It was an older mushroom…

and the flesh was full of worms so that may have limited the staining. I do remember brown around the bug tunnels if that’s any indication. I don’t remember any staining of the other shrimp Russulas I have found. I suppose one needs to be looking for it. Interesting the gray-green color with FeSO4 on the flesh as noted on mycoquebec.org I will try to remember to look for that next time.

The xerampelina types…

generally bruise brown on the gills and/or the stipe.

I just did little checking on the name clavipes. My understanding has been that what Phillips had called xerampelina var. elaeodes in “Mushrooms of NA” was eventually called clavipes. Index Fungorum lists two different currently accepted synonyms for elaeodes… clavipes and pseudo-olivascens. However, judging form the authors’ names and other information available on IF, it looks like each of these names is European. Champignons du Quebec includes a description of R. elaeodes.
So there appears to be a fair amount of confusion about the greenish Shrimp Russula of (eastern) NA. But by any name, the brown(ish) staining is a strongly associated trait.

I didn’t see any blackening or reddening of any kind.
