Notes: These were fragile. I see them often but usually only one and over-mature. This time I found 5 in an area about 10 feet diameter. One was over-mature but the remaining were fresh.
Growing in a mixed hardwood and pine area with much underbrush.
Cap – max 4.5 cm. Striations ~ 16 mm, pleated at striations. Grayish, grayer at center.
Gills – white – free. Medium spacing, some short gills.
Stipe – 4-4.5 inch long. Has fine granules on surface. No ring seen, nor remnants on the stipe or in the dirt.
Volva – ~ 3/4 inch long
Spores – spore print white
Spore Measurements – in progress

I sent a list of questions to Dr. Benjamin and have already received an extensive reply. The BRIT capabilities seem impressive to me. I don’t believe in passing along emails but I am sure he would be more than happy to send you similar information about BRIT’s holdings and capabilities.

Botanical specimens are much more “tough” than mushrooms. The latter are very liable to be attacked by molds and destroyed. This is why it is especially valuable to have a mycologist on the staff where you deposit fungal specimens. The nonmycorrhizal amanitas absorb water from the air with great ease and can become almost spongy. They are especially the target of molds.
Thank you for generously agreeing to send the present material.
I’d be glad to send you some. I have the 3 complete ones. I can send all to you. I’m starting to send specimens to the BRIT Herbarium in Fort Worth, but I’m sure I can get more to send there.
The rather narrow spores, as I’m sure you know, are not very common among species in section Vaginatae in more northern parts of North America. If the spores were presented to me alone, my first guess would be that your specimens would have rings on the stem and belong in the Caesareae. But I don’t see any rings, and the volval sacs are longer and more well-formed than I am used to seeing in species like A. pachysperma.
I’m very glad to know you managed to collect some in good condition.
Would you be willing to share some of your collection for us to study?
