In as much as they are touted as being harmful to human health once they grow on food, most of them are in fact edible, and a good example can be observed through mushrooms. A mushroom, if it by any chance happens to be your favorite food, is a good example of fungi in its fruiting stage. The fungi have since time immemorial been used as leavening agents for bread, fermentation of some food products such as wine and beer and industrially in the production of antibiotics. Some of the enzymes found in humicula sp are used in the manufacture of detergents.

Agriculturally, they have been known to be used as weed and pest control agents. Their cell wall is composed of chitin, as earlier mentioned, and glucans. They are the only known organisms that combine the two structural molecules in their cell walls. Funny enough, glucans are also found in plants while chitin is normally found in the exoskeleton of arthropods. Since humicula sp lack an elaborate system through which water and nutrients are transported, they will form some biological structures that resemble and perform functions similar to those performed by roots of plants.

Most fungi will grow in a varied range of habitats, including some with extreme conditions such as deserts or areas with high salt concentration. It is common to find some having grown in deep-sea sediments. The ones living in water always find their way into some of their amphibian hosts since they live in a zoosphere, which helps them propel themselves in water. The fungal kingdom has been estimated to contain about one million species, which have over the years been distinguished over a variety of methods and concepts. Most fungi tend to assume the hyphae form when growing and they as such appear as threadlike, cylindrical structures. These are adapted to their environments in such a way that they ensure complete absorption of water and relevant nutrients.
