Mushrooms can create air currents to actively scatter their spores

It has long been thought that mushrooms allow moving air currents to lift their spores and transport them far away to reproduce, however investigations show that mushrooms can actually create their own breeze to actively move their spores even when there is no wind to do this for them passively.

Before spore dispersal, the mushrooms release water vapour, cooling the air next to it, and creating a convection current in the air. This is enough to lift the spores which are subsequently released into the air, for dispersal.
