Fig. 9. Phylogeny of fungal cultivars and free-living fungi based on Bayesian analysis of the ITS 'fungal barcoding' region conducted in MrBayes (Ronquist et al. 2012). Ant-cultivated fungi are divided into two clades, Clade 2 (red branches) and Clade 1 (blue branches); free-living fungi are represented by black branches. The cultivar of Paramycetophylax bruchi is represented with a blue font and a red star. Nodes with posterior probability of 1 are represented by a blue circle, whereas nodes with posterior probabilities between 0.90 and 0.99 are represented by an orange circle. Nodes without circles indicate posterior probabilities lower than 0.90. Green box indicates the clade of fungi cultivated by the yeast-growing ants in the genus Cyphomyrmex and the blue box indicates the clade of fungi cultivated by the leaf-cutting ants and Apterostigma megacephala.
