Observation 10058: Tuber oregonense Trappe, Bonito & P. Rawl.

Animal mycophagy is the dispersal of spores through the ingestion of a fungus by an animal. The spores pass through the animal without harm, and are excreted in the feces some distance away. A California Red-backed vole must eat its weight in truffles each day to stay alive. Often a complete truffle is too large for it to eat at one time, so it may leave it for another meal another time. Chris Maser has stated that a California Red-backed vole produces some 300 fecal pellets a day. Each of those pellets contains over 10,000 truffle spores, since the vole rarely eats anything other than truffles. These are photos of Tuber oregonese as originally seen in a Douglas fir plantation belonging to Sandy Streit, located near View, Clark Co., WA. The pits have not been disturbed. The truffle rake is shown for scale only.
