Description: Thallus crustose, episubstratic, rimose-areolate, often delimited by a black prothallus, the areoles up to 0.5-1 mm wide, smooth to rugose, grey-brown, reddish brown or dark brown, dull. 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, persistent thalline margin. Thalline exciple 60-100 µm wide laterally, corticate; proper exciple colourless, 5-20 µm wide laterally, expanding to 10-40 µm in upper part; epithecium reddish brown; hymenium colourless, (65-)100-120 µm high; paraphyses 1.5-2.5 µm thick at mid-level, not conglutinate, 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 and ornamented walls, the ontogeny of type A (apical wall thickening after septum formation). Pycnidia immersed. Conidia bacilliform, 4-5 µm long. Photobiont chlorococcoid. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances. Note: a cool-temperate to arctic-alpine, circumpolar lichen found on boulders of siliceous rocks, usually on steeply inclined surfaces, often (but not always) parasitic on other crustose lichens; the Italian distribution ranges from the Alps to the high Mediterranean mountains, with optimum near or above treeline.
