Class:Oomycota
Order:Peronosporales
Family:Albuginaceae
Genus:Albugo
White rust pathogens create chlorotic (yellowed) lesions and sometimes galls on the upper leaf surface and there are corresponding white blister-like dispersal pustules of sporangia on the underside of the leaf. Species of the Albuginaceae deform the branches and flower parts of many host species. Host species include most if not all plants in the Brassicaceae family, common agricultural weeds, and those specified below.

Some important features of Albugo have been described below -
Explanation:
- It causes white rust in crucifers as it is a obligate parasitic fungus.
- It feeds by means of haustoria by penetrating the wall of host cells.
- Reproduces asexually by sporangia and these are produced on the club-shaped hyphae called the sporangiophores.
- The zoospores that are produced are are biflagellate, reniform, uninucleate.
- Sexual reproduction is of oogamous type.
- The antheridia and oogonia are produced close to each other at the end of the growing season.
