Combining fossil-based and molecular calibrations with data on horizontal gene transfer events, the authors develop a time-calibrated phylogeny of Fungi. This timescale, which integrates analytic uncertainties, suggests an older age of crown Fungi (1,401–896 million years ago), as well as a minimum age for ancient interactions involving fungi and the algal ancestors of embryophytes in terrestrial ecosystems (1,253–797 Ma).
