Synonyms: Bacidia buxi Vězda & Vivant; Bacidia gorgonea Vězda & Poelt; Bacidia myriocarpa Erichsen; Fellhanera buxi (Vězda & Vivant) Vězda; Fellhanera myrtillicola (Erichsen) Hafellner
Description: Thallus crustose, thin and smooth to rarely granulose or slightly verrucose, greenish grey to bluish grey, somehow glossy, forming small, suborbicular patches which eventually merge to cover larger areas, usually delimited by a bluish prothallus. Apothecia biatorine, constricted at base, 0.1-0.2(-0.3) mm across, with a flat to convex, pale brown to bluish grey or bluish black disc and a thin, whitish, soon excluded proper margin. Proper exciple of vertically arranged hyphae with elliptical to polyhedral cells, up to 15 µm wide laterally, colourless throughout or very pale brown in innermost part; epithecium scarcely differentiated from the hymenium; hymenium colourless, I+ blue; paraphyses branched and anastomosing, 1-1.5 µm thick, forming a densely interwoven network around the ascus tips; hypothecium very thin, dark brown, K+ greenish brown to green in central parts. 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(-5)-septate, hyaline, oblong-fusiform, straight or slightly curved, 16-28(-34) x 3-4 µm. Pycnidia dark grey to blue-black, immersed in the apothecia or sessile on the thallus, with palisadic hyphae on rim of ostiole (enclosing the conidial mass at least when young), producing (12-)20-45 µm long, thread-like macroconidia, or 4-8 µm long, bacilliform microconidia, respectively. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
