in Hyde & al., Fungal Diversity, 80: 135, 2016
Synonyms: Arthopyrenia cinereopruinosa auct. non (Schaer.) A. Massal.
Description: Thallus crustose, inconspicuous or slightly bleaching the bark, whitish grey, non-lichenized, without a prothallus. Perithecia black, circular or ellipsoid in outline, (0.2-)0.3-0.45 x 0.2-0.3(-0.4) mm, when young often covered by a thin layer of bark cells which gives them a grey-pruinose appearance. Involucrellum dimidiate, dark brown in water, K + greenish, clypeate, of compacted hyphae and bark cells; ostiole distinct, centrally located, filled with downwardly projecting periphyses: exciple 40-70 μm thick, pale brown; pseudoparaphyses stout, 1-1.5 μm thick, branched and anastomosing, the cells 8-16 μm long, often with elongate, oily vacuoles. Asci 8-spored, obovoid to suboblong, bitunicate, the tholus thickened, the ocular chamber up to 2-3 μm, apically rounded, 55-65 x 13-20 μm. Ascospores 1-septate, much constricted at septum, with somehow unequal cells, each cell with an obvious median constriction, hyaline, clavate to obovoid, with rounded apices, (14.5-)18-22(-24) x (5-)8-12 μm, with a 1-3 μm thick (in K), distinct perispore, the upper cell wider than the lower cell. Photobiont absent. Spot tests: all negative. Chemistry: without lichen substances.
