Description: Thallus crustose, episubstratic, brown-green, green or olive-green, epruinose, forming irregular, sometimes confluent, up to 10 cm wide patches, the central part often warted-areolate, the marginal part often lobate, the lobes usually short and flat, sometimes not well developed. Apothecia cryptolecanorine, sessile, 0.3-0.5(-0.8) mm across, with a pale to dark brown, flat to finally convex disc and a thin, poorly visible and often finally excluded thalline margin. Epithecium colourless to pale brown; hymenium colourless, 35-40 μm high: paraphyses simple, coherent, clavate; hypothecium colourless, 50-90 μm high. Asci 8-spored, cylindrical-clavate, with a K/I+ blue outer coat and a K/I+ uniformly blue apical dome, approaching the Catillaria-type. Ascospores 1-septate, hyaline, narrowly ellipsoid with rounded ends, (10-)12.16 x 2.5-4 μm. Pycnidia immersed in the thallus. Conidia bacilliform, 3.5-4.5 x 0.5-0.9 μm. Photobiont chlorococcoid. Spot tests: cortex K-, C-, KC-, P-, UV-; medulla P+ orange-red. Chemistry: medulla with pannarin and zeorin (both major).
Note: a Mediterranean-Atlantic species found on large boulders of calcareous or basic siliceous rocks, usually on surfaces near the ground or on seepage tracks, especially in open woodlands of Tyrrhenian Italy.
