Parasitic on leaves. Sexual morph: Ascomata perithecial, densely gregarious, penetrated, globose to subglobose, black, coriaceous to membranaceous, glabrous, collapsing when dry, ostiolate, periphysate. Peridium composed of membranaceous, olivaceous brown to hyaline cells of textura intricata to textura angularis to textura prismatica. Paraphyses absent. Asci 8-spored, unitunicate, cylindrical to clavate, pedicellate, apex rounded, apical ring indistinct, evanescent. Ascospores bi-seriate, hyaline, ellipsoidal to fusiform, straight or slightly curved, 2–4-septate, smooth-walled, guttulate. Asexual morph: Undetermined (adapted from von Höhnel 1918).
Notes – The monotypic Miyakeomyces was found to be parasitic on leaves of Phyllostachys (Hara 1913). von Höhnel (1918) observed that M. bambusae makes the leaf yellow and thick, and its fruiting bodies appear on both sides of the leaf.
Type species: Miyakeomyces bambusae Hara [as ‘Miyakeamyces’], Bot. Mag., Tokyo 27(no. 317): (248) (1913).
