摘要简单霉菌属的寄主范围广，分布广泛。有些种类与锈菌以及其他植物病原真菌有关，在生物防治中发挥重要作用。本研究从泰国清迈省采集了两株单纯孢菌。从一只感染蚁体上分离到一种新的蚁类单孢菌（Simplicillium formicae sp. nov.）lanosoniveum为新记录。最初使用ITS基因序列鉴定物种，并使用形态学结合nrLSU，nrSSU，TEF和RPB 1数据集的系统发育分析进行确认。蚁科单孢菌与该属其他种的区别在于存在瓶状的合生线和具有闰节的瓶梗。羊毛状单孢菌类似于该物种的其他集合，其完全单生，锥形瓶梗和球形至椭圆形的分生孢子附着在细长的头上。文中还提供了一个单孢菌属的种检索表。
Abstract Simplicillium species have a wide host range and an extensive distribution. Some species are associated with rusts, as well as other plant pathogenic fungi and play an important role in biological control. In this study, two specimens of Simplicillium were collected from Chiang Mai Province, Thailand. Simplicillium formicae sp. nov. was isolated from an infected ant and S. lanosoniveum from Ophiocordyceps unilateralis which is a new host record. Species were initially identified using ITS gene sequences and confirmed using morphology coupled with phylogenetic analyses of a combined nrLSU, nrSSU, TEF and RPB1 dataset. Simplicillium formicae differs from other species in the genus by the presence of flask-shaped synnemata and phialides with intercalary nodes. Simplicillium lanosoniveum resembles other collections of the species by its completely solitary, tapering phialides and globose to ellipsoidal conidia which adhere in a slimly head. A key to species of Simplicillium is also provided.
