MycoBank number: MB 554759; Index Fungorum number: IF 554759; Facesoffungi number: FoF 04385; – 3 morphological species (Species Fungorum 2020), 3 species with molecular data.
Type species: Helicotubeufia guangxiensis Y.Z. Lu & J.K. Liu, Mycosphere 9(3): 500 (2018).
Notes: Helicotubeufia was introduced based on phylogenetic and morphological evidence to accommodate three species, the type species H. guangxiensis, H. hydei, and H. jonesii. Helicotubeufia is characterized by subglobose to ellipsoidal-ovate, dark brown to black ascomata, and cylindrical asci with hyaline fusiform, slightly curved ascospores, and hyphomycetous helicosporous asexual morphs (Liu et al. 2018).
