In Ascomycetes and Basidiomycetes, plasmogamy is not immediately followed by karyogamy as a result a dikaryotic cell is produced. In ascomycetes, the dikaryotic cell divides to form small dikaryotic hyphae known as ascogenous hyphae, which produces ascospores, in Basidiomycetes the dikaryotic cell divides to form a well developed dikaryotic mycelium, which produces basidium at a later stage.
