volval warts appearing to be pure white and the color a little on the bright yellow side, this looks like crenulata to me. The smooth rounded stipe base fits very well. looks like the cap margin is beginning to show striations. On the crenulata I have found, striations are short.

enough rain to wipe out the stipe base warts have also removed most of the cap warts?

The base does look a little bit funky to be A. amerimuscaria, I have never seen such a wonderful globe at the base of amerimuscaria :-)

Also Bob brings up a good point, where are the rings and shaggy stipe? I know mushrooms can vary a lot from what is in a field guide but that is a whole bunch of variations.

Has there been lots of rain in your area Herb? I know these things can wear the rings away, but they also tend to make the stipe shaggier. I guess I might just be mistaken, after all I see the southern muscaria a lot and it has very weak rings and a smoother stipe. By the way has Amanita muscaria var. persicina received its species status? I remember Herb mentioning this a long time ago.

This is small.

The whole mushroom is smaller than an average closed cap of A. amerimuscaria. About 3" tall. Easy to compare in observation 47641. The cap color seems lighter, the stem lacked any scales or concentric ring zones. The annulus didn’t have a thickened edge and the bases seems rather globose. I’m not convinced this is A. amerimuscaria.
