Notes: This is the Oregon Black truffle, Leucangium carthusiana. It used to be known as Picoa, but Dr. James Trappe had to change the name once he realized that Oregon also had true Picoa, which do not have warts on the peridium. Leucangium carthusiana has small purple/black warts on the peridium. It is associated solely with Douglas fir that is currently known. This is the best eating native truffle I am aware of, having aromatic elements of coconut, chocolate, pineapple, hemlock needles, and a host of other ephemeral odors/tastes. It is always complex, is best in my opinion when it smells like a Mounds bar, and just thinking about it makes my mouth water. This specimen was purchased at a local mushroom wholesaler, but as the gleba shows, is very mature. Unlike some truffles, this truffle can be dried and later reconstituted with only minor loss of quality.
