Description: Thallus crustose, episubstratic, thin, continuous to areolate, the areoles (0.2-)0.5-1 mm wide, whitish grey to greenish grey, dull, without a distinct prothallus. Apothecia lecanorine, sessile, 0.3-0.8 mm across, with a black, flat to convex disc, and a thick, entire, usually persistent thalline margin. Thalline exciple 50-80 µm thick laterally, corticate, the cortex 25-35 µm thick laterally, expanding to 50(-80) µm in lower part, I+ pale blue; proper exciple colourless to lightly pigmented, 5-15 µm thick laterally; epithecium dark reddish brown, K-, N-, P- or P+ orange; hymenium colourless, 80-100(-120) µm high; paraphyses more or less coherent, 2-2.5 µm thick at mid-level, the apical cells up to 3.5(-4.5) 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, ellipsoid, (16-)19-23(-27) x (8.5-)10-11(-12.5) µm, Physcia-type, the wall minutely warted, the torus developed, with spore ontogeny of type A (apical wall thickening after septum formation). Pycnidia infrequent, immersed. Conidia bacilliform, 4-5 µm long. Photobiont chlorococcoid. Spot tests: cortex K+ pale yellow, C-, KC-, P- or P+ faintly yellow. Chemistry: atranorin in cortex, zeorin (traces) in the medulla, pannarin sometimes in the epithecium.
Note: a cool-temperate to boreal-montane pioneer species, mostly found on smooth bark, but also on lignum, with optimum in the subalpine and montane vegetation belts; the species is also known from the Canary Islands.
