Description: Thallus crustose, pale grey to dark grey-brown, rimose to verruciform or sometimes granular, without a distinct hypothallus, but often delimited by a brownish prothallus. Cortex of hyaline hyphae with globose lumina; medulla white, I-. Apothecia lecanorine, sessile, often contiguous and angular by mutual compression, (0.5-)0.7-1(-1.3) mm across, with a dark brown, flat to rarely slightly convex disc, a proper margin visible as a parathecial ring, and a thick, entire, usually persistent thalline margin. Thalline exciple corticate, the cortex up to 60 µm wide, of round, large, thin-walled more or less isodiametrical cells with 5-8(-10) µm wide, globose lumina, expanded below in a prosoplectenchymatous tissue, I-; proper exciple 15-20 µm wide laterally, expanding to 40 µm in upper part; epithecium brown, K-; hymenium colourless, 75-110(-130) µm high, I+ blue; paraphyses 1.7-2.3 µm thick at mid-level, the apical cells up to 4.5 µm wide; hypothecium colourless or yellowish, 50-95(-130) µm high, I+ blue. Asci 6(-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, not constricted at septum, brown, ellipsoid, (16-)18-23(-26) x (8.5-)10-12(-14) µm, often poorly developed, Physcia-type, without a torus and with well-developed lumina, the wall strongly warted already in young spores, with ontogeny of type A (apical wall thickening after septum formation). Pycnidia frequent, especially around the base of apothecia, black, immersed. Conidia bacilliform. Photobiont chlorococcoid. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
