Why do mushrooms suddenly appear?

Mushrooms only grow when environmental conditions are just right. Prolonged periods of wet, humid weather, such as we have had over the past few weeks, cause fungi to send up fruiting structures. When the spores land in a suitable location they develop into new fungi which will grow mushrooms given enough time.
