Gyalideopsis calabrica Puntillo & Vězda

Webbia, 46: 159, 1991.
Synonyms:
Distribution: S - Cal (Puntillo 1996).
Description: Thallus crustose, very thin and film-like, the hyphae often penetrating inside the cells of mosses, grey-green, sometimes poorly visible. Hyphophores hooked, 0.12-0.15 mm wide, shortly stalked, brown or brown-black, forming an apical flange with several short, lateral projections. Diahyphae filiform, multi-septate, not constricted at septa, 70-150 x c. 1.5 µm, straight or slightly curved. Apothecia unknown. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
Note: on epiphytic bryophytes and on bark of Fagus in old, undisturbed, very humid forests. This species might prove to be a synonym of G. muscicola P. James & Vezda: the species was established on account of its filiform versus presumably moniliform diahyphae in G. muscicola, but the latter species is characterised by filiform diahyphae as well (see Lücking & al. 2006). The species is included in the Italian red list of epiphytic lichens as “Critically Endangered” (Nascimbene & al. 2013c).
