Apothecia biatorine, dark brown to black, 0.2-0.5 mm across, with a flat to slightly convex, rough disc, and a thin, finally excluded proper margin. Proper exciple well-developed, 35-45 µm thick, brown to olive in outer part, colourless within, of parallel hyphae, K+ brownish; epithecium greenish brown to olive, K-, N-; hymenium colourless, 50-60 µm high, I+ blue; paraphyses free, simple or sparingly branched in upper part, 0.5-1 µm thick, not thickened at apex; hypothecium thick, pale yellow. Asci 100-200-broadly clavate, thickened in upper part, without a gelatinous outer layer, the wall and well-developed apical dome strongly K/I+ blue. Ascospores 1-celled, hyaline, globose, 2-4 µm wide. Pycnidia sessile to short-stalked, reddish brown to black. Conidia broadly ellipsoid to globose, 1.5-2 µm wide. Photobiont chlorococcoid, with ellipsoid cells. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
