Phylogenetic tree based on ML analysis of a combined DNA dataset of tef1, his3 and cmdA gene sequences for the species of Calonectria in the Sphaero-Naviculate Group. Bootstrap value ≥ 70 % for MP and ML analyses are presented at the branches. Bootstrap values lower than 70 % are marked with “*”, and absent are marked with Isolates, representing ex-type material, are marked with “T”, isolates sequenced in this study are highlighted in blue and bold. The tree was rooted to Ca. pauciramosa (CMW 5683 and CMW 30823).
