Why do fungi release so many spores at once?

A fungus cannot move to find food or mates, so it relies on dispersal. By making millions or even billions of microscopic spores, it greatly improves the odds that a few will reach a suitable habitat. This strategy is visible in puffballs, bracket fungi, and molds, which can spread spores through wind, water, animals, or explosive release. Spores are often tiny, light, and resistant to drying, allowing them to travel long distances. The enormous numbers reflect a basic evolutionary trade-off: quantity compensates for very low survival rates.
