Description: Thallus crustose, thick, areolate, pale to dark grey or rarely grey-brown, the areoles flat to subconvex, smooth, often with brown margins, without a distinct prothallus. Apothecia cryptolecanorine to rarely lecanorine, up to 1 mm across, immersed to subsessile, usually more than one per areole, with a dark brown to black, flat to weakly convex disc and a persistent thalline margin level with thallus. Epithecium reddish brown, 15-30 µm thick; hymenium colourless, up to 90 µm high, not inspersed with oil droplets; paraphyses c. 1.5 µm thick at mid-level, the apical cells up to 6 µm wide; 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, brown, 13-20 x 7.5-12 µm, Bicincta-type, with a heavily pigmented band around each lumen, without a torus, the ontogeny of type A (apical wall thickening after septum formation). Pycnidia black, immersed. conidia bacilliform, 4-6 x c. 1 µm. Photobiont chlorococcoid. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: zeorin.
Note: on the top of isolated boulders of limestone and dolomitic rocks, usually on nutrient-enriched surfaces such as in birds’ perching sites, often starting the life-cycle on Rinodinella controversa, with a wide altitudinal range but usually absent above treeline.
