The solid yellow PNW variant is best represented by the species Amanita muscaria var. formosa as described by Thiers.

why the vote against A. muscaria var. muscaria?

The safest thing to say…

is that the distribution you state is about as much as is known at present. Collecting material in northern Canada (in habitats similar to the montane areas in which collectors found the European muscaria in Alaska) might produce some new data that changes the picture. The hypothesis of Geml et al. is that the last entry of muscaria into North America has not expanded very far because the a previously arriving ancestor evolved into subspecies flavivolvata, which is pretty good at holding onto its turf in the New World.

that makes Alaska and the PNW the only parts of NA to host A. muscaria var. muscaria, correct?

In the Geml et al. study of the muscarioid taxa…

it was found that the yellow specimens from the PNW were yellow color variants of the true A. muscaria var. muscaria.
