A genus of cellular slime moulds; D. discoideum has been studied particularly as a model differentiation system. In this species, the slug-like pseudoplasmodium varies in size (e.g. 0.5–2.0 mm in length), and the fruiting body consists of a mass of spores borne at the tip of an unbranched, tapering stalk. There are many species, found in soil, dung, decomposing vegetation, etc.
