摘　　要：在系统调查我国篮状菌属Talaromyces物种资源的工作中,分离得到了10株篮状菌。基于形态学和BenA、CaM及rDNA ITS1-5.8S-ITS2序列的分子种系学分析确定它们分属于6个种,即艾米斯托克篮状菌T.amestolkiae、暗玫瑰篮状菌T.atroroseus、暗绿篮状菌T.fuscoviridis、肯德里克篮状菌T.kendrickii、斯托尔篮状菌T.stollii和多样篮状菌T.versatilis,其中后4种为篮状菌组section Talaromyces的我国新记录种。T.fuscoviridis生长适中,在MEA培养基背面呈特征性的暗绿色,形成绒兼短絮状菌落,产生稀疏的灰色分生孢子,其帚状枝双轮生兼单轮生,瓶梗为安瓿形;T.kendrickii生长适中,产生典型绒状菌落和大量深绿色分生孢子,其帚状枝双轮生兼不规则生,排列紧密,瓶梗为安瓿形;T.stollii生长迅速,形成绒状兼絮状菌落并产生大量灰绿色分生孢子,其帚状枝双轮生兼三轮生,排列紧密,瓶梗为典型披针形;T.versatilis生长迅速,形成短絮状兼绳状菌落,产生脏粉色菌丝体和稀疏的灰色分生孢子,其帚状枝双轮生兼单轮生,排列不紧密,瓶梗为安瓿形。这4个新记录种的发现进一步丰富了我国篮状菌属的物种资源。In the survey of Talaromyces species diversity in China,ten isolates were identified as T.amestolkiae,T.atroroseus,T.fuscoviridis,T.kendrickii,T.stollii and T.versatilis,respectively,according to morphological characters and the combined phylogenetic analysis of theβ-tubulin gene,calmodulin gene and rDNA ITS1-5.8 S-ITS2 sequences.Among the six species,the latter four species belonging to section Talaromyces are new to China.T.fuscoviridis grows moderately,presenting the characteristic dark-green colony reverse on MEA,forming velutinous to compact floccose colonies with sparse grey-coloured sporulation and biverticillate and monoverticillate penicilli with ampuliform phialides;T.kendrickii also grows moderately,forming typical velutinous colonies and abundant dull-green sporulation and compact biverticillate and irregular penicilli with ampuliform phialides;T.stollii grows fast and forms velutinous and floccose colonies with abundant grey-green sporulation,bearing compact biverticillate and terverticillate penicilli with typical acerose phialides;T.versatilis grows fast and forms floccose and funiculous colonies with dirty pinkish mycelium and sparse greyish sporulation,and produces loosely positioned biverticillate and monoverticillate penicilli.
