In fungi, "individuals" typically refers to the visible fruiting bodies or mushrooms that develop from a common mycelium which, although spread over a large area, is otherwise hidden in the soil.
A number of herbaceous flowering plants form clonal colonies via horizontal surface stems termed stolons, or runners; e.g. strawberry and many grasses.
