Barbatosphaeria Réblová, Mycologia 99(5): 727 (2008)
Index Fungorum number: IF505954; 9 morphological species (Species Fungorum 2020), 8 species with sequence data.
Type species – Barbatosphaeria barbirostris (Dufour) Réblová
Notes – The genus was introduced by Réblová (2007) based on Barbatosphaeria barbirostris and defined as a well-supported monophyletic clade in Sordariomycetidae, genera incertae sedis (Réblová et al. 2015). Zhang et al. (2017) transferred the genus to the newly described Barbatosphaeriaceae based on a stable clade in phylogenetic and MCC trees. A key to species accepted in the genus was provided by Réblová et al. (2015). Ramichloridium– and sporothrix-like asexual morphs have been observed regularly in cultures of various species (Samuels & Candoussau 1996, Réblová 2007, Réblová et al. 2015).
