Basidiomycota is a large and diverse phylum of fungi that includes mushrooms, yeasts, jelly fungi, shelf fungi, puffballs, and stinkhorns. Basidiomycota is traditionally divided into two classes: Homobasidiomycetes (or true mushrooms) and Heterobasidiomycetes (jelly, rust, and smut fungi). Basidiomycota mushrooms are characterized by their club-shaped fruiting bodies called basidia, which are the reproductive organs of these fungi. These mushrooms are sometimes referred to as gill fungi due to the presence of gill-like structures on the underside of their caps. The gills are actually compacted hyphae on which the basidia are borne. So, yes, Basidiomycota mushrooms typically have gills.

Basidiomycota mushrooms are commonly seen in fields, supermarkets, and lawns
Basidiomycota is a large and diverse phylum of fungi that includes jelly and shelf fungi, puffballs, stinkhorns, certain yeasts, and the rusts and smuts. They are typically filamentous fungi composed of hyphae. Most Basidiomycota species reproduce sexually with a club-shaped spore-bearing organ (basidium) that usually produces four sexual spores (basidiospores). Basidia are borne on fruiting bodies (basidiocarps), which are large and conspicuous in all but the yeasts, rusts, and smuts.
Basidiomycota mushrooms can be found in fields, particularly after rain, and on lawns, where they often form a ring, commonly known as a "fairy ring". The body of the fungus, or mycelium, is underground and grows outward in a circle. As it grows, the mycelium depletes the soil of nitrogen, causing the mycelia to grow away from the centre and leading to the "fairy ring" of fruiting bodies where there is adequate soil nitrogen.
Basidiomycota mushrooms are also commonly found in supermarkets, where they are sold as edible fungi. Most edible fungi belong to the phylum Basidiomycota; however, it is important to note that some basidiomycetes produce deadly toxins. For example, Cryptococcus neoformans, a human pathogenic genus, causes severe respiratory illness. Therefore, it is crucial to properly identify mushrooms before consumption.
In addition to their presence in fields, lawns, and supermarkets, Basidiomycota mushrooms can also be found in various other environments, including forests and other natural habitats. They play an essential role in the ecosystem, contributing to nutrient cycling and decomposition processes.

They are also known as gill fungi due to their gill-like structures
Basidiomycota is a large and diverse phylum of fungi that includes mushrooms, jelly and shelf fungi, puffballs, stinkhorns, certain yeasts, and rusts and smuts. They are typically filamentous fungi composed of hyphae. Most species reproduce sexually through the fusion of two different mating strains, which is unusual among fungi.
Basidiomycota are easily recognizable under a light microscope by their club-shaped fruiting bodies called basidia. These are the reproductive organs of these fungi and are often contained within the familiar mushroom. The mushroom-producing basidiomyces are sometimes referred to as "gill fungi" due to the presence of gill-like structures on the underside of the cap. These "gills" are actually compacted hyphae on which the basidia are borne.
Basidiomycota typically reproduce sexually, with the club-shaped basidium carrying spores called basidiospores. In the basidium, nuclei of two different mating strains fuse to form a diploid zygote, which then undergoes meiosis to produce haploid basidiospores. These spores then germinate and generate monokaryotic hyphae, resulting in a primary mycelium.
Mycelia of different mating strains can combine to produce a secondary mycelium, which is the dominant dikaryotic stage of the basidiomycete life cycle. This secondary mycelium then generates a basidiocarp, a fruiting body that protrudes from the ground—this is what we typically think of as a mushroom. The basidiocarp bears the developing basidia on the gills under its cap.
Basidiomycota includes several gilled mushrooms, including Archaeomarasmius leggetti, Coprinites dominicana, and Protomycena electra, which have been found in amber fossils. Other gilled mushrooms include Aureofungus yaniguaensis and Schizophyllum commune.

The gills are compacted hyphae that bear the basidia
Basidiomycota, or club fungi, is a large and diverse phylum of fungi that includes jelly and shelf fungi, mushrooms, puffballs, stinkhorns, certain yeasts, and rusts and smuts. Basidiomycota are typically filamentous fungi composed of hyphae. Most species reproduce sexually with a club-shaped spore-bearing organ called a basidium. The basidium is the fruiting body of a mushroom-producing fungus, and it forms four basidiocarps.
Basidiomycota are easily recognizable under a light microscope by their club-shaped fruiting bodies. The basidia are the reproductive organs of these fungi and are often contained within the familiar mushroom. The gills are compacted hyphae that bear the basidia. These mushroom-producing basidiomycetes are sometimes referred to as "gill fungi" because of the presence of gill-like structures on the underside of the cap.
The lifecycle of a basidiomycete alternates between generations with a prolonged stage in which two nuclei (dikaryon) are present in the hyphae. In the basidium, nuclei of two different mating strains fuse (karyogamy), forming a diploid zygote that undergoes meiosis. The haploid nuclei migrate into basidiospores, which generate monokaryotic hyphae. The resulting mycelium is called a primary mycelium. Mycelia of different mating strains can combine and produce a secondary mycelium that contains haploid nuclei of two different mating strains. This is the dominant dikaryotic stage of the basidiomycete life cycle.
Eventually, the secondary mycelium generates a basidiocarp, a fruiting body that protrudes from the ground—this is what we think of as a mushroom. The basidiocarp bears the developing basidia on the gills under its cap. The gills are compacted hyphae that bear the basidia, and they are an important part of the mushroom's reproductive process.

Most edible mushrooms belong to the Basidiomycota phylum
Basidiomycota is a large and diverse phylum of fungi that includes jelly and shelf fungi, mushrooms, puffballs, stinkhorns, certain yeasts, and rusts and smuts. Basidiomycota are typically filamentous fungi composed of hyphae. Most species reproduce sexually with a club-shaped spore-bearing organ called a basidium, which usually produces four sexual spores (basidiospores). The basidia are borne on fruiting bodies (basidiocarps), which are large and conspicuous in all but the yeasts, rusts, and smuts.
Basidiomycota includes both edible and poisonous mushrooms, such as the cultivated button mushroom, Agaricus bisporus, and the ear fungus (Auricularia auricula-judae). The lifecycle of a basidiomycete alternates generation with a prolonged stage in which two nuclei (dikaryon) are present in the hyphae. Each basidium forms four basidiocarps, which are the fruiting bodies of mushrooms. The basidiocarp bears the developing basidia on the gills under its cap.
Basidiomycota can be distinguished from other fungi by the presence of specialized cells (basidia) bearing the spores. These cells are referred to as basidia, and their spores are called basidiospores. Some basidiospores are ballistospores, commonly found in mushrooms. Classification at the phylum level can be undertaken by looking for the presence or absence of basidia and basidiospores.
Basidiomycota includes the classes Urediniomycetes (rusts and relatives), Ustilagniomycetes (smuts), and Hymenomycetes (mushrooms and relatives). The relationships within these classes are controversial, and molecular studies suggest a greater degree of convergent evolution than previously thought.

Basidiomycota mushrooms reproduce sexually, requiring two different mating strains
The Basidiomycota mushrooms have some of the most complex systems of sexual reproduction known among fungi. The phylum Basidiomycota includes some of the most iconic fungal species, such as the gilled mushrooms, puffballs, and bracket fungi. Basidiomycota mushrooms reproduce sexually, requiring two different mating strains.
Basidiomycota mushrooms have two main types of sexual reproduction: homothallism and heterothallism. Homothallism is when mating occurs within a single individual, meaning each individual is self-fertile. Heterothallism is when hyphae from a single individual are self-sterile and need to interact with another compatible individual for mating to take place. Heterothallism is the most common mating system in Basidiomycota, with about 90% of the species being heterothallic.
Basidiospores play a crucial role in the sexual reproduction of Basidiomycota mushrooms. Each basidiospore germinates and generates monokaryotic haploid hyphae, resulting in a primary mycelium. Mycelia of different mating strains can then combine to produce a secondary mycelium that contains haploid nuclei from both parents. This secondary mycelium is the dominant dikaryotic stage of the Basidiomycota life cycle. The dikaryotic condition is maintained by a specialized structure called a clamp connection, which helps coordinate and re-establish compatible nuclei.
To initiate mating, a zygomycete hypha grows towards a compatible mate, and they form a bridge called a progametangia by joining their hyphal tips. Nuclear exchange and migration occur, resulting in the formation of dikaryotic hyphae containing haploid nuclei from both parents. Under suitable environmental conditions, these dikaryotic hyphae develop into a fruiting body that bears the developing basidia on its gills. Basidia are the reproductive organs of Basidiomycota mushrooms, typically producing four sexual spores (basidiospores).
The mating compatibility in Basidiomycota mushrooms is categorized into two types: tetrapolar and bipolar. Tetrapolarity refers to the presence of four haploid mating genotypes resulting from independent segregation of two compatibility factors. Bipolarity, on the other hand, involves two mating types, and approximately a quarter of mushroom species are bipolar.
