“Mycelium is what you would think of as the root structure of a mushroom. So when you see a mushroom in the woods, whether it’s coming out of the ground or growing on a tree, that’s actually like a tiny portion of the mushroom’s total biomass, its size, and its lifecycle. Mycelium is the underground network, and it acts as a recycling system in nature, breaking down leaves and twigs to turn it into soil. It also acts as a network to move nutrients, food, and information, even between roots and trees. It also can help stabilize a forest floor, much like roots could. The way we use mycelium is as a material. We actually grow it into things.”
