How do puffballs release their spores?

Puffballs release their spores through a passive mechanism. These fungi produce their spores internally within a spherical fruiting body known as a basidiocarp. Once the fruiting body reaches maturity, its internal tissues become dry and powdery. When these tissues are physically disturbed—such as by raindrops, wind, or contact with animals—the spores are ejected in visible puffs.1
