Description: Thallus crustose, episubstratic to hemiendosubstratic, usually c. 1 mm thick, continuous, white, bluish white, or ochre-coloured, sometimes inapparent, often greenish or blue-green when wet, sometimes surrounded by a white prothallus. Medulla I-, filled with crystals of calcium oxalates and overlain by a distinct epinecral layer of dead, compacted cells. Apothecia lecideine to biatorine, round to irregular in outline, (0.3-)0.5-1.2(-1.5) mm across, slightly immersed in the thallus to subsessile, leaving distinct depressions when falling off, with a black (reddish-brown when moist), usually flat disc, and a very thin, soon excluded proper margin. Proper exciple dark red-brown in outer part, almost colourless within, of more or less radially arranged hyphae, 20-110 µm thick laterally, much thinner at base; epithecium ochraceous to reddish brown; hymenium colourless, 65-132 µm high, I+ reddish and partly pale blue; paraphyses sparingly branched and anastomosing, septate but not moniliform, 4-5.5 µm thick at mid-level, scarcely swollen at apex; hypothecium narrowly stem-like, deeply immersed, colourless to pale brown in upper part, at least partially I+ blue. Asci 8-spored, elongate-clavate, with a thin, outer amyloid layer and a thickened tholus penetrated by a pore, the sides of which stain K/I+ deep blue, Porpidia-type. Ascospores 1-celled, hyaline, ellipsoid, (8-)13-18(-22) x 5-7(-10) µm, with a > 1 µm thick, gelatinous perispore when young, the wall of old spores not warted. Pycnidia black, laminal, immersed. Conidia bacilliform, 4-6 x 1-2 µm, with apical and lateral conidiogenesis. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
