How It Works


(my·ce·li·um \mī-ˈsē-lē-əm\)

the mass of interwoven filamentous hyphae that forms especially the vegetative portion of the thallus of a fungus and is often submerged in another body (as of soil or organic matter or the tissues of a host)

A.K.A. — mushroom roots

Our Process

Receive agricultural waste purchased from regional farmers.

Clean the agricultural waste and introduce it to mycelium.

Bag this mixture and let the mycelium grow for a few days. The mycelium sees the agricultural waste as food and reaches out to digest it, forming a matrix of white fibers along the way.

Each particle is now coated in mycelium and we break it up into loose particles again.

Loose particles are put into a tool where the mycelium grows through and around the particles, forming a solid structure and filling any void space. We let this grow for a few days until it is solid, and then remove it from the tool.

Materials are dried to stop growth and prevent it from producing mushrooms or spores.

Mushroom® Materials do not degrade without exposure to living organisms, such as that found in soil biota, and moisture. You can think of it like an unfinished piece of wood. A wooden table isn’t going to decompose without exposure to the right conditions. Like most things you’d keep in your home or in a warehouse, Mushroom Materials will last. But if you leave that wooden table outside, or put wood chips into a compost pile, it will naturally decompose. The same is true with Mushroom Materials.
