 Phallus, commonly known as stinkhorns, are a group of basidiomycetes which produce a foul-scented, phallic mushroom
Mushroom
A mushroom is the fleshy, spore-bearing fruiting body of a fungus, typically produced above ground on soil or on its food source. The standard for the name "mushroom" is the cultivated white button mushroom, Agaricus bisporus; hence the word "mushroom" is most often applied to those fungi that...

History and taxonomy

The genus was first mentioned in the literature by the Dutch botanist Hadrianus Junius

 on the Phallus in Hollandia, describing a mushroom in the form of a penis. He was not convinced that the organism was fungal in nature:
... I am not sure that our Phallus falls within the class of the fungi. I will not definitely decide to place it there because I do not want to make a judgment before others who know more about the matter. The lightness, however, and looseness of the substance and (a necessary condition for the existence of sponges) the sour sap of the moist earth where it was born, all bear witness that it belongs to the family of the fungi. However, the folds and creases, which do not exist here, but do among fungi, bear witness against it. There is also no trace of the cap that is normally connected to the stalk. Here the hat takes the place of the cap, and it can be removed without damage. Moreover, the site where it lives also argues against it, because this plant can only be found in dunes, and only there where old marram grass grows. Fungi, on the other hand, as stated clearly by authors, live in swampy, dirty, and rotting moist places, such as close to the roots of oak trees.


In 1753, Carl Linnaeus used the genus name Phallus in his Species Plantarum
Species Plantarum
Species Plantarum was first published in 1753, as a two-volume work by Carl Linnaeus. Its prime importance is perhaps that it is the primary starting point of plant nomenclature as it exists today. This means that the first names to be considered validly published in botany are those that appear...
