Phallaceae

The Phallaceae are a family of fungi, commonly known as stinkhorn mushrooms. Belonging to the fungal order Phallales, the Phallaceae have a worldwide distribution, but are especially prevalent in tropical regions. They are known for their foul-smelling, sticky spore masses, or gleba, borne on the end of a stalk called the receptaculum. The characteristic fruiting-body structure, a single, unbranched receptaculum with an externally attached gleba on the upper part, distinguishes the Phallaceae from other families in the Phalalles. The spore mass typically smells of carrion or dung, and attracts flies and other insects to help disperse the spores. Although a great diversity of body structure shape exists between the various genera, all species in the Phallaceae begin their development as oval or round structures known as "eggs". According to a 2008 estimate, the family contains 21 genera and 77 species.

Description

Species in the Phallaceae are gasteroid —having 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.
