Description: Thallus crustose, episubstratic, well-delimited and forming large patches, rimose-areolate, consisting of 0.5-1.5 mm wide and 0.2-1(-1.5) mm thick, irregularly angular, flat to slightly convex, whitish grey to grey, smooth, epruinose areoles developing on a black hypothallus. Medulla white, I+ blue. Apothecia common, perithecioid, immersed in the thallus, usually 1 per areole, up to 1 mm across (in section), with a blackish, urceolate to finally flat disc not visible from above, being concealed by a thick, radially sulcate proper margin. Proper exciple up to 70 µm thick, carbonized, pseudoparenchymatous; epithecium poorly differentiated, colourless to brownish; hymenium colourless, 120-160 µm high, non-amyloid; paraphyses flexuose, 1-1.5 µm thick, not swollen at apex; hypothecium colourless, 10-15 µm high. Asci 4-6(-8)-spored, cylindrical to subclavate, the wall evenly thickened, with an abrupt apical thickening and a thin internal apical beak, lacking an apical apparatus, the contents I+ orange-red, the walls I-, not fissitunicate. Ascospores muriform, with 4-6 transverse and 1-3 longitudinal septa, at first hyaline but soon turning brown, ellipsoid, (16-)20-32(-40) x (10-)12-15(-20) µm. Pycnidia black, immersed. Conidia bacilliform, 4-7 x c. 1 µm. Photobiont chlorococcoid. Spot tests: thallus K-, C+ red, P-, UV-. Chemistry: lecanoric acid (major), diploschistesic and orsellinic acids (minor).
