Abstract

Ophiocordyceps, a genus of invertebrate-pathogenic fungi in the family Ophiocordycipitaceae (order Hypocreales), is globally distributed. Over 300 species have been described and accepted as members of the genus. This study introduces three new Ophiocordyceps species from China: O.liaoningensis, O.muscidarum, and O.neocommunis. Remarkably, O.muscidarum, hosted on flies (Muscidae, Diptera), is characterized by its larger perithecia and longer secondary ascospores. Ophiocordycepsneocommunis is also introduced based on morphological distinctions from closely related species. Ophiocordycepsliaoningensis produces dark brown superficial perithecia with an asexual morph at the apex and does not break into part-spores. Phylogenetic analyses using six loci (LSU, ITS, SSU, tef-1α, rpb1, and rpb2) robustly support the placement of these new species within the Ophiocordyceps. Additionally, we report a new host record for Hirsutellavermicola. Detailed descriptions, illustrations, color photo plates, and a phylogenetic tree are provided.

Three蛇虫草属新种(下creales, Ophiocordycipitaceae)及中国毛癣菌寄主新记录。
蛇虫草属(Ophiocordyceps)是蛇虫草科(Ophiocordycipitaceae)的一种无脊椎致病真菌,分布于全球。超过300种已经被描述并被接受为该属的成员。本文介绍了中国虫草属3个新种:o.l aooningensis、O.muscidarum和o.n ocommunis。值得注意的是,寄生于蝇类(蝇科,双翅目)的muscidarum具有较大的周皮和较长的次生子囊孢子。根据与近缘种的形态学差异,还介绍了蛇虫草属。Ophiocordycepsliaoningensis产生深棕色的浅表包皮,顶端为无性形态,不分裂成部分孢子。利用LSU、ITS、SSU、tef-1α、rpb1和rpb2 6个基因座进行的系统发育分析有力地支持了这些新种在虫草属中的定位。此外,我们还报道了一种新的寄主记录。详细的描述,插图,彩色照片板,并提供了系统发育树。
