Description: Thallus microfruticose-filamentous, brown-black to black, dark-green to brown when wet, attached by a narrow gelatinous holdfast, of terete, pointed filaments with numerous short, spinule-like side branches, (25-)50 µm thick in upper parts, 75-100(-110) µm thick in basal parts, forming 2-10 mm wide tufts. Thallus (in section) ecorticate, the mycobiont cells loosely paraplectenchymatous, short-celled. Apothecia sessile, c. 0.2 mm across, lateral or terminal, developing from pycnidia on swellings on the branches, with a punctiform, dark brown disc, and a thin, persistent thalline margin. Proper exciple thin or absent; epithecium brownish; hymenium gelatinous, colourless, I+ blue-green, K/I+ blue; paraphyses sparingly branched, the apices thickened; hypothecium colourless. Asci 8-spored, cylindrical-obclavate, with a very thin wall disintegrating or opening by apical ruptures, -type. Ascospores 1-celled, hyaline, globose, 4-6 µm wide. Pycnidia black, developing laterally from the filaments. Conidia bacilliform, 2.5-4 x c. 1 µm. Photobiont cyanobacterial (Stigonema), the photobiont trichomes with true branching, i.e. side branchlets formed by periclinal cell divisions in the trichome, reacting I-. Spot tests: all negative. Chemistry: without lichen substances. Note: on periodically wetted siliceous rocks above and near treeline. To be looked for in the Italian Alps.
