Underneath the earth, spanning hundreds of miles below our feet, is a massive colony. Often referred to as the “internet of fungus”, this vast system of roots has the ability to connect with plants several miles away. Mycelium, the living body of a mushroom, is made up of a web of tiny filaments. It allows fungi, and other species, to communicate with each other. It helps plants receive water and nutrients and it can even help protect plants against certain infections. While all of this is happening below the ground, the mushroom we see above the earth is just as fascinating.
