Figure 6.

Phylograms of eukaryotes emphasizing Agaricomycetes and potential ectomycorrhizal host plants from non-clock maximum likelihood analyses implemented in RAxML. The large tree is the optimal topology obtained from a topologically unconstrained maximum likelihood (ML) analysis. Numbers along branches are frequencies from 100 bootstrap replicates. The small inset tree is the gymnosperm clade from a topologically constrained ML analysis (the entire dataset was analyzed, but only the gymnosperm clade is shown). Both trees are drawn to the same scale. Symbols as in Figures 2 to 4.
