篮状菌属的三个中国新记录种

报道依据形态学和基于BenA、Rpb2和rDNA ITS1-5.8S-ITS2序列的分子系统学分析确定的篮状菌属篮状菌组Talaromyces sect. Talaromyces的3个中国新记录种,即蛇床篮状菌T. cnidii,苹果篮状菌T. malicola和丘陵篮状菌T. tumuli。T. cnidii生长较快,形成典型的绒状菌落,产生大量橄榄绿色分生孢子,在CYA和MEA上菌落背面呈深红色;其帚状枝为双轮生兼不规则生,分生孢子椭球形至卵形,壁光滑,大小不一。T. malicola生长适中,在CYA上形成絮状兼绳状菌落且只产生少量分生孢子,但在MEA上产生大量灰绿色分生孢子;其帚状枝主要为紧密双轮生,偶尔单轮生,分生孢子球形至近球形,壁光滑至稍粗糙。T. tumuli生长适中,形成絮状兼绳状菌落并产生大量灰绿色分生孢子;其帚状枝为双轮生兼不规则生,排列不紧密,瓶梗安瓿形,分生孢子椭球形至柠檬形,壁光滑至稍粗糙。

Three species of Talaromyces (Ascomycota,Eurotiales)new to China

Three species of Talaromyces sect. Talaromyces new to China are reported in this paper, namely T. cnidii, T. malicola and T. tumuli. They are identified by using morphology method and molecular phylogenetics based on BenA, Rpb2 and rDNA ITS1-5.8S-ITS2 sequences. T. cnidii grows relatively fast, forming typical velutinous colonies with abundant olive-green conidia en masse, showing dark red on reverse sides of CYA and MEA, producing biverticillate and irregular penicilli with ellipsoidal to ovoid, smooth-walled conidia different in size. T. malicola grows moderately and forms floccose and funiculose colonies on CYA with sparse sporulation, but with heavy sporulation on MEA, producing compact biverticillate and occasionally monoverticillate penicilli with globose to subglobose, smooth-walled to slightly roughened conidia. T. tumuli has a moderate growth rate, forming floccose and funiculose colonies with abundant grey-green conidia en masse; its penicilli are biverticillate and irregular, and loosely positioned, bearing ampuliform phialides and ellipsoidal to lemon-shaped, smooth-walled to slightly roughened conidia.
