Description: Thallus foliose-umbilicate, heteromerous, dorsiventral, monophyllous, 3-5(-7) cm wide, 02-0.4 mm thick, the lobe margins with conspicuous but rather sparse, flat, branched, up to 2 mm long black cilia. Upper surface pale to dark grey, sometimes tinged brown, dull, slightly wrinkled or almost even, sometimes with a few folds and ridges around the umbilicus, giving way to a reticulate pattern. Lower surface grey-white, tan or pink, sometimes pink-brown towards the umbilicus and grey-pruinose in the marginal zone, even, smooth, the area around the umbilicus naked, the rest with numerous thin, long, cylindrical, pale, simple rhizinomorphs; thalloconidia absent. Upper cortex 10-20 µm thick; medulla white, 3-layered, the upper and lower layers loose, with an arachnoid plectenchyma, the layer inbetween with a compact plectenchyma; lower cortex 10-20 µm thick, scleroplectenchymatous. Apothecia numerous, black, gyrodisc, markedly stipitate, to 2-5 mm across, convex with few deep gyri. Epithecium dark brown, up to 20 µm high; hymenium colourless, c. 70 µm high; paraphyses usually simple, up to 2.5 µm thick, the apical cells hardly swollen; hypothecium dark. Asci 8-spored, clavate, thick-walled, with an amyloid apical dome, Umbilicaria-type. Ascospores 1-celled, hyaline, ellipsoid, 7-15 x 3-9 µm. Pycnidia numerous, immersed, bottle-shaped, with a brown wall, and a dark brown ostiole. Conidia c. 3-4 x 0.8 µm. Photobiont chlorococcoid. Spot tests: medulla K- or K+ yellow turning red, C-, KC- or KC+ faintly red, P- or P+ orange. Chemistry: medulla with variable amounts of norstictic acid and sometimes with very low amounts of gyrophoric and lecanoric acids.
Note: an ecologically wide-ranging, cool-temperate to arctic-alpine, circumpolar lichen found on wind-exposed boulders with a short snow-covering period, often on or near the top, with optimum above treeline, reaching the nival belt in the Alps; common only in the Alps, becoming much rarer southwards, also for the scarcity of suitable substrata, up to the mountains of Calabria.
