Saprobic on decaying wood or other plant materials. Sexual morph: Ascomata astromatic, leathery to fragile, dark brown to black, solitary or usually aggregated in circular to oval nests or in short rows, globose to subglobose, glabrous or roughened, with elongate necks, venter or neck are sparsely covered with a pubescence that disappears with age. Necks cylindrical, central or lateral, straight to slightly flexuous, when in circular groups decumbent to perpendicular, covering, piercing the periderm in a group. Ostiole periphysate. Peridium two-layered. Paraphyses abundant, persistent, cylindrical, unbranched, septate, constricted at the septa, tapering to the apex. Asci 8-spored, unitunicate, clavate or cylindrical, tapering towards the pedicel, with a distinct or indistinct, refractive, J-, apical ring, floating freely in centrum at maturity. Ascospores 1- or 2-seriate, hyaline to pale brown, oblong to ellipsoid, subcylindrical, reniform, straight, sometimes curved, allantoid, U- to horseshoe-shaped or 3/4 circular, aseptate or septate, not- or slightly constricted at the septum, smooth-walled. Asexual morph: Hyphomycetous, ramichloridium- and sporothrix-like. Conidiophores semi-micronematous to macronematous, unbranched or branched, cylindrical to flask- or irregularly-shaped, brown or hyaline. Conidiogenous cells polyblastic, integrated, terminal, sympodially elongating with several denticles or forming rachis producing conidia holoblastically. Conidia ellipsoidal to suballantoid, straight or curved, unicellular, hyaline (adapted from Réblová 2007, Réblová et al. 2015c, Zhang et al. 2017a).
Notes – Barbatosphaeriaceae was introduced by Zhang et al. (2017a) with three genera, Barbatosphaeria, Ceratostomella and Xylomelasma, in Diaporthomycetidae genera incertae sedis. The family formed a strongly supported, distinct clade, with a stem age of ca 110 MYA in the MCC tree (Hyde et al. 2017a, Zhang et al. 2017a). Barbatosphaeriaceae formed a sister clade to Natantiella ligneola and Ophiostomatales in Zhang et al. (2017a), while it was a sister group to Amplistromatales, Ophiostomatales and Phomatosporales in Senanayake et al. (2016). In this entry, the sexual morph of Barbatosphaeria varioseptata and the ramichloridium- and sporothrix-like asexual morphs of B. barbirostris are illustrated.
Type genus: Barbatosphaeria Réblová, Mycologia 99(5): 727 (2008) [2007].
