Observation 89589: Amanita sect. Amidella
When: 2011-09-08
No herbarium specimen

Notes: This was from back in my n00b days in the summer of last year so unfortunately this is the only photo I have. No herbarium specimen nor spore print.

Cap: white with shaggy white material which overhangs the margin
Gills: white
Stipe: white covered in same shaggy white material as the cap

Emerging from a cleft sac-like white volva with brown staining at the tips near the cleft.

I just can’t even find a good key to get me close on this one. Is it being hypomycetized or something?

If you take a look at the North American taxa in sect. Amidella, you’ll see that many of them have a striate cap margin. If you find this lady again, you could look for that. Spore size and shape is another clue…if you’re into microscopy. A cross section of the fruiting body also can be helpful as well as the shape of the sac (ball-like, bag-like, floppy-test-tube-like) and the shape of the base of the sac (round or pointed).

Along the Gulf Coast, I’ve personally seen Amanita volvata, Amanita peckiana, Amanita pseudovolvata, and Amanita sagittaria.

but not Amanita dolichopus, Amanita fallax (western species), Amanita whetstoneae, or another unpublished taxon known only (I think) from Mexico.

So I’d suggest that you start your search for an identity in the first group of four.

Very best,


That is wonderful

For a short introduction to the seven currently recognized sections of the genus Amanita, you might want to check out this page:


The WAO (www.amanitaceae.org) site breaks down the genus into subgenera, sections, subsections, etc., providing a list at each level.

Very best,

photo. Different mushroom in the same spot. It looks like there may be bands of scales, but still hard to tell.

As you can see though, neither mushroom has an annulus. Very perplexing.

the lower part of the stipe have bands of scales above the volva?

That is a cool critter.

Good luck! I have zero insight into the Floridian Funga.
