130, 1828). Homotypic synonym: Griffithsia
flosculosa (J. Ellis) Batters var. irregularis (C. Agardh) Feldm.-Maz.
Halurus flosculosus (J. Ellis) Maggs et Hommers. var.
sphaericus (Schousb. ex C. Agardh) comb. et stat.
nov. Basionym: Griffithsia sphaerica Schousb. ex
C. Agardh (Spec. alg. 2: 130, 1828). Homotypic
synonym: Griffithsia flosculosa (J. Ellis) Batters
var. sphaerica (Schousb. ex C. Agardh) Feldm.Maz.
Nomina nuda
Dasya elegans (G. Martens) C. Agardh var. ramosissima Schiffn.: (Ad 123 as Dasya baillouviana var.
ramosissima Schiffn.)
Microgelidiopsis horrida Erceg.: (Ad 102)
Myriogramme unistromatica Coppejans: (Sp 199, Fr
50, Ad 114). Although illustrated by Coppejans
(1983, pls 2332235), this taxon is a nomen nudum
since requirements of both Art. 36.2 and Art. 37.1
of ICBN (Greuter et al. 2000) were not fulfilled.
It should be noted that, because of the ocurrence
of a single parietal, plate-like, lobed plastid per
cell, Coppejans’ specimens do not seem to fall
within the circumscription of the genus Myriogramme as recently defined by Hommersand and
Fredericq (1997 a,b). In the absence of tetrasporangial and female fertile specimens, the generic
position of this species remains uncertain
Nitophyllum magontanum J. J. Rodr.: (BI 193).
Rodriguezella ligulata Feldmann: (Sp 222, Fr 50, CS
48, Si 124, Ad 123, Tn 31).
Taxa excludenda
Aglaothamnion roseum (Roth) Maggs et L’Hardy-Halos: (FR 88, as Callitamnion roseum Roth). According to Maggs and Hommersand (1993) this is
exclusively an Atlantic species.
Antithamnion antillanum Børgesen: According to
Athanasiadis (1996 a) Mediterranean records of
this species correspond to A. decipiens.
Carpoblepharis ceylanica Harv. ex Kütz.: (Si 220).
Ceramium cingulatum Weber Bosse: We follow Cormaci and Furnari (1991 b) in considering all the
Mediterranean records of this species as misidentifications of C. giacconei.
Chondria oppositiclada E. Y. Dawson: (Li 132).
Chondrophycus intermedius (Yamada) Garbary et
J. Harper (‘intermedia’): (BS 16 as Laurencia intermedia Yamada). The presence of this Japanese species in the Black Sea is very doubtful.
Chondrophycus perforatus (Bory) K. W. Nam (‘perforata’): (Fr 190, Si 130, LS 156) as Laurencia perforata
(Bory) Mont. Since neither descriptions nor illustrations were given in papers where the species is
quoted, and taking into account the taxonomic
complexity of the Laurencia complex, Mediterranean records of this species should be confirmed.
Chondrophycus undulatus (Yamada) Garbary et
J. Harper (‘undulata’): (Fr 44, CS 48, WI 180, Si
124, Tn 31, Ag 183, Mo 133 as Laurencia undulata
Yamada). According to Cormaci et al. (1994),
Mediterranean citations of Chondrophycus undulatus (‘undulata’) (Yamada) Garbary et
J. Harper (Laurencia undulata Yamada) should be
referred to either Laurencia pelagiensis or to L.
verlaquei.
Compsothamnion decompositum (J. Agardh) Maggs et
L’Hardy-Halos: (Sp 20, Gr 10 as Callithamnion decompositum J. Agardh). This species is not present
in the Mediterranean Sea. The records should be
referred to Aglaothamnion tripinnatum (C. Agardh) Feldm.-Maz.
Dasya elongata Sond.: We follow Athanasiadis (1987:
87) in considering this species recorded from Gr
by Giaccone (1968) without any comments, as being incorrectly identified.
Dasya sinicola (Setch. et N. L. Gardner) E. Y. Dawson: (Tu 15). Since neither descriptions nor illustrations were given, the occurrence of this Indo-Pacific species in the Mediterranean Sea should be
confirmed.
Dasya villosa Harv.: The species was recorded from
Gr by Giaccone (1968) without any comments.
Thus, Athanasiadis (1987: 87) considered it as being incorrectly identified. Since the record from Li
by Godeh et al. (1992) is similarly without any
comments, we think that the ocurrence of this Pacific taxon in the Mediteranean Sea requires further study.
Delesseria sanguinea (Huds.) J. V. Lamour.: (Gr 230,
Tu 14).
Drachiella heterocarpa (Chauv. ex Duby) Maggs et
Hommers.: (Si 218 as Nitophyllym versicolor
Harv.).
Griffithsia devoniensis Harv.: (Tu 15). The presence of
this North Atlantic species in the Mediterranean
Sea is very doubtful.
Checklist of Mediterranean seaweeds. III. Rhodophyceae
Haraldiophyllum bonnemaisonii (Kylin) Zinova: (Sp
65). This record is based on Conde (1984: 61) who
considered it doubtful.
Laurencia pyramidalis Bory ex Kütz.: (Sp 65, Si 218
as L. obtusa var. pyramidata J. Agardh, Ad 210 as
L. obtusa var. pyramidata J. Agardh, Gr 140 as L.
obtusa var. pyramidata J. Agardh, Tu 14 as L. obtusa var. pyramidata J. Agardh). Since neither descriptions nor illustrations were given in papers
where the species is quoted, and taking into account the taxonomic complexity of the Laurencia
complex, Mediterranean records of this species
should be confirmed.
Leptosiphonia schousboei (Thur.) Kylin: (Ag 183 as
species excludenda).
Membranoptera alata (Huds.) Stackh.: (Fr 190 as Delesseria angustissima Harv., Si 56 as Hypoglossum
alatum Kütz.).
Osmundea hybrida (DC.) K. W. Nam: (Sp 65, Fr 190
as Laurencia hybrida (DC.) Lenorm. ex Duby, BS
246, Ag 183 as Laurencia hybrida (DC.) Lenorm.
ex Duby. The occurrence of this species in both
the Mediterranean and the Black Seas should be
confirmed by a study of specimens using recent
taxonomic criteria.
Osmundea osmunda (S. G. Gmel.) K. W. Nam et
Maggs: [Si 124 as Laurencia pinnatifida (Huds.)
J. V. Lamour. var. osmunda (S. G. Gmel.) Kütz.].
This record probably refers to O. truncata (Kütz.)
K. W. Nam et Maggs.
Polyneura bonnemaisonii (C. Agardh) Maggs et Hommers.: The only record after 1950 of this species in
the Mediterranean Sea is that of Rindi and Cinelli
(1995: 106) with doubt from Sp. Therefore, the occurrence of this species in the Mediterranean Sea
requires confirmation. This species was recorded
from Fr by Decrock (1914) as Nitophyllum hilliae
Grev.
Polysiphonia fibrata (Dilwyn) Harv.: (Fr 190). According to Maggs and Hommersand (1993) this
is an Atlantic species that in the Mediterranean
Sea could be confused with the closely similar
species Polysiphonia sertularioides (Gratel.) J.
Agardh.
Polysiphonia gorgoniae Harv.: This Red Sea species
was reported from Alexandria, Egypt, as Polysiphonia gorgonia, by Nasr and Aleem (1949: 278)
and Aleem (1951: 252), but was excluded from a
later survey (Aleem 1993).
Polysiphonia lanosa (L.) Tandy: (Fr 88, Ad 123 as
Polysiphonia fastigiata (Roth) Grev., Gr 137). It is
an Atlantic species living exclusively as an epiphyte on Ascophyllum nodosum L. or on Fucus vesiculosus L.
Polysiphonia nigra (Huds.) Batters: (Fr 88, WI 113 as
Polysiphonia atrorubescens (?), Si 124).
Polysiphonia orthocarpa Rosenv. (WI 180). The presence of this little known boreal taxon (South and
Tittley 1986) in the Mediterranean Sea needs confirmation.
447
Ptilota gunneri P. C. Silva et al.: (Fr 147 and Tu 17 as
Ptilota plumosa auctorum). Since neither descriptions nor illustrations were given, the occurrence
of this Boreo-Atlantic species in the Mediterranean Sea should be confirmed.
Rhodomela confervoides (Huds.) P. C. Silva: (Fr 190).
Since neither descriptions nor illustrations were
given, the occurrence of this Boreo-Atlantic species in the Mediterranean Sea should be confirmed.
Rhodoptilum plumosum (Harv. et Bailey) Kylin: (Si 128
and Gr 120 and Tu 17 as Dasyopsis plumosa (Harv.
et Bailey) F. Schmitz). According to Athanasiadis (1987: 87), the records of this Pacific taxon from the Mediteranean Sea are doubtful.

illegitimate because it is a later homonym of both
P. parvula (C. Agardh) Mont., a taxon of unknown application, and P. parvula Zanardini,
which A. De Toni (1907) referred to Lophosiphonia subadunca (5 L. obscura).
