Abstract: Mushrooms are macroscopic fruiting bodies produced by ascomycete and basidiomycete fungi during their sexual reproduction cycles. This chapter discusses the general aspects of the life cycle of basidiomycetes, with an emphasis on sexual reproduction. It talks about the basic mechanisms that control breeding between basidiomycetes and the structures and external factors involved in the process. Ascomycetes and basidiomycetes are unique in the kingdom Fungi for the dikaryotic phase of their life cycle. A fungal species is considered heterothallic when its sexual spores germinate autosterile monosporic cultures. A fungus is considered homothallic when a colony originating from a single spore is able to complete its life cycle, producing fruiting bodies via autofertilization. The amphithallic species produce both homokaryotic and heterokaryotic spores. Two mating-type systems can be found in these species: bipolar system and tetrapolar system. The first work on the cytology of Agaricus brasiliensis showed that the hyphae of heterokaryotic cultures were multinucleated.
