WebThe three phases clearly encountered in the sexual cycle of the Ascomycetes are haplophase, dikaryophase, and diplophase. Just like all fungi the diplophasic condition in the Ascomycetes is very brief. Meiosis follows immediately after karyogamy producing haploid nuclei and reinstating haploid condition. There is wide diversity in the methods ... WebPlasmogamy occurs when secondary mycelium is initiated. Karyogamy is delayed due to the extensive dikaryophase. Eventually, the karyogamy occurs in the basidia formed by the terminal cells of the dikaryotic secondary mycelium, or in teliospores, and the promycelium.
