"Hyaloperonospora parasitica" is a species from the family Peronosporaceae. It has been considered for a long time to cause downy mildew of a variety of species within the Brassicaceae family such as oilseed rape and cauliflower, on which the disease can cause economically important damage by killing seedlings or affecting the quality of produce intended for freezing.

In fact, as a rule "Hyaloperonospora" species are genetically and biologically quite distant from each other. Each species of "Hyaloperonospora" is highly specialized and parasitises only few distinct host species or even only a single one. [Citation

For instance, the taxonomically correct name of the parasite of the well-known model organism "Arabidopsis thaliana" is "Hyaloperonospora arabidopsidis", not "H. parasitica", whereas the pathogen of "Brassica" has to be called "Hyaloperonospora brassicae".
