Phylogeny of Polyporus and related genera inferred from ITS+nLSU+EF1-α+mtSSU+ β-tubulin+RPB1+ RPB2+nSSU data.
Topology is from ML analysis with maximum likelihood bootstrap support values (≥50, former), parsimony bootstrap support values (≥50, middle) and Bayesian posterior probability values (≥0.95, latter). The bold species are new from China.
