Mushrooms with gills have meiotically produced spores located in Basidia or on Basidiomycota.
Many mushrooms produce spores on their gills (on the underside of the mushroom's cap).
The sole purpose of these gills/lamellae, is to produce spores. The spores are then dropped from the gills by millions in numbers, where they are scattered by wind currents.
Basidiomycota are filamentous fungi composed of hyphae (except for basidiomycota-yeast) and reproduce sexually via the formation of specialized club-shaped end cells called basidia that normally bear external meiospores (usually four). These specialized spores are called basidiospores.
