Basidiomycetes, or club fungus, is the most recognizable fungus because of its large fruiting body. Unlike many other types of fungi, basidiomycetes have a long lived dikaryotic . Some mycelium can survive for centuries. The "gills" that are found on the underside of the mushroom contain thousands of basidia.

Hyphae of two different mating come together to fuse in plasmogamy to form a dikaryotic cell. This cell will then form an expansive dikaryotic mycelium that usually outgrows either of the parent mycelium. When exposed to certain environmental stimuli, a basidiocarp, or mushroom, is formed. The 'gills' on the underside of the basidiocarp are lined with terminal dikaryotic hyphae cells called basida. Within basidia cells, the two nuclei will fuse together to create diploid cells that will soon go into meiosis, creating many haploid spores. These spores will then be dispersed and germinate into haploid mycelia, thus restarting the cycle.
