No specimen available

This is a small acorn brown colored mushroom. I noted mature Amanita’s close by that appear to be what this mushroom would look like when it is fully developed. Growing by a rotting stump in a stand of hardwoods Oaks and Sassafrass trees. The cap is shiney but not sticky becoming darker in shade towards the center, the white stipe is growing out of a cup shapped formation.

Recognized by sight: this is certainly one of the grisettes. IF sinicoflava (the cap striations that are approx. 40% of the cap length do fit that sp. description), then mature specimens would show graying on the volva (cup at the stem base). spore prints are not useful for separating amanita species, unless you also have a microscope to look a lot closer…the spore drop in all amanitas is pretty much always white.
grab a mature fruit body when you go out again, and post those photos, too.

not the European species, but…

I think this is what NE N. Amer. collectors/authors have been calling A. fulva. It needs a new name (in preparation).

Amanita sinicoflava has a no orange in the pileus. This specimen has a very typical volva for the N. American fulva, firm, white, and with rusty spots. The volva of sinicoflava become gray from the top down and crumbles into fragments as it grays and ages.

I think both taxa are pictured on the New Jersey Pine Barrens picturebook/checklist page of the Amanita Studies site:

ALso A fulva has a more yellower stipe. A sinicoflava is more meaty It looks like a buff A. fulva, it has a white stipe. The cup on the bottom is called a volva. When you go back check it there is an annulus ring. If there is. then it could be A banningiana. But usually they have a yellow stipe

An Amanita fulva is larger?

I will go back to the site I observed this mushroom to gather samples if they are still there. I am curious to note the sizes. I will also do a spore print as well. I compared the three images you refered me to,it seems my images of this mushroom are very similar in appearance.

It also could be

This could be A sinicoflava. A. fulva in my experience is a bit slimmer and lighter in color. It would be interesting to know if there is a annulus on that guy. Check out observation 21837 I think its similar.
