Sort the following fungi based on whether they are decomposers, mutualists, or parasites.

Decomposers  are organisms that break down dead or decaying organisms and thus they carry out the natural process of decomposition. In this case examples are; Fungi in association with a fallen log, A fungi association with a dead rabbit, Coprophilous fungi.
Mutualist  is the way two organisms of different species exist in a relationship in which each individual benefits from the activity of the other. In this case examples are; Mycorrhizal fungi on tree roots, fungi in the family Lepiotaceae.
Parasitism is a relationship between species , where organism, the parasite, lives on or in another organism, the host causing it some harm, and is adapted structurally to this way of life. Examples in this case includes; Trichophyton spp, Cryphonectria parasitica, Cordyceps spp, Septobasidiu spp. and an individual scale insect infeted by fungal hyphae.
