Trichomycetes are a cosmopolitan group of fungi and protists that grow obligately in the guts of insects, crustaceans, and millipedes that live in freshwater, marine, or terrestrial habitats. The taxonomy of these organisms is based primarily on morphology of the vegetative thallus; spore type and dimensions; host; and habitat.
