99% underground, 100% fresh and local.

Located in the heart of Capitol Hill in Seattle, WA, we supply our local community, friends, neighbors, and family with a variety of fresh mushrooms for sale, as well as mushroom tinctures, extracts, spawn, and even mushroom grow kits.

MarrowStone Mushrooms may have officially launched in 2022, but our local mushroom company is the culmination of over five years of mushroom cultivation, research, and hard work.

Are you a farm, landscaper, artist, or general fool looking to expand the scope of our mushroom production? Don’t be shy. Reach out..

Everyone deserves access to food, education, and pleasure. With mushrooms as our teachers, we’ve found all three, and now we want to share these fungal wonders with our community.
