I initially voted ‘could be’. I think the points you bring up about the orange coloring are good ones. A. variicolor can also appear to lack the orange tones and be grey-black (Mycowalts image) I think this is an interesting observation. Amanita rachopus group seems likely. Thanks for the dialogue!

I noticed after I posted my comment that you had destroyed your name proposal. If you no longer think this is A. variicolor do you still think A. rhacopus unlikely?

A. rhacopus has or may have a 2 toned cap as well but none of the yellow to orange colors of A. variicolor. The description and photos at http://www.mycoquebec.org/... rhacopus Y. Lamoureux nom. prov. / Amanite à pied déguenillé&tag=Amanita rhacopus&gro=13 fit this obs well I think: “The amanita is characterized by its brown-gray hat, bare or decorated with gray flakes, to furrowed margin, its not ringed foot, mottled, based adorned with a gray strip is its shoot in various hardwoods.”
