Entomophthoromycota
The Entomophthoromycota are fungi in which the sporangium has been reduced to function as a single conidium that is forcibly discharged at maturity. If the conidium does not land on a favourable substrate, it in turn produces a second and smaller conidium which is again shot away. Members of the Entomophthoromycota are often parasitic on insects, and other animals and some species have developed very potent proteolytic enzyme systems. Although they are capable of growing saprobically in pure culture, many species require a complex nutrient medium to stimulate sporulation (King 1983). Basidiobolus ranarum, Conidiobolus coronatus and C. incongruus are the only species of the Entomophthoromycota that are known to cause human disease. Conidiobolus lamprauges has also been reported once from a horse (Humber, Brown and Kornegay 1989).
