The fact that the cap center is orange-red and not brown or yellow…

raises questions about banningiana as an ID. There is something I’ve called Amanitasp-N12” that is a possibility. The cap of the latter is broad (like your material) in the one known collection. I had the good luck to have some DNA sequenced from both banningiana and “sp-N12”…and they were quite different; however, the lab lost the information about “sp-N12” before they could share the data with me. So I am very interested in multiple fruiting bodies of your material. If it is found in more than one place, then I’d be very interested in having material from multiple localities as this will help with an understanding of the morphology and of the DNA.

See http://www.amanitaceae.org/?Amanita+sp-N12

As you can see, thee is not too much known about “sp-N12”, and the picture is crappy…I should rescan it after NEMF.

Very best,

Rod

Thanks to Dave and Rod

Thanks Dave and Rod. Rod, I have the ability to gather this specimen easily if this would be useful for you. Let me know. I also added another sharper stipe image that may be useful. Thanks, Mark

Do you have a dried specimen?

Cap color toward the margin…

is paler than for the A. banningiana I find here in NE PA. Otherwise, this obs looks like A. banningiana. Amount of yellow on the stipe has varied for my collections. Oak/hickory woods is a typical habitat for my collections. I have not noticed an association with coniferous trees.

Dr. Tulloss has mentioned that cap color is often an important trait for IDing the slender Amaerican Caesars. So I’m a bit hesitant to say “I’d call it that.”
