sensu auct amer?

Both Mushrooms Demystified and the Kibby/Fatto key (russulales news) support R. fragilis. I’m a little confused as to the best name to apply (sensu auct. amer or not?). Obviously this was found in “america” but does that mean there’s no way it could be the original European species? I don’t know how they’re different or where they occur so for now I’ll leave both names.

Russula puellaris is close but not acrid. Thanks anyway for an initial ID idea :)
