Phylogenetic tree of the Colletotrichum boninense complex constructed using multi-gene sequences (ITS, act, tub2, gapdh, chs-1, his3 and cal). Support values at the nodes indicate a maximum likelihood (ML) of > 60% and Bayesian posterior probability (BYPP) of > 0.70. The outgroup is C. euphorbiae CBS 134752, COAD 3300, and Col-170. The strains used are GUCC 24-0193, GUCC 24-0194 and GUCC 24-0195, with a scale bar of 0.04.
