Description: Thallus crustose, episubstratic, areolate, up to 0.35 mm thick, grey to grey-brown or almost black in exposed situations, often delimited by a black prothallus, forming up to 4 cm wide patches. Areoles angular, flat to bullate, 0.2-0.8 mm wide, usually esorediate, rarely with blackish soralia. Cortex green-grey to brown-green, 10-20 µm thick; medulla white, I-. Apothecia black, at first immersed, then sessile, 0.3-1(-2) mm across, with a flat to finally convex, epruinose disc, and a distinct and persistent, rarely finally excluded margin. Proper exciple 35-70 µm wide, with a 10-25 µm thick, greenish grey to greenish black cortex, pale to dark brown within, consisting of 3.5-4.5 µm thick hyphae; epithecium green, sometimes with pale blue to violet granules, rarely totally violet, N+ purple; hymenium colourless, 60-90(-120) µm high, I+ blue; paraphyses (in K) easily made free, branched in upper part, not anastomosing, 1.5-2 µm thick at mid-level, the apical cells only slightly swollen, 2.5-3 µm wide; hypothecium colourless in upper part, brown in lower part. Asci 8-spored, cylindrical to cylindrical-clavate, thin-walled, with a single wall layer, not thickened apically, only the outermost gelatinous layer K/I+ faintly blue, discharge by splitting of the apex, Schaereria-type. Ascospores 1-celled, ellipsoid to broadly obpyriform, (9-)11-14(-18) x (4-)5-7(-9) µm, rather thick-walled. Pycnidia dark, immersed. Conidia cylindrical, 4-7 x 0.9-1 µm. Photobiont chlorococcoid. Spot tests: medulla and exciple K-, C+ pink, KC+ pink, P-. Chemistry: gyrophoric acid (major) and lecanoric acid (minor).

Note: an arctic-alpine to boreal-montane, circumpolar species found on hard siliceous rocks in exposed situations, with optimum above treeline, reaching the nival belt in the Alps; common only in the Alps, much rarer in the Apennines.
