There are four main phases for the life cycle of mould. When the appropriate conditions for growth exist: presence of moisture, nutrients, temperature and oxygen, mould begins to reproduce via its life cycle.

Hypha Growth: Hyphae are the thread-like filamentous cells that release enzymes which degrade and absorb nutrients from a substrate (i.e. organic debris, cellulose, wood, almost any carbon containing material including human skin). Upon obtaining its nutrition, the hyphae will grow into a mycelium, the main body of the fungus which is also the visible portion.

Spore Formation: Spores form on the ends of some hyphae cells. The formation of spores is dependent on a variety of environmental factors including light, oxygen levels, temperature, and nutrient availability.

Spore Dispersal: After the spores are formed, they are released into the air and carried elsewhere to begin the process of germination and growth all over again. Mould spores are highly resistant and durable. They can remain dormant for years in even hot and dry environments.

Spore Germination: Once thespore is dispersed to a new area and when the appropriate conditions exist,moisture and nutrient availability, the spore will begin to germinate into a new hyphae cell. The life cycle of mould then begins again.
