Type species – Calyptosphaeria tenebrosa Réblová & A.N. Mill.

Notes – Calyptosphaeria, introduced by Réblová et al. (2018), was segregated from Lentomitella to accommodate C. subdenudata, C. tropica, C. tenebrosa and C. collapsa based on morphology and phylogeny. Calyptosphaeria species are saprobic and have a worldwide distribution (Huhndorf et al. 2008, Réblová et al. 2018). The genus is characterized by semi- immersed, globose to conical ascomata with ostioles and necks, 8-spored, unitunicate, cylindrical, short-pedicellate asci with J-, apical rings, and ellipsoidal to fusiform, brown, septate ascospores (Réblová et al. 2018). The asexual morph is undetermined.
