Oregon has four native truffle species that are recognized for their culinary value and harvested in the wild. They include the Oregon Winter White Truffle (Tuber oregonense), the Oregon Spring White Truffle (Tuber gibbosum), the Oregon Black Truffle (Leucangium carthusianum), and the Oregon Brown Truffle (Kalapuya brunnea). The French Black, or Perigord truffle (Tuber melanosporum) has also been successfully cultivated and harvested by New World Truffieres in Oregon and numerous other spots in North America through planting orchards of inoculated host trees.
