Escovopsis phylogeny based on EF-1 alpha sequencedata. Each branch is labeled with likelihood bootstrap values (above), Bayesian posterior probabilities (below, left) and parsimony bootstrap values (below, right). Unlabeled branches have values of less than 50 for at least two analyses of support. * indicates that all three support values are 95 or greater. Each Escovopsis node is labeled with a sample code, the name of the associated ant species, and the country of origin (AR, Argentina; CR, Costa Rica; GU; Guyana; EC, Ecuador; PA, Panama). Labels for isolates from Apterostigma colonies are in bold. # emphasizes the G4-associated Escovopsis, which are not monophyletic. ^ marks the two Apterostigma Escovopsis isolates included in a previously published analysis . Bars along the right side indicate the spore-color of the sample and the host-cultivar clade. Not all outgroups are shown for clarity.
