COGNAC, France --
Truffles, one of the most lucrative, prized, secretive yet legal crops in the world, are in trouble. Just what is responsible for this travesty may be impossible to prove, but the experts' list of usual suspects often begins with climate change.
The lumpy, earth-colored fungi prized by chefs and gourmets around the world can fetch $2,000 per pound on the open market. A pound of the rare white truffle (Tuber magnatum) found in the wild in Italy, Slovenia, Croatia, Serbia, Hungary and Romania can fetch $6,000.
