Bright white-white stipe and gills, and very acrid taste. Nice bright red caps. The red stain on the stipe of the larger one might be from the other caps after it was put in the bag when gathered. I can’t remember if that red stain was there when I gathered the sample, or later when it came out of the bag.

Recognized by sight: This Russula is not silvicola/cremoricolor — it has pinkish stipe. there are many other red Russula in our area, which require careful investigation. Just noted this old observation.

The red stain is not likely to be from the other caps.

The red pigment doesn’t act like a paint to bruise off other Russula. This pinkish tinge on the stem is quite sufficient to place doubt on going deep with an epithet on this Russula.

I agree that R. silvicola is a better descriptive name in this case. Unfortunately that’s not only subjective, but potentially leads to more instability. The ICBN rule that the first published name takes precedence is a good one. There certainly are exceptions made through the name conservation mechanism, but they are for more extreme cases than this. For example, recent DNA studies have shown that Endoptychum agaricoides (a secotioid species) is in the same group as Chlorophyllum molybdites nd Macrolepiota rachodes. The genus Endotychum is actually older than Chlorophyllum. However, Chlorophyllum was conserved against Endotychum.

Why not cremoricolor → silvicola?

Hee-hee, just when you thought there might be hope for the red-capped russula problem. I’ve always thought that cremoricolor suggested to me that the cap is cream colored. If one form has a red cap, why not get rid of cremoricolor and go with silvicola (which suggests it is a forest loving shroom, which it is…).

I guess I’m saying I would rather call the current cremoricolor, silvicola, than the other way around.

But it is not up to me is it…

R. cremoricolor = R. silvicola

Recent DNA studies have found that these are the same species and according to Mike Davis at SOMA Camp R. cremoricolor is the older name. I actually have photos of the two forms that were growing within 5 feet of each other and were most likely coming from the same mycelium.
