Entomopathogenic fungi are ubiquitous in tropical rainforests and feature a high level of diversity. This group of fungi not only has important ecological value but also medicinal value. Nevertheless, they are often ignored, and many unknown species have yet to be discovered and described. The present study aims to contribute to the taxonomical and phylogenetic understanding of the genus by describing three new species collected from Guizhou and Yunnan Provinces in China and Krabi Province in Thailand. The three novel species named , and share similar morphologies as those in the genus , containing solitary, simple, fleshy stroma, completely immersed perithecia and cylindrical asci with thickened caps and filiform ascospores that often disarticulate at maturity. Phylogenetic analyses of combined LSU, SSU, TEF1-α, RPB1, RPB2, and ITS sequence data confirm their placement in the genus In this study, the three entomopathogenic taxa are comprehensively described with color photographs and phylogenetic analyses. A synopsis table and a key to all treated species of are also included.
昆虫病原真菌在热带雨林中普遍存在且具有高度的多样性。这一类真菌不仅具有重要的生态价值，还具有药用价值。然而，它们常常被忽视，许多未知物种尚未被发现和描述。本研究旨在通过描述从中国贵州省和云南省以及泰国甲米府采集的三个新物种，为该属的分类学和系统发育学认识做出贡献。这三个新物种分别命名为 、 和 ，它们与该属中的物种具有相似的形态特征，包括单个、简单、肉质的子座，完全埋生的子囊壳以及具加厚帽和丝状子囊孢子的圆柱形子囊，子囊孢子在成熟时常常脱节。对 LSU、SSU、TEF1-α、RPB1、RPB2 和 ITS 序列数据进行联合系统发育分析，证实了它们在该属中的分类地位。在本研究中，通过彩色照片和系统发育分析对这三个昆虫病原分类单元进行了全面描述。还包括一个概述表和该属所有已处理物种的检索表。
