Fungus
A fungus (plural: fungi) is a living organism that includes yeasts, molds, mushrooms and others. Fungi have thin thread-like cells called hyphae that absorb nutrients and anchor the fungus in place. Some, such as mushrooms, also have a body containing many cells. Fungi lack chlorophyll to capture energy from sunlight unlike plants. Instead, they derive nourishments by digesting and absorbing dead organic matter around them. The study of fungi is known as  mycology.
