The majority of Armillaria species have a bifactorial heterothallic mating system. Some primary homothallic and secondary homothallic behaviour has been observed in a small number of different A. mellea and A. heimii strains from Africa and Asia. In a typical bifactorial heterothallic Armillaria species four haploid nuclei are produced in the basidia during meiosis and the subsequent migration of each nucleus produces haploid basidiospores.

Although it is known that A. luteobubalina is a bifactorial heterothallic species the nuclear life cycle is not thoroughly described. This present study aimed to investigate the cytology and nuclear arrangement within the different basidiome tissues and basidiospores in A. luteobubalina.
