Mushrooms in many ways
A mushroom is the fleshy, spore-bearing fruiting body of a fungus, typically produced above ground on soil or on its food source.
“Mushroom” describes a variety of gilled fungi, with or without stems, and the term is used even more generally, to describe both the fleshy fruiting bodies of some Ascomycota and the woody or leathery fruiting bodies of some Basidiomycota, depending upon the context of the word.
The terms “mushroom” and “toadstool” go back centuries and were never precisely defined, nor was there consensus on application. The term “toadstool” was often, but not exclusively, applied to poisonous mushrooms or to those that have the classic umbrella-like cap-and-stem form.
In German folklore and old fairy tales, toads are often depicted sitting on toadstool mushrooms and catching, with their tongues, the flies that are said to be drawn to the Fliegenpilz, a German name for the toadstool, meaning “flies’ mushroom”. This is how the mushroom got another of its names, Krötenstuhl, literally translating to “toad-stool”.
