A. Mairei is Brown? I hope so.

I agree with Ret. My reference is Wild Mushroom of Tokyo (www site). The pictures of A. Mairei are brown-capped, with some veil remnants as well.

Could this be A. argentea or something whiter than A. argentea?

In much European literature, Amanita argentea is said to be a synonym of A. mairei. I have studied the types of both species, and I don’t agree with the view that the two names refer to the same species. The watercolors of mairei by both Foley and Maire (all at Montpelier) show a brown-capped species. I have placed a photograph of one or more of these watercolors (I can’t remember off the top of my head) on the A. mairei page of the Amanita Studies site. Amanita argentea differs macro- and microscopically from A. mairei. There are other possibilities (of course) for whitish species of sect. Vaginatae in Europe. I don’t think I could tell them apart by photograph without some clues as to habitat, spore size/shape, etc.
