Colonies of Beauveria species are typically white or off-white on artificial culture media.

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.

In addition six new species were described including B. varroae and B. kipukae, which form a biphyletic, morphologically cryptic sister lineage to B. bassiana.

The combination B. amorpha was considered validly published; previous literature also refers to invalid B. felina and B. globulifera.
