Description: Thallus crustose, episubstratic, to 0.5 mm thick, areolate, without a distinct prothallus. Areoles up to 1.3-1.4 mm wide, contiguous, flat, whitish to grey, rarely grey-brown, dull. Apothecia pseudolecanorine to lecideine, innate to adnate, 0.3-1 mm across, with a black, flat to slightly convex disc and a black, often sinuous proper margin. Proper exciple colourless, 10-15 µm laterally, to 15-20 µm in upper part; epithecium reddish brown; hymenium colourless, 80-110 µm high; paraphyses 1.5-2 µm thick in lower part, conglutinate, the apical cells to 3-3.5 µm wide, immersed in a dispersed pigment; hypothecium colourless to pale brown, 70-180 µm high. 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, ellipsoid, 13-18 x 7-11 µm, with rugulate-ornamented walls, Milvina-type, with ontogeny of type A (apical wall thickening after septum formation). Pycnidia immersed in thallus. Conidia bacilliform, 5-6 µm long. Photobiont chlorococcoid. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: zeorin.

Note: an arctic-alpine species described from the Italian Alps and also known from the Karakorum Mountains, found on usually south-exposed surfaces of very hard, base-rich siliceous rocks and serpentine near and above treeline.
