Phylogenetic tree of Calonectria species in the Sphaero-Naviculate group based on maximum likelihood (ML) analysis of combined DNA dataset of tef1, his3, cmdA and tub2 gene sequences. ML and MP (maximum parsimony) bootstrap values (ML/MP) are shown above branches, with bootstrap values below 60 % marked with an *, and absent analysis values are marked with -. Isolates representing ex-type material are marked with “T”, isolates highlighted in bold were sequenced in this study and novel species were covered in orange. The tree was rooted to Ca. pauciramosa (CMW 5683 and CMW 30823).
