This guy is not an amanita as it grows from wood and lacks a stem ring. I think it is Volvariella bombycina as the egg and fuzzy cap give it away along with the pink gills. The cap color can range from yellow to white as well. Possibly yellow when younger? I've only seen it in it white stage. Also they're edible
