I do not think it is sylvestris.

There are aspen leaves there too.
So many possibilities even in poor Europe.
I learned not to ID a Russula without scope and special literature (best with a little help from an expert) and macrochemic color reactions.
I think there are so many still undescribed species in Northern America. Who knows? Is there some capacity for them?
The exact same color can have R. betularum with birch, no idea if this is growing in your area, R. gracillima, other variants or species in the group of emetica, and many many more. I still haven’t found more than a quarter of all the Russula of Europe and I’ve been in the South, in the North, in the West and in the Middle of the continent. This is a very tricky genus.

I learned a lot from your comments on Mushroom Obs.

I was told that the most widespread variation of R.emetica is R.Silvestris
Cap often fade to pink and ivory white, some are completely white.
Grows with Quercus and Pine, usually between mosses.

“My was growing in moss, under pine in groups (and close by there is a couple of young Oak) red and white mixed together.Very hot..brittle gills and hollow-stem.

I do not know who has searched all parts of North America in order to know exactly what is growing or not.

Russula sylvestris is mycorrhizal with pines. But there are a lot of lookalikes. Do you even know if it had an acrid taste?
Furthermore I never heard of R. sylvestris to grow in North America.

you’re right

Thank’s Walter for your help

naming a Russula which is European is uncertain at best.

is there a reason why you changed my obs. ??

after consultation with mycologists from Europe
and reading a few books that contain a description and pictures R.Silvicola
I think that the name is wrigt. R. emetica var. silvestris
