Amanita muscaria. Most species of Amanita are poisonous: some are "deadly," meaning "kill you for sure," but muscaria's poison is a powerful neurotoxin. Don't eat wild mushrooms unless they've been identified by an expert! The real mushrooms don't always look like the ones in the book; unusual examples of one species may look a lot like some other less desirable species; and the same species may vary in appearance and toxicity from place to place.
i havent seen them in quite some time, seem to remember thinking they sprouted and rotted within the week at home. and almost overnight the yard was full of them
