Unformatted text preview: Sexual reproduction in Basidiomycota takes place in the fruiting body, in specialized structures called basidia. The basidia is itself formed by plasmogamy between mycelia from two different spores. Plasmogamy results in binucleate hyphae, that is, hyphae with two types of nuclei, one from each parent. In the gills of the fruiting body, some cells undergo fusion of these two nuclei. These now diploid cells are the basidia. The diploid phase is very brief. Soon after fusion, meiosis takes place, resulting in four haploid nuclei. The nuclei then migrate to the terminus of the basidium and form four individual projections. These projections are then separated by cell walls to become spores....
