A class of imperfect fungi in which the vegetative stage is typically a well-developed mycelium. In some species the sexual states are unknown; others are the conidial states (see conidium) of fungi classified in other (true) subdivisions. There are about 1000 genera. Sometimes the class is considered to contain a single order, sometimes it is not subdivided into orders and families. It includes predatory, parasitic, and saprotrophic fungi, found in aquatic or terrestrial habitats.
