White Amanita specimen. Growing under White oaks,Tulip poplars and Sassafras trees with patchey areas of moss, heavy leaf litter. I observed this single mushroom growning about 10 feet from two more of the same species. The stipe had a distinct aroma of raw potato’s while the gills had a smell somewhat of sulfer.

The two main (as far as I know) non-reacting taxa that are of significant size are elliptosperma with a thin, white, membranous skirt-like ring and magnivelaris (perhaps with a more northern distribution than WV?) with a cream-colored, rather thick, felted-submembranous, skirt-like ring. In the pix of these two taxa on the Amanita Studies site, notice how the limb of the volva tends to stand up rather firmly on the stem’s bulb…and at a distance from the stem. r.
I got this information from W C Roody Mushrooms of West Virginia and the Centeral Appalachians page 63. That is good to know I carry a small bottle of KOH with me in the field so i check a lot of fungi. I have had some that had no reaction to KOH and looked similar to A. bisporigera
The original description of A. verna as not reacting to KOH actually refers to the white variant of A. phalloides. All European specimens identified as A. verna and recently tested with KOH have shown a strong yellow-orange reaction (depicted on the verna page of the Amanita Studies website). The European virosa and the Asian subjunquillea var. alba also turn yellow with KOH as does the western N. American A. ocreata. In the eastern U.S. we do have at least two white destroying angels that DO NOT turn yellow with KOH — A. elliptosperma and A. magnivelaris.
Liquid Drano has potassium Hydroxide in it also you should get some Iron salts I think the local pharmacy may be able to hook you up there and some Iodine all these chemicals have reactions to fungi.
Hey i have something that you can really have fun at try using KOH Potassium Hydroxide on some of the mushrooms you find. A lot of them will give you a color reaction. This is a good way to Id some of them especally a bolets and a lot of agaricus,polypores and Amanitas. A Bisporigera will stain a brillant yellow on all parts,cap stip. and base in KOH. There is another closley related spcecies of A. bisporigera called A. verna and it dos’nt stain yellow in KOH. Ok Kate im going to turn you into a mushroom nerd and then when that happens there will be no way out. take care Eddee
