Mushrooms are a type of fungi that grow in various environments, often found in soil, decaying wood, or on plants. They come in many shapes, sizes, and colors, with some being edible and others toxic. The part of the mushroom we typically see is called the fruiting body, which produces spores for reproduction. Mushrooms play an essential role in ecosystems by breaking down organic matter and recycling nutrients back into the soil. They are also used in cooking for their unique flavors and textures, with popular varieties including button mushrooms, shiitake, and portobello.
