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