It would be hard to overstate the importance of fungal/mycelial networks for creating healthy soil, optimum conditions for plant growth, and remarkably: rain. The role of mushrooms in nutrient and water cycles is profound. Mycelium networks bind soil, break down dead plants and animals, and network nutrients so that plants thrive. This allows soil to hold more water—a blessing that is shattered by annual tillage of land for new crops. Mycologist Paul Stamets explains, “Mycelium is the immune system of the mushroom.” Additionally, trillions of fungal spoors released into the air act as rain seeds, helping create clouds.
