Abstract

<br> Helicosporous hyphomycetes are a group of fungi, characterised by coiled or spiral conidia and are known for their potential to produce bioactive secondary metabolites. During a survey of helicosporous hyphomycetes, four isolates were obtained from decaying wood in Hainan Province, southern China. Based on phylogenetic analyses of a combined dataset (ITS, LSU,<br> tef<br> 1-α and<br> rpb<br> 2) and morphological characteristics, two novel species,<br> Helicotubeufia qixianlingensis<br> and<br> Tubeufia diaoluoshanensis<br> , are introduced. Comprehensive descriptions, illustrations and phylogenetic analyses supporting the taxonomic placement of these new taxa are provided. Notably,<br> H. qixianlingensis<br> represents the first record of<br> Helicotubeufia<br> from a terrestrial habitat, thereby expanding the known diversity of tropical terrestrial fungi.<br>
