Begerowomyces Q.M. Wang & F.Y. Bai gen. nov.

Index Fungorum number: MB 828827; Facesoffungi number: FoF

Etymology: the genus is named in honour of Dr. Dominik Begerow for his contributions to yeast taxonomy and his pro- posal of the order Cystobasidiales.

This genus is proposed for the branch represented by strain CGMCC 2.3164, which formed a separate clade. Member of the Cystobasidiales (Cystobasidiomycetes). The genus is mainly circumscribed by the phylogenetic analysis of the seven genes dataset, in which it occurred as a separate branch within the Cystobasidiales (Fig. 4).

Sexual reproduction not known. Colonies yellow, butyrous. Budding cells present. Pseudohyphae and hyphae not produced. Ballistoconidia not formed.

Type species: Begerowomyces foliicola Q.M. Wang, F.Y. Bai & A.H. Li.

Fig. 4. Phylogenetic tree inferred using the combined sequences of RPB1, RPB2, TEF1, CYTB, SSU rDNA, LSU rDNA D1/D2 domains and 5.8S rDNA, depicting the phylogenetic positions of new taxa (in bold) within Pucciniomycotina. The tree backbone was constructed using maximum likelihood analysis. Bootstrap percentages of maximum likelihood analysis over 50 % from 1 000 bootstrap replicates and posterior probabilities of Bayesian inference above 0.9 are shown respectively from left to right on the deep and major branches. Bar = 0.2 substitutions per nucleotide position. Note: ns, not supported (BP < 50 % or PP < 0.9); nm, not monophyletic. The new taxa are in bold.
