Umbilicaria subglabra (Nyl.) Harm.
Lich. France, 4: 707, 1910. Basionym: Gyrophora subglabra Nyl. - Lich. Envir. Paris: 135, 1896.
Synonyms: Agyrophora subglabra (Nyl.) M. Choisy; Umbilicaria subglabra var. schmidtii Frey?
Distribution: N - Frl (Codogno 1995), TAA, Lomb (CLU 688), Piem (Isocrono & al. 2006), VA (HAL-782).
Description: Thallus foliose-umbilicate, dorsiventral, monophyllous, more or less circular in outline, rigid, often with ragged margins, 1-3(-6) cm in diam. Upper surface pale to dark grey, dull, smooth to minutely roughened, with a white necral layer centrally, and a few short folds or ridges or numerous fine striae radiating from the umbo. Lower surface smooth, dull, grey or patchily sooty black where covered with the simple, dark brown thalloconidia. Apothecia rare, black, leiodisc. Asci 8-spored, elongate-clavate, thick-walled, with an amyloid apical dome, Umbilicaria-type. Ascospores 1-celled, hyaline, narrowly ellipsoid, 10-20 x 3-7 µm. Photobiont chlorococcoid. Spot tests: K-, C+ red, KC+ red, P-. Chemistry: medulla with gyrophoric acid.Note: on steeply inclined to horizontal, exposed surfaces of siliceous rocks, often at the top of large boulders; certainly widespread throughout the Alps.
