I don’t often see any large Lepidellas in my geographic aree (NE PA). This one was found in SW PA. Shapes of warts on cap, and semi membraneous veil which is striate above match ret’s descriptions.

Large, difficult to dry, and bad smelling mushrooms do not travel well while on a vacation :-) I did find atkinsoniana once before, up here in the NE. You IDed it for me, Rod. I’ll look at my photos of that one.

The one seen here was about 8 or 9 inches tall.

I have another suggestion…

Good photos! As is usual, Dave.

I think the warts are grayish, which is unlike daucipes. I have a feeling the warts will turn brown in a day or so. The rounded bottom of the bulb (daucipes means “carrot foot”) and the many, many rows of warts suggest to me Amanita atkinsoniana. Like I said, if the warts turn brown, then I’d definitely go for atkinsoniana in this case. Also, the annulus should either fall off or turn yellowish and slimy if this is atkinsoniana.

When we get the more unusual lepidellas, I always think about a certain Mrs. Williams who wrote in the Asa Gray Journal in the late 1890s that she was always frustrated by having to relearn the large white amanitas (i.e., the lepidellas) every summer.

Very best,
