Corn smut

Ustilago maydis

Description:

Corn disease, it's considered a delicacy in México. Although it can infect any part of the plant, it usually enters the ovaries and replaces the normal kernels of the cobs with large, distorted tumors analogous to mushrooms. These tumors, are made up of much-enlarged cells of the infected plant, fungal threads, and blue-black spores. The spores give the cob a burned, scorched appearance.
