That’s an Amanita all right, and it looks close to A. gemmata. Handle with care — probably poisonous, most likely with muscimol/ibotenic acid.

Amanita species of sect. Amanita…

Looks like a species of sect. Amanita. The marginal striations are short and the cap tissue is in patches suggesting it could be left as a flap on the stipe base. It seems to have done so. The annulus looks like its pretty weak and likely to disappear. Probably in the “gemmatoid group.” Spore measurements will be helpful to separate the subglobose-broadly-ellipsoid-spored species from the ellipsoid-elongate spored species.

From the color and structure of the volva, I’d say it’s probably not A. crenulata (which is very common at this time of year, usually). We’re getting zip rain around here. You’re lucky to be seeing stuff in the Long Island pine-oak forests.
