Description: Thallus crustose to subsquamulose, heteromerous, forming an up to 2 cm wide crust-like cover on a thin, blue-black hypothallus. Squamules to 1.5(-2) mm wide, remaining discrete at the margin of the crust, often imbricate in central parts, grey-brown to dark brown or almost black, indented. Upper cortex paraplectenchymatous with irregularly thickened cell walls, 15-20 µm thick; medulla white, loose, gradually merging into rhizohyphae; lower cortex absent. Apothecia common, to 1 mm across, with a brown to blackish, flat to convex disc and an often only partially developed, finally excluded thalline margin. Exciple variously developed, up to 60 µm thick, subparaplectenchymatous; epithecium brown-black; hymenium colourless, 100-120 µm high, hemiamyloid, I+ blue-green turning red-brown; paraphyses simple, the apical cells clavate; hypothecium colourless. Asci 8-spored, clavate to subcylindrical, with a thin, sheet-like, densely and persistently amyloid layer capping the endoascus and an amyloid exoascus, but no other densely amyloid internal structures. Ascospores 1-celled, hyaline, narrowly ellipsoid, 13-18 x 5-6 µm, without a perispore, often guttulate. Pycnidia very rare, immersed. Conidia bacilliform. Photobiont cyanobacterial (Nostoc, the cells in clusters). Spot tests: cortex and medulla K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
