Mushrooms are a part of the kingdom Fungi, which includes a diverse range of organisms, from simple, single-celled organisms to complex, multicellular ones. Fungi are eukaryotic organisms, meaning their cells contain membrane-bound organelles and well-defined nuclei. They are distinct from plants and animals due to their unique structural and physiological characteristics, including the absence of chlorophyll and the presence of chitin in their cell walls. Fungi, including mushrooms, play a crucial role in ecological systems as primary decomposers and degraders of organic matter. They acquire their food by absorbing dissolved molecules and growing from the tips of filaments (hyphae) that form their bodies. Mushrooms specifically are reproductive structures used by many types of fungi, although not all fungi produce mushrooms. The kingdom Fungi is further classified into seven phyla, with Basidiomycota and Ascomycota being the most species-rich and familiar groups, including mushrooms and other organisms.

Mushrooms are a reproductive structure used by many fungi
The word "fungus" comes from the Latin word for mushroom. Indeed, the mushroom is a reproductive structure used by many types of fungi. However, there are also many species of fungi that do not produce mushrooms. Fungi are eukaryotic organisms, meaning their cells contain membrane-bound organelles and clearly defined nuclei. They are classified as one of the traditional eukaryotic kingdoms, separate from plants, animals, bacteria, and some protists. Fungi, unlike plants, lack chlorophyll and are unable to make their own food through photosynthesis. Instead, they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment.
Mushrooms are the most familiar form of fungi, with some of the most commonly cultivated edible mushrooms being shiitake, oyster, wood ear, and button mushrooms. They are characterized by their growth as septate hyphae, or branching filaments. The phylum Basidiomycota, or club fungi, produce showy fruiting bodies that contain club-shaped fruiting cells known as basidia, which produce specialized sexual spores called basidiospores. Most familiar mushrooms, including many of those sold in supermarkets, belong to this phylum.
The kingdom Fungi is composed of seven phyla, two of which are contained within the subkingdom Dikarya: Ascomycota and Basidiomycota. The phylum Ascomycota contains members commonly known as ascomycetes or sac fungi. Fungi in this phylum include most food-spoilage molds, plant pathogenic fungi, and the yeasts used in beer, wine, and bread production. In addition to mushrooms, yeasts, and molds, the kingdom Fungi also includes black mold and the producer of the antibiotic penicillin, Penicillium notatum.
Fungi are very diverse, ranging from simple, single-celled organisms to complex, multicellular organisms. They are the principal decomposers in ecological systems and are responsible for turning dead plants into small nutrient building blocks that other organisms can use. They come in three basic shapes: unicellular yeasts, filamentous hyphae (molds), and flagellated, swimming, unicellular organisms that encyst to form sporangia. Some fungi exhibit dimorphism, possessing a mixture of multicellular filamentous hyphae and unicellular yeast structures, depending on the growth conditions.

Fungi are eukaryotic organisms, with membrane-bound organelles and defined nuclei
Mushrooms are a part of the kingdom Fungi, which is composed of seven phyla: Basidiomycota, Ascomycota, Glomeromycota, Neocallimastigomycota, Blastocladiomycota, Chytridiomycota, and Microsporidia. Fungi are eukaryotic organisms, meaning they have a complex cellular organization. As such, their cells contain membrane-bound organelles and clearly defined nuclei.
Fungi were historically included in the plant kingdom due to similarities in lifestyle and morphology. However, they have been reclassified as a separate kingdom because they lack chlorophyll and possess unique structural and physiological features, such as the presence of chitin in their cell walls. Fungi also differ from plants and animals in their modes of vegetative growth and nutrient intake. They grow from the tips of filaments (hyphae) that make up their bodies (mycelia) and digest organic matter externally before absorbing it.
Fungi come in three basic shapes: unicellular yeasts, filamentous hyphae (molds), and flagellated, swimming, unicellular organisms that form sporangia. They can also exhibit dimorphism, changing from a unicellular to multicellular state depending on environmental conditions. Most fungi are multicellular and display two distinct morphological stages: the vegetative stage, consisting of a tangle of slender thread-like structures (hyphae), and the more conspicuous reproductive stage.
Fungi are primarily composed of water (69-90%), carbohydrates, proteins, and lipids. They are ecologically important as they are the principal decomposers in ecosystems, breaking down dead organic material into small nutrient building blocks that other organisms can use. Fungi reproduce by forming and releasing spores, which are usually single cells produced through asexual or sexual reproduction. These spores may be nonmotile or possess flagella, enabling them to swim or travel through the air or water to disperse and form new fungal individuals.

Fungi are not plants, they lack chlorophyll and have unique structural and physiological features
Mushrooms are a part of the kingdom Fungi, which encompasses a diverse range of taxa with varied ecologies, life cycle strategies, and morphologies. Fungi, including mushrooms, were historically classified as part of the plant kingdom due to similarities in lifestyle, morphology, and growth habitat. However, it is now understood that fungi, including mushrooms, are distinct from plants and belong in their own kingdom.
Fungi, including mushrooms, lack chlorophyll, which is a key photosynthetic pigment found in plants. This is one of the primary reasons why fungi are classified separately from plants. Fungi are heterotrophs, which means they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. They do not photosynthesize like plants and other autotrophic organisms.
In addition to their distinct nutritional and reproductive strategies, fungi possess unique structural and physiological features that set them apart from plants. Fungi are composed primarily of water (69-90%), carbohydrates, proteins, and lipids. They grow from the tips of filaments (hyphae) that make up their bodies (mycelia) and digest organic matter externally before absorbing it. This mode of vegetative growth and nutrient intake is unique to fungi and distinguishes them from plants and other organisms.
Furthermore, fungi, including mushrooms, have chitin in their cell walls, which is not found in plants. Chitin is a characteristic that places fungi in a different kingdom from plants, bacteria, and some protists. While mushrooms and other fungi may superficially resemble plants, their underlying structural and physiological characteristics are unique and distinct from those of plants.
The kingdom Fungi is vast and diverse, with an estimated 1.5 million to 3.8 million species, of which only about 148,000 have been described. Mushrooms are a familiar and well-studied part of this kingdom, with some species being edible, such as shiitake, oyster, and button mushrooms, while others are toxic. The study of fungi, including mushrooms, is known as mycology, derived from the Greek word for mushroom, "mykēs."

Fungi are spread across three kingdoms: Protoctista, Chromista, and Eumycota
The classification of fungi has been a subject of debate for centuries. While they were historically included in the plant kingdom, fungi are now considered a separate kingdom, distinct from both plants and animals.
The kingdom Fungi is composed of seven phyla: Basidiomycota, Ascomycota, Glomeromycota, Neocallimastigomycota, Blastocladiomycota, Chytridiomycota, and Microsporidia. Mushrooms, which are a part of the kingdom Fungi, belong to the phyla Ascomycota and Basidiomycota, which are contained within the subkingdom Dikarya. This group also includes most food-spoilage molds, plant and human pathogenic fungi, and the yeasts used in bread, wine, and beer production.
The word "mushroom" is derived from the Latin "fungus" and the Greek "mykēs", which refer to the macroscopic structures and morphology of mushrooms and molds. Mushrooms are a diverse group, ranging from large, edible mushrooms like shiitake and oyster mushrooms to smaller, poisonous toadstools. They are a source of fiber and protein, have a well-balanced composition of minerals and vitamins, and are low in calories.

Mushrooms are a part of the Basidiomycota phylum, which includes most edible mushrooms
Mushrooms are a part of the kingdom Fungi, which consists of eukaryotic organisms that include microorganisms such as yeasts and molds. Fungi are distinct from plants and animals, having diverged from the latter around one billion years ago. They are characterised by their unique modes of growth and nutrient intake, as well as the presence of chitin in their cell walls.
The kingdom Fungi is composed of seven phyla, two of which are Ascomycota and Basidiomycota, both contained within the subkingdom Dikarya. Basidiomycota is a large and diverse phylum of fungi that includes jelly and shelf fungi, puffballs, stinkhorns, certain yeasts, and the rusts and smuts. Basidiomycota are typically filamentous fungi composed of hyphae.
Basidiomycota is characterised by the presence of club-shaped fruiting cells known as basidia, which produce specialised sexual spores called basidiospores. Each basidiospore germinates and generates monokaryotic haploid hyphae, which combine to produce a secondary mycelium with haploid nuclei from two different mating strains. This is the dominant dikaryotic stage of the basidiomycete life cycle, during which the secondary mycelium generates a basidiocarp, or the fruiting body of a mushroom-producing fungus.
Most edible mushrooms belong to the phylum Basidiomycota, although some basidiomycetes produce deadly toxins. Examples of edible mushrooms within this phylum include the cultivated button mushroom (Agaricus bisporus), as well as shiitake (Lentinula), oyster mushroom (Pleurotus), and wood ear mushroom (Auricularia).
