One other point is that Thiers’ application of the name muscaria var. formosa was to a yellow color variant of the Eurasian A. muscaria that only exists in the northwest of the U.S. and southwestern Canada. It is genetically the same species as the red muscaria of Europe and Asia. The yellow northeastern “muscarioid” is the same species as the red-capped muscarioid of the Americas.

Very best,

Rod

for the eastern NA yellow muscaria type is Amanita muscaria var. guessowii. But I suspect this one may be an example of A. flavorubens. I base my suggestion upon: yellow warts on cap, lack of basal bulb/structure associated with muscaria types. But, I don’t see any of the brwon staining associated with A. flavorubens. The one area where this brwon staining is often first seen in in the context inside the stipe base.
