When: 2011-06-27
Herbarium specimen reported

Edit:
Nearby trees (closest to furthest)- Fagus grandifolia, Quercus coccinea, and a species of Acer

Pileus:
5.5cm, dark yellow in center, fading to pale or creamy yellow half-way to margin,
marginally striate (1.6-2cm)

Lamellae:

Well, I still don’t feel very much persuaded to change my inclination toward thinking this specimen is A. banningiana. I’d say that the things most likely to be confused with A. banningiana are _A. arkansana and a “code-numbered” species on the WAO site as “Amanita sp-N12”…

Sporographs (with the available data) don’t do too good a job separating the first and last of these, but you can see differences in cap shape, cap color, stipe and annulus color…and…DNA sequencing segregated the three taxa as well.

I’m terrible with colors

I’m terrible at describing the colors of mushrooms. I was going to call it orange but I decided dark yellow. I don’t know why… I guess I looked at the area just before where the colors were starting to fade to a lighter yellow and called it dark yellow… There was orange in the center of the cap becoming light yellow as you go towards the margin.

…is a characteristic of A. banningiana.

Matt, what did you mean by “dark yellow” in the center of the cap. It seems like the flash may not have brought out the color in the middle of the cap too well. Maybe that is what is raising questions about this ID?

What is it that makes you think this isn’t A. banningiana?

The first photo shows a long-striate cap margin. This doesn’t belong in the Phalloideae. Since the stipe is not fully expanded, I suspect that the volva will “look smaller” on a fully expanded specimen.

An awful lot of yellow

makes A. phalloides unlikely
