Entomophthora Fresenii. 4 to 7. Development of zygospore from two hyphal bodies. (1 to 3 X 145; 4 to 7 X 290; after Thaxter, 1888.) The other species of Entomphthora show essentially the same charac- ters as E. Muscae. For hypnospores they form both zygospores and azygospores. In E. Fresenii, two hyphal bodies change into gametangia and copulate (Fig. 75, 4 and 7), whereby the junction swells to a zygospore.
