Phylogenetic tree based on maximum likelihood (ML) analysis of a combined data set of his3, tef1, tub2 and ITS sequence alignments. Bootstrap value ≥ 60 % for maximum parsimony (MP) and ML analyses are indicated at the nodes. Bootstrap values lower than 60 % are marked with “*” and absent are marked with “–”. Isolates representing ex–type material are marked with “T” and isolates collected in this study are highlighted in bold. Calonectria brachiatica (CMW 25307) and Calonectria pauciramosa (CMW 5683) represent the outgroups.
