Host tree of fungi. Bayesian and NJ analyses of fungi showing the position of the genus Symbiotaphrina within the Ascomycota. This tree is inferred from a combined data set of nuclear SSU rDNA, LSU rDNA, and RPB 2 from 84 species of the Ascomycota with one basidiomycete species used as the outgroup. The phylogram represents the majority rule consensus tree of 40,000 post-burnin trees sampled by the Bayesian search algorithm. The lengths for each branch were averaged over all trees having this branch (sumt option in MrBayes v30b4). Numbers above internodes are posterior probabilities (when ≥95%). Values below the internodes are NJ bootstrap proportions. If both the Bayesian posterior probabilities are ≥95% and the NJ bootstrap support are ≥70%, the internal branch is shown as a thicker line. The grey box delimits the genus Symbiotaphrina (bluish green text). Supra-generic taxon names follow [49]. The major intron-containing fungal groups are shown in different colors (Acarosporomycetidae in blue, Ostropomycetidae in vermillion, Lecanoromycetidae in orange, and the Sordariomycetes in reddish purple).
