Spores
Fungi can reproduce both sexually and asexually, with or without a partner, but only sexual reproduction results in the production of spores, which require winds. Asexual reproduction is where another fungi starts growing from a parent. Sexual reproduction occurs when male and female cells come together to produce spores.
Depositing
The first method of expelling the spores is when a fungus simply drops them on the floor. Underneath any fungi head there are many gills. Between these gills, spores are held and when they are ready the gills open and the spores fall out.
Ejection
Other fungi have evolved a different way of ejecting spores. The puffball fungus, for example, opens when the spores are ready and waits for rain to fall. Rain drops hitting the fungus cause a plume of powder to be released. This powder is in fact a cloud of spores.
Air Currents
After the spores have been released, it is up to the wind to disperse them. Regardless of whether the spores are deposited on the ground or forcibly ejected, the wind blows them to another area where they will settle, grow and reproduce. It is entirely up to the prevailing air currents at the time where the next batch of a fungus gene will grow.
