Bibl. Univ. de Genève, 36: 153, 1841.
Synonyms: Gyrophora stipitata (Nyl.) Branth; Gyrophora virginis (Schaer.) Frey; Umbilicaria rugifera Nyl.; Umbilicaria stipitata Nyl.
Distribution: N - TAA, Lomb (Rivellini 1994), Piem (Isocrono & Falletti 1999, Isocrono & al. 2003, Isocrono & Piervittori 2008), VA (Piervittori & Isocrono 1999).
Description: Thallus foliose-umbilicate, heteromerous, dorsiventral, monophyllous, rigid, more or less circular in outline, 1.5-4(-20) cm wide, attached by a more or less central holdfast. Upper surface ivory to light grey or brownish grey, dull, with sharp radiating ridges and coarsely pruinose near the umbilicus. Lower surface white to pink, smooth to minutely roughened, usually brown-black around the umbilicus, with dense, long, slender, white, branched rhizinomorphs; thalloconidia absent. Apothecia common, black, weakly omphalodisc, sometimes with several circular elevations, sessile to substipitate, up to 3 mm across. Epithecium black-brown; hymenium colourless; paraphyses mostly simple, with enlarged apical cells; hypothecium brown. Asci 8-spored, clavate, thick-walled, with an amyloid apical dome, Umbilicaria-type. Ascospores 1-celled, hyaline, ellipsoid, 10-15 x 5-8 µm. Photobiont chlorococcoid. Spot tests: medulla K- or K+ red, C+ red, KC+ red, P- or P+ orange. Chemistry: medulla with gyrophoric acid and variable amounts of stictic acid. Note: an arctic-alpine, probably circumpolar lichen found on wind-exposed siliceous cliffs, often in small niches and under overhangs, strictly limited to the nival belt in the Alps.
