Phylogram of the combined genes of SSU, ITS, LSU and TEF, based on Bayesian analysis. The topology of the Bayesian tree was similar to those generated in the ML and MP analyses (Suppl. material 2: RAxML_bipartitions.comb60_ML, comb60_MPtree.nex, comb60_MrBayes.nxs.con). The numbers at each node represent the percentages of bootstrap values in ML (left) and MP (middle) calculated from 1,000 replications and the BPP (right). - indicates lack of support or support less than 50% (or 0.5 for BPP) for a particular clade. Scale bar indicates 0.1 expected changes per site.
