What Is Corn Fungus: A Guide to Understanding Ustilago maydis
What Is Corn Fungus?
Corn fungus, also known as corn smut or Mexican truffle, is a type of fungus called Ustilago maydis that grows on corn plants and their non-domesticated ancestor.
It is considered a delicacy in Mexico and is gaining popularity outside of the country.
Corn smut is edible and highly nutritious, containing more protein and an additional amino acid (lysine) that regular corn lacks.
It causes small swellings and whitish-gray irregular kernels on the corn, which can grow up to 4-5 inches in diameter before turning black and releasing spores.
It is more prevalent in hot and dry weather followed by heavy rainfall.
While there are no fungicides to prevent corn smut, crop rotation and integrated pest management methods can help control its spread.

- Despite its popularity, corn smut can be considered a crop disease in the agricultural industry, as it reduces the quality and yield of corn crops.
Fascinating facts about corn smut:
- Corn smut can be found in other countries besides Mexico, such as the United States and Japan.
- The development of corn smut is not fully understood and is influenced by factors such as humidity and temperature.
- Research is being conducted to explore the potential health benefits of corn smut, including its antimicrobial and antitumor properties.
To summarize, corn smut is a unique and flavorful fungus that has made its mark in Mexican cuisine. With its nutritional value, economic significance, and historical roots, corn smut continues to captivate both chefs and food enthusiasts alike.
Ustilago Maydis: The Fungus Behind Corn Smut
Corn smut is caused by the fungus Ustilago maydis, which specifically affects corn plants and their non-domesticated ancestor. This unique fungus has a complex life cycle that includes both a saprophytic stage, where it gains energy from decaying organic material, and an invasive stage, where it takes control of its host plants.
During the invasive stage, Ustilago maydis infects the corn plants, leading to substantial economic losses for farmers who are unable to sell the corn smut-infected plants.
To summarize:
- Corn smut is caused by the fungus Ustilago maydis
- It affects corn plants and their non-domesticated ancestor
- Ustilago maydis has a complex life cycle involving both a saprophytic stage and an invasive stage
- The invasive stage leads to economic losses for farmers
“Corn smut can have detrimental effects on corn crops, causing significant economic losses for farmers who cannot sell the infected plants.”
Nutritional Value And Unique Properties Of Corn Smut
One of the most intriguing aspects of corn smut is its edible and highly nutritious nature. It contains more protein and essential amino acids, such as lysine, which regular corn lacks. This makes corn smut not only a culinary delight but also a valuable source of nutrients. Additionally, corn smut has a unique flavor profile, described as earthy, smoky, and slightly sweet, making it a sought-after ingredient in various dishes.
Economic Impact And Symptoms Of Corn Smut
Corn smut, although valued in the culinary world, presents significant challenges for farmers. The economic losses incurred due to infected crops are substantial as these plants are rendered unsellable. Recognizing the symptoms of corn smut is crucial. These include small swellings and whitish-gray irregular kernels that can grow up to 4-5 inches in diameter. Eventually, the galls turn black before bursting open and releasing spores.
Prevention And Cultivation Methods For Corn Smut
Unfortunately, there are currently no fungicides available to prevent corn smut. However, there are several methods that farmers can employ to minimize its impact.
- Crop rotation and Integrated Pest Management (IPM) practices can help reduce the prevalence of corn smut.
- Additionally, cultivating huitlacoche, the delicate corn smut delicacy, can be achieved through artificial inoculation.
- Harvesting of naturally occurring or cultivated galls should be done when they are young and immature, as they are highly perishable.
- It is important to note that leaf galls should not be consumed.
corn smut, or Ustilago maydis, is an intriguing fungus that has become a culinary delicacy in Mexico and beyond. Its unique nutritional properties, coupled with its distinct flavor profile, have made it a sought-after ingredient. However, corn smut also poses challenges to farmers due to its economic impact. While prevention methods are limited, cultivation techniques can be employed to increase production. Understanding the intricacies of corn smut enables us to appreciate the hidden beauty in the world of fungi.

Frequently Asked Questions
What is fungus corn?
Fungus corn, also known as huitlacoche or corn smut, is an intriguing phenomenon that occurs when a fungus grows on organic corn that hasn’t been treated with fungicide. This unique fungus, resembling a Mexican truffle, appears randomly on the corn ears during the ripening process following the rainy season or a sudden rainstorm. Despite its rarity, huitlacoche has gained attention for its distinct flavor and culinary uses, making it a fascinating natural occurrence that adds a touch of intrigue to the world of corn.
Is corn fungus safe to eat?
A: Yes, corn fungus, specifically immature corn smut galls caused by Ustilago maydis, are safe to eat and are even considered a delicacy. However, it is important to note that other types of galls, such as leaf galls, should not be consumed. Therefore, while corn smut can be a unique and tasty addition to certain dishes, caution should be exercised when consuming any type of fungus.
What is fungal infection of corn?
A fungal infection of corn, known as corn smut, is a disease that leads to the formation of galls on various parts of the corn plant, including the ears, leaves, stalks, and tassels. Although corn smut is not commonly found in Utah and is not a significant concern for grain production, it can still affect the overall health and productivity of the crop in affected regions. Farmers and agricultural experts should remain aware of this fungal infection and take appropriate measures to prevent and control its spread to maintain the optimal growth and yield of corn crops.
What are the benefits of corn fungus?
Corn fungus, also known as huitlacoche, offers unique benefits due to its metabolic effects on the corn plant. Huitlacoche boasts nutritional properties distinct from corn, as it contains significantly more protein and is a rich source of lysine, an essential amino acid. Unlike other amino acids, lysine cannot be produced by our bodies, necessitating its intake through our diet. The presence of lysine in huitlacoche adds to its appeal as a valuable dietary supplement, offering enhanced nutritional content and potential health advantages compared to corn.
