I found this updated version of the synoptic keys published by Kibby and Fatto here.http://www.mtsn.tn.it/russulales-news/id_kibby_fatto.asp

West coast russulas here. http://www.svims.ca/council/Russul.htm

Is it the same situation with the west coast R. cremoricolor?
Is there one species of bitter red Russula that is more common on the east coast than the others? Thanks!

here are some species of

acrid or bitter tasting reddish russulas in eastern NA from Kibby & Fatto’s key.
the colors I have listed are the primary colors mentioned in the descriptions.
R. bicolor (copper-red to pale yellow-ocher)
R. flavisiccans (red to pinkish)
R. subpunctata (scarlet to dull-red, rosy-red)
R. beardslei (peach-red)
R. pungens (peach-red to opal-red to mod. reddish-orange to strong-red)
R. macropoda (strong-red to scarlet)
R. maculata (coral to pale pink)
R. astringens (blood-red)
R. aquosa (pale cherry-red)
R. montana (deep grayish-red. except the ones that Ray ID for me were bright red)
R. vinacea (purplish-red)
R. humidicola (salmon to reddish-salmon or brick-red)
R. rugulosa (yellowish-red to deep red)
R. applalchiensis (dark red)
R. corinthiirubra (deep red)
R. veternosa (moderate red to reddish-orange to deep pinkish-orange)
R. fragiloides (bright red)
_R. nigrodisca) (dull red margin, dark disk)
R. borealis (strong-red, blood-red)
R. operta (blood-red)
R. tenuiceps (deep rose-red, blood-red, crimson)

and last but not least…
R. silvicola (pinkish-red to pale scarlet)
and R. emetica (bright scarlet to cherry or blood-red, sometimes whitish when washed out)
emetica has been the field guide name for any acrid red russula for years. It does occur in North America but probably doesn’t make it any further south then far northern Maine.

This list doesn’t have any of the acrid red-capped ones with a colored stipe or any of the mild tasting red-capped ones which may out number the acrid ones. It also doesn’t have have any of the undescribed taxa, who knows how many that may be.

Thats true

We dont know the reason jason chose the name R. emetica.
If its on the east coast, red and bitter, growing in a habitat besides sphagnum, its probably R. silvicola. The name R. emetica has been misapplied to North American material, conspecificity has yet to be shown between the western R. cremoricolor and east coast material described as R. silvicola.

There are

LOTS of species red russula… putting names on them without spore color/ornamentation/size, etc. Taste, discoloration, tree associates, chemical reactions, (on and on and on) is crazy
