Dubbed the Foolproof Four? in 1943 by Professor Clyde Christensen, Morel, Shaggy Mane, Puffball and Sulfur Shelf mushrooms are the most common and easily identified edibles hunted by amateur mycologists. The term Foolproof Four led Dunning to consider mushrooms as actual superheroes of the natural world. Like all fungi, these mushrooms contribute to planetary survival by providing the imperative function of decay. Culturally, they are weighted with similar dark, mysterious and supernatural characteristics as bats, spiders and cats, on which popular comic book superheroes have been based.
