these truffles smell like a cross between pineapple and mango with a hint of chocolate. They are sweet smelling and not garlicy like the T oregonense and T gibbosum. They are better paired with desserts in my opinion.

quite likely, and very probable. A positive identification requires seeing a section of the interior: mature L. carthusianum should have tiny black spores visible in a white-veined matrix. The darker the overal gleba, the more mature the specimen is likely to be. Also helpful would be any noticeable odors associated with this species. My favorite stage is a combination of chocolate, coconut and pineapple/pear. The odor is often difficult to describe, but quite distinctive, and may only last for an hour before changing again. The warts on the peridium make this almost positive by itself: very few hypogeous fungi in Oregon known with warts. However, L. brunneum also has brown warts and a relatively thick peridium compared to L. carthusianum.

According to Lewis A. McArthur’s “Oregon Geographical Names”, p. 574, “Pedee, Polk County. Pedee owes its name to Colonel Cornelius Gilliam who was born in North Carolina in 1798 and came to Oregon in 1844. See under Gilliam County. He was killed in 1848. Either he, or members of his family, named Pedee Creek, a tributary to Luckiamute River. Pedee community is near the mouth of this creek. The name is, of course, from the famous river of North and South Carolina which was doubtless frequently in the minds of the Gilliams. The stream in the South is officially Peedee, but the place in Oregon is spelled Pedee.”
