Huitlacoche, (aka cuitlacoche, corn smut, corn fungus, devil’s corn, and Mexican truffle) is a fungus that infects ears of corn and replaces their kernels with similarly sized black nodes. Long considered a blight by American corn growers, it is prized as a delicacy in Mexico. Huitlacoche has a flavor similar to some mushrooms, tasting earthy with a hint of smokiness.
Note: Cuitlacoche should not be consumed by women who are pregnant.
