Toadstools, also known as mushrooms, are a type of fungi. They are typically characterized by their umbrella-like shape and can be found in many different colors and sizes. Toadstools are often found in damp, dark places such as forests and meadows. They are edible, but some species are poisonous and should not be consumed. Toadstools are an important part of the ecosystem, providing food for animals and helping to break down organic matter.
