Thanks, Doug. Your explanation was helpful.

Just going by Thiers’ monograph

This isn’t going to make sense unless you have Thiers’ monograph on Russula in CA. But he describes a species of Russula from the Stanford area, that has similar colors to R. silvicola when young, and also with white spores and acrid taste.

But in R. silvicola when it ages it can dev. yellow spots in the cap, but mostly stays red. R. paxilloides when it ages the red fades away completely, giving in age a cap that is mostly white, but with some red patches. The photo of the older cap, is mostly white with a reddish patch in the disc.

Also looking at the spores, R. silvicola has large warts, with a partial reticulum, and R. paxilloides has smaller warts with a full reticulum. Which is what I saw.

But I need to at some point get back to details in the cuticle, but I think the difference in the monograph were pretty small, and the red fading to white was the main difference.

It looks like cremoricolor to my inexperienced eyes—please tell how you identified this.
