Synonyms:
Description: Thallus crustose, episubstratic, black-brown, olive or dark grey-green, thin to thick, continuous or weakly rimose, subgelatinous and more or less transparent in marginal parts when wet. Uppermost parts of thallus yellowish to brown, paraplectenchymatous; medulla poorly developed, sometimes with a an orange-brown basal layer. Perithecia black, 0.2-0.3 mm across, basally immersed in the rock, otherwise immersed in projecting thalline warts, exposing only the naked ostiolum. Involucrellum apical to reaching the thallus base and laterally extended in the thallus; exciple colourless to very pale brown; hamathecium of up to 21 μm long periphyses and periphysoids, interascal filaments absent; hymenial gel I+ red (I+ blue at very low concentrations of I), K/I+ blue. Asci 8-spored, ellipsoid to clavate, 73-93 x 22-36 μm, I-, fissitunicate, the wall thickened above, with an ocular chamber, dehiscent by extrusion of a delicate rostrum. Ascospores (1-)2(-3)-septate, hyaline ellipsoid. (25-)30-40 x 10-15 μm. Photobiont chlorococcoid. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
