Collection location: Clackamas Co., Oregon, USA [Click for map]

Who: Daniel B. Wheeler (Tuberale)

No specimen available

Collected near Timothy Lake, Clackamas Co., OR. Perhaps the largest specimen of Hydnotrya I have ever seen. Were it not for the mushrump it pushed up, I may not have seen it. Suggested to be Hydnotrya colossa by Adrien Beyerle. Found near Western hemlock.

Hydnotrya species as yet undetermined

There is no doubt that this specimen is a Hydnotrya species. To date there is not a H. colossa species name. As usual putting generic names on truffles is usually much easier than getting a species name. A species name msot often is the result of microscopic study of the spores and micro-features of sterile tissues. When in doubt send it to me for species identity.

Send me an email for the protocol for sending specimens in for ID.

Using the quarter as reference, this Hydnotrya is over 6 inches across!
