Type species: Dematiohelicomyces helicosporus (Boonmee, Y.Z. Lu & K.D. Hyde) Y.Z. Lu, Fungal Diversity 92: 159 (2018).
≡ Chlamydotubeufia helicospora Boonmee, Y.Z. Lu & K.D. Hyde, in Hyde et al., Fungal Diversity 80:123 (2016).
Notes: Dematiohelicomyces was introduced based on morphological and phylogenetic analyses. Dematiohelicomyces resembles Helicomyces in having short conidiophores that are 0–3-septate, and helicoid conidia, having a spathulate basal end cell, but can be distinguished by its brown conidiophores (Lu et al. 2018b).
