Contrasting phylogenetic relationships of three fungal clades. a) The ML phylogeny of fungi inferred from a concatenated supermatrix of 1,233 nuclear genes (609,899 amino acid sites) by Shen et al. (2017). Clade A contains only Ascoidea rubescence (Ascoideaceae) and is sister to Clade B, which has 43 species of Saccharomycetaceae, Saccharomycodaceae, and Phaffomycetaceae. Clade C consists of 11 species of Pichiaceae and 22 CUG-Ser2 species (Shen et al. 2016; Shen et al. 2017). Clade D is the outgroup consisting of 9 species. Clade A + B received 100% bootstrap support in the concatenated supermatrix analysis (Shen et al. 2017). Contrasting evolutionary relationships of three clades (A, B, and C) are shown in panels b and c, along with their bootstrap supports for clades A + B (100%) and B + C (46%).
