1) DON'T EAT A MUSHROOM IF YOU DO NOT KNOW WHAT IT IS
1a) There are people here who will tell you to eat it before you post location, spore print, and bruise test.
2) Where on earth are you? Location matters when IDing species. Just your state / region is fine we don't need your home address so don't freak about somebody finding where you live and killing you.
3) Google "how to take a spore print". Take a spore print of the mushroom you found. Photo Document and post pics.
4) Pinch part of the cap, see if it bruises/changes color. Photo document and post pics.
Come back when you have done these things and then somebody here may be able to ID your mushroom.
