Description: Thallus crustose, thick, rimose-areolate to areolate, smooth to granulose-verrucose, pale to dark grey or brownish. Apothecia lecanorine, immersed to adnate, up to 1 mm across, with a dark brown to black, flat to convex disc and an entire, persistent thalline margin; proper margin often visible as a ring within the thalline margin. Epithecium 10-20 µm thick, reddish brown; hymenium colourless, up to 120 µm tall, K/I+ blue; paraphyses c. 1.5 µm thick, the apical cells 3-5 µm wide, with a brown cap; hypothecium colourless. Asci 8-spored, narrowly clavate to 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, brown, ellipsoid, Mischoblastia-type with tendency towards the Pachysporaria-type when mature, 18-28(-32) x 10-15(-19) µm, swelling around the septum with K, torus absent. Photobiont chlorococcoid. Spot tests: thallus and medulla K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.

Note: a widespread species growing on base-rich siliceous rocks, mostly on more or less calciferous sandstone), especially in nutrient-enriched situations such as on walls, tiles, brick or gravestones, mostly below the montane belt, also found in large conurbations.
