Saprobic or endophytic on various host plants. Sexual morph: Ascomata solitary, superficial, comprising black, subglobose, carbonaceous, dome-shaped, raised, blister-like areas, within the plant tissues, flattened at the base, ostiole central. Peridium outer cells merging with the host epidermal cells, composed of dark brown to black cells of textura angularis. Paraphyses numerous, hyaline, hypha-like, septate, longer than asci. Asci 8-spored, unitunicate, cylindrical, longpedicellate, with a J-, wedge-shaped, subapical ring. Ascospores fasciculate, hyaline or paleyellowish in mass, spiral, filiform, straight or curved, aseptate, ends rounded, with or without polar mucilaginous appendages. Asexual morph: Undetermined (adapted from Konta et al. 2017).

Notes: The family was introduced by Konta et al. (2017) in Chaetosphaeriales with support from the analysis of combined LSU and ITS sequence data. In this study, a new species, Leptosporella elaeidis, is introduced.

Type species: Leptosporella Penz. & Sacc.
