Dictyospora thailandica, Helicomyces colligatus, H. torquatus, Neohelicosporium guangxiense, N. hyalosporum, N. parvisporum, Thaxteriellopsis lignicola, Tubeufia aquatica, T. chiangmaiensis, T. cylindrothecia, T. filiformis, T. guangxiensis, T. laxispora, T. parvispora, T. roseohelicospora and T. tectonae. The taxonomy of Helicoma, Helicomyces and Helicosporium is revisited based on phylogenetic analyses and morphological evidence. Neorhamphoria is transferred to Bezerromycetaceae. Three species are excluded from the genus Chlamydotubeufia, twelve species from Helicoma, four species from Helicomyces, 25 species from Helicosporium, six species from Neoacanthostigma and one species from Tubeufia. A multi-gene phylogenetic tree based on maximum likelihood and Bayesian analyses of ITS, LSU, RPB2 and TEF1α sequence data of species of Tubeufiales is provided. Detailed descriptions and illustrations are provided, as well as the morphological comparison with similar taxa are explored. The checklist of accepted Tubeufiales species and re-organised Tubeufiales species are provided.
