Urocystis brassicae is a gall smut^[1] and a plant pathogen that stunts the infected plants.^[2] It is known to create root galls on Indian Mustard (Brassica campestris) and other Brassica species.

Physical characteristics

Gall characteristics

The wart-like galls of U. brassicae grow on the roots of plants.^[3]^[4]^[5] When young, the galls are white in color.^[2] As they age, they become a grayish-black colored gall with a 2–5 cm diameter.^[2]

Spore characteristics

Urocystis brassicae has two types of spores.^[4] One is fertile and the other is sterile.^[4] Fertile spores are a deep brown color with dimensions of approximately 20 by 16 μm.^[4] These fertile spores are surrounded by sterile spores that are elongated and a brighter brown than the fertile spores.^[4] These sterile spores are approximately 9.9 by 6.1 μm.^[4]

Distribution of Urocystis brassicae

Urocystis brassicae is commonly found in India (Bihar) ^[6] and China.^[1]
