This Nigerian mushroom (Pleurotus tuber-regium) forms a "ball" (called a sclerotium) allowing it to rest for months. To activate, simply bury in sand or gravel in the included container as pictured and mist once or twice a day. Boing! Mushrooms will sprout, forming spikes and then grow like the crazy fun-guys that they are. This mushroom kit is certain to amaze you and your family. A 70° F environment is needed.
