Synonyms: Arthopyrenia crombei A.L. Sm.; Metasphaeria cerasi (Schrad.) Vain.; Pseudosagedia cerasi (Schrad.) M. Choisy; Pyrenula cerasi (Schrad.) Trevis.; Spermatodium cerasi (Schrad.) Trevis.; Verrucaria epidermidis var. cerasi (Schrad.) Ach.
Description: Thallus crustose, mostly endosubstratic, inapparent or appearing as a paler patch on the bark, non-lichenized. Perithecia black, usually ellipsoid in outline, 0.3-0.5 x 0.2-0.4 mm, the ostiole distinct, centrally located. Involucrellum dimidiate, dark brown in water, K+ greenish, of compacted hyphae and bark cells; exciple thin, colourless to pale brown, surrounding the centrum; pseudoparaphyses persistent, slender, simple or sparingly branched, 1.5-2 μm thick, the cells c. 8-14 μm long; downwardly projecting periphysoids present near the ostiole. Asci 8-spored, cylindrical-clavate, fissitunicate, with two functional wall layers, 60-75 x 14-18 μm, with biseriately arranged spores. Ascospores 3-septate, more or less constricted at septa, especially the median one, hyaline, clavate or obovoid with rounded apices, (15-)17-22(-23) x 5-7 μm, surrounded by a c. 2 μm thick (in K), distinct perispore. Pycnidia black, 80-120 μm across, with either macro- or microconidia; macroconidia 3-septate, hyaline, oblong, 11-13 x 2-3 μm; microconidia filiform, 9-14 x c. 0.8 μm. Photobiont absent. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
