NOTE: Beneficial fungi to use are listed in order from easiest to obtain to more difficult to obtain.

Many species of beneficial fungi are entomopathogenic (that is, they infect and kill pest insects) making them excellent biopesticides and valuable partners for growers. Other species of beneficial fungi are mycoparasites that attack and kill fungal pathogens that cause disease on your plants. A third valuable feature of some beneficial fungi is that they can symbiotically colonize the root systems of your plants, live as mycorrhizal associates, and protect your plants from fungal pathogens.

All fungi, both beneficial and pathogenic, have a body made of filaments, or hyphae. The living body of the fungus looks like a spiderweb, but it grows through the growing media, leaf, or insect. All fungi reproduce by spores, which are produced both sexually (requiring genetic materials from two individuals) and asexually (a single organism produces an exact copy of itself). When a spore germinates, it produces a hypha, which penetrates the food source. Fungi secrete enzymes that digest their food outside their bodies, and then the fungi absorb the nutrients.
