It was definitely young. I have pictures of older ones in the area and they are much bigger

I think it could be an immature one. Look at the dirt around it for scale. It’s very small.

Not an Amanita Pantherina. A. Pantherina has a less abrupt bulb at the base of the stem and has a small collar on it's bulb. Not sure what yours is though.

This is more likely to be a variation of Amanita rubescens I would imagine, especially with that basal bulb attachment. Always hard to tell in immaturity but I don’t believe it’s A. pantherina

Some sort of Amanita. Possibly pantherina
