Phylogram of Diaporthe resulting from a Maximum Likelihood analysis, based on combined ITS, cal, his3, tef1 and tub2. Numbers above the branches indicate ML bootstraps (left, ML BS ≥ 50%) and Bayesian Posterior Probabilities (right, BPP ≥ 0.9). The tree is rooted with Diaporthella corylina. Isolates in the current study are in blue. “-” indicates ML BS < 50% or BI PP < 0.9.
