Urocystis primulae is a fungal plant pathogen that infects several species of Primula.[1]
The fungus affects the flowers of the plant, turning the contents of the ovary into a mass of spore balls: clumps of ustilospores wrapped in a layer of sterile cells.[1] It also produces white, powdery conidia in the anthers.[2]
