Ric. Auton. Lich. Crost.: 164, 1852.
Synonyms: Arthopyrenia coryli (A. Massal.) Müll. Arg.; Mycopyrenula coryli (A. Massal.) Vain.; Verrucaria coryli (A. Massal.) Nyl.
Description: Thallus crustose, not lichenized, more or less immersed in the bark or inapparent, continuous, smooth, pale grey, without pseudocyphellae. Perithecia black, 0.2-0.3 mm across and c. 0.1-0.2 mm high, with a laterally extending, brown-black involucrellum. Exciple pale brown throughout, not continuous below the perithecial cavity; hamathecium of branched and anastomosed periphysoids, later substituted by more or less unbranched paraphyses; ostiole with periphyses; hymenium colourless, without anthraquinones, the hymenial gel K+ yellowish. Asci 8-spored, narrowly cylindrical, long-stalked, bitunicate, with tholus, thickened at apex with an internal apical beak, non-amyloid. Ascospores 3-septate, brown, thick-walled, narrowly ellipsoid, 10-17 x 4-6 μm. Pycnidia black. Conidia thread-like, c. 20 x 0.5 μm. Photobiont absent. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: unidentified substances in thallus.
