Description: Thallus foliose-umbilicate, heteromerous, dorsiventral, 2-8(-10) cm wide, monophyllous, rarely polyphyllous, of variable thickness, attached by a central holdfast, the margins often down-turned, rounded or lacerate. Upper surface pale brown to brownish grey with reddish spots, dull, rimose, scabrous, over the umbilicus covered with whitish areoles which become more and more distinctly powdery-sorediate toward margins. Lower surface medium brown to buff, slightly areolate, often darker around the umbilicus in old specimens, sometimes black, with darker trabeculae radiating from the umbilicus and sometimes reaching the margins; rhizinomorphs simple or moderately to densely branched, cylindrical, strap-like, absent around the umbilicus, concolorous or slightly darker; thalloconidia absent. Upper cortex paraplectenchymatous, 20-30 µm thick; medulla white, loose; lower cortex brown, scleroplectenchymatous, 20-60 µm thick. Apothecia rare, black, weakly gyrodisc, 0.5-2 mm across. Epithecium brown; hymenium colourless to brownish, often divided into compartments by columns of sterile tissue; paraphyses simple or sparingly branched, the apical cells more or less swollen; hypothecium thick, dark. Asci 8-spored, clavate, thick-walled, with an amyloid apical dome, Umbilicaria-type. Ascospores 1-celled hyaline, ellipsoid, 10-14 x 3-8 µm. Photobiont chlorococcoid. Spot tests: medulla K-, C+ red, KC+ red, P-. Chemistry: medulla with gyrophoric acid and small amounts of lecanoric acid.

Note: a widespread, arctic-alpine to boreal-montane, circumpolar lichen found on steeply inclined to slightly rain-sheltered surfaces of siliceous rocks, often in somehow dusty situations; common in the Alps, rarer in the Apennines and in the mountains of Sicily, also for the scarcity of suitable substrata.
