Not sure I have ever seen an ear of corn that looked like this before, but apparently while it might look quite scary it's actually considered a delicacy for some here in Minnesota. Have you ever heard of a corn truffle before? Corn truffle, corn smut, or as it's known in Mexico, huitlacoche corn is where certain kernels of corn are affected by a fungus and grow into these outrageous sizes, shapes, and colors on the cob. According to the Wisconsin Extension service, corn smut is "caused by the fungus Ustilago maydis, which can survive for several years as spores in soil and corn residue." With the warm and at-times humid conditions we have had over the last month, I wonder if corn farmers will start to see common corn smut in their fields this season?
