Description: Thallus minutely squamulose, episubstratic, growing in very fine cracks of calciferous rocks. Squamules adpressed, scattered, 1-5 mm wide, finally deeply lobed, c. 500 μm thick, smooth, epruinose, pale to medium brown, paler at the usually raised margins, the lower surface dirty white to pale brown, attached by bundles of rhizines. Cortex overlain by a epinecral layer; medulla white, I-. Apothecia almost always present, lecideine, reddish brown to almost black, often crowded, sessile, 0.5-1.5 mm across, at first with a flat disc and a prominent margin, finally convex and often immarginate, epruinose. Proper exciple and hypothecium thick, medium to dark brown, of conglutinated hyphae; epithecium brown; hymenium colourless, c. 60-80 μm high; paraphyses coherent, 2-2.5 μm thick, slightly swollen and brown at apex; hypothecium and lower part of hymenium with blue-black granules reacting K+ green. Asci 8-spored, clavate, with a I+ blue tholus and an internal, darker I+ tubular structure, the external gel I+ faintly blue, Porpidia-type. Ascospores 1-celled to sometimes finally 1-septate, hyaline, ellipsoid to narrowly ellipsoid, (9-)10-15.5(-18) x 4-5 μm. Photobiont chlorococcoid. Spot tests; cortex and medulla K-, C-, KC-, P-, UV-. Chemistry: thallus apparently without lichen substances.
