is an asexual and hyphomycetous genus in the family Torulaceae. species are generally saprophytic. They have a worldwide distribution and abound in humid or freshwater habitats. In order to better understand this genus, we carried out several field collections from Sichuan, China. As a result, we obtained nine isolates from dead woody substrates in terrestrial and freshwater habitats. Based on a biphasic approach of morphological examination and multi-locus phylogenetic analyses (ITS, SSU, LSU, TEF, RPB2), these collections were identified as belonging to seven species. Four of them were new species (, , and ), and the other three belonged to existing species, though one was found for the first time in China (). Morphological and updated phylogenetic delamination of the new discoveries is also discussed. This study provides further insights into our understanding of wood-based species in China.
是刺盘孢科中的一个无性、丝孢纲属。该属物种通常为腐生菌。它们分布于世界各地，在潮湿或淡水生境中大量存在。为了更好地了解这个属，我们在中国四川进行了多次野外采集。结果，我们从陆地和淡水生境的枯木基质中获得了9个分离株。基于形态学检查和多位点系统发育分析（ITS、SSU、LSU、TEF、RPB2）的双相方法，这些采集物被鉴定为属于7个物种。其中4个是新物种（、、和），另外3个属于现有物种，不过有一个是在中国首次发现（）。还讨论了新发现物种的形态学和更新后的系统发育分层。这项研究为我们对中国木基物种的理解提供了进一步的见解。
