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, including as a source for tinder, traditional medicine, food, and entheogens, as well as their dangers, such as toxicity or infection.
Genus is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus.
Ruminants are hoofed herbivorous grazing or browsing mammals that are able to acquire nutrients from plant-based food by fermenting it in a specialized stomach prior to digestion, principally through microbial actions. The process, which takes place in the front part of the digestive system and therefore is called foregut fermentation, typically requires the fermented ingesta to be regurgitated and chewed again. The process of rechewing the cud to further break down plant matter and stimulate digestion is called rumination. The word "ruminant" comes from the Latin ruminare, which means "to chew over again".
A unicellular organism, also known as a single-celled organism, is an organism that consists of a single cell, unlike a multicellular organism that consists of multiple cells. Organisms fall into two general categories: prokaryotic organisms and eukaryotic organisms. All prokaryotes are unicellular and are classified into bacteria and archaea. Many eukaryotes are multicellular, but some are unicellular such as protozoa, unicellular algae, and unicellular fungi. Unicellular organisms are thought to be the oldest form of life, with early protocells possibly emerging 3.8–4.0 billion years ago.
Obligate anaerobes are microorganisms killed by normal atmospheric concentrations of oxygen (20.95% O2). Oxygen tolerance varies between species, with some species capable of surviving in up to 8% oxygen, while others lose viability in environments with an oxygen concentration greater than 0.5%.
The rumen, also known as a paunch, is the largest stomach compartment in ruminants and the larger part of the reticulorumen, which is the first chamber in the alimentary canal of ruminant animals. The rumen's microbial favoring environment allows it to serve as the primary site for microbial fermentation of ingested feed. The smaller part of the reticulorumen is the reticulum, which is fully continuous with the rumen, but differs from it with regard to the texture of its lining.
Polioencephalomalacia (PEM), also referred to as cerebrocortical necrosis (CCN), is a neurological disease seen in ruminants that is caused by multiple factors, one of which is thiamine depletion in the body. Thiamine is a key chemical in glucose metabolism that, when deficient, is most threatening to neurological activity. In addition to altered thiamine status, an association with high sulfur intake has been observed as a potential cause of PEM. Other toxic or metabolic diseases can result in PEM as well. Cattle, sheep, goat, and other ruminants that are diagnosed with PEM or pre-PEM suffer opisthotonus, cortical blindness, disoriented movement, and eventually fatality, if left untreated. Current data shows that the onset of PEM can range from birth to late adulthood.
Neocallimastigomycota is a phylum containing anaerobic fungi, which are symbionts found in the digestive tracts of larger herbivores. Anaerobic fungi were originally placed within phylum Chytridiomycota, within Order Neocallimastigales but later raised to phylum level, a decision upheld by later phylogenetic reconstructions. It encompasses only one family.
The Gomphales are an order of basidiomycete fungi. Some or all families belonging to Gomphales have been sometimes included in the order Phallales, the now-obsolete Ramariaceae was also previously included in Cantharellales. Recent phylogenetic analyses include in Gomphales the families of the original description of the order by Walter Jülich, with addition of Clavariadelphaceae. According to one 2008 estimate, the Gomphales contain 18 genera and 336 species.
The Basidiobolaceae are a family of fungi in the order Entomophthorales. All fungal cells of this family are exclusively uninucleate and their relatively large nuclei contain a nucleolus, but no heterochromatin.
A cannulated cow or fistulated cow refers to a cow that has been surgically fitted with a cannula. A cannula acts as a porthole-like device that allows access to the rumen of a cow, to perform research and analysis of the digestive system and to allow veterinarians to transplant rumen contents from one cow to another.
Anaeromyces is a genus of fungi in the family Neocallimastigaceae.
Orpinomyces is a genus of fungi in the family Neocallimastigaceae.
Enteridium lycoperdon, the false puffball, is one of the more obvious species of slime mould or Myxogastria, typically seen in its reproductive phase as a white 'swelling' on standing dead trees in the spring, or on large pieces of fallen wood. Alder is a common host.
Neocallimastix patriciarum is a species of fungus that lives in the rumen of sheep and other ruminant species. N. patriciarum is an obligate anaerobe and is an important component of the microbial population within the rumen. Only one of a few rumen fungi, this species is interesting and unique within the fungal world. Originally thought to be a flagellate protists, species within the phylum Neocallimastigomycota were first recognized as a fungi by Colin Orpin in 1975 when he demonstrated that they had cell walls of chitin
Acetitomaculum ruminis is a Gram-positive bacterium species from the genus of Acetitomaculum which has been isolated from the rumen of a bovine in the United States. Acetitomaculum ruminis utilize formate, glucose and CO2.
Buwchfawromyces is a genus of anaerobic fungi isolated from buffalo faeces
Rumen Georgiev Radev is a Bulgarian politician and former major general who is the current president of Bulgaria since 22 January 2017.

Anaeromyces robustus is a fungal microorganism that lives in the gut rumen of many different large herbivores such as cows and sheep. Previously thought to be protozoa from their flagellated zoospores, they are biomass degraders and help the animal by breaking down carbohydrates and plant materials from the food the animal ingests. This fungus, therefore, is anaerobic and lives without oxygen. Gut fungi are dramatically outnumbered by other organisms in the microbiome, however, they are very important members of the gut microbiome in ruminants and hind-gut fermenters.
