Phylogenetic tree.

Consensus phylogram (50% majority rule) resulting from a Bayesian analysis of the nrITS sequence alignment of Russula species, showing mean branch lengths, obtained from 106 generations of an MCMC analysis. Bayesian posterior probabilities (≥ 0.50) has been indicated above the branches. The scale bar represents number of expected changes per site. Categorizations of Russula species within the phylogenetic tree follows classification of Sarnari [42].
