Description: Thallus crustose, usually endolithic and not apparent, sometimes visible as a thin, pale grey to olive-brown film around the apothecia. Apothecia lecideine, more or less immersed to sessile, often deformed by mutual compression, 0.3-0.8(-1) mm across, scattered or clustered, but most often arranged in lines along rock crevices, with a black to brown-black, round, flat to slightly concave, non-gyrose disc, and a concolorous, crenulate margin extending to disc and sometimes giving it an umbonate appearance. Proper exciple carbonized in outer part, yellowish to colourless within, 35-55 µm wide laterally; epithecium blackened, with reddish areas; hymenium colourless, (60-)90-130(-180) μm high, often divided by sterile columns of conglutinated hyphae, usually I+ blue eventually turning red; paraphyses coherent, richly branched, 1-1.5(-2) µm thick at base, hardly expanded at apex; hypothecium colourless. Asci >200-spored, clavate to subcylindrical, strongly thickened at apex, the apical dome K/I-, the outer coat K/I+ blue. Ascospores 1-celled, hyaline, narrowly ellipsoid to almost bacilliform, 3-5(-6) x 1-1.5 μm. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.Note: a holarctic early coloniser of small cracks of siliceous, sometimes base-rich or slightly calciferous rocks.
