Classification: Barbatosphaeriaceae, Incertae sedis, Diaporthomycetidae, Sordariomycetes, Pezizomycotina, AscomycotaFungi 

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. 2015c). Zhang et al. (2017a) 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. (2015c). Ramichloridium- and sporothrix-like asexual morphs have been observed regularly in cultures of various species (Samuels & Candoussau 1996, Réblová 2007, Réblová et al. 2015c). 

Type species: Barbatosphaeria barbirostris (Dufour) Réblová, Mycologia 99(5): 727 (2008) [2007].

Other accepted species: Species Fungorum – search Barbatosphaeria.
