Recognized by sight: Rhizopogon occidentalis has been reported from Lodgepole pine and Ponderosa pine only as far as I know. Knobcone pine supports other Rhizopogons, but not R. occidentalis that I know of. This would have been an important collection had it been collected: I know of no other Knobcone pine Rhizopogon collections anywhere.

It is growing with Knobcone Pine & Manzanita. aprox 900 ft Elevation. aprox 30 miles from ocean, Growing in East Bay Hills. I usually am with someone else who has ID these. I brought a simular one to the MSSF fair this Sunday and it was ID as occidentalis. Usually you have to check Squirrel holes. but these were sitting visible near the surface. i did not collect it. Thanks for the questions.

How did you arrive at R. occidentalis?

Yes, I see the sandy soil. Proximity to Pacific Ocean? Nearby tree species? The reason I ask is that this does not have the yellowish-orange fibrous exterior I associate with R. occidentalis, nor does it have the yellowish to yellow-brown gleba. I suspect this may be a different species, perhaps R. subochraceus or R. ochraceorubescens, but without a voucher collection it’s going to be difficult to prove.
