I didn’t look at this area closely enough to map the closest Douglas-fir. There could have been something (even bigger than a seedling) within 300 feet which I did not see or did not notice.

I changed the OMS vote to “promising”, so the community vote is now Rhizopogon vinicolor.

don’t grow in scat. The remnants of Rhizopogons are found in scat. Rhizopogons are food for many animals.

The Douglas–fir would not have to be near-by. Animals often transport sporocarps of hypogeous fungi. But Douglas-fir within 300 feet? Nor do the Douglas-fir have to be large. Rhizopogons are often found with seedling trees in nurseries. It may be harder to recognize seedling Douglas-fir which are barely 6 inches tall.

Dan:

The habitat where I found these is a Pine habitat. I don’t remember Douglas-fir.

The Rhizopogon were sitting on the surface adjacent to a small pile of scat. Perhaps they were transported there inside some animal. (So perhaps they did grow up near Douglas-fir.) Maybe their color comes from the scat.

of Rhizopogon vinicolor. Must presume there was some Douglas-fir nearby. “…by maturity dark cinnamon brown…”—NATS Field Guide To Selected North American Truffles and Truffle-like Fungi, by Matt Trappe, Frank Evans and James Trappe.

Believed to be species specific (found only with) Douglas-fir.
