Phylogenetic tree based on maximum likelihood (ML) analysis of a combined DNA data set of ACT, CMDA, HIS3, RPB2, TEF1 and TUB2 sequences for Calonectria spp. Bootstrap values ≥ 70% for ML analyses and posterior probabilities values ≥ 0.90 obtained from Bayesian inference (BI) are indicated at the nodes as ML/BI. Bootstrap values < 70% or probabilities values < 0.90 are marked with “*”, and nodes lacking the support values are marked with “−”. Isolates representing ex-type material are marked with “T”. Curvicladiella cignea (isolate CBS 109167 and CBS 109168) represents the outgroup.
