Umbilicaria nylanderiana (Zahlbr.) H. Magn.

Lich. Sel. Scand. Exs.: 252, 1937. Basionym: Gyrophora nylanderiana Zahlbr. - Cat. Lich. Univ, 4: 720, 1927.

Synonyms: Umbilicaria corrugata Nyl.

Distribution: N - TAA (Nascimbene 2008b, Nascimbene & al. 2022), Lomb (Gheza 2019b), Piem (Isocrono & al. 2004, Isocrono & Piervittori 2008), VA (Piervittori & Isocrono 1999, Piervittori & al. 2001, 2004). C - Tosc (Tretiach & al. 2008), Sar. S - Bas (Potenza & al. 2014), Cal (Puntillo 1996), Si (Ottonello & Isocrono 2004, Iacolino & Ottonello 2006).

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 lesseven, 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.
