摘　　要：线虫草属是线虫草科中最著名的属,以其具有显著药用价值的众多昆虫病原真菌而闻名。尽管该属已报道了许多物种,但该属的多样性仍然是个谜。在本研究中,采用综合方法对在中国采集的4个线虫草属物种进行分类鉴定,包括多基因系统发育分析(ITS、SSU、LSU、RPB1、RPB2和TEF1α)以及形态学评估,确定了它们的分类地位。本研究为这些新发现的物种提供了图解描述和分类讨论,有助于我们更深入地了解线虫草属丰富的物种多样性。Ophiocordyceps,the most prominent genus in the Ophiocordycipitaceae,is renowned for its numerous entomopathogenic species with significant medicinal value.Despite the existing descriptions of numerous species,the complete diversity of this genus remains enigmatic.In this study,four Ophiocordyceps species previously unknown in China were collected,and a comprehensive approach,including multigene phylogenetic analyses(ITS,SSU,LSU,RPB1,RPB2,and TEF1α)along with morphological assessments was employed to determine their taxonomic status.Illustrated descriptions and taxonomic discussions for these newly discovered species are provided,contributing to our understanding of the diversity within the Ophiocordyceps genus.
