When mushroom spores or spawn are introduced to a moist, cellulose-rich material like paper, the mycelium begins to colonize, creating a white network that acts as the "root" system. The boiling process shown at the start is crucial; it reaches temperatures high enough to kill off mold spores that would otherwise ru
