My impression from the diapositives (slides) is…

that this species is grayish and, in that way, conforms to what little information we have about A. battarrae.

This is what I call Amanita battarae: two-coloured cap, rusty volva and growth on acid soil. Usually the gill margin is blackish. The similar A. submembranacea has a more uniformely coloured cap and a white but greying volva. Both grow in conifer forests, but A. battarae can also grow in acid decidous forests. And there is a third species, uniformely coloured but lighter then A. submembranacea, with white volva, growing in decidous forests on neutral to basic soil. This is what I would like to call Amanita umbinolutea. I have only dia of this one, no digital.
