Recognized by sight: This would be the only record on MO of Amanita section Amidella in California, and that makes me suspicious. The oak habitat and reddish cast to the top of the cap point towards Amanita ocreata.

if you had pulled off that volva, you would have no doubt seen a bulb, typical of section Phalloideae. Amidellas have wholly elongating stipes, just like grisettes and caesars.

don’t let that appendiculate margin throw you off!

we sometimes see it in a number of species in section Phalloidea, even tho it’s not “supposed to” occur!

ocreata often has color in the center of its cap: fror this pink, to a velosa orange to yellow to even brown. not quite a “pure white” destroying angel! those mushrooms don’t read our books and websites!

I have also seen A. bisporigera in the SE with a pink cap, that example also illustrated here on MO. Bill Roody told me that he sometimes sees it in pink, too.

Greg Wright and, later, me. This species is called Amanita fallax Tulloss & G. Wright nom. prov. on the WAO site.

On the other hand, I think that the material of this observation is more likely to be Amanita ocreata because that species is known to show a pink “blush” (good word) on the cap sometimes.
