(mycology)

Entomophthorales

 

an order of fungi of the class Phyco-mycetes. The mycelium is reduced and frequently divided into irregular shaped sections called hyphal bodies. During fusion the bodies form zygospores or divide by means of budding. Some cells form conidiophores, each of which carries one conidium. A characteristic feature of the Entomophthorales is their ability to throw off ripe conidia with considerable force and for great distances. Entomophthorales can be parasites of insects, protozoans, and nematodes. Some live as saprophytes on dead insect tissue.

The order embraces approximately 150 species, belonging to 28 genera. They are found throughout the world.
