How Is Fungi Spread?
Fungi spread by forcibly ejecting spores, making their own wind and allowing natural wind and water to spread their spores. Some spores have hair-like parts that help them disperse more easily in water. Some fungi use insects, such as flies, to help them spread their spores.
For fungi whose habitat is underneath a forest canopy and has little wind, mushrooms are able to create their own wind by letting their moisture evaporate. Evaporation creates cool air, which is denser than warm air and has a tendency to spread out. Research shows that this process can lift spores up to four inches in all directions. Fungi that eject their spores can spread them when animals accidentally bump into their fruiting bodies or when raindrops fall on them.
