Pythiaceae is a family of water moulds. The family includes plant pathogenic fungus-like organisms in the genus Phytophthora; as well as serious plant and animal pathogens in the genus Pythium. The family was circumscribed by German mycologist Joseph Schröter in 1893.

Contents

Lifecycle

  • Live on land (terrestrial), and in water (aquatic), and a combination of the two, (amphibious)
  • Live as deadly parasites, causing some serious plant and animal diseases when terrestrial.
  • The diploid (2N) life stage predominates, with a short haplophase initiated during sexual reproduction as well as asexual reproduction (homothallism predominates in the Family) to fuse gametes.

    • 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).
