Amanita xanthocephala does not have an annulus (ring). Thought it might have been A. flavella, though annulus doesn't look right, too robust and there doesn't seem to be enough yellow in whole stipe/annulus!! Though specimen rather washed out so hard to say.
@Pam ahhhh true, I forgot that detail. Flavella didn't fit, as you said, too much striation on the pileus. Almost looked like a Russula apart from that annulus!
