Notes: under Oak Tree with Pines nearby about 20 feet from the lake on the north side.
Here are notes from the day I saw it. However, the note about the lack of volva is not reliable. I’m not sure I would have recognized it then, I was completely new at looking at mushrooms.
__The stem was not hollow. I saw no vulva sac. The mushroom was very soft and flexible. I tore open the stalk and there was no latex or watery liquid, however, it did have a very weird fishy odor, bad odor.
The gills were a creamy white almost slightly pink.__

It appears that Ben is well into his study of things other than Amanita. The last time we talked, he was studying the human-guided evolution of the organisms that live on the surfaces of cheeses and that have been carefully protected (sometimes for thousands of years) by humans who have a culinary and financial interest in preserving the tastes and other qualities of traditional cheeses.
I’ll look for an address for him.
Thanks for information and links.
I will keep a look out for them next year and contact the researcher to see if they still want samples if I find them.
This species has not been posted on MO very often. From what I can see, you DIDN’T see a membranous volval sac on A. theirsii…because it doesn’t have one (and its absent in your photos). The volva of A. thiersii is very typical (and is used to define) Amanita subsection Vittadiniae, which got some press lately because many of the species in the subsection apparently do not form mycorrhizal relationships with trees. They just delight in the human idea of “lawns” and chow down on grass clippings. They were one of the first amanitas to be grown in a petri dish (by Ben Wolfe in his PhD research) and all they had to feed them was pure cellulose (or alternatively, sterilized grass clippings).
There’s more about A. thiersii and Ben’s research here:
