Dikarya Dikarya is a subkingdom of Fungi that includes the phyla Ascomycota and Basidiomycota, both of which in general produce dikaryons, may be filamentous or unicellular, but are always without flagella. The Dikarya are most of the so called "higher fungi", but also include many anamorphic species that would have been classified as moulds in (inc. Deuteromycota The Fungi imperfecti or imperfect fungi, also known as Deuteromycota are fungi which do not fit into the commonly established taxonomic classifications of fungi that are based on biological species concepts or morphological characteristics of sexual structures because their sexual form of reproduction has never been observed; hence the name ")
- Ascomycota The Ascomycota are a Division/Phylum of the kingdom Fungi, and subkingdom Dikarya. Its members are commonly known as the Sac Fungi. They are the largest phylum of Fungi, with over 64,000 species. The defining feature of this fungal group is the "ascus" (from Greek: ἀσκός , meaning "sac" or "wineskin"), a
- Pezizomycotina Pezizomycotina is a subphylum of the Ascomycota and is more or less synonymous with the older taxon Euascomycota. These fungi reproduce by fission rather than budding and this subdivision includes almost all the ascus fungi which have fruiting bodies visible to the naked eye (exception: genus Neolecta which belongs to the Taphrinomycotina)
- Saccharomycotina Saccharomycotina is a subphylum of the phylum Ascomycota , and consists of yeasts - they form no ascocarps (fruiting bodies), their asci are naked, and they can reproduce asexually by budding
- Taphrinomycotina Taphrinomycotina is one of three subphyla constituting the Ascomycota and is more or less synonymous with the slightly older invalid name Archiascomycetes (sometimes spelled Archaeascomycetes). Recent molecular studies suggest that the group is monophyletic and basal to the rest of the Ascomycota
- Basidiomycota Basidiomycota is one of two large phyla that, together with the Ascomycota, comprise the subkingdom Dikarya (often referred to as the "higher fungi") within the Kingdom Fungi. More specifically the Basidiomycota include mushrooms, puffballs, stinkhorns, bracket fungi, other polypores, jelly fungi, boletes, chanterelles, earth stars,
- Agaricomycotina The subphylum Agaricomycotina, also known as the hymenomycetes, is one of three taxa of the fungal division Basidiomycota . The Agaricomycotina contain some 20,000 species, and about 98% of these are in the class Agaricomycetes: most of the fungi known as mushrooms, including the bracket fungi and puffballs. Species in the Agaricomycotina that are
- Pucciniomycotina
- Ustilaginomycotina Ustilaginomycotina refers to a subphylum within the phylum Basidiomycota of the kingdom Fungi, consisting of the classes Entorrhizomycetes, Ustilaginomycetes, Exobasidiomycetes and the order Malassezia
- Entomophthoromycotina
- Kickxellomycotina Kickxellomycotina is a fungus grouping. The name was changed from "Harpellomycotina", because "Kickxellomycotina" had an older stem

A fungus (pronounced /ˈfʌŋɡəs/) is a member of a large group of eukaryotic A eukaryote is an organism whose cells contain complex structures inside the membranes. The defining membrane-bound structure that sets eukaryotic cells apart from prokaryotic cells is the nucleus, or nuclear envelope, within which the genetic material is carried. The presence of a nucleus gives eukaryotes their name, which comes from the Greek ε organisms that includes microorganisms such as yeasts Yeasts are eukaryotic micro-organisms classified in the kingdom Fungi, with about 1,500 species currently described; they dominate fungal diversity in the oceans. Most reproduce asexually by budding, although a few do so by binary fission. Yeasts are unicellular, although some species with yeast forms may become multicellular through the formation and molds Molds include all species of microscopic fungi that grow in the form of multicellular filaments, called hyphae. In contrast, microscopic fungi that grow as single cells are called yeasts. A connected network of these tubular branching hyphae has multiple, genetically identical nuclei and is considered a single organism, referred to as a colony or, as well as the more familiar mushrooms A mushroom is the fleshy, spore-bearing fruiting body of a fungus, typically produced above ground on soil or on its food source. The standard for the name "mushroom" is the cultivated white button mushroom, Agaricus bisporus, hence the word mushroom is most often applied to those fungi that have a stem (stipe), a cap (pileus), and gills. The Fungi (pronounced /ˈfʌndʒaɪ/ or /ˈfʌŋɡaɪ/) are classified as a kingdom In biological taxonomy, kingdom or regnum is a taxonomic rank in either the highest rank, or (in the new three-domain system) the rank below domain. Each kingdom is divided into smaller groups called phyla (or in some contexts these are called "divisions"). Currently, many textbooks from the United States use a system of six kingdoms ( that is separate from plants Plants are living organisms belonging to the kingdom Plantae. They include familiar organisms such as trees, herbs, bushes, grasses, vines, ferns, mosses, and green algae. The scientific study of plants, known as botany, has identified about 350,000 extant species of plants, defined as seed plants, bryophytes, ferns and fern allies. As of 2004,, animals Animals are a major group of mostly multicellular, eukaryotic organisms of the kingdom Animalia or Metazoa. Their body plan eventually becomes fixed as they develop, although some undergo a process of metamorphosis later on in their life. Most animals are motile, meaning they can move spontaneously and independently. All animals are also and bacteria The bacteria ( [bækˈtɪərɪə] ; singular: bacterium)[α] are a large group of unicellular, prokaryote, microorganisms. Typically a few micrometres in length, bacteria have a wide range of shapes, ranging from spheres to rods and spirals. Bacteria are ubiquitous in every habitat on Earth, growing in soil, acidic hot springs, radioactive waste,. One major difference is that fungal cells have cell walls A cell wall is a tough, usually flexible but sometimes fairly rigid layer that surrounds some types of cells. It is located outside the cell membrane and provides these cells with structural support and protection, and also acts as a filtering mechanism. A major function of the cell wall is to act as a pressure vessel, preventing over-expansion that contain chitin Chitin n (pronounced /ˈkaɪtɨn/) is a long-chain polymer of a N-acetylglucosamine, a derivative of glucose, and is found in many places throughout the natural world. It is the main component of the cell walls of fungi, the exoskeletons of arthropods such as crustaceans (e.g. crabs, lobsters and shrimps) and insects, the radulas of mollusks and, unlike the cell walls of plants, which contain cellulose Cellulose is an organic compound with the formula n, a polysaccharide consisting of a linear chain of several hundred to over ten thousand β(1→4) linked D-glucose units. These and other differences show that the fungi form a single group of related organisms, named the Eumycota (true fungi or Eumycetes), that share a common ancestor In evolutionary biology, a group of organisms have common descent if they have a common ancestor. All living organisms on Earth are descended from a common ancestor or ancestral gene pool (a monophyletic In common cladistic usage, a monophyletic group is a taxon which forms a clade, meaning that it consists of an ancestor and all its descendants. The term is synonymous with the uncommon term holophyly. It is contrasted with the terms paraphyly, which is a taxon consisting of an ancestor and some of its descendants, and polyphyly, which is a taxon group). This fungal group is distinct from the structurally similar slime molds Slime mold is a broad term describing fungus-like organisms that use spores to reproduce. They were formerly classified as fungi, but are no longer considered part of this kingdom (myxomycetes) and water molds Oömycota or oömycetes (pronounced /ˌoʊ əˈmaɪ sit is/), also known as water molds (or water moulds: see spelling differences), form a distinct phylogenetic lineage of fungus-like eukaryotic microorganisms. They are filamentous microscopic, absorptive organisms that reproduce both sexually and asexually. Oomycetes occupy both saprophytic and (oomycetes). The discipline of biology Biology is a natural science concerned with the study of life and living organisms, including their structure, function, growth, origin, evolution, distribution, and taxonomy devoted to the study of fungi is known as mycology Mycology is the branch of biology concerned with the study of fungi, including their genetic and biochemical properties, their taxonomy, and their use to humans as a source for tinder, medicinals (e.g., penicillin), food (e.g., beer, wine, cheese, edible mushrooms), entheogens, as well as their dangers, such as poisoning or infection. From, which is often regarded as a branch of botany Botany, plant science, phytology, or plant biology is a branch of biology and is the scientific study of plant life and development. Botany covers a wide range of scientific disciplines that study plants, algae, and fungi including: structure, growth, reproduction, metabolism, development, diseases, chemical properties, and evolutionary, even though genetic studies have shown that fungi are more closely related to animals than to plants.
Abundant worldwide, most fungi are inconspicuous because of the small size of their structures, and their cryptic In ecology, crypsis is the ability of an organism to avoid observation or detection by other organisms. A form of antipredator adaptation, methods range from camouflage, nocturnality, subterranean lifestyle, transparency, or mimicry. The word can also be used in the context of eggs and pheromone production lifestyles in soil, on dead matter, and as symbionts The term symbiosis commonly describes close and often long-term interactions between different biological species. The term was first used in 1879 by the German mycologist Heinrich Anton de Bary, who defined it as "the living together of unlike organisms." The definition of symbiosis is in flux, and the term has been applied to a wide of plants, animals, or other fungi. They may become noticeable when fruiting In fungi, the sporocarp is a multicellular structure on which spore-producing structures, such as basidia or asci, are born. The fruiting body is part of the sexual phase of a fungal life cycle, with the rest of the life cycle being characterized by vegetative mycelial growth and asexual spore production, either as mushrooms or molds. Fungi perform an essential role in the decomposition of organic matter and have fundamental roles in nutrient cycling In ecology and Earth science, a biogeochemical cycle or nutrient cycle is a pathway by which a chemical element or molecule moves through both biotic and abiotic (lithosphere, atmosphere, and hydrosphere) compartments of Earth. In effect, the element is recycled, although in some cycles there may be places (called reservoirs) where the element is and exchange. They have long been used as a direct source of food, such as mushrooms and truffles A truffle is a fungal fruiting body that develops underground and relies on mycophagy for spore dispersal. Almost all truffles are ectomycorrhizal and are therefore usually found in close association with trees, as a leavening Bread is a staple food prepared by cooking a dough of flour and water and possibly more ingredients. Doughs are usually baked, but in some cuisines breads are steamed, fried, or baked on an unoiled skillet. It may be leavened or unleavened. Salt, fat and leavening agents such as yeast and baking soda are common ingredients, though bread may agent for bread, and in fermentation Fermentation in food processing typically is the conversion of carbohydrates to alcohols and carbon dioxide or organic acids using yeasts, bacteria, or a combination thereof, under anaerobic conditions. A more restricted definition of fermentation is the chemical conversion of sugars into ethanol. The science of fermentation is known as zymology of various food products, such as wine Wine is an alcoholic beverage, typically made of fermented grape juice. The natural chemical balance of grapes is such that they can ferment without the addition of sugars, acids, enzymes or other nutrients. Wine is produced by fermenting crushed grapes using various types of yeast. Yeast consumes the sugars found in the grapes and converts them, beer Beer is the world's oldest and most widely consumed alcoholic beverage and the third most popular drink overall after water and tea. It is produced by the brewing and fermentation of starches, mainly derived from cereal grains—most commonly malted barley, although wheat, maize , and rice are widely used. Most beer is flavoured with hops, which, and soy sauce Soy sauce, or soya sauce, is produced by fermenting soybeans with Aspergillus oryzae and Aspergillus soyae molds along with roasted grain, water, and salt. It is used in traditional East and Southeast Asian cuisines, but also appears in modern Western cuisine and prepared foods. Since the 1940s, fungi have been used for the production of antibiotics In common usage, an antibiotic is a substance or compound that kills, or inhibits the growth of, bacteria. Antibiotics belong to the broader group of antimicrobial compounds, used to treat infections caused by microorganisms, including fungi and protozoa.[citation needed], and, more recently, various enzymes Enzymes are mainly proteins, that catalyze chemical reactions. In enzymatic reactions, the molecules at the beginning of the process are called substrates, and the enzyme converts them into different molecules, called the products. Almost all processes in a biological cell need enzymes to occur at significant rates. Since enzymes are selective for produced by fungi are used industrially Enzymes are mainly proteins, that catalyze chemical reactions. In enzymatic reactions, the molecules at the beginning of the process are called substrates, and the enzyme converts them into different molecules, called the products. Almost all processes in a biological cell need enzymes to occur at significant rates. Since enzymes are selective for and in detergents A protease breaks down proteins. A protease is any enzyme that conducts proteolysis, that is, begins protein catabolism by hydrolysis of the peptide bonds that link amino acids together in the polypeptide chain forming the protein. Proteases work best in acidic conditions. Fungi are also used as biological agents A biological agent is a bacterium, virus, prion, fungus, or biological toxin that can be used in bioterrorism or biological warfare. More than 1200 different kinds of biological agents have been described and studied to date. Applying a slightly broader definition, some eukaryotes and their associated toxins can be considered as biological agents to control weeds and pests. Many species produce bioactive Pharmacological or biological activity is an expression describing the beneficial or adverse effects of a drug on living matter. When the drug is a complex chemical mixture, this activity is exerted by the substance's active ingredient or pharmacophore but can be modified by the other constituents. The main kind of biological activity is a compounds called mycotoxins A mycotoxin (from Greek μύκης "fungus" and Latin (toxicum) "poison") is a toxic secondary metabolite produced by an organism of the fungus kingdom, including mushrooms, molds, and yeasts. The term 'mycotoxin' is usually reserved for the toxic chemical products produced by fungi that readily colonize crops. Most fungi are, such as alkaloids Alkaloids are naturally occurring chemical compounds containing basic nitrogen atoms. The name derives from the word alkaline and is used to describe any nitrogen-containing base and organic compounds with one or more of the following features: a heterocyclic compound containing nitrogen, with an alkaline pH and a marked physiological action on and polyketides Polyketides are secondary metabolites from bacteria, fungi, plants, and animals. Polyketides are usually biosynthesized through the decarboxylative condensation of malonyl-CoA derived extender units in a similar process to fatty acid synthesis . The polyketide chains produced by a minimal polyketide synthase are often further derivitized and, that are toxic to animals including humans. The fruiting structures of a few species contain psychotropic A psychoactive drug, psychopharmaceutical or psychotropic is a chemical substance that acts primarily upon the central nervous system where it alters brain function, resulting in changes in perception, mood, consciousness and behavior. These drugs may be used recreationally to purposefully alter one's consciousness, as entheogens for ritual or compounds and are consumed recreationally or in traditional spiritual ceremonies. Fungi can break down manufactured materials and buildings, and become significant pathogens of humans and other animals. Losses of crops due to fungal diseases (e.g. rice blast disease) or food spoilage can have a large impact on human food supplies and local economies.
The fungus kingdom encompasses an enormous diversity of taxa with varied ecologies, life cycle strategies, and morphologies ranging from single-celled aquatic chytrids to large mushrooms. However, little is known of the true biodiversity of Kingdom Fungi, which has been estimated at around 1.5 million species, with about 5% of these having been formally classified. Ever since the pioneering 18th and 19th century taxonomical works of Carl Linnaeus, Christian Hendrik Persoon, and Elias Magnus Fries, fungi have been classified according to their morphology (e.g., characteristics such as spore color or microscopic features) or physiology. Advances in molecular genetics have opened the way for DNA analysis to be incorporated into taxonomy, which has sometimes challenged the historical groupings based on morphology and other traits. Phylogenetic studies published in the last decade have helped reshape the classification of Kingdom Fungi, which is divided into one subkingdom, seven phyla, and ten subphyla.

A. 'C' 'One of the unusual formations of Basidiomycota are known as fairy rings. Fungi grows on dead leaves and roots in grasslands, and produce rings of fruiting bodies or mushrooms. The rings expand every year and release nitrogen into the soil, creating very lush grass. These rings expand every year. Folkloric legends associated these rings with fairy dances, which is how they got their name. Most do not damage the grass, but some fungi, such as Marasmius oreades (also known as the fairy ring champignon) will kill the areas beneath it. They accomplish this by forming water-repellent masses of hyphae beneath the soil, dehydrating the grass. The fairy ring is not just of interest to scientists or landscapers. Its presence within folkloric… [cont.]
