Flora, 39: 284, 1856. Basionym: Arthopyrenia arthonioides A. Massal. - Ric. Auton. Lich. Crost.: 169, 1852.
Synonyms: Melanotheca arthonioides (A. Massal.) Nyl.; Pyrenula arthonioides (A. Massal.) Trevis.
Description: Thallus crustose, not lichenized, endosubstratic, usually poorly evident, causing a slight bleaching of the bark. Ascomata perithecioid, immersed into 0.4–1.3 mm long, 0.2–0.65 mm wide, 100–200 μm thick, dark brown to black, irregularly shaped pseudostromata covered in an overlying, black wall which is not continuous below the hamathecium, with 1-4 globose to subglobose locules, each with a centrally located ostiole. Hamathecium of 2-3 µm thick, branched, rarely anastomosing, non-amyloid pseudoparaphyses. Asci 8-spored, bitunicate, broadly clavate to elongate-subglobose, with an ocular chamber, and occasionally with a short-pedicel. Ascospores 1-septate, slightly constricted at septum, hyaline, elongate-ellipsoid, 10-15(-17) x 3–4.5(-5) µm, the cells of unequal size. Spot tests: all negative. Chemistry: without lichen substances.
