Observation 10012: Tuber oregonense Trappe, Bonito & P. Rawl.

One of the successes I’ve had cultivating mushrooms at Paul Bishop’s Tree Farm was also the second and perhaps the most controversial. Some people claim that since Tuber oregonense had already been found here, that cultivation had not taken place, merely enhancement. Possible, but I think improbable. Production went from 5 pounds collected from a single 200-foot row of Douglas fir in 1986 to what I estimated as 300-1300 pounds per acre per year. That extreme variation was caused by several different species of truffles fruiting at different times of the year with the same trees. Each species was producing between 150 and 650 pounds per acre per year, and increase of 10 to 23 times what baseline data suggested. Here are some photos taken at Paul’s of Tuber oregonense, mostly in situ. When people ask what I look for when truffle hunting, these are what I show them. As Dr. James Trappe has stated, animals are far better at locating mature truffles than people are. And where there is one truffle partially eaten, there are likely more in the immediate vicinity.
