Description: Thallus crustose, more or less immersed in the bark, continuous, smooth, mostly silvery white to rarely very pale yellow-brown, without pseudocyphellae. Perithecia black, (0.3-)0.4-0.5(-0.7) mm across, slightly flattened in section, forming projections on the thallus, with a black involucrellum which is separable from the exciple and slightly spreading in lower part. Exciple brown throughout; hamathecium of branched and anastomosed periphysoids, later substituted by more or less unbranched paraphyses; ostiole with periphyses; hymenium colourless, not containing anthraquinones, K-. Asci 8-spored, narrowly cylindrical, long-stalked, bitunicate, with tholus, thickened at apex with an internal apical beak, non-amyloid. Ascospores 3(-5)-septate, brown, thick-walled, narrowly ellipsoid to subfusiform, (9-)17-25(-30) x (5-)6-8(-11) μm. Pycnidia black. Conidia thread-like, curved, 10-20 x 0.5-0.8 μm. Photobiont trentepohlioid. Spot tests: thallus K+ yellow, C-, KC-, P-, UV-. Chemistry: thallus with unidentified substances.Note: a temperate species of smooth bark, most frequent on Carpinus and Fagus in open, humid woodlands.
