Index Fungorum number: IF 825364; MycoBank number: MB 825364; Facesoffungi number: FoF 06856; 2 species.
Biotrophic on living leaves or saprotrophs on decaying plant materials. Sexual morph: Pseudostromata dark brown to black, subepidermal on living leaves, also present in the saprobic state. Ascomata perithecial, globose to subglobose or pyriform, wall heavily pigmented, ostiolate. Ostiole comprising many thin, filiform periphyses. Paraphyses filiform. Asci 8-spored, unitunicate, thin-walled, cylindrical to subclavate or ellipsoidal. Ascospores ellipsoidal to cylindrical, aseptate to 1- septate, dark brown. Asexual morph: Undetermined (adapted from Guterres et al. 2019).
Type genus – Phaeochorella (Henn.) Theiss. & Syd.
Notes – Phaeochorellaceae has been introduced based on two genera, namely, Phaeochorella and Phaeoappendicospora (Guterres et al. 2019). The former genus was initially accommodated in Phyllachoraceae (Phyllachorales) only based on morphology since no species had molecular data. The acquisition of DNA sequence data for Phaeochorella parinarii was instrumental since a multi-gene phylogeny confirmed the placement of the genus in Diaporthales, forming a sister clade with Phaeoappendicospora thailandensis. Since the two genera formed a distinct clade, phylogenetically distant from other sister clades, the new family Phaeochorellaceae was established (Guterres et al. 2019). Crous et al. (2019b) later introduced the family Phaeoappendicosporaceae to accommodate Phaeoappendicospora with a new genus Neophaeoappendicospora.
