As in all macrofungi, there is the formation of sexual spores, which lead to a combination of genetic information from two parents. The sexual reproduction in Ascomycetes is as follows: The hyphae of two different mating types come together and fuse, Plasmogamy happens, but it will not immediately follow karyogamy. WebThe ascogenous hyphae and dikaryotic cells from which they are developed together with the ascus mother cells represent the dikaryophase in the life cycle of Peziza.
