Mating in fungi is a complex process governed by mating types. Research on fungal mating has focused on several model species with different behaviour. [3] [4] Not all fungi reproduce sexually and many that do are isogamous; thus, for many members of the fungal kingdom, the terms "male" and "female" do not apply.
Even among fungi that reproduce both sexually and asexually, often only one method of reproduction can be observed at a specific point in time or under specific conditions. Additionally, fungi typically grow in mixed colonies and sporulate amongst each other. These facts have made it very difficult to link the various states of the same fungus.
There are also single-celled fungi that do not form hyphae, and some fungi have both hyphal and yeast forms. [34] In common with some plant and animal species, more than one hundred fungal species display bioluminescence. [35] Unique features: Some species grow as unicellular yeasts that reproduce by budding or fission.
Most fungi can produce asexually and sexually. Currently, sexual selection has been studied to occur more predominantly in the Ascomycota and Basidiomycota phyla. Although different sexes are not present within fungi, sexual selection can act due to the presence of different sex roles as well as different mating types as most fungi are hermaphroditic. [1]
In biology, a spore is a unit of sexual (in fungi) or asexual reproduction that may be adapted for dispersal and for survival, often for extended periods of time, in unfavourable conditions. [1] Spores form part of the life cycles of many plants, algae, fungi and protozoa. [2]
Reproduction via spores involves the spreading of the spores by water or air. Algae and some fungi often use motile zoospores that can swim to new locations before developing into sessile organisms. Airborne spores are obvious in fungi, for example when they are released from puffballs. Other fungi have more active spore dispersal mechanisms.

Asexual reproduction is the dominant form of propagation in the Ascomycota, and is responsible for the rapid spread of these fungi into new areas. Asexual reproduction of ascomycetes is very diverse from both structural and functional points of view.
