Toadstools are a type of mushroom that are often characterized by their bright colors and umbrella-like shape. They belong to the larger group of fungi and can be found in various environments, including forests and grasslands. While some toadstools are edible, many are toxic and can cause illness if consumed. The term "toadstool" is commonly used to refer to mushrooms that are not safe to eat. Unlike edible mushrooms, which are often cultivated for food, toadstools can be harmful due to the presence of poisonous compounds. It is important to identify them correctly, as some edible mushrooms can resemble toxic varieties, such as Amanita muscaria and Agaricus bisporus.
