Tubeufiaceae, a cosmopolitan family with a worldwide distribution, is mostly reported as saprobic on decaying woody materials from both aquatic and terrestrial habitats. The family is commonly found as helicosporous hyphomycetes, while some are chlamydosporous and phragmosporous. In this study, thirteen helicosporous hyphomycetes were collected from Thailand and China. The phylogenetic analyses of combined ITS, LSU, TEF1-α, and RPB2 sequence data placed them in <i>Dematiohelicomyces</i>, <i>Helicoma</i>, <i>Helicotruncatum</i>, <i>Neohelicosporium</i>, <i>Parahelicomyces</i>, and <i>Tubeufia</i> within Tubeufiaceae. Three new species, <i>Tubeufia cocois</i>, <i>Parahelicomyces chiangmaiensis</i>, and <i>Neohelicosporium bambusicola</i>, one new host record, <i>Tubeufia laxispora</i>, and one new geographic record, <i>T</i><i>. longihelicospora</i>, are introduced based on both morphological characteristics and phylogenetic analyses. In addition, <i>Dematiohelicomyces helicosporus</i>, <i>Helicoma guttulatum</i>, <i>Helicotruncatum palmigenum</i>, and <i>Tubeufia cylindrothecia</i> are described with detailed descriptions and color photo plates.
