[3] Albugo candida has a cosmopolitan distribution and is known from many countries where cruciferous crops are grown in Europe, Asia, Africa, Australasia, North, Central, and South America.

On stems, leaves, and inflorescences it appears as a mass of white or cream-coloured pustules, each about 2 mm (0.08 in) in diameter, packed with sporangia.

[7] The systemic version causes distortion, abnormal growth forms, and sterile inflorescences.

[8] Infection with white rust predisposes a crop to develop downy mildew, caused by another oomycete plant pathogen Phytophthora nicotianae.

[9] When liberated, the sporangia inside the pustules are spread by wind, rain, and insects.

The most recent one, using Pacific Biosciences sequencing technology, produced an genome assembly of 38.96 megabases, with 13,073 predicted genes.
