The 2007 classification of Kingdom Fungi is the result of a large-scale collaborative research effort involving dozens of mycologists and other scientists working on fungal
Sexual reproduction
Ascomycota
The phylum
Basidiomycota
The phylum Basidiomycota can be divided into three major lineages: mushrooms, rusts and smuts. Fusion of haploid nuclei (karyogamy) occurs in the basidia, club-shaped end cells. Shortly after formation of the diploid cell, meiosis occurs and the resulting four haploid nuclei migrate into four, usually external cells called basidiospores.
Adaptive function
Sexual reproduction has been proposed to have evolved in both the Ascomycota and Basidiomycota as an adaptation for repair of DNA damage via homologous recombination under stressful conditions.[6]
