Notes: Trying to make sense of the various forms fitting the general description growing in our area. These grew in well-lit, mature relic pine forest. They’re much more robust and shaggy than the specimen from the dark, humid Picea obovata planted patch.

Can you tell me if the pileus was originally entirely white? I have seen such specimens in Norway that reminded me very much of the white, rubescent species of western North America that is called Amanita novinupta. There is a link to a key to known rubescent taxa of Amanita sect. Validae at this address:
I think the link is listed near the bottom of that webpage.
I was one of the thesis advisers for a Brazilian student who did a thesis on Amanita. He had to deal with rubescent taxa that had been imported with plantation species of Pinus into Brazil. It was not easy. If you have an interest in trying to solve your issues with local variations in western Siberia, I’d be happy to provide supportive discussion, etc.
Do you have access to a microscope with an oil-immersion lens?
