Beltraniella was introduced by Subramanian (1952) with the type species B. odinae Subram. Thirty species are accepted (Lin et al. 2017bCrous et al. 2020Hyde et al. 2020a2020bTan & Shivas 2022Species Fungorum – search Beltraniella). When present, the setae of Beltraniella species are sterile extensions of conidiophores or occur among conidiophores They are unbranched and arise from radially-lobed basal cells. Conidiophores are branched, often with setiform apex, arising from radially-lobed basal cells. Conidiogenous cells are polyblastic, sympodial, with or without swollen separating cells, and produce acropleurogenous, turbinate or biconic conidia with a distinct hyaline transverse band (Lin et al. 2017aHyde et al. 2020b). This genus was placed in the family Beltraniaceae (Amphisphaeriales, Xylariomycetidae, Sordariomycetes) (Wijayawardene et al. 2022). Some species of Beltraniella have been identified as pathogens, e.g., B. vateriae K. Swapna, Nagaveni, Kunwar & Manohar. (Priya et al. 2011). Pseudomassaria carolinensis M.E. Barr & Hodges, which was previously reported to have a Beltraniella asexual morph, was synonymized under the new combination B. carolinensis by Jaklitsch et al. (2016) based on a phylogenetic analysis.

Type species: Beltraniella odinae Subram.

Other accepted species: See Species Fungorum, search Beltraniella for names.
