It does look similar, no problem with that.

Thanks for the link to the key!
Knowing how important the choice of hosts is for this genus, it’s interesting to see a Russula key with almost total lack of such information.

It is listed in Thiers’ Russula of CA, p 69 (1997), and says rather common, widespread, and well-known. There is also the listing in Mykoweb:


And it gets mentioned in Mike Davis’ key to Russula of CA:


Although in all of these it seems to only say found in mixed forests, not if they are found under hardwoods or conifers. I don’t see any notes from Davis if the sequences were close or not there. I think he has most Russula of Salt Point sequenced by now, and he might only use names if they are a decent match.

Daring? Interesting…

Well, that is interesting, if this is a daring id. This is a rather normal down the middle id for around here. People have been consistenly calling this R. olivacea around here for years. Certainly mild taste (I ate half of the ones I found here). There was tan oak near by here, but I think people usually find them around pine trees on the coast. This was Salt Point here, so I would think that Mike Davis has sequenced them by now, I wonder what that says?

mild taste, yellow spores? Grows with deciduous trees in Europe..
