…it was the entire root. I had found one previously to this, but I broke it off. The ground was softer here and I used my ginseng digger (big screwdriver) to carefully dig this one out. I’ve got this one dried and was planning to send it to you (along with some other stuff) here sooner or later.

Thanks for helping me to understand Lepidella a little better.

Do you think it’s possible that you didn’t get all of the bulb?

I can’t tell from the photographs whether the bottom of the “root” is complete or not. If I’m right in my guess at the ID, there was probably more “root” in the ground…

When you have a mass of flocculence under the cap of an Amanita as in this species, it’s almost certain that you have a mushroom belonging in Amanita section Lepidella…the only other thing I can think of N. America would be Amanita volvata in sect. Amidella…and there you have a saccate volva.
