, a genus with rich morphological and ecological diversity in Bionectriaceae, has a wide distribution among diverse habitats.
In the present study, a phylogenetic framework is reconstructed for the family Bionectriaceae focusing on through increased taxon-sampling using the nr sequence. Through surveying in China, Vietnam, and Thailand over the past 3 years, seven spp. were found and identified. Two new species, and are described and illustrated based on morphological characteristics and molecular data. The phylogenetic positions of the seven species were evaluated based on four genomic loci (ITS, nr, , and ).
Moreover, the genetic divergence comparisons of species for three markers (ITS, , and ) are also provided. The results indicated that the sequence data provided the best resolution for distinguishing species of , followed by sequence data for the and ITS regions.
在肉座菌科中，[属名]具有丰富的形态和生态多样性，在不同生境中广泛分布。
在本研究中，通过使用nr序列增加分类群抽样，以[属名]为重点，重建了肉座菌科的系统发育框架。在过去3年中，通过对中国、越南和泰国的[属名]进行调查，发现并鉴定了7个[属名]物种。基于形态特征和分子数据，描述并图示了两个新物种，[新物种1名称]和[新物种2名称]。基于四个基因组位点（ITS、nr、[位点3名称]和[位点4名称]）评估了这七个物种的系统发育位置。
此外，还提供了[属名]物种三个标记（ITS、[标记2名称]和[标记3名称]）的遗传差异比较。结果表明，[标记名称]序列数据在区分[属名]物种方面提供了最佳分辨率，其次是[标记2名称]和ITS区域的序列数据。
