Phallus rubicundus is a species of fungus in the stinkhorn family. First described in 1811, it has a wide distribution in tropical regions. It has the typical stinkhorn structure consisting of a spongy stalk up to 15 cm (5.9 in) tall arising from a gelatinous "egg" up to 3 cm (1.2 in) in diameter. Atop the stalk is a pitted, conical cap that has a foul-smelling, gelatinous, green spore mass spread over it.

Taxonomy

The species was first described under the name Satyrus rubicundus by French botanist Louis Augustin Guillaume Bosc in 1811,[2] from collections made in South Carolina.[3] It was later transferred to the genus Phallus in 1823 by Elias Fries.[4] Synonyms include binomials resulting from the transfer to Ithyphallus by Eduard Fischer in 1888, and to Leiophallus by Émile-Victor Mussat in 1900.[1]

Description

Bisected "egg" form

Immature (unopened) specimens of Phallus rubicundus are spherical to egg-shaped, whitish, and measure 2–3 cm (0.8–1.2 in) long by 1–3 cm (0.4–1.2 in) wide. They occur singly or in groups of two to six eggs that are formed from a common mycelium.[5] They are attached to the substrate by a cordlike rhizomorph. After expanding, the fruit bodies are up to 15 cm (5.9 in) tall, and consist of a hollow cylindrical stalk supporting a conical to bell-shaped cap. The orange to scarlet stalk tapers towards to top, and has a pitted surface.[6] The wrinkled cap is scarlet red, and measures 2–3 cm (0.8–1.2 in) high by 1–2 cm (0.4–0.8 in) wide. It is initially covered with a foetid, slimy grayish-olive gleba.[6] The egg case remains at the base of the stalk as a volva.[7] The spores are smooth, elliptical, and measure 3.6–4.2 by 1.6–2.0 μm.[6]

Phallus rubicundus is often confused with the similar Mutinus elegans, but the latter species does not have a clearly separated cap, and instead bears its gleba on the apex of its pointed stalk.[3]

Uses

In the Indian state of Madhya Pradesh, where it is known locally as jhiri pihiri, it is used by two primitive forest tribes, the Bharia and the Baiga, as a treatment against typhoid, and also by the Baiga to treat labour pain. The fungus is prepared by grinding and mixing with sugar-cake, and one teaspoon is administered three times daily.[8] The fungus has been reported to have been used by Aboriginal Australians as an aphrodisiac.[9]

One study noted that mosquitoes, attracted to the smell of the gleba, perish after consuming it, and so the fungus may be suitable for further investigating as a biocontrol agent.[10]

Ecology and distribution

The fungus is saprobic, and grows in sandy soils, lawns, gardens, and yards, especially those that are well-manured or use wood mulch. It is widely distributed in southern and eastern United States (including Hawaii[7]), having possibly been spread through the use of imported wood mulch in landscaping.[3] In Australia it grows mainly in the tropics and subtropics, in areas where rotten wood and/or mulch are present.[11] In Asia, it has been recorded from China,[12] Japan,[13] Korea,[14] India,[8] and Thailand.[15] African locales include Ghana, Nigeria,[16] Congo, Kenya,[17] and South Africa.[6] It is also known from South America (Argentina[18] and Brazil[19]) and the Caribbean.[6] The fungus was featured on a Sierra Leonean postage stamp in 1993.[20]
