Fungus

Fungus is a simple, non-vascular organism, often plant-like in appearance but living as a decomposer or parasite. It reproduces via spores and includes yeasts, molds, and more complex mushrooms. In everyday use, it refers to any member of the kingdom Fungi distinct from plants and animals. The term is widely used in biology, medicine, and horticulture to describe organisms with a threadlike mycelium and chitinous cell walls.
