“…Consequently, the understanding of the taxonomic structure of Beauveria has been significantly broadened. Many species have since been described with the aid of molecular methods [ 11 , 12 , 13 , 14 , 15 , 16 , 17 ]. The most recent phylogenetic studies led to Beauveria , previously only composed of species known from asexual morphs, being expanded to include taxa previously described by sexual morphs as Cordyceps [ 16 , 18 ].…”

The distribution and genetic diversity of 91 of Beauveria isolates collected during a long-term survey in boreal forests of northern European Russia was studied. Based on morphological and sequence analysis of TEF and Bloc loci, three Beauveria spp. were identified: B. pseudobassiana, B. bassiana, and B. caledonica, with abundance of 81, 11, and 8%, respectively. Through multilocus sequencing, four haplotypes of B. bassiana and two haplotypes of B. caledonica were detected. Twelve haplotypes of B. pseudobassiana with non-random distribution were identified. Two haplotypes of B. pseudobassiana were the most abundant and widespread occurring across the whole study area, whereas others tended to be more specific to either the north or south of the study area, indicating the presence of different subpopulations. For further analysis of these putative subpopulations, southern and northern areas were separated along the boundary of the Köppen–Geiger climate zones (dfb and dfc), and the genetic structure was examined by analysis of molecular variance and spatial autocorrelation. Molecular evidence of intraspecific recombination of B. pseudobassiana and B. bassiana across northern European Russia area was indicated.

“…Accurate species identification within the entomopathogenic fungi Beauveria is crucial for disease control and prevention (Liu et al 2016). This genus has recently been circumscribed, and its taxonomy has been updated with new combinations and the description of new species based mainly on multi-locus phylogenies in the absence of diagnostic features that delimit species (Sanjuan et al 2014, Shrestha et al 2014, Kepler et al 2017, Chen et al 2017, 2018). In addition to phylogenies, other methodologies and data sets to delimit species are recommended to establish well-supported boundaries among species (Carstens et al 2013) because most researchers simply recognize distinct clades in either single- or multi-locus trees as species (Stewart et al 2014).…”

“…Although 26 species have been molecularly confirmed in Beauveria (Rehner et al 2011, Kepler et al 2017, Chen et al 2018), only 21 of these species and Beauveria sp. from Peru were used in the DNA-based delimitation methods.…”

“…The genus Beauveria is considered a cosmopolitan genus of soilborne necrotrophic arthropod-pathogenic fungi that includes ecologically and economically important species (Rehner et al 2011, Kepler et al 2017, Chen et al 2018). Morphologically, Beauveria genus have been characterized asexually by having conidiogenous cells arising from short, often one-celled, more or less swollen stalk cells, often in dense clusters, or scattered or in whorls from undifferentiated hyphae; they consist of a globose to fusiform basal part, and a geniculate, denticulate rachis.…”

“…Molecular analyses confirmed the monophyly and placement of seven species of Beauveria within Cordycipitaceae (Rehner and Buckley 2005, Sung et al 2007). More recent molecular studies based on multilocus phylogenetic analysis that included the Bloc nuclear intergenic region, internal transcribed spacer (ITS), translation elongation factor-1α ( TEF ), and RNA polymerase II largest subunit ( RPB 1) and second largest subunit ( RPB 2) demonstrated that Beauveria is composed of 26 species (Rehner et al 2011, Sanjuan et al 2014, Kepler et al 2017, Chen et al 2018). These phylogenetic studies also revealed that the most commonly reported species, namely, B. bassiana and B. brongniartii , encompass cryptic lineages with worldwide distributions (Rehner et al 2006, 2011, Ghikas et al 2010).…”

The genus Beauveria is considered a cosmopolitan anamorphic and teleomorphic genus of soilborne necrotrophic arthropod-pathogenic fungi that includes ecologically and economically important species. Species identification in Beauveria is difficult because of its structural simplicity and the lack of distinctive phenotypic variation. Therefore, the use of multi-locus sequence data is essential to establish robust species boundaries in addition to DNA-based species delimitation methods using genetic distance, coalescent, and genealogical concordance approaches (polyphasic approaches). In this regard, our study used multilocus phylogeny and five DNA-based methods to delimit species in Beauveria using three molecular makers. These polyphasic analyses allowed for the delimitation of 20–28 species in Beauveria, confirming cryptic diversity in five species (i.e. B. amorpha, B. bassiana, B. diapheromeriphila, and B. pseudobassiana) and supporting the description of B. peruviensis as a new taxon from northeastern Peru. The other five species were not evaluated as they did not have enough data (i.e. B. araneola, B. gryllotalpidicola, B. loeiensis, B. medogensis, and B. rudraprayagi). Our results demonstrate that the congruence among different methods in a polyphasic approach (e.g. genetic distance and coalescence methods) is more likely to show reliably supported species boundaries. Among the methods applied in this study, genetic distance, coalescent approaches, and multilocus phylogeny are crucial when establishing species boundaries in Beauveria.
