Neochlamydotubeufia
Neochlamydotubeufia Y.Z. Lu, Boonmee & K.D. Hyde, in Lu et al., Fungal Diversity 92: 221 (2018).
Index Fungorum number: IF 554861; Facesoffungi number: FoF 04731, 2 morphological species (Species Fungorum 2022), 2 species with molecular data.
Saprobic on decaying wood. Sexual morph: Ascomata superficial, solitary or scattered, globose to subglobose, dark brown to black, setose, coriaceous, with a central ostiole. Ostiole single, central. Setae covering the whole ascoma, dark brown to black, taper to an acute apex, unbranched, thick-walled. Peridium composed of several layers of cells of textura angularis. Hamathecium branched, hyaline pseudoparaphyses. Asci 8-spored, bitunicate, fissitunicate, cylindrical to clavate, saccate, apically rounded, short pedicellate. Ascospores 2–3-seriate, fusiform, straight to slightly curved, tapering toward the ends, guttulate, multi-septate, not constricted at the septa, hyaline to pale brown. Asexual morph: Hyphomycetous, chlamydosporous. Chlamydospores holoblastic, broadly oval to ellipsoid, dictyoseptate, pale brown when immature, darkened to black when matured, with terminal cells round and pale brown (adapted from Lu et al. 2018).
Type species: Neochlamydotubeufia fusiformis Y.Z. Lu, Boonmee & K.D. Hyde
Notes: Neochlamydotubeufia is characterised by superficial, solitary or scattered, globose to subglobose, dark brown to black ascomata, dark brown to black setae, cylindrical to clavate, saccate asci and 2–3-seriate, fusiform, straight to slightly curved, multi-septate, hyaline to pale brown ascospores. The asexual morph is characterised by holoblastic, broadly oval to ellipsoid pale brown chlamydospores. Neochlamydotubeufia resembles Chlamydotubeufia and Dictyospora, but is phylogenetically distinct. Molecular markers available for Neochlamydotubeufia are ITS, LSU, SSU, TEF-1 and RPB2.
