 They usually live in soil and many species trap or stun nematodes (nematophagous fungus), while others attack amoebae or collembola.Fungi that grow on the epidermis, hair, skin, nails, scales or feathers of living or dead animals are considered to be dermatophytes rather than carnivores.Similarly, fungi in orifices and the digestive tract of animals are not carnivorous, and neither are internal pathogens.
