The phylogenetic tree of Simplicillium and Leptobacillium was inferred from nrSSU sequence, based on the Bayesian inference and the maximum likelihood analyses. Each value at a node indicates a bootstrap proportion (the left) and Bayesian posterior probability (the right). The scale bar 0.005 indicates the number of expected mutations per site. The species in bold black font of the Simplicillium and Leptobacillium were from this study. B. brongniartii ARSEF 617 was designated as outgroup.
