Description: Thallus crustose, episubstratic, rimose-areolate, often delimited by a black prothallus, the areoles up to 0.5-1 mm wide, smooth to rugose, dark grey, reddish brown or dark brown, dull. Medulla white, I-. Apothecia lecanorine, adnate to subsessile, contiguous, sometimes angular by mutual compression, 0.3-1(-1.5) mm across, with a dark brown to black, concave to flat, rarely slightly convex disc and a thick, smooth to crenulate, persistent thalline margin. Thalline exciple 60-100 µm wide laterally, corticate, without crystals; proper exciple colourless, 5-20 µm wide laterally, expanding to 10-40 µm in upper part; epithecium reddish brown, K-; hymenium colourless, (65-)100-120 µm high; paraphyses not strongly coherent, 1.5-2.5 µm thick at mid-level, the apical cells 3.5-5.5 µm wide, immersed in dispersed pigment; hypothecium colourless. Asci 8-spored, clavate, the K/I+ blue tholus penetrated by a faintly amyloid apical cushion with parallel or diverging flanks, the wall K/I-, surrounded by a K/I+ blue outer layer, Lecanora-type. Ascospores 1-septate, often constricted at septum, brown, broadly ellipsoid, (13-)16-19(-23) x (7-)9-11(-13) µm, Milvina-type, often grading into Pachysporaria-type at maturity, with a well-developed torus, the walls finely warted, the ontogeny of type A (apical wall thickening after septum formation). Pycnidia dark, immersed. Conidia bacilliform, 4-5 x 1-1.5 µm. Photobiont chlorococcoid. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
