Stinkhorn

Species of stinkhorns have gasteroid, or internally produced spores. 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.[4]
