Corn Smut: From Field Curiosity to Gourmet Delight
If you’ve grown corn, you’ve probably noticed lumps forming inside the ears. Many post pictures online asking, “Is my corn okay?” The answer is yes—your corn is perfectly fine.
These lumps are called corn smut, a naturally occurring fungus that swells kernels into lumpy growths. They’re not poisonous, chemical-related, or harmful. In fact, corn smut is considered a delicacy in parts of the world.
What Is Corn Smut?
Corn smut, scientifically known as Ustilago maydis, attacks corn plants and transforms smooth kernels into irregular, swollen, pale gray or whitish lumps. As it matures, it turns black or charcoal-colored.
The fungus can also produce blisters on the tassel or stalk. Its defining feature? The dramatic change from normal kernels to lumpy, blistered growths.
Unlike most molds, Ustilago maydis thrives in various conditions. Its life cycle fascinates scientists and gardeners alike.
