Well when theres red and yellow in the same patch they can easily be seen in the same patch much like death caps growing right now to Amanita M, or ceazer amanita growing along side them with in inches of each other. I would really like to know how the mycorrhizae works with that

I would love to see pics of that rare example. What part of California? Do you find the “pure” yellows in Mexico?

Perhaps Rod

I think they are probably the same species. I am not sure that cap color is always taxonomically significant in Amanitas. I have seen red and yellow ones in the same patch in California.

Eastern red species

are more likely to be A. muscaria var. persicina. A species in its own right, due for reclassification.

Informative Well yeah to different speices can appear to have the same host tree this can be seen with death amanita and muscaria sharing the same host

As for red it was this red http://mushroomobserver.org/image/show_image/294856?q=1ebEc&size=full_size

I think i would agree it is a different red but its too far in my memory i just remember that it was as red as a brand new stop sign. but i think the west coast ones are red buy shiny while the east coast are red but not shiny. i only found 4 ever over the course of 6 years and it was the same year

A. muscaria in the strict sense is a european species, whose range overlaps in Alaska with the north american clade. The western solid yellow fly agaric is a completely different species than A. muscaria subsp. flavivolvata found in the same area. It is uncommon to find them growing side by side, but it does happen since their ranges overlap. The red-orange western form of A. muscaria subsp. flavivolvata does not grow in the east. The yellow-orange eastern form can get reddish rarely but never as red as its western counterpart. The current species names do not accurately reflect the true phylogenetic relationships in this complex.

Technically isn’t it the same species , but different variants ? So in that case can’t they just be considered amanita muscaria BTW how common is it that the Red and the yellow grow side by side… Also how common is red amamita found on the east coast ?
