👉 In the context of plant biology, a mycetoma is a type of fungus that is characterized by its ability to form clumps or mats on the surface of plants. Mycetomas are often associated with fungal diseases in the plant and can cause damage to the plant's leaves, stems, and roots. They are also known for their ability to produce toxins that can be harmful to humans who come into contact with them, especially those with weakened immune systems or allergies.
