Common: Oregon Black Truffle
Description: Perideum: the skin is charcoal black, warty to smooth; Gleba: the interior is solid and firm with light to dark grey with white marbling; Smell: raisin/pineapple fruity when young, pungent & earthy with age.
Habitat: Sept - Feb, between OR & BC, W of Cascades, 0-6" depth in dark fluffy soil in 15-40 year-old Douglas-fir plantations.
Edibility: Choice, but some may develop intestinal problems. Test first!
Notes: This truffle occurs in the same habitat as the Oregon White Truffle, but rarely in the same locations. It's normally found deeper that the White's and in fluffy soils instead of denser red clay soils. The aroma is unmistakable when young, and the delicate flavor is not as strong as the Whites.
