Genera

Pythiaceae is a family of oomycetes. The family includes serious plant and animal pathogens in the genus Pythium. The family was circumscribed by German mycologist Joseph Schröter in 1893.

Lifecycle

Reproduction

The sporangia may germinate via a germ tube or by release of motile zoospores, depending on the species and the environmental conditions.

Economic importance

Some Pythium species cause "damping off" diseases in young plants (seedlings).
