Phylogenetic tree of Diaporthe resulting from a Maximum-Likelihood (ML) analysis, based on the concatenated sequences from ITS, cal, his3, tef1-α and tub2 genetic regions. Numbers above the branches indicate ML bootstraps (left, ML BS ≥ 50%) and Bayesian posterior probabilities (right, BPP ≥ 0.90). The tree is rooted with Diaporthella corylina CBS 121124. Isolates from the present study are marked in blue and holotype isolates are indicated in bold.
