Which type?

I don’t see A. muscaria of any type with any regularity. I just checked all the photos I have of the Amanitas I found in this area in 2010. In contrast to my memory, well over half have the more robust (drumstick shape) I associate with var. guessowii. Maybe they really are all var. guessowii.

The weather can contribute largely to these morphological variations.

While it’s entirely possible that there is another distinct muscaroid taxon that is indigenous to the east, without more specimens to compare it to, and microscopic characteristics to gauge it by, it’s completely stretching it to make that assumption.

I have personally noticed wildly different phenotypes in regards to the eastern taxon A. muscaria var. guessowii.

This one looks like it dried out and stopped growing.

What is the type A. muscaria…, that you are referring to?

A. muscaria subsp. muscaria does not occur in the east unless it is a transplant. This certainly isn’t that.

why var. guessowii? I have definitely seen that variety:

This is much less robust, has a thin, flat cap, minimal volval remnants hanging from the margin, and a characteristic stipe base. The photo is typical of several of specimens from the same site in 2010 (which could be posted). 2011 did not produce much of anything. I have not done microscopy, but I was hoping that this observation (and site) was a good example of the ‘type’ A. muscaria…, I know there are issues; certainly this could be A. muscaria var. guessowii.
