as the name implies should have both darker brown ochre and reddish rhizomorphs. The yellow peridium especially near the gleba is very common for R. occidentalis. But I still have questions with the host.

Claremont Chert in this area is upturned and drains very well. It breaks into smaller rock particles that then disintegrates into fine particles.

then this is an important observation. Typically found in sand dune areas near the coast or in deep volcanic soils in the Cascades. Chert is neither sandy or especially well-drained.

It was growing with Claremont Chert a local formation. It had no noticeable odor

Hope you made a collection.

R. occidentalis is not currently known with Knobcone pine, and no Rhizopogon I know of if associated with chinquapin. However, I agree tentatively that your photos do look like Rhizopogon occidentalis. Were they found in sandy soils? Was there an odor associated with them?
