Microthyriaceae is typified by the sexual genus , with eight asexual genera. Three interesting isolates were collected during our investigation of freshwater fungi from the wetlands in Guizhou Province, southwest China. Three new asexual morphs are identified. Phylogenetic analyses using ITS and LSU gene regions revealed the placement of these isolates in Microthyriaceae (Microthyriales, Dothideomycetes). Based on the morphology and phylogenetic evidence, two new asexual genera, and , and three new species, , , and are introduced. Descriptions and illustrations of the new taxa are provided, with a phylogenetic tree of Microthyriales and related taxa.
小盾壳霉科以有性属为代表，有八个无性属。在中国西南部贵州省湿地淡水真菌调查过程中收集到了三株有趣的分离物。鉴定出了三个新的无性形态。使用ITS和LSU基因区域进行的系统发育分析揭示了这些分离物在小盾壳霉科（小盾壳霉目，座囊菌纲）中的位置。基于形态学和系统发育证据，引入了两个新的无性属，即 和 ，以及三个新物种，即 、 和 。提供了新分类单元的描述和图示，以及小盾壳霉目和相关分类单元的系统发育树。
