Fellhaneropsis vezdae (Coppins & P. James) Sérus. & Coppins

Lichenologist, 28: 208, 1996. Basionym: Bacidia vezdae Coppins & P. James - Lichenologist, 10: 190, 1978.

Synonyms: Fellhanera vezdae (Coppins & P. James) V. Wirth

Distribution: S - Cal (Puntillo & Vězda 1994, Puntillo 1995, 1996, 2000).

Description: Thallus crustose, ecorticate, thinly episubstratic, pale greenish grey. Apothecia biatorine, constricted at base, 0.2-0.4 mm across, pinkish brown to grey-brown, at first with a flat disc and an evident proper margin, soon becoming convex and immarginate, sometimes tuberculate. Proper exciple of vertically arranged hyphae with elliptical to polyhedral cells, to 15 µm wide laterally, colourless throughout or very pale brown in innermost part; epithecium reddish brown; hymenium colourless or pale brown, 40-45 µm high, I+ blue; paraphyses branched and anastomosing, 0.5-1 µm thick, forming a densely interwoven network around the ascus tips; hypothecium thin, dark brown. Asci 8-spored, clavate, with a K/I+ blue apical dome containing a darker blue, tubular ring-structure, and an amyloid coat, Byssoloma-type. Ascospores 3-7-septate, hyaline, acicular-fusiform, slightly curved, 30-42 x 3-4.5 µm. Pycnidia frequent, sessile, globose to flask-shaped, pink-brown to finally brown-black, up to 0.2 mm across, with a relatively wide ostiole. Conidia thread-like, colourless, simple or indistinctly septate, curved, (20-)30-43 x 0.5-1 µm. Photobiont chlorococcoid, the cells 4-7 µm wide. Spot tests: thallus K-, C-, KC-, P-. Chemistry: without lichen substances.

Note: a mild-temperate lichen found on bark of broad-leaved (especially Quercus) and coniferous (e.g. Abies) trees in very humid, open forests, especially on basal parts of trunks, sometimes foliicolous (e.g. in Calabria). It is included in the Italian red list of epiphytic lichens as “Critically Endangered” (Nascimbene & al. 2013c).

Growth form: Crustose

Substrata: bark and leaves
