Who: Ron Pastorino (Ronpast)

Specimen available

These were curious as they were growing near some kind of firs which were surrounded by Bishop pines. Normally, these grow under oaks in the Bay Area. No Oaks in sight in this area of the coast.
Also, the spores were a little wide, ~ 12.8-14.8(16.0) X 5.9-6.5 microns.(Thiers = (10)12-14(16) X 4-5(6).

The taste of a substantial piece of dried material was moderately bitter

and persisted for some tome.
Didn’t expect to see B. coniferarum that far south but they certainly could be although there wasn’t any obvious reticulation on the stipe and there was some red tints on the lower part. B. rubripes is also a possibility I think, but the spores are again a little too wide.

They’re not my idea of the right color or stature for our butter boletes, and along with the habitat and larger spores, I’ll suggest Boletus coniferarum
