Patagonian tree fungus is the secret ingredient in beer

The new issue of PNAS shows some evidence for the origins of my other favorite beverage.  “The draft genome sequence of S. eubayanus [Patagonian tree fungus] revealed that this long-sought partner of ale-yeast gave rise to a domesticated, hybrid species used to brew lager beer.”

It’s worth a quick look at the picture on the cover. Who would guess something so ugly could yield such a tasty product. Beer is, in the apocryphal words of Ben Franklin, “proof that God loves us and wants us to be happy.”
