Pigmentation highly variable in amerimuscaria

Dr. Tulloss has recently convinced me of this. They come in lots of different colors due to varying degrees of two pigments, a purple one and a yellow one. His explanation is here.

The concentric rings at the base of the stipes on your specimens indicate muscaria; flavoconia are smooth at the bottom.

As for the name “Amanita muscaria var. guessowii Veselý”. Even though this name accurately picks out the yellow orange American fly agarics, it fails taxonomic muster, because the name means that American and European fly agarics are two varieties of the same species, which is not the case, they are two different species. Micro and molecular comparisons point to an evolutionary divergence between the European and American fly agarics.

Ret’s explanation and my analysis can be found here:

Likely A. flavoconia

A. amerimuscaria with that tint of yellow on the stipe?, i dont think thats an option.
