Fig. 2

Divergence age estimates of major lineages of Hirsutella (asexual morphs). Chronogram was constructed based on the tree (Fig. 1) from maximum likelihood analyses. Geological times are provided below the chronogram and the dark gray rectangular box highlights the Cretaceous. Calibration (crown node of genus Ophiocordyceps) was based on P. coccophagus, a fungal parasite of a scale insect from the Early Cretaceous (Upper Albian) (99–105 Mya), marked with an asterisk “*”. Error bars are shown and each represents the 95% highest posterior density (HPD) for a node age. The red line “a” represents the mass extinction event of the Cretaceous–Tertiary (65.5 Mya)
