Description: Thallus crustose, episubstratic, rimose-areolate to warted, up to 1.5-2.5 mm thick, olivaceous brown, grey-brown or dark brown, often forming up to 10 cm wide patches, rarely delimited by a thin, black prothallus. Areoles mostly contiguous, irregular in shape, 0.6-1.5(-3) mm across, usually convex, epruinose, more or less glossy. Cortex 20-30 µm thick, with a brown upper layer overlain by a thin epinecral layer; medulla white or pale yellowish, I-. Apothecia lecanorine, at first immersed to adnate, later sessile, round or weakly angular by mutual compression, (0.4-)1-1.5(-2.5) mm across, with a chestnut brown to brown-black, slightly concave to convex, glossy and epruinose disc, and a usually paler, thick, entire to crenulate, persistent thalline margin. Thalline exciple corticate, c. 45 µm wide, with fine granules soluble in K; proper exciple poorly delimited, brown in outer part, colourless within, forming a 40-100 µm thick cupular layer below the hypothecium; epithecium olive-brown to yellowish brown, without granules, 10-20 µm thick; hymenium colourless, 50-70(-80) µm high, I+ blue; paraphyses coherent, branched in upper part, rarely anastomosing, 3-4 µm thick at mid-level, the apical cells 4-6 µm wide, with pale brown walls and a dark brown cap; hypothecium colourless or pale yellow. Asci 8-spored, clavate, approaching the Lecanora-type, with or without an ocular chamber, but always with a distinct, non-amyloid apical cushion. Ascospores 1-celled, hyaline, fusiform with pointed apices, (8-)10-13(-16) x (3-)4-6(-7) µm, the wall to 0.3 µm thick. Pycnidia immersed, black around the ostiole. Conidia straight, acicular, 6-9(-11) µm long. Photobiont chlorococcoid. Spot tests (better visible on microscopic sections): medulla K- or K+ pale yellow, C-, KC- or rarely KC+ fleeting pink to red-violet, P-, usually UV+ white. Chemistry: lobaric acid (major), zeorin, and unknown substances (minor, traces or absent).
