Phylogeny of the genus Rubroboletus based on a Bayesian and Maximum Likelihood Inference analysis of a ITS dataset. Bayesian posterior probability values (in bold) ≥ 0.7 and maximum likelihood bootstrap (ML) values ≥ 50% are shown on the branches. Thickened branches indicate BYPP ≥ 0.95 and ML support ≥ 70%. Dashed branches indicate BYPP ≥ 0.95 and ML bootstrap support < 70%. Nodes that receive BYPP < 0.95 but with ≥ 70% ML are indicated by small black-filled squares. Newly sequenced collections are in bold. Caloboletus calopus (HM347645) was chosen as the outgroup taxon.
