I’m new to identifying mushrooms, but apparently this is a poisonous mushroom that causes death by liver failure from eating just one. Identifying features: has a smooth white cap (sometimes with a tan tint in the center, like this one), gills, and a drapy skirt-like ring near the cap. The first stage of poisoning is called the incubation stage: 6-12 hours with no symptoms while it takes over without you noticing. Don’t eat white mushrooms!
