Description: Thallus crustose, episubstratic, rimose-areolate, brownish-grey, ash-grey or dark grey-brown, forming irregular, up to 10 cm wide patches often delimited by a dark prothallus, the areoles angular, 0.2-0.5 mm wide, flat to usually convex, contiguous or dispersed over a black hypothallus, most often esorediate, but sometimes with brown (cream-coloured when eroded), orbicular, to 3 mm wide soralia, the soredia 60-80 μm wide. Medulla white, I-. Apothecia lecideine, brown-black to black, constricted at base, 0.4-0.8(-1.5) mm across, with a flat to convex, sometimes faintly grey-pruinose disc and a glossy, persistent, mostly raised and flexuous proper margin. Proper exciple 60-100(-160) μm wide laterally, dark brown-black in outer part, progressively paler inward, the pigmented parts K+ intensifying brown, the peripheral hyphae with more or less as long as wide lumina, those of the mnedullary part narrow, evenly thickened, with at least some lumina which are >3 times as long as wide; epithecium dark olive-brown; hymenium colourless, 55-80(-100) μm high, I+ blue; paraphyses lax, mostly simple, 1.5(-2) μm thick at mid-level, the apical cells 3-6 μm wide; hypothecium brownish, 100-180 μm high, inspersed with oil droplets. Asci 8-spored, clavate, the tholus with an inner amyloid zone, an outer amyloid zone and a less amyloid zone inbetween, surrounded by a slightly amyloid gelatinous matrix. Ascospores 6-7(-9)-septate, hyaline, acicular-clavate, attenuated at one end, (17-)25-40(-48) x 4-7 μm. Pycnidia immersed to sessile, dark brown-black, usually in clusters. Conidia bacilliform 3.5-6 x c. 1 μm. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: two or more unidentified substances; atranorin and parietin also reported from North American specimens.
