Beauveria ist eine anamorphe Schlauchpilzgattung aus der Familie der Cordycipitaceae. Arten der Gattung Beauveria leben entomopathogen, d. h., sie parasitieren Insekten.[1] Beauveria kommt kosmopolitisch vor und vermehrt sich asexuell.[2] Eine verwandte entomopathogene Gattung ist Cordyceps.
Beauveria bassiana und B. brongniartii werden im biologischen Pflanzenschutz gegen Schadinsekten eingesetzt,[2] z. B. zur Bekämpfung von Engerlingen.[3]
Beauveria-Arten lassen sich anhand ihrer Konidien auseinanderhalten.[2]

Beauveria ni jenasi ya kuvu entomopathojeni (kuvu zisababishazo magonjwa kwa wadudu) katika familia Cordycipitaceae. Kuvu hizi hazina jinsia na ni anamorfi za spishi za Cordyceps (teleomorfi zao). Spishi za Beauveria zinazaa spora nyeupe au njano ambazo ni ndogo sana na hazichanganyiki na maji. Zinazaliwa juu ya hife kwa umbo wa zigizaga.
Spishi za Beauveria huonekana sana zikimea juu ya mizoga ya wadudu. Zinatokea pia katika udongo kila mahali pa dunia, isipokuwa Antakitiki, na hata ndani ya mimea (endofiti). Spishi kadhaa, kama Beauveria bassiana na B. brongniartii, hutumika kama dawa za kibiolojia dhidi wadudu waharibifu.
Tangu kuwadia kwa mihtasari ya jenetiki imewezekana kutambua spishi zaidi kuliko zamani. B. bassiana na B. brongnartii imeonekana kuwa michanganyiko ya spishi. Spishi mpya sita zimeeleza juzijuzi.
Spishi mbili zimewekwa katika jenasi nyingine: B. simplex inaitwa Acrodontium simplex sasa na B. nivea inaitwa Tolypocladium inflatum sasa.

Beauveria is a genus of asexually-reproducing fungi allied with the ascomycete family Cordycipitaceae.[1] Its several species are typically insect pathogens. The sexual states (teleomorphs) of Beauveria species, where known, are species of Cordyceps.
Beauveria species are white entomopathogenic fungi. They form unicellular conidia that are typically hydrophobic and very small. The conidia are formed holoblastically from basally inflated conidiogenous cells. After conidium production, the conidiogenous cell elongates before producing another conidium atop a small denticle (a narrow projection bearing a conidium or sporangium). The result is the formation of a distinctive, slender, zig-zag rachis. Colonies of Beauveria species are typically white or off-white on artificial culture media.
Species of Tritirachium resemble Beauveria species in having a zig-zag conidiogenous cells, but differ in lacking conspicuous denticles and in producing yellow-brown to purple colonies.
Beauveria species are commonly found associated with insects or habitats supporting insects, including soil and private dwellings. B. bassiana, the most widely known member of this genus, has been developed as a biological pesticide for various insect pests.
A multilocus phylogeny of Beauveria based on partial sequences of RPB1, RPB2, TEF and the nuclear intergenic region, Bloc, has been described to assess diversity within the genus and to evaluate the taxonomic status of species.[2] B. bassiana and B. brongniartii, both of which represent species complexes and which previously lacked type specimens, were redescribed and types are proposed in this paper. In addition six new species were described including B. varroae and B. kipukae, which form a biphyletic, morphologically cryptic sister lineage to B. bassiana. B. sungii is an Asian species that is linked to an undetermined species of Cordyceps. The combination B. amorpha was considered validly published; previous literature also refers to invalid B. felina and B. globulifera.
B. simplex is now Acrodontium simplex; B. nivea is Tolypocladium inflatum.

Beauveria est un genre de champignons à reproduction asexuée alliés à la famille des Ophiocordycipitaceae (ascomycete). Ses nombreuses espèces sont généralement des parasites entomopathogènes. Les stades sexués (téléomorphes) des espèces de Beauveria, sont, quand on les connait, des espèces du genre Ophiocordyceps.

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。
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。
B. simplex現名為Acrodontium simplex，而B. nivea現名則是Tolypocladium inflatum。
