Mushrooms are a type of fungus, which are eukaryotic microorganisms. Fungi are distinct from plants and animals and include other microorganisms such as yeasts and molds. Fungi are heterotrophs, meaning they acquire food by absorbing dissolved molecules. They do not photosynthesize and instead grow to move. Mushrooms are the conspicuous umbrella-shaped fruiting bodies of certain fungi, typically of the order Agaricales. Fungi have been used by humans for thousands of years, both as food sources and for medicinal purposes.

What You'll Learn
Mushrooms are fungi, a type of microorganism
Fungi do not photosynthesize and instead grow to move around, except for spores, which may travel through the air or water. Some fungi, including mushrooms, form conspicuous fruit bodies that sometimes resemble plants. Mushrooms are typically of the order Agaricales in the phylum Basidiomycota, and they are often distinguished by their umbrella-shaped sporophores.
Fungi have been used by humans for thousands ofyears, with evidence of their use as tinder, medicine, and food sources found in ancient records and archaeological discoveries. Fungi are also known to produce compounds that are used in modern medicine, such as antibiotics, statins, and psilocybin, which is being investigated for therapeutic use.
While the term "microbe" typically refers to microscopic organisms, some fungi, like the honey fungus, are visible and form vast underground networks that can stretch for miles. Despite this variation in size, fungi are generally considered microorganisms due to their microscopic features and their inclusion in the eukaryotic kingdom alongside other microorganisms.

Fungi are eukaryotic organisms
Mushrooms are considered microorganisms because they are classified as fungi, which are eukaryotic organisms that include microorganisms such as yeasts and molds. Fungi are now considered a separate kingdom, distinct from plants and animals, and have been for around one billion years. Fungi differ from plants and animals in several ways, including their unique cell wall composition and their method of acquiring food.
Fungi, including mushrooms, are eukaryotic organisms. Eukaryotic organisms are defined by the presence of membrane-bound nucleus within their cells, which contains DNA material. Fungi cells contain membrane-bound nuclei with chromosomes that contain DNA with noncoding regions called introns and coding regions called exons. Fungi are unusual among eukaryotes in that their cell walls contain chitin, a biopolymer, in addition to glucans and other typical components.
The fungal cell wall is made of a chitin-glucan complex, with glucans also found in plants and chitin in the exoskeleton of arthropods. Fungi are the only organisms that combine these two structural molecules in their cell walls. Fungi lack an efficient system for the long-distance transport of water and nutrients, unlike plants. To overcome this limitation, some fungi, such as Armillaria, form rhizomorphs, which are similar to plant roots in form and function.
Fungi, including mushrooms, are heterotrophs, meaning they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize; instead, they grow and spread through this process of absorbing molecules. Fungi can occur as yeasts, molds, or a combination of both forms, and most are saprophytes, meaning they live off of decaying matter, while some are parasites, living off of living matter.
Yeasts are eukaryotic microorganisms classified as members of the fungus kingdom, with around 1,500 species currently identified. They are single-celled forms that reproduce by budding, and some are dimorphic, meaning they can also produce filament-like structures called hyphae, similar to molds, under certain culture conditions. Molds, on the other hand, are multinucleated, filamentous fungi composed of hyphae, and they reproduce primarily through asexual reproductive spores.

Fungi are immobile and grow in soil
Fungi are microorganisms that include yeasts, moulds, and mushrooms. They are neither plants nor animals but form their own kingdom. Fungi are eukaryotes, meaning that their cells have a nucleus where DNA is stored. They are heterotrophs, meaning they acquire their food by absorbing dissolved molecules by secreting digestive enzymes into their environment. They do not photosynthesize and rely on growth for mobility.
Fungi are immobile and often grow in soil. They are multi-celled organisms that grow rapidly and extensively in soil, allowing them to bridge gaps and transport nutrients to plants. They prefer slightly acidic, undisturbed soils with low disturbance and stable organic residues with high carbon-to-nitrogen ratios. Their growth in soil is associated with other soil microorganisms, and they compete aggressively for scarce nutrients.
Fungi in soil can be pathogenic, causing agricultural root diseases, or beneficial, helping control diseases and predators. They can also form a mutualistic relationship with plants, such as mycorrhizae, which grow within the root cells of grasses, crops, vegetables, and shrubs.
Fungi in potting soil are common, and sterilizing the soil can prevent their growth. However, sterilization kills all living organisms in the soil, including beneficial microorganisms. Fungi in potting soil can be removed by scooping them out, sterilizing the soil and pot, washing the plant roots, and repotting.
Mushrooms, a type of fungus, form conspicuous fruit bodies that sometimes resemble plants. They have a stem (called a stipe) and a cap. They can grow in potted plants, compost, and forest soil.

Fungi have been used by humans for thousands of years
Fungi are eukaryotic microorganisms that include yeasts and molds, as well as mushrooms. Fungi are neither plants nor animals, but they form a separate kingdom distinct from both plants and animals. They have been used by humans for thousands of years, and their use by humans dates back to prehistory. Ötzi the Iceman, a 5,300-year-old mummified man found in the Austrian Alps, carried two species of polypore mushrooms, which may have been used as tinder or for medicinal purposes. Ancient peoples have also used fungi as a food source, often unknowingly, in the preparation of leavened bread and fermented juices.
Fungi have played a significant role in human evolution and the development of life on Earth. They have helped plants colonize terrestrial environments and have contributed to the survival of early human gatherings by reducing the risk of infection from contaminated liquids through fermentation. Civilizations have been built around bread and beer, which are made with the help of a single fungus. Additionally, the discovery of penicillin from the fungus Penicillium has helped combat bacterial epidemics.
Fungi are also a source of antibiotics, enzymes, and biological pesticides. They produce molecules that humans cannot yet reproduce in a lab, and they possess unique chemical properties that make them valuable in medicine and industry. For example, the bread mold Neurospora crassa has been used by researchers to make several pivotal discoveries in biology.
Furthermore, fungi play an essential role in the decomposition of organic matter and nutrient cycling in the environment. They are also involved in the fermentation of various food products, such as wine, beer, and soy sauce. Fungi have a long history of use in food preparation, preservation, and medicinal purposes. They have been classified according to their morphology and physiology, and while they were once considered members of the plant kingdom, they are now recognized as a distinct kingdom.

Fungi can cause disease
Mushrooms are considered microorganisms because fungi, which include mushrooms, are classified as eukaryotic microorganisms. Fungi are distinct from plants and animals and have unique characteristics that separate them from other kingdoms. Fungi can be yeasts, molds, or a combination of both. They spread by growing or sending reproductive spores into the air or environment.
Fungal infections on the skin can appear red, swollen, or bumpy and may look like a rash. Nail infections can cause discoloration, thickening, or cracking of the nails. In the mouth or throat, fungal infections can cause a white coating or patches. Subcutaneous fungal infections, which occur under the surface of the skin, are often caused by a fungus entering a cut or wound and are more common in tropical and subtropical areas. Examples include sporotrichosis, chromoblastomycosis, and eumycetoma.
Deep fungal infections can affect the lungs, blood, urinary tract, or brain. Some specific types of fungal infections include histoplasmosis, coccidioidomycosis (Valley fever), blastomycosis, aspergillosis, and talaromycosis. These infections are more likely to occur in individuals with weakened immune systems.
Fungi can gain access to host tissues through traumatic implantation or inhalation. The severity of the disease caused by fungi depends on various factors, including the size of the inoculum, the magnitude of tissue destruction, the ability of the fungi to multiply in tissues, and the immunologic status of the host. While most fungal diseases are accidental, some fungi have developed mechanisms to facilitate their multiplication within the host.
