Description: Thallus foliose-umbilicate, dorsiventral, monophyllous but often deeply dissected and appearing polyphyllous, 2-3(-5) cm diam., attached by a thick, black central holdfast, with often lacerate and perforate, ascending and undulating margins. Upper surface dark brown, sometimes with a thin white necrotic layer over the umbilicus, rugose with vermiform ridges, towards the margins more or lesseven, smooth when young, later rugose, especially in the center. Lower surface sooty black, sometimes slightly paler at margins, smooth, even or dimpled, erhizinate. Thalloconidia simple, rarely 1-septate, spherical, dark brown covering the whole lower surface except sometimes the marginal zone. Upper cortex dark brown; medulla white; lower cortex 10-20 µm thick. Apothecia very rare, black, gyrodisc Pycnidia mainly marginal on upper surface, immersed, globose, with a dark brown ostiole. Conidia bacilliform. Photobiont chlorococcoid. Spot tests: K-, C+ red, KC+ red, P-. Chemistry: gyrophoric, lecanoric and umbilicaric acids.Note: an arctic-alpine, probably circumpolar lichen found on the top of isolated siliceous boulders, most frequent in the Alps above treeline, but reaching south to the mountains of Calabria.
