and is not flavorubens can sometimes have a yellow universal veil. The same species sometimes retains powdery yellow volval remnants on the underside of the universal veil. For example:


Very best,


So far toxins seem to be associated with evolutionarily related groups…

not just single species.

Amanita section Phalloideae has many species including amatoxins and phallotoxins.

Amanita section Validae has many species including toxins that make your red blood cells break, leading to gastrointestinal problems that usually successfully expel the junk you shouldn’t have eaten.

Amanita section Lepidella includes species having one or more toxic amino acid.

It seems that any of the older names are under revision as unlikely in the Americas.

All that fun with the Siberians using A. muscaria for food / entertainment / medicinal purposes may have nothing to do with our mushrooms.

However, A. rubescens is not a North American taxon. Essentially, if a name of an Amanita was originated in Europe it is highly likely to be mis-used if it’s used in the eastern U.S. There are exceptions, including A. porphyria.
