 Index Fungorum number: IF 25073; Facesoffungi number: FoF 12455, 4 morphological species (Species Fungorum 2022), no molecular data available.

Saprobic on host. Sexual morph: Perithecia globose, immersed, black. Paraphyses gelatinous glued together. Ascospores in flattened asci-clavate numerous, ellipsoid, simple, black dots. Asexual morph: Unknown (adapted from Eriksson and Hawksworth 1986).

 Type species: Rosellinula haplospora (Th. Fr. & Almq.) R. Sant.
