【目的】调查研究被毛孢属真菌资源,丰富该属的物种多样性,完善已知种在公共数据库中的分类信息。【方法】从贵州省发现两个分别寄生于同翅目沫蝉、鳞翅目松梢螟成虫的真菌标本GZUIFR-dj14和GZUIFR-dy1,通过形态学观察和基于tef1、ITS和28S r DNA 3个基因序列的分子生物学系统发育分析对其进行鉴定。【结果】两个病原真菌被鉴定为两个已知种,分别为长白山被毛孢(Hirsutella changbeisanensis)和雷州被毛孢(Hirsutella leizhouensis)。【结论】重新描述了这两种被毛孢的标本和无性型分离菌株,对其新寄主、新栖息地进行了报道,并补充了分子序列、系统发育分析等分类信息。
【OBJECTIVE】 To investigate the genus C. cepacia and enrich the species diversity of this genus, and improve the classification information of known species in public databases. 【Method】 Two strains of fungi, GZUIFR-dj14 and GZUIFR-dy1, parasitized in adults of the Homoptera, Lepidoptera, and Lepidoptera, respectively, were found in Guizhou Province by morphological observation and based on tef1, ITS and 28S r DNA 3 A molecular sequence analysis of the molecular phylogeny of its identification. 【Result】 The two pathogenic fungi were identified as two known species, Hirsutella changbeisanensis and Hirsutella leizhouensis. 【Conclusion】 The two species of C. sphaerocephala and their anamorphic isolates were re-described. Their new hosts and new habitats were reported, and the classification information such as molecular sequence and phylogenetic analysis were supplemented.
