-like fungi within the Sordariomycetes hold significant ecological and economic importance, especially in biocontrol. This study describes two novel species, and , and provides DNA sequence data and identification keys for the genera and . The genus , known for its considerable biotechnological value, comprises endophytes characterized by sterile mycelia that produce antibiotic volatile organic compounds (VOCs). Historically, the classification of has relied on culture characteristics, VOC chemical profiles, and molecular phylogenetic analyses. However, culture characteristics and VOC profiles lack a definitive diagnostic value. Although asexual morphological traits are crucial for genus-level classification, no conidiogenous structures have been observed in . Here, we report the asexual morphological characteristics of and describe as a new record in China, supported by both its asexual morphology and molecular phylogenetic evidence.
粪壳菌纲内类似真菌具有重要的生态和经济意义，尤其是在生物防治方面。本研究描述了两个新物种， 和 ，并提供了 属和 属的DNA序列数据及鉴定检索表。 属以其相当大的生物技术价值而闻名，包含以内生菌特征为无菌菌丝体并产生抗生素挥发性有机化合物（VOCs）的真菌。从历史上看， 的分类依赖于培养特征、VOC化学图谱和分子系统发育分析。然而，培养特征和VOC图谱缺乏明确的诊断价值。尽管无性形态特征对于属级分类至关重要，但在 中未观察到分生孢子结构。在此，我们报告了 的无性形态特征，并将 描述为中国新记录种，其无性形态和分子系统发育证据均支持这一结论。
