中文摘要：根据形态学和CaM、Rpb2及rDNA ITS1-5.8S-ITS2序列的分子系统学分析,界定篮状菌属岛篮状菌组Talaromycessect.Islandici的3个中国新记录种,即螨生篮状菌T.acaricola、根篮状菌T.radicus和哒叻篮状菌T.tratensis。螨生篮状菌生长局限,形成绒状菌落,在MEA上产生稀疏的灰绿色分生孢子,菌丝淡绿黄色,分生孢子梗双轮生、三轮生和不规则生,帚状枝排列较松散,瓶梗安瓿形,孢子梭形至椭球形,壁光滑。根篮状菌生长较慢,但在37℃可生长,形成致密短絮状菌落,菌丝体绿黄色,孢子稀疏,灰绿色,分生孢子梗双轮生,帚状枝排列紧密,瓶梗圆柱形至披针形,孢子椭球形,壁光滑。哒叻篮状菌生长缓慢,在25℃培养7 d后未产分生孢子,菌丝体呈浅橙黄色,产生适量橙黄色裸囊壳,子囊孢子椭球形,壁光滑至稍粗糙。

外文摘要：Three species of Talaromyces sect.Islandici new to China are reported in this paper,namely T.acaricola,T.radicus and T.tratensis,which are identified by morphological observation and molecular phylogenetics analysis based on CaM,Rpb2 and rDNA ITS1-5.8S-ITS2 sequences.Talaromyces acaricola has a restricted growth rate,forming velutinous colonies with sparse gray-green conidia en masse and pale green-yellow mycelium on MEA;it produces loosely-positioned biverticillate,terverticillate and irregular penicilli with fusiform to ellipsoidal,smooth-walled conidia.Talaromyces radicus has a low growth rate but grows normally at 37 °C,and forms compact floccose colonies with sparse,grayish conidia en masse and green-yellow mycelium;its penicilli are biverticillate and compact with cylindrical to acerose phialides and ellipsoidal,smooth-walled conidia.Talaromyces tratensis grows slowly without sporulation,producing orange-yellow mycelium and gymnothecia,and bearing ellipsoidal,smooth-walled to slightly roughened ascospores.
