Truffle hunting in Oregon
Beyond the techniques for foraging afield, scientists are getting involved in the hunt from their labs.
"It's an exciting thing to participate in," said Dan Luoma, a world market on this food delicacy."
Luoma is an Oregon State University professor of forest micology. He performed a DNA test on the truffle Ilsa found "to verify at the molecular level that it is indeed the right species of truffle," Luoma said.
