Description: Thallus crustose, episubstratic, rimose- to verrucose-areolate, grey or greenish to brownish grey, scabrid, dull, epruinose, sometimes with a white prothallus, consisting of irregularly angular, 0.4-1.5 mm wide and up to 3.5 mm thick, contiguous, flat to convex areoles. Apothecia urceolate, semi-immersed to sessile, up to 3.5 mm across, with a black, usually slightly white-pruinose, concave disc, and a thick, raised proper margin. Proper exciple blackish, up to 75 µm thick laterally, pseudoparenchymatous; epithecium poorly differentiated, colourless to brownish; hymenium colourless, (90-)100-125(-140) µm high, non-amyloid; paraphyses simple, 1-2 µm thick, the apical cells not swollen; hypothecium colourless, 10-15 µm high. Asci (4-)8-spored, narrowly clavate to subcylindrical, the wall evenly thickened when mature, the somewhat abrupt apical thickening with a thin, internal apical beak, lacking any apical apparatus, the contents I+ orange-red, the walls I-, not fissitunicate. Ascospores muriform, with 4-7 transverse and 1-3 longitudinal septa, at first hyaline then turning brown, broadly ellipsoid, (20-)25-40 x 10-20 µm. Pycnidia immersed, crateriform. Conidia bacilliform, 4-6 x 1 µm. Photobiont chlorococcoid. Spot tests: thallus K-, K+ yellow, or K+ yellow turning violet red-brown, C+ red, KC-, P-, UV-. Chemistry: lecanoric acid (major), diploschistesic acid (major or absent).Note: a widespread holarctic lichen found on siliceous rocks, more rarely on soil, with a wide altitudinal range. Formerly frequently confused with similar species. The species, in its present circumscription, seems to be heterogeneous (see Fernández-Brime & al. 2013).
