This is Amanitas Muscaria:

FWIW:

Wikipedia:

"Although it is generally considered poisonous, deaths from its consumption are extremely rare, and it is eaten as a food in parts of Europe, Asia, and North America after parboiling. Amanita muscaria is noted for its hallucinogenic properties, with its main psychoactive constituent being the compound muscimol."

BTW: I love the first photo.
