Microfungi are organisms such as mold and mildew as well as rust, which cause plant diseases. They grow in plants, soil, water, insects, cow rumen, hair, and skin. The mycelia of microfungi produce thousands of tiny spores that are carried by the air, spreading the fungus. Most of the fungal body consists of microscopic threads extending through the substrate in which it grows; these threads are called hyphae. It has been suggested that Toxic mold be merged into this article or section. ... Mildew is a grey, mold-like growth caused by one of two different types of micro-organisms. ...

The rumen, also known as the fardingbag or paunch forms the larger part of the reticulorumen, which is the first chamber in the alimentary canal of ruminant animals. ... Mycelium is the vegetative part of a fungus consisting of a mass of branching threadlike hyphae that exists below the ground or within another substrate. ... A hypha (plural hyphae) is a long, branching filament that, with other hyphae, forms the feeding thallus of a fungus called the mycelium. ...

Harmful microfungi

Yeast of the species, Sacharomyces cerevisiae

Microfungi can also be harmful, causing the irritating human affliction known as athlete's foot as well as disastrous diseases of crops and trees. The potato famine in Ireland during the mid- to late 1800's was caused by a fungus called Phytophthora infestans that rotted the potato crops for several years.

Diversity

Within the United States, approximately 13,000 species of microfungi on plants or plant products, are thought to exist. Specimens of microfungi are housed in the U.S. National Fungus Collections and other institutions that serve as reservoirs of information and documentation about our nation's natural heritage. By comparing the species reported in the literature with those represented in the collections, one can estimate the number of microfungi known in the United States at 29,000 species. In areas of the world where fungi have been well studied, the ratio of vascular plants to fungi is about 6 to 1, suggesting that there may actually be 120,000 species of fungi within the United States.^[1] Divisions Non-seed-bearing plants Equisetophyta Lycopodiophyta Psilotophyta Pteridophyta Superdivision Spermatophyta Pinophyta Cycadophyta Ginkgophyta Gnetophyta Magnoliophyta The vascular plants are plants in the Kingdom Plantae (also called Viridiplantae) that have specialized tissues for conducting water. ...
