The largest living organism on the planet is a mushroom. You can make a hat out of a boiled mushroom called Amadou, or as our ancestors once did, you can use it as tinder to start a fire. With that fire, you might cook up one of the many delicious edible mushroom varieties. But choose the wrong one and you’ll get sick or die.
Mushrooms may also be powerful medicine.
