The Oomycetes

  • Ervin H. Barnes


The Oomycetes typically produce oospores, nonseptate or coenocytic hyphae, and sporangia. The sporangia may germinate by the production and liberation of zoospores with two flagella or they may germinate by the production of a germ tube. Zoospores are generally produced at lower temperatures than the germ tubes. Since zoospores are biflagellate and swim, moist conditions generally favor their dissemination. The sporangia, on the other hand, are deciduous and are disseminated by wind and splashing rain.
