Description: Thallus crustose, episubstratic, rather thick, warted-areolate, pale greenish yellow to yellowish brown, usually turning brown in the herbarium, forming up to 8(-10) cm wide patches, rarely delimited by a black prothallus. Areoles mostly contiguous, up to 2 mm wide, flat to convex. Cortex up to 60 µm thick, of thick-walled hyphae with cylindrical lumina, containing crystals dissolving in K; medulla white, of loosely interwoven, thin-walled hyphae, I-. Apothecia biatorine, black to brown-black, somehow shiny, 0.5-2(-3) mm across, with a flat to finally irregularly convex, epruinose disc, and a thin, poorly evident, soon excluded proper margin. Proper exciple poorly developed, with a dark brown to dark green-brown rim, paler brown within; epithecium bluish green-black, sometimes in part brown; hymenium colourless, 60-80 µm high, I+ blue; paraphyses coherent, sparingly branched and anastomosing, 3-4 µm thick in lower part, the apical cells to 8 µm wide, with a sharply delimited pigmented zone in the wall, covered by a green gel; hypothecium colourless in upper part, pale yellow-brown in lower part, I-. Asci 8-spored, clavate, the K/I+ blue tholus penetrated by a faintly amyloid apical cushion with parallel or diverging flanks, the wall K/I-, surrounded by a K/I+ blue outer layer, Lecanora-type. Ascospores 1-celled, hyaline, ellipsoid, (7.5-)9-13.5(-16) x (4.5-)5-7.5(-8.5) µm. Pycnidia dark, immersed, the wall greenish around the ostiole. Conidia hyaline, short-bacilliform, straight, 6-9 x 1-2 µm. Photobiont chlorococcoid. Spot tests: cortex K+ yellow, C-, KC+ yellow, P-; medulla K+ yellow-orange, C+ yellow, KC-, P+ orange or rarely P-. Chemistry: Chemotype I: atranorin, usnic and bourgeanic acids (the most common in the Alps). Chemotype II: atranorin, usnic, bourgeanic, and stictic acids, Chemotype III: atranorin and bourgeanic acid, chemotype IV: atranorin only.Note: an arctic-alpine, circumpolar species found on inclined faces of hard siliceous rocks in upland areas.
