It is a complex of species of which many North American species have been incorrectly given European names. Your pic looks a bit like what may be called Amanita amerifulva (a provisional name). It would be Amanita fulva in most books. If the stipe had “snakeskin” bands of orange tan then you have something close to Amanita crocea.
