【 摘 要 】

Chaetosphaeriaceae is a genera-rich and highly diverse group of fungi with a worldwide distribution in terrestrial and aquatic habitats. Eight fresh collections of Chaetosphaeriaceae were obtained during investigations of hyaline-spored hyphomycetes in China and Thailand. Based on morphological characteristics and phylogenetic analysis of a combined LSU and ITS sequence dataset, Chaetosphaeria obovoidea, Codinaea aseptata, Codinaeella hyalina, Dictyochaeta guizhouensis and Paragaeumannomyces guttulatus were introduced as new species, Codinaea terminalis was reported as new host record, and Codinaea dwaya and Phialosporostilbe scutiformis were introduced as new collections. Phylogenetic analysis in this study revealed that Chaetosphaeria was polyphyletic. Detailed descriptions and illustrations of new taxa and identified species are provided, as well as an updated phylogenetic tree to confirm the placements of these eight new collections.
