Description: Thallus squamulose, forming small, up to 1.5 cm wide patches, dark brown to dark grey, rarely weakly white-pruinose, never white-maculate, the squamules scattered to partly imbricate, round to elongated, often crenulate, slightly convex, up to 2 mm wide. Upper cortex 50-120 μm thick, with an up to 70 μm thick epinecral layer; algal layer continuous; medulla white, lacking crystals. Apothecia frequent, lecideine, sessile, up to 1 mm across, black, epruinose or faintly pruinose, usually persistently flat and marginate. Proper exciple dark reddish brown, K-, N-; epithecium dark brown, sometimes with a faint green tinge, K-, N- or (green pigment) N+ faintly violet, lacking crystals; hymenium colourless, 60-80 μm high; paraphyses not conglutinated, simple or sparingly branched and anastomosing in upper part, thin-walled, the apical cell distinctly swollen and covered by a gelatinous pigment cap; hypothecium dark reddish brown. Asci 8-spored, clavate, surrounded by a gelatinous I+ blue coat, with a well-developed I+ blue tholus, a I+ darker blue tube and a well-developed ocular chamber, Bacidia-type. Ascospores (1-)3-septate, hyaline, ellipsoid to bacilliform, 10-19 x 3.5-5 μm. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: thallus without lichen substances.
Note: an arctic-alpine to cool-temperate lichen found in fissures and fine crevices of calcareous rocks in upland areas, often growing on species of Placynthium when young.
