Figure 2

Chronogram of eukaryotes emphasizing Agaricomycetes and potential ectomycorrhizal host plants from topologically unconstrained relaxed clock analysis. Posterior probabilities of nodes were 1.0 except where indicated otherwise. Node bars are 95% highest posterior density intervals of node heights, expressed in average number of substitutions per site. Black node bars correspond to groups in Figure 5 and Table 1.
