Truffles that grow in the PNW
The 3 main culinary truffles are:
Oregon white truffle (tuber gibbosum; tuber oregonense)
Oregon black truffle (Leucangium carthusianum)
Oregon Brown Truffle (Leucangium Brunneum)
There are many non-culinary truffles. One of the best resources for that information is the field guide to North American Truffles which can be purchased at the following site. https://www.natruffling.org/tfgbuy.htm
