ABSTRACT
Each of the fungal groups is characterized by differences in their life cycles. All fungi are characterized by having a period of vegetative growth where their biomass increases. The length of time and the amount of biomass needed before sporulation can occur vary. Almost all fungi reproduce by the production of spores, but a few have lost all sporing structures and are referred to as mycelia sterilia. Different types of spore are produced in different parts of the life cycle.
