I originally thought Aprica straight away when I saw it and commented so above - but then kind of talked myself out of it on second inspection, because I couldn't see any remnants of their distinctive universal veil on the cap.

I find it so fascinating that muscarias have such colour variations over there, where I am in Europe they are all deep, deep red. Only once have I seen a dark orange one. The light shades are lovely specimens.

Edit: actually, I take back my first statement. I think the white ring consistently around the rim is indeed what's left of a singular veil, and that points to Amanita aprica.
