is an important order of diverse fungal pathogens, saprobes, and endophytes distributed worldwide. Recent studies of in China have discovered a broad range of species, some of which have not been formerly described. In this study, 60 saprobic isolates were obtained from decaying woody hosts in southwestern China. The isolates were compared with other species using morphological characteristics, and available DNA sequence data was used to infer phylogenetic analyses based on the internal transcribed spacer (ITS), large subunit rRNA gene (LSU), and translation elongation factor 1-α () loci. Three novel species were illustrated and described as , , and , which belong to rarely identified genera within . is the second species identified from the respective monotypic genus. The previously known species were identified as , , , , , . , . , , . , , , , , and . The results of this study indicate that numerous species of are yet to be revealed in southwestern China.
是一类重要的真菌病原体、腐生菌和内生菌，分布于世界各地。最近对中国的研究发现了种类繁多的物种，其中一些以前尚未被描述过。在本研究中，从中国西南部腐烂的木质宿主中获得了60株腐生菌分离株。利用形态特征将这些分离株与其他物种进行比较，并利用现有的DNA序列数据基于内转录间隔区（ITS）、大亚基rRNA基因（LSU）和翻译延伸因子1-α（）位点进行系统发育分析。描述并阐明了三个新物种，分别为 、 和 ，它们属于 中很少被鉴定的属。 是从各自的单型属中鉴定出的第二个物种。先前已知的物种被鉴定为 、 、 、 、 、 、 、 、 、 、 、 、 、 和 。本研究结果表明，中国西南部仍有许多 物种有待发现。
