Fungus are organisms ranging from yeast, mushroom, molds, and more. It is its own kingdom separate from bacteria, plants, and animals. Fungi have been both useful to mankind as food or helping the process of making food and drink such as wine and bread, to being used in materials such as detergeants. They have also been a problem for mankind, as mold can grow on food or destroy food supplies and crops. They have also been used as the species for fantasy monsters like Myconids.
