Description: Thallus foliose-umbilicate, heteromerous, dorsiventral, monophyllous, rigid, 2-4(-5) cm wide, 0.3-0.5 mm thick at the level of the ridges, thinner elsewhere, attached by a very thick, short and compact central holdfast. Upper surface ash-grey, scabrous, with a white, reticulately ridged pattern, the central part raised, the marginal parts adpressed or undulating, strongly wavy, often down-turned. Lower surface black or dark brown in places, paler at margins, even or shallowly pitted, sometimes radiately folded around umbilicus, erhizinate. Thalloconidia covering the whole lower surface, 1-celled, spherical to oval, dark brown to black, 7.3-8.5 µm in diam. Upper cortex dark brown, palisade-plectenchymatous, 25-30 µm thick; medulla white, very loose under the ridges; lower cortex scleroplectenchymatous, x 20-35 µm thick. Apothecia very rare, black, stipitate, omphalodisc. Asci 8-spored, clavate, thick-walled, with an amyloid apical dome, Umbilicaria-type. Ascospores 1-celled hyaline, ellipsoid, 6-14 x 4-8 µm. Photobiont chlorococcoid. Spot tests: K-, C+ red or rarely C-, KC+ red or rarely KC-, Note: an arctic-alpine to boreal-montane, circumpolar lichen found on steeply inclined to slightly rain-sheltered surfaces of wind-exposed siliceous rocks, reaching the nival belt in the Alps, and also reported from the mountains of Calabria.
Growth form: Foliose, umbilicate
Substrata: rocks
