Two novel species within the family Dictyosporiaceae are described and illustrated from terrestrial habitats on dead culms of bamboo and an unidentified plant, respectively. Through morphological comparisons and the multi-locus phylogenetic analyses of combined LSU, ITS, SSU, and sequence dataset, two species, , are identified. Phylogenetically, both species clustered into a monophyletic clade with strong bootstrap support. can be distinguished from other species within the genus based on its almost straight ascospores. differs from other species in its conidiogenous cells intermixed with paraphyses, longer conidiogenous cells and larger conidia. The identification of this lineage contributes to our understanding of the classification of Dictyosporiaceae.
分别从竹茎和一种未鉴定植物的枯茎上的陆生栖息地描述并说明了座盘孢科内的两个新物种。通过形态学比较以及对LSU、ITS、SSU组合序列数据集的多位点系统发育分析,鉴定出了两个物种,即[物种名称1]和[物种名称2]。在系统发育上,这两个物种聚为一个具有强自展支持的单系分支。[物种名称1]因其几乎直的子囊孢子可与该属内的其他物种区分开来。[物种名称2]在其产孢细胞与侧丝混合、产孢细胞更长且分生孢子更大方面与其他物种不同。这一谱系的鉴定有助于我们对座盘孢科分类的理解。
