摘要
为了调查我国篮状菌(Talaromyces)的物种资源,采用改进的土壤样品分离方法从青海和河南的土壤样品分离得到两株篮状菌(AS 3.15811=12260和AS 3.15848=14002).通过形态学和基于CaM和ITS的分子种系学研究确定其为蓝状菌属岛蓝状组(Talaromycessect.Islandici)的我国两个新记录种,即安拉阿巴德篮状菌(T.allahabadensis)和鸽色篮状菌(T.columbinus),它们均生长缓慢,产生绒状菌落.T.allahabadensis AS 3.15811的分生孢子稀疏,灰绿色,帚状枝排列不紧密,菌丝黄白色,瓶梗安瓿形,分生孢子柠檬形,壁光滑.T.columbinus AS 3.15848的分生孢子蓝灰色,帚状枝排列紧密,孢梗茎和梗基顶端明显膨大,分生孢子球形或梨形至椭球形,壁光滑.这两个种的发现进一步丰富了我国篮状菌物种资源储备。
In order to survey the Talaromyces species resource in China,two Talaromyces strains were discovered from soil samples from Qinghai and Henan using an improved isolation method.Based on morphological and molecular characters of CaMand ITS,the two isolates,namely AS3.15811 and AS3.15848,were identified as T.allahabadensis and T.columbinus,which are two new record species of section Islandici of Talaromyces from China.They both grow slowly and present velutinous colonies,T.allahabadensis AS3.15811 is characterized by sparse sporulation,gray-green conidia en masse,loosely-positioned metulae,yellow-white mycelium,ampuliform phialides and lemon-shaped conidia with smooth walls.T.columbinus AS3.15848 has blue-gray conidia en masse,adpressed penicilli,apically-swollen stipes and metulae,globose or pyriform to ellipsoidal conidia with smooth walls.The discovery of the two species enriched our biological species reserve.
