Branch of biology concerned with the study of fungi

Mycology is the branch of biology concerned with the study of fungi, including their taxonomy, genetics, biochemical properties, and use by humans. Fungi can be a source of tinder, food, traditional medicine, as well as entheogens, poison, and infection. Mycology branches into the field of phytopathology, the study of plant diseases. The two disciplines are closely related, because the vast majority of plant pathogens are fungi. A biologist specializing in mycology is called a mycologist.

Although mycology was historically considered a branch of botany, the 1969 discovery of fungi's close evolutionary relationship to animals resulted in the study's reclassification as an independent field. Pioneer mycologists included Elias Magnus Fries, Christian Hendrik Persoon, Anton de Bary, Elizabeth Eaton Morse, and Lewis David von Schweinitz. Beatrix Potter, author of The Tale of Peter Rabbit, also made significant contributions to the field. Pier Andrea Saccardo developed a system for classifying the imperfect fungi by spore color and form, which became the primary system used before classification by DNA analysis. He is most famous for his Sylloge Fungorum, which was a comprehensive list of all of the names that had been used for mushrooms. Sylloge is still the only work of this kind that was both comprehensive for the botanical kingdom Fungi and reasonably modern. Many fungi produce toxins, antibiotics, and other secondary metabolites. For example, the cosmopolitan genus Fusarium and their toxins associated with fatal outbreaks of alimentary toxic aleukia in humans were extensively studied by Abraham Joffe. Fungi are fundamental for life on earth in their roles as symbionts, e. g. in the form of mycorrhizae, insect symbionts, and lichens. Many fungi are able to break down complex organic biomolecules such as lignin, the more durable component of wood, and pollutants such as xenobiotics, petroleum, and polycyclic aromatic hydrocarbons. By decomposing these molecules, fungi play a critical role in the global carbon cycle. Fungi and other organisms traditionally recognized as fungi, such as oomycetes and myxomycetes (slime molds), often are economically and socially important, as some cause diseases of animals (including humans) and of plants. Apart from pathogenic fungi, many fungal species are very important in controlling the plant diseases caused by different pathogens. For example, species of the filamentous fungal genus Trichoderma are considered one of the most important biological control agents as an alternative to chemical based products for effective crop diseases management. Some fungi can cause disease in humans and other animals; the study of pathogenic fungi that infect animals is referred to as medical mycology.

It is believed that humans started collecting mushrooms as food in prehistoric times. Mushrooms were first written about in the works of Euripides (480–406 BC). The Greek philosopher Theophrastos of Eresos (371–288 BC) was perhaps the first to try to systematically classify plants; mushrooms were considered to be plants missing certain organs. It was later Pliny the Elder (23–79 AD), who wrote about truffles in his encyclopedia Natural History. The word mycology comes from the Ancient Greek: μύκης (mukēs), meaning "fungus" and the suffix [[wikt: λογία ( logia), meaning "study". The Middle Ages saw little advancement in the body of knowledge about fungi. However, the invention of the printing press allowed authors to dispel superstitions and misconceptions about the fungi that had been perpetuated by the classical authors. The start of the modern age of mycology begins with Pier Antonio Micheli's 1737 publication of Nova plantarum genera. Published in Florence, this seminal work laid the foundations for the systematic classification of grasses, mosses and fungi. He originated the still current genus names Polyporus

For centuries, certain mushrooms have been documented as a folk medicine in China, Japan, and Russia. Penicillin, ciclosporin, griseofulvin, cephalosporin and psilocybin are examples of drugs that have been isolated from molds or other fungi.
