Could be a variety

of either species or one of the numbered species on the Amanita website with color variations. If I find it again perhaps Rod may be interested in analyzing it. Can’t really be definitive about it until more data is available.

all of the fairly large brightly colored (reddish/yellowish/orangish) “Caesars” I find locally either banningiana or jacksonii. Banningiana is by far the most common locally (in my experience). But I think there’s reason to suspect there being a somewhat cryptic species that exhibits traits associated with both banningiana and jacksonii. Consider this collection made in CT. obs 74437.

A few hundred miles south of NE PA there seems to be at least one such reddish Caesar that may be different from either banningiana or jacsonii. There are plenty of representative obses here on MO. One example obs 85534.

Some of what I have called banningiana has a disc color tending toward orange/reddish. I may need to revise my own concept of this species.

every species under Amanita sect. Caesarea on the Amanita website and reached the conclusion that this is either A. jacksonii or A. banningiana. I would lean towards A banningiana due to its stipe matching this species more so than Aj, and the gills on this match Ab. much better. I’m taking liberties with abbreviations of species. Also the pileal color of Aj is a deep red and I don’t think it would fade this much in a heavy forest canopy, and the area was damp and held moisture in the soil quite well. Checked all of the species under stirps hemibapha to which I believe this species is to be found. If I find it again this year I’ll try to obtain spore sizes and any other pertinent information.

I think there’s too much yellow on the gills…

and too much red on the cap for banningiana. Also, in my experience, banningiana has a white annulus.
