I'm fairly certain that this is (or a close relative of) a Destroying Angel #mushroom (Amanita sp.). https://richard.rathe.org/travel/iowa/pikes_peak_2026/index.html A GIlled mushroom with an annulus (ring on stem), and probably a volva under the leaves. DO NOT PICK mushrooms that look like this! https://en.wikipedia.org/wiki/Amanita_verna #Fungi #NaturePhotography
