Synonyms: Aecidium candidum, Albugo capparidis, Albugo cruciferarum, Albugo macrospora, Albugo mauginii, Cystopus candidus, Uredo candida, Uredo cruciferarum.

Common name: white rust of crucifers.

Extract from Wikipedia article: Albugo candida, commonly known as white rust, is a species of oomycete in the family Albuginaceae. It is sometimes called a fungus, but in fact forms part of a distinct lineage of fungus-like microorganisms, Oomycetes, commonly known as water moulds. A. candida is an obligate plant pathogen that infects Brassicaceae species and causes the disease known as white rust or white blister rust. It has a relatively smaller genome than other oomycetes.

Belarusian: Цыстопус белы, Egyptian Arabic: كانديدا البوجو, Welsh: Pothelli gwynion bresych.
