Patterns of mating and mitochondrial DNA (mtDNA) inheritance were investigated for the Basidiomycete, Coprinus cinereus in order to better understand the relationship of reproductive biology and mtDNA evolution in fungi. Results showed that the unique mating system of basidiomycetes can lead to the formation of mitochondrial mosaics (i.e., colonies composed of sectors differing in mtDNA). Mitochondria do not migrate along with nuclei during mating. Intracellular mixed or recombinant mtDNA molecules were not observed. Interestingly, it was found that mating asymmetry, caused by nonreciprocal nuclear migration, may be an important part of the reproductive biology of C. cinereus.
