1.8cm diam sphere with pointed base. Buried in needle duff under 5-needle pine. Surface is reddish-brown ad granular, and less than 1mm thick. The outer layer easily peels off. Inside that is a 1-2mm thick light red layer. This layer is cartilaginous. The interior is white, soft with some radial-fibrous structure.
Does Rhizopogon have these two peridium layers, one thin and the other thicker?
This truffle was found partially dug up in a forest dominated by Douglas-fir and ponderosa pine

I'm a squirrel mycophagy researcher. And we found this on a log cached by a squirrel.
