smearing some spores on a slide, then put a cover slip over them, and hold them in place with a mild thin glue on the edges. Glycerine is often used to preserve spores over time. See if that is available at a local community college or college. Ask a biologist’s help! Try not to use something that could change color over time, or discolor the true color of the spores.

I found four different species under two pine trees one day! Twas my best day truffle hunting. Unfortunately the area I was in mostly had doug fir dominant forests. I know that doug fir is not a true fir and is in the family Pinus. I wish there had been more pine stands accessible to me.

Anyway, my Radiigera spores are few and far between and they’re smeared on the bottom of a wooden basket. How would you recommend I send them?

you have noted, Douglas-fir, Nine-bark and Serviceberry may be hosts. Pacific Serviceberry was one of the favorite species for the late Adrien Beyerle, although I personally have almost never found anything with that species. Red alder is unlike to host Tuber, although it certainly hosts Alpova diplophloeus, which may be an important fungus in Northern Flying squrrel diet. An odd thing about A. d.: when it is frozen and thaws, it has a strong odor of Bailey’s Irish creme! (Something I rather like.)

This is a small specimen, and may not be mature at this time. It will be interesting to see if Dr. J is able to find mature spores in it.

I suspect Douglas-fir is the likely host. And I wouldn’t be at all surprised if you found many more hypogeous in that area. Alexander H. Smith found some 200 species of Rhizopogon in Idaho. I’d also suggest looking near or under Ponderosa, Jack, White, and other pine species. These may be the most prolific Tuber hosts in upper elevation sites.

In the vicinity of the truffle find there was also doug fir, red osier dogwood, snow berry, service berry, thimble berry, mallow 9 bark, and Rocky mtn Maple.

I was hoping you’d see these truffle photos!
I know that you have been heavily involved in the NATS and know James Trappe. I contacted him for my project and he has volunteered to help me identify my summer truffle collection. I e-mailed theses photos to him in August.
After he told me that this specimen is of the genus Tuber, I have been interested in them ever since. I was just curious as to what other people might think of the pictures.
As far as I know, nobody has ever collected truffles in the Frank Church Wilderness before. I might be able to provide new information to the field. I haven’t sent my collection off yet though.

- This truffle was the only one of its kind that I found in that spot. It was in a riparian zone next to an Alder with a DBH of 23.5 cm. I few inches away from where I found the truffle I also dug up a nitrogen fixing nodule likely from that Alder.
- The humus was 4cm deep on the up hill side of the tree and was 12 cm deep on the down hill side of the tree. The truffle was found 7 cm deep.

Tuber species confirmed.

Has both venae externae and venae internae.

Would like to know what tree species were present, and how far underground was this located?
