Stink Horn

Species in the Phallaceae are gasteroid—having spores that are produced internally. Fruit bodies originate as a gelatinous, spherical or egg-shaped structure that may be completely or partially buried underground. The peridium, the outer layer of the egg, is white, or purple/red, with two or three layers. The outer layer is thin, membranous and elastic, while the inner layer is thicker, gelatinous and continuous. At maturity the peridium opens up and remains as a volva at the base of the receptaculum.
