Barbatosphaeria Réblová, Mycologia 99(5): 727 (2008) [2007]

Diaporthomycetidae families incertae sedis, Barbatosphaeriaceae, Barbatosphaeria

Index Fungorum number: IF 505954; 9 morphological species (Species Fungorum 2020), 8 species with sequence data.


Saprobic on decaying wood. Sexual morph: Ascomata immersed to erumpent, aggregated in circular groups, rarely solitary, non-stromatic, dark brown to black, ostiolate. Necks cylindrical, converging when in circular groups, protruding through host surface, decumbent to perpendicular, with venter lying horizontally, sparsely clothed with dark olive to red-brown pubescence when immature. Ostiole periphysate. Peridium 2-layered, leathery to fragile, Paraphyses longer than the asci, numerous, persistent. Asci originating from croziers on elongating ascogenous hyphae, floating freely in the centrum when mature, unitunicate, 8-spored, clavate in sporiferous part, tapering toward the pedicel. Ascospores hyaline, allantoid or ellipsoid or oblong to subcylindrical, straight, at times curved, U-to horseshoe-shaped or 3/4 circular, aseptate or 1- to multi-septate. Asexual morph: ramichloridium- or sporothrix-like (adapted from Réblová et al. 2015).



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



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