The finding matches with climactic modeling suggesting that Ireland would be a hospitable environment for the yeast, said Chris Hittinger, a professor of genetics at University of Wisconsin — Madison, who was on the team that found the yeast in Patagonia and not involved in the current study. What’s less clear is why the yeast been so difficult to find in the wild beyond South America, where it grows plentifully in association with beech trees and is thought to be a native species.
