Mushrooms are commonly mistaken for vegetables or fruits. However, mushrooms are not plants and therefore cannot be fruits or vegetables. Mushrooms are fungi, and they have been given their own kingdom due to the large number of species that exist. They are the reproductive structures of fungi and are often referred to as fruiting bodies because the word fruit refers to analogous structures in botany. Mushrooms develop from a nodule or pinhead, typically found on or near the surface of a substrate, and they do not need light to grow.

What You'll Learn
Mushrooms are fungi, not plants
Mushrooms are not fruits, nor are they vegetables or plants. They are fungi, belonging to their own kingdom, separate from plants. While mushrooms are often referred to as "fruiting bodies", this is a residual term from when they were considered plants. The word "fruit" is a botanical term referring to the result of reproduction in plants, which does not apply to mushrooms.
Mushrooms are the reproductive structures of fungi, and they develop from a nodule or pinhead called a primordium, typically found on or near the surface of a substrate. This primordium enlarges into a round structure called a "button", which then ruptures and expands into the mushroom we commonly see. The process of mushroom formation is quite different from that of fruits, which evolve from the ovary around a seed, whereas mushrooms contain spores that mature and are dispersed.
Fungi, including mushrooms, have their own unique characteristics that distinguish them from plants. For example, mushrooms lack chlorophyll, which is a key feature of plants, enabling them to convert sunlight into energy. Instead, mushrooms obtain their carbohydrates by extracting them from other plants. Additionally, mushrooms grow and expand rapidly by absorbing fluids and spread in distinct ways, forming massive underground networks that can cover large areas.
While mushrooms may be commonly found in grocery stores and cooked like vegetables, they are not plants. They belong to the kingdom of fungi and have their own distinct reproductive and growth processes. The term "fruiting bodies" for mushrooms can be misleading, as it is a holdover term from historical botanical classification. However, in technical and botanical terms, mushrooms are unequivocally classified as fungi.

Mushrooms are the reproductive structures of fungi
Mushrooms are not fruits, despite what their name might suggest. They are also not vegetables. Mushrooms are the reproductive structures of fungi. Fungi are a separate kingdom from plants and animals, and mushrooms are the reproductive structures of these organisms. The part of the fungus that we typically refer to as a "mushroom" is called a "fruiting body", a term that comes from botany. This is because mushrooms are where spores are produced and dispersed, similar to how fruits contain seeds. However, mushrooms do not contain seeds and do not evolve from the ovary of a plant, which is how fruits are formed. Instead, mushrooms develop from a nodule called a primordium, typically found on or near the surface of a substrate, and formed within the mycelium, the mass of thread-like hyphae that make up the fungus.
Mushrooms are typically found above ground on soil or another food source, and they can grow or expand very rapidly. This has led to the use of the word "mushroom" in expressions such as "to mushroom" or "mushrooming" to describe something expanding rapidly in size or scope. While mushrooms are commonly cooked and eaten like vegetables, they are not plants and do not contain chlorophyll. Instead, they extract carbon dioxide and minerals from their environment and steal carbohydrates from plants.
The term "mushroom" is typically used to refer to the fleshy fruiting bodies of some Ascomycota and Basidiomycota, specifically those with a stem (stipe), a cap (pileus), and gills (lamellae) on the underside of the cap. However, the term is also used more loosely to describe various other fungal fruiting bodies, including polypores, puffballs, jelly fungi, and stinkhorns, among others. These deviations from the standard morphology often have more specific names, such as "bolete", "truffle", "morel", or "agarics".
The gills or pores of mushrooms produce microscopic spores, which help the fungus spread across the ground or its occupant surface. These spores are called basidiospores, and they are shot off from the basidia, falling in a fine rain of powder from under the caps. This process results in a powdery impression called a spore print, which is useful for classifying and identifying mushrooms. Spore prints can be various colours, including white, brown, black, purple-brown, pink, yellow, and creamy, but they are almost never blue, green, or red.
In conclusion, mushrooms are the reproductive structures of fungi, and while they may be colloquially referred to as "fruiting bodies", they are not fruits in a botanical or culinary sense. They have their own kingdom, separate from plants and animals, and their unique characteristics and methods of reproduction set them apart from other life forms.

Mushrooms are called fruiting bodies
Mushrooms are not fruits, despite what some people may think. Fruits are the result of the reproduction of plants, whereas mushrooms are the reproductive structures of fungi, which are a separate kingdom of life. Mushrooms are often referred to as "fruiting bodies", but this is a residual term from when they were considered plants.
The word "fruit" refers to analogous structures in botany, and since fruit is a botanical word, mushrooms cannot be considered fruit in a technical sense. Mushrooms do not contain chlorophyll, which is a key characteristic of plants, and they do not have seeds. Instead, mushrooms produce spores, which are dispersed to help the fungus spread across the ground or its occupant surface.
Mushrooms develop from a nodule or pinhead, called a primordium, which is typically found on or near the surface of a substrate. This enlarges into a round structure called a "button". The button has a cottony roll of mycelium, which is the mass of thread-like hyphae that make up the fungus. As the egg expands, the mycelium ruptures and may remain as a cup at the base of the stalk. The gills of the mushroom produce microscopic spores, which are shot off and fall between the gills, helping the fungus to spread.
Mushrooms are the part of fungi that we can see, as the non-reproductive portions of fungi are hidden underground or within another substrate, such as a log. They are formed when the fungus is ready to reproduce and are where the nuclei of the two mating types of fungi fuse and split into spores. Therefore, mushrooms are the fruiting bodies of fungi, akin to gonadal structures in animals.

Mushrooms don't have seeds
Mushrooms are not fruits, nor are they vegetables. They are fungi, belonging to their own kingdom, Mycota, separate from plants (Plantae) and animals (Animalia). They are not plants because they do not contain chlorophyll, the green pigment that enables plants to make their own food via photosynthesis. Instead, they rely on the nutrition of a plant (live or dead) or an animal to feed.
Mushrooms are the reproductive structures of fungi, often referred to as "fruiting bodies". This is because the word "fruit" refers to analogous structures in botany, and mushrooms are the result of the fungus' hard work. However, mushrooms are not fruits in a botanical or culinary sense.
Mushrooms do not grow like plants, and they do not have seeds. Instead, they reproduce via spores, the product of sexual reproduction. When the fungus is ready to reproduce, it makes a mushroom. On the tips of the gills, the nuclei fuse and split into four spores, and each spore is released and dispersed. This is why mushrooms cannot be bred like plants or animals, although it is possible to breed mushrooms.
Mushrooms start their lives underground as white fluff, which is called mycelium, the fungal threads that sprout the mushrooms. In the wild, mycelium can stay underground for a long time, and when the circumstances are favourable, buds will form and seek daylight, resulting in the birth of a mushroom.

Mushrooms are not vegetables
Mushrooms are typically produced above ground on soil or another food source. They develop from a nodule or pinhead, called a primordium, which is formed within the mycelium, the mass of thread-like hyphae that make up the fungus. The primordium enlarges into a roundish structure called a "button", which has a cottony roll of mycelium, the universal veil, that surrounds the developing fruit body. As the egg expands, the universal veil ruptures and may leave remnants at the base of the stalk or as warts or patches on the cap.
While mushrooms are commonly cooked like vegetables and used as a vegetarian meat substitute, they are not vegetables. Vegetables are edible plants that come from leaves, stems, or roots, whereas mushrooms do not have roots and do not need light to grow. Mushrooms are part of their own kingdom, separate from plants and animals, due to the sheer number of species that exist.
