The classification is based on the spore case.
Phycomycetes – These are obligate parasites found in moist and damp places or decaying woods. Example – Rhizopus
Ascomycetes – They are also called as sac fungi. They can be coprophilous, decomposers, parasitic or saprophytic. Example – Aspergillus
Basidiomycetes – Mushrooms are the most commonly found basidiomycetes and mostly live as parasites. Example- Agaricus
Deuteromycetes – They are otherwise called imperfect fungi as they do not follow the regular reproduction cycle as the other fungi. Example – Trichoderma.

1) Zygomycota: The fungal group Zygomycota is most frequently encountered as common bread molds, although both freshwater and marine species exist. Most of these live on decaying plant and animal matter found on the substrate. Aquatic species are primarily found in sediments or on algae, but some species are also free floating. A few are found attached to aquatic animals or on decaying leaves. Some are parasites of plants, insects, or small soil animals, while others cause serious infections in humans and domestic animals.
2)Ascomycota: The Ascomycota comprise about 30,000 described species, among them most of the blue-green, red, and brown molds that cause food spoilage, including the salmon-colored bread mold. Ascomycetes are the causes of a number of serious plant diseases, like Dutch elm disease, but the group also includes edible morels and truffles. This group is also comprised of the yeasts used in the production of beer, wine and bread.
3)Basidiomycota: The fungal group Basidiomycota, also known as the club fungi, includes some of the most familiar fungi. Within this group of 16,000 species are the mushrooms, toadstools, shelf fungi, and puffballs. Basidiomycetes play a key role in the environment as decomposes of plant litter. They are distinguished from other fungi by their production of basidiospores, which are borne outside a club-shaped, spore-producing structure called a basidium. This group is poorly represented in the aquatic environment.
4)Deuteromycota: The Deuteromycota, or conidial fungi, are a group of about 17,000 distinct species in which the sexual reproductive features are either not known or are not used to classify them. Their lack of sexual stages was the basis for them being called fungi imperfecti in the past. The term fungi imperfecti was misleading because these fungi are abundant and flourishing. Most Deuteromycota have only asexual reproduction as the sexual stage of the life cycle has been lost or has yet to be discovered. There are a great number of human uses for these fungi; most significant is the production of antibiotics for medicinal use.
