Phylogeny and systematics of the anamorphic, entomopathogenic genus Beauveria
Mycologia 103 (5), 1055-1073
Abstract: Beauveria is a cosmopolitan anamorphic genus of arthropod pathogens that includes the agronomically important species, B. bassiana and B. brongniartii, which are used as mycoinsecticides for the biological control of pest insects. Recent phylogenetic evidence demonstrates that Beauveria is monophyletic within the Cordycipitaceae (Hypocreales), and both B. bassiana and B. brongniartii have been linked developmentally and phylogenetically to Cordyceps species. Despite recent interest in the genetic diversity and molecular ecology of Beauveria, particularly as it relates to their role as pathogens of insects in natural and agricultural environments, the genus has not received critical taxonomic review for several decades. A multilocus phylogeny of Beauveria based on partial sequences of RPB1, RPB2, TEF and the nuclear intergenic region, Bloc, is presented and used to assess diversity within the genus and to evaluate species concepts and their taxonomic status. B. bassiana and B. brongniartii, both which represent species complexes and which heretofore have lacked type specimens, are redescribed and types are proposed. In addition six new species are described including B. varroae and B. kipukae, which form a biphyletic, morphologically cryptic sister lineage to B. bassiana, B. pseudobassiana, which also is morphologically similar to but phylogenetically distant from B. bassiana, B. asiatica and B. australis, which are sister lineages to B. brongniartii, and B. sungii, an Asian species that is linked to an undetermined species of Cordyceps. The combination B. amorpha is validly published and an epitype is designated.
