Description: Thallus crustose, episubstratic, areolate, white, at first forming scattered, small, orbicular patches (1-2 mm diam.) on the thalli of other lichens, then the patches becoming confluent. Upper cortex obscurely pseudoparenchymatous, with minute calcium oxalate crystals that are insoluble in K; medulla white, I-. Apothecia lecideine, 0.3-0.7(-1.5) mm across, at first immersed, then emergent, black but whitish-pruinose at least when young, with a flat to convex disc and a very thin, soon excluded proper margin, without a pseudothalline margin. Epithecium brown; hymenium colourless, I+ blue; paraphyses simple with enlarged, pigmented apical cells; hypothecium dark brown. Asci 8-spored, clavate to cylindrical-clavate, the apical dome K/I+ dark blue with a pale, conical-pointed apical cushion (axial mass), the wall I-, but the thin outer gel I+ blue, approaching the Bacidia-type. Ascospores submuriform, brown, very thick-walled, not ornamented, straight or slightly curved, (13-)16-20(-25) x (6-)8-9(-11) µm. Photobiont chlorococcoid. Spot tests: K-, C.-, KC-, P-, UV-.
