Description: Thallus crustose, thin, effuse, membrane-like or of convex to flat areoles up to 0.4 mm diam., with a c. 25 μm thick, colourless epinecral layer; hyphae of the photobiont layer K/I+ blue. Perithecia 0.3-0.7 mm across, immersed in the thallus, or with only the dark brown ostioles protruding, dispersed, globose to broadly pyriform. Exciple 50-70 μm thick, brownish in upper part, pale or colourless below; paraphysoids 0.5-1.5 thick, persistent, delicate, branched and anastomosing; hymenial gel I-, K/I-. Asci 2-4-spored, cylindrical, fissitunicate, thick-walled, the inner wall thinner than the outer one, the apex with an internal beak, K/I-. Ascospores strongly muriform, at first colourless, then pale brown, elongate-ellipsoid to subcylindrical, 60-110 x 20-27 μm, the outer wall scarcely thicker than the septa. Photobiont chlorococcoid, the algal cells without a gelatinous sheath. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
Note: a holarctic lichen found on moribund pleurocarpous mosses on rocks and soil, more rarely on the basal parts of old trunks, with optimum in the montane belt.
