During our investigation of saprobic fungi in southwestern China, three micro-hyphomycetous fungi were isolated from dead wood in freshwater and terrestrial habitats in Guizhou Province. Phylogenetic analyses of ITS, LSU, and SSU sequences, performed using Maximum Likelihood and Bayesian Inference methods, confirmed that these isolates belong to . Based on distinct morphological characteristics and molecular phylogenetic evidence, we describe three new species: , , and . Furthermore, the effectiveness of three DNA markers for species-level identification within was evaluated using Assemble Species by Automatic Partitioning (ASAP) analysis, which identified the ITS nucleotide sequences as the most reliable marker for species differentiation within the genus.
在中国西南部腐生真菌的调查过程中，从贵州省淡水和陆地生境的枯木中分离出三种微菌丝真菌。使用最大似然法和贝叶斯推断法对ITS、LSU和SSU序列进行系统发育分析，证实这些分离物属于 。基于独特的形态特征和分子系统发育证据，我们描述了三个新物种： 、 和 。此外，通过自动划分组装物种（ASAP）分析评估了三种DNA标记在 内物种水平鉴定中的有效性，该分析确定ITS核苷酸序列是该属内物种分化最可靠的标记。
