However, the dikaryotic phase is more extensive in the basidiomycetes, often also present in the vegetatively growing mycelium. This ejection ensures exit of the spores from the reproductive structures as well as traveling through the air over long distances.

These structures aidKaryogamy in the asci is followed

Mycelial fragmentation occurs when a fungal mycelium separates into pieces, and each component grows into a separate mycelium. Mycelia grown on solid agar media in laboratory petri dishes are usually referred to as colonies.

Karyogamy in the asci is followed immediately by meiosis and the production of ascospores. These structures aid reproduction by efficiently dispersing spores or spore-containing propagules. These colonies can exhibit growth shapes and colors due to spores or pigmentation that can be used as diagnostic features in the identification of species or groups. These sporangiospores allow the fungus to rapidly disperse and germinate into new genetically identical haploid fungal mycelia.

Efforts among researchers are now underway to establish and encourage usage of a unified and more consistent nomenclature. Compatible haploid hyphae fuse to produce a dikaryotic mycelium.

After dispersal, the ascospores may germinate and form a new haploid mycelium. Asexual reproduction Asexual reproduction occurs via vegetative spores conidia or through mycelial fragmentation. Fungal fossils are difficult to distinguish from those of other microbes, and are most easily identified when they resemble extant fungi. The bird's nest fungi use the force of falling water drops to liberate the spores from cup-shaped fruiting bodies.
