The Dr. Davis lab has been sequencing the California russulas and here is a link to his page on this species. He calls it Russula cremoricolor.

I tried an alignment of sequences (ITS1/5.8S/ITS2/28S) between Russula emetica (grows mainly with pine in Sweden) and Russula cremoricolor (British Columbia) and found them identical(!) Only one bit differed, and that was an erroneous “Y” instead of a “T” in one of the sequences..). My conclusion is that you can count on emetica in North America.

My understanding is the Russula silvicola is a broadleaf tree associate. Is there something recent regarding Russula emetica mot being in North America?
The Quebec website still lists it and it is usually pretty up to date.
