The Common Earthball (Scleroderma citrinum) is a type of fungus found in various habitats, including forests and grasslands. It typically has a round, ball-like shape and can vary in color from yellowish to brown. This fungus is known for its hard outer shell, which protects the spores inside. When mature, it releases spores through a small opening at the top. Common Earthballs are often mistaken for edible mushrooms, but they are toxic and can cause gastrointestinal distress if ingested. They play an important role in the ecosystem by breaking down organic matter and contributing to soil health. Their presence indicates a healthy environment, making them significant in the study of mycology and ecology.
