摘要：
Seven new collections of sexual and asexual morphs of Tubeufiaceae from woody substrates in freshwater, were obtained from different regions of Thailand. ITS, LSU and TEF1 alpha sequence data obtained from single spore isolates of these collections were analyzed with other species of Tubeufiaceae. The phylogenetic analyses with combined ITS, LSU and TEF1 alpha data indicated that the collections represented three new species, Chlamydotubeufia aquatica, Dictyospora thailandica and Helicosporium flavum. A new genus, Dictyospora is introduced to accommodate Dictyospora thailandica. Morphological descriptions and illustrations are provided for the new taxa and compared with similar taxa. A single ascospore isolates of Dictyospora thailandica and Helicosporium flavum produced asexual conidia in MEA.
