Fungi that form adhesive spores (or conidia)
As they move through soil pores, nematodes may encounter these conidia. Some of the fungi are host specific and their conidia will adhere to and infect only a few species of nematode. Although they can be cultured on media, in the soil these fungi are obligate parasites of nematodes and other invertebrates.
