Amanita sp. for sure. Looks toxic to me. Hopefully someone more well versed in Amanita will comment.

I am not well versed in Amanita either, but I think you nailed it, pskept. An Amanita bisporigera. I do know enough to keep that off my dinner plate. It is a beautiful looking mushroom and deadly. Destroying Angel is the perfect name for it.

This is an Amanita in sect. Phalloideae. Regarding species - it is definitely not A. bisporigera.
Macro can be a bit wobbly in this section but you can usually get somewhere... depends on how interested you are. Did it have a smell (especially garlic or chlorine)?

Hi all. Thanks for the feedback!

I'm interested as far as knowing if this is a deadly mushroom that would be given the name Destroying Angel.
I took a whiff of them and I would not say they smell like chlorine or garlic. It smells very pungent. Similar to the smell of grocery store agaricus mushrooms when they are old.

All of Amanita sect. Phalloideae in North America except the basal taxa (which do not at all look like this) are deadly. These white species are referred to colloquially as destroying angels.
Regarding the species, the very apical annulus and odor description suggest Amanita elliptosperma, although these a tad on the large side and the base is slightly unusual (but not out of the normal range) for this species.
The others less likely candidates on the differential would be Amanita amerivirosa (usually with a lower annulus and well-buried bulb), Amanita suballiacea (often has a flattening or degrading annulus, slightly browning, smells like garlic but sometimes hard to elicit), and Amanita sp-S04 (smells like chlorine, stocky).

Thanks veggie! I see fungi like this quite a bit this time of year. It's always exciting. The Earth commands respect!

The new set of pictures is very nice and has some scale, this helps change and cut down the differential (but not the likely ID)!
We can see that all of these have very apical skirts that are pretty substantial and remain pretty cleanly white, and that the size is actually pretty large. Some of the rings on the earlier photos weren't so apical so seeing that the overall picture is apical helps. With all of them showing these features I still think it's a more robust collection of A. elliptosperma.
However it does help us rule out those previous species with pretty good confidence. The stuff I'd have on the differential now is mainly A. magnivelaris (stocky, has a felted, ample ring that turns yellow in age, but the ring is usually not so apical). A. hygroscopica is also part of the same complex and can be tricky but I don't see any of these with clearly pink gills or staining orange (yes there's orange-staining destroying angels) so it probably isn't that.
I'm glad these aren't more southerly since then you have to worry about more annoying species like A. pseudoverna and A. virosiformis.
