Happened upon these today, maybe the amanitas are the same species but I thought I'd ask.
Species #1

Habitat: In sandy soil with leaf litter, under an Oak.
Gills: White to pinkish white, not mature (veil intact).
Stem: white, enlarged at base, saccate vulva and rings present.
Cap: off white, glossy, with universal veil remnants.
Spore print color: no print yet
Bruising: bruising to yellow brown or yellow brown red
Location: West Florida
Species #2


Habitat: Sandy soil with leaf litter, under an oak.
Gills: white, slight pinkish maybe but less so than #1, veil intact.
Stem: white, shaggy, large bulb at base, saccate vulva.
Cap: white, glossy, no universal veil remnants.
Spore print color: no print yet
Bruising: tan-ish.
Location: West Florida.
Species #3

Habitat: Crappy lawn, dry sandy soil.
Gills: Tan to light brown when mature.
Stem: off white, twisted, solid, fibrous, very tough, large foot or swelling at base made of very dense tissue.
Cap: off white to khaki, with corrugations on sides of cap.
Spore print color: forthcoming.
Bruising: bruised a yellowish tan.

Thanks. I find a lot of white amanitas around here, different species. It would be neat to know what they all are.

I think the Amanita species are different because of the difference in the bulb and the texture of the stem.
My wild guess for number one is Amanita rubescens var. alba. It could be wrong though, we don't have those out here.
The second one could be from section Phalloideae, interesting texture on the stem and it looks like it has a more viscid cap than the first. I wasn't able to find a species that looks like that but I didn't look at every species in the section.
The third is interesting and pretty distinctive, someone probably knows what it is. Reminds me a little of Agrocybe, but I haven't seen one with that kind of texture on the cap. What shade did the print turn out?

The section on A.rubescens var. alba on mushroom expert says they do not occur south of the carolinas, and the bruising I think is a bit too light. But maybe something similiar, rubescens var alba is close.
The last mushrooms are indeed distinctive- They are tough little buggers. I had too pull hard to get them out of the dirt. I am having trouble printing them, I'll post it when I get one. The tissue of the base is almost sclerotia-like.

Good call on the Phalloideae section. I think I've found our man:Amanita bisporigera.
Note that the stipe may be "frequently floccose-fibrillose-squamose" and the veil is thin and delicate, meaning it can easily disappear even though it isn't particularly evanescent.
Look at these photos for the veil:

At first I was thinking Amanita virosa because I've seen scales on the stipe.

But with the veil non-existent, and your link, I think it is probably A. bisporigera.

Yea that looks like it. I thought the stem was too smooth to be that species but I didn't read the description.

The best starting point for learning about Florida mushrooms is to reference writings by William A. Murrill.
 The species name of your Amanita, is likely one of a handful of similar species and variations. All probably not very well-known, and poisonous to deadly-poisonous. R. Tulloss' website and papers are another excellent place to begin. If he had time to look at your Amanita photos, the first place he would think to look might be Murrill. And then tell you that more info is needed to make a ID request for Amanita mushrooms. See the Tulloss site for details on how that is best done. The others are probably Agrocybe as already mentioned. I have seen those before. 'Can not remember off the top of my head what species I might place them in. Do a spore print first of course. Still waiting on the rest of my books in the mail.

Your Agrocybe is Agrocybe retigera.

For collection #2 I would research Amanita abrupta and A. excelsa var. alba.
