Unfortunately, I didn’t do the measurement on the fresh material. I dried the amanita whole, so current measurements are: cap = 4 cm in diameter; volva = 4.5 cm long (measured with the longest limb).
Originally the specimen was light cream or off-white in color with darker patches on the cap and a few splashes of pink. I didn’t see a lot of flocculence on the upper stipe, but there was a nascent fluffy “ring zone” typical of some Amidellas. It was a button, and I succeeded in expanding the cap overnight, but it didn’t drop spores.
Let me know if you want some of this material. I saved it in mind for you and the NJMA herbarium.

Can you give us an idea of the size of the cap and the length of the volval sac?

A. whetstoneae doesn’t usually stain so strongly.

Very best,
