Nematophagous fungus

Nematophagous fungi are carnivorous fungi specialized in trapping and digesting nematodes. Around 160 species are known. There exist both species that live inside the nematodes from the beginning and others that catch them mostly with glue traps or in rings, some of which constrict on contact. Some species possess both types of traps. Another technique is to stun the nematodes using toxins, which is a method employed by Coprinus comatus, Stropharia rugosoannulata, and the family Pleurotaceae.

Nematophagous fungus can be useful in controlling nematodes. Purpureocillium for example can be used as a bio-nematicide.
