This material has been received and accessioned to Rod’s herbarium. We have scheduled it for DNA sequencing.

I agree with Danny.

Hello, Ron and Stephen. I checked into Stephen’s collection. You may have a point. I see that I came up with the same Murrillian name in both cases (for lack of anything better). I will see if we can extract DNA from both the collections. Then we have another point of comparison.

Very best,

Rod

Rod, even though the spore numbers don’t quite match,

Stephen Russell pointed out that he had found a similar Amanita in Indiana a few years ago http://mushroomobserver.org/107842 , which I believe was sent to you. They do look very close.

Murrill never mentions the color of the volva; but A. neoneglecta is described…

as having a white cap. Jenkins reported it as belonging in sect. Validae (under the original name—“A. neglecta”). What doesn’t work is that its spores were reported as narrower than spores in Ron’s description.

Still looking.

Well, my socks are officially knocked off.

I have never seen this; however, I think I have read a description…I think a Murrill species originally described from Florida.

I’ll try to track it down.
