First, you need a substrate, which is a bed of organic matter with nutrients that are specific to the mushroom species you wish to grow. Second, you need spores that come from a mushroom of that species. Third, you need the right conditions, such as temperature and humidity, for the spore to begin growing fungus on the substrate. Once the fungus matures, it will begin growing a mushroom to reproduce more spores. Once the mushroom matures, the spores will be released from underneath the mushroom cap.
