Type speciesPhaeoappendicospora thailandensis Q.R. Li, Senan. & K.D. Hyde

NotesPhaeoappendicospora was introduced in Diaporthales genera incertae sedis. The genus has been introduced based on Phaeoappendicospora thailandensis, obtained from a dead branch of Quercus sp. The species resembles Hapalocystis berkeleyi (Sydowiellaceae). It did not, however, cluster with any Hapalocystis taxa nor with any family in the Diaporthales, which resulted to its being classified as genera incertae sedis (Senanayake et al. 2017b). Crous et al. (2019b) introduced Phaeoappendicosporaceae for this genus with Neophaeoappendicospora. The genus is characterised by brown and small ascospores. Phaeoappendicospora thailandensis is illustrated in this entry.
