Found on a blustery day in a bunch of about 10 or 12 other A. Muscarias.
Some had been chomped by local animals but most caps were intact ranging about 6-10 inches in diameter, some with universal veil patches on the cap and some without.
Found them on a sandy berm hidden in dune grass with Sitka Spruce nearby.
ID was helped by posting this on mushroomobserver.org
NOT SURE of ID
Possibly sp. virosa
This was under a valley oak. I found it kicked up like this (I wouldn't remove a singular specimen like this)
