Scientific American reports that mushrooms can create their own breezes to scatter spores:
Mushrooms must scatter their spores to make little mushrooms. And we’ve long assumed that they rely on a friendly breeze for spore spreading. But a new study shows that mushrooms can create their own spore-casting wind.
Fluid mechanics researchers trained high-speed video cameras on common Shiitake and oyster mushrooms. The scientists discovered that the mushroom spores floated off even when the air was calm. They enlisted mathematical models to solve the mystery.
Turns out that before the spore dispersal, the mushrooms released water vapor. This moisture cooled the air around the ‘shroom, causing a convective dynamic that got the air moving. Just this faint fungal breeze was enough to carry the spores away from the parent. The findings were presented at the Annual Meeting of the American Physical Society’s Division of Fluid Dynamics in Pittsburgh.
