views updated

Oomycota (water mould, downy mildews) Fungus-like organisms in which the zoospores have two flagella, one of the whiplash type and one of the tinsel type. The cell walls of oomycetes are atypical of fungi in that in most species they contain cellulose but not chitin. The majority of species are aquatic, but some are important pathogens of terrestrial plants. The class contains 4 orders.
