Abstract: Hundreds of yeast-like fungal cells were found in a fragment of Dominican amber dating back to 15–45 million years ago. While yeast-like fungi are common and important in many extant ecosystems, fossils of these morphs have not been reported previously. All evidence indicates that the fossilised fungi lived in a moist tropical forest and utilised a fluid substrate, possibly plant exudate.
