The super mushroom is the very first power-up you encounter in the entire game and that’s probably not by accident. Nearly every mushroom in Mario’s expansive world is modeled after the real-life mushroom Amanita muscaria. The common names of many of the poisonous Amanita mushrooms include foreboding monikers like death cap mushroom and destroying angel.
