Distribution: N - Ven (Jatta 1909-1911), Lig (S-F255427). S - Camp (Puntillo & al. 2000, Nimis & Tretiach 2004, Etayo & Puntillo 2011), Cal (Nimis & Puntillo 2003, Puntillo 2011, Puntillo & Puntillo 2012).
Description: Thallus crustose, rather thick, smooth and shiny, pale pink-brown, pale brown or cream-coloured, often delimited from conspecific thalli by a dark prothallus, forming extended mosaics. Apothecia brown-red to brown-black, lirelliform, totally immersed in the thallus, long and sinuous, rarely branched or stellate, 0.5-3(-5) x 0.1-0.2 mm. Proper exciple very thin, brownish, not extending below the hymenium, C+ fleeting red; epithecium brown; hymenium colourless I+ wine-red; paraphyses 0.8-1 μm thick, branched in upper part and anastomosing, conglutinated, not swollen at tips; hypothecium colourless. Asci 8-spored, cylindrical to cylindrical-clavate, fissitunicate, with a short ocular chamber surrounded by a thin, K/I+ dark blue ring. Ascospores (5-)9-17-septate, hyaline, fusiform to almost acicular, straight or slightly curved, 30-65 x 3-4 µm. Pycnidia rare, immersed, dark brown. Conidia 1-celled, hyaline, thread-like, 12-17 μm long. Photobiont trentepohlioid. Spot tests: thallus K- or K+ pale yellow, C-, KC-, P+ yellow-orange. Chemistry: thallus with psoromic and 2’-0-demethylpsoromic acid; exciple with gyrophoric acid.
Note: a mild-temperate to humid subtropical, mainly western species in Europe (but ranging from Macaronesia eastwards to the Black Sea area), known from a few stations only in Italy, on smooth bark in humid-warm woodlands. It is included in the Italian red list of epiphytic lichens as “Endangered” (Nascimbene & al. 2013c).
