白僵菌屬(學名:Beauveria)是子囊菌門蟲草菌科(英语:Cordycipitaceae)[1]下的一个屬,行無性生殖。白僵菌屬下属的種通常是昆蟲的病原菌,其有性態(英语:Teleomorph, anamorph and holomorph)為蟲草屬(英语:Cordyceps)的物種,其中最出名的是冬蟲夏草。
白僵菌屬於蟲生真菌(英语:Entomopathogenic fungus),常在昆蟲体面形成微小、疏水、白色的分生孢子,由基部的產孢細胞以全芽生型(holoblastic)的方式產出,在產出第一個分生孢子後,產孢細胞要產出下一個孢子前會先延長,在頂端會留下先前產孢的突起痕跡,最終形成一個獨特、細長如拉鍊般曲折的軸狀構造。白僵菌的菌落在人工培養基上通常是白色或灰白色的。
麦轴梗霉(英语:Tritirachium)和白僵菌在產孢細胞上都有如拉鍊般曲折的軸,但頂端不會留下產孢突起的痕跡,最不同的地方是其菌落顏色為黃褐色或是紫色。
白僵菌常能在昆蟲身體上或是昆蟲休憩的棲地發現,包括在土壤或是私人住宅。球孢白僵菌(英语:Beauveria bassiana)是白僵菌屬裡最廣為人知的,在於開發成生物性除蟲劑,能有效防治多種害蟲。
分類
有研究以RPB1,RPB2,TEF和核基因間區域Bloc的部分序列確立白僵菌屬物種的多樣性,並評估物種的分類地位。[2]
巴氏蠶白僵菌(英语:Beauveria bassiana)和布氏白僵菌(英语:B. brongniartii)均為複合種(英语:species complex),過去缺乏模式標本,後來皆被重新描述並提出了模式。此外,還有六個新物種被描述,包括B. varroae和B. kipukae,它們形成巴氏蠶白僵菌的姊妹群,兩者間的外形並無差別。B. sungii是亞洲一種與未確定蟲草屬物種關聯的物種。
