In basidiomycete fungi, the nuclei from parents combine in the BASIDIA to make offspring spores. Basidia are microscopic structures but they are generally produced on large fructifications known as fruit bodies.
A basidium is a sporangium localized on the hymenophore of the fruiting bodies in basidiomycete fungi.
In basidia, the nuclei of two parental strains fuse by karyogamy and then divide to reproduce basidiospores.
A basidium generally contains four sexual spores known as basidiospores.
