DNA Barcoding Fungi

Fungi are one the largest and most diverse groups of organisms in the world. As we have the plant and animal kingdoms, fungi make up a kingdom of their own. From just talking a look at them, you would probably assume that fungi and plants are very similar, when in fact fungi are actually biologically closer to animals.

Fungi are responsible for important environmental processes such as nutrient cycling and plant, animal and soil health. Humans also rely on fungi in food production, including items such as cheese, bread and chocolate and the manufacture of drugs and biofuels. Not forgetting that there is a huge market for edible mushrooms all over the world.

Mycology is the study of fungi. For something that is so important to ecosystems and biodiversity, fungi are under-studied when compared with animals and plants. There are estimated to be at least six times as many species of fungi than plants, anywhere between 2 and 11 million! Approximately only 150,000 of these have been officially described or recognised.

The criteria used by taxonomists to describe fungal species can make it very difficult to describe, identify and compare across the many different groups. More recently, fungi identification has advanced with the help of DNA barcoding.
