Peronosporaceae
Peronosporaceae are a family of water moulds that contains 21 genera, comprising more than 600 species. Most of them are called downy mildews.

Peronospora
Peronospora is a genus of downy mildews that are obligate plant pathogens. They can cause severe damage to many different cultivated crops, as well as wild and ornamental plants. Peronospora is most closely related to Pseudoperonospora, and together they form the clade of downy mildews with coloured conidia. Peronospora has far more species than any other genus of the downy mildews. However, many species have been moved from this genus to other genera based on phylogenetic evidence. Among these are the species now in Hyaloperonospora, important pathogens of the Brassicaceae. Now, the Peronospo
Pythiaceae
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.
Plasmopara
Plasmopara is a genus of Oomycota. Plasmopara species are plant pathogens, causing downy mildew on carrot, parsley, parsnip, chervil, and impatiens.

Pseudoperonospora
Pseudoperonospora is a genus of water moulds which includes several species known for causing downy mildew infections on plants.
Bremia lactucae
species of fungus-like eukaryotic microorganisms
Hyaloperonospora
Hyaloperonospora is a genus of oomycete, obligate, plant pathogens that was originally considered to be part of Peronospora. Species in this group produce a disease called downy mildew and can infect many important crops. From the 19 downy mildew producing genera, Hyaloperonospora has been grouped with Perofascia in the brassicolous downy mildews. In the group of downy mildews, Hyaloperonospora is the third biggest genus. The most famous species in the genus is the Hyaloperonospora parasitica, or also known as Hyaloperonospora arabidopsis. This species has become a model organism from its abil
