Taxonomy

Phallus indusiatus was initially described by French naturalist Étienne Pierre Ventenat in 1798,[2] and sanctioned under that name by Christiaan Hendrik Persoon in 1801.[3] One author anonymously gave his impressions of Ventenat's discovery in an 1800 publication:

This beautiful species, which is sufficiently characterised to distinguish it from every other individual of the class, is copiously produced in Dutch Guiana, about 300 paces from the sea, and nearly as far from the left bank of the river of Surinam. It was communicated to me by the elder Vaillant,[N 1] who discovered it in 1755 on some raised ground which was never overflowed by the highest tides, and is formed of a very fine white sand, covered with a thin stratum of earth. The prodigious quantity of individuals of this species which grow at the same time, the very different periods of their expansion, the brilliancy and the varied shades of their colours, present a prospect truly picturesque.[4]

The fungus was later placed in a new genus, Dictyophora, in 1809 by Nicaise Auguste Desvaux;[5] it was then known for many years as Dictyophora indusiata.[6] Christian Gottfried Daniel Nees von Esenbeck placed the species in Hymenophallus in 1817, as H. indusiatus.[7] Both genera were eventually returned to synonyms of Phallus and the species is now known again by its original name.[1][6]

Curtis Gates Lloyd described the variety rochesterensis in 1909, originally as a new species, Phallus rochesterensis. It was found in Kew, Australia.[8] A form with a pink-coloured indusium was reported by Vincenzo de Cesati in 1879 as Hymenophallus roseus, and later called Dictyophora indusiata f. rosea by Yosio Kobayasi in 1965;[9] it is synonymous with Phallus cinnabarinus.[10] A taxon described in 1936 as Dictyophora lutea[11] and variously known for years as Dictyophora indusiata f. lutea, D. indusiata f. aurantiaca, or Phallus indusiatus f. citrinus, was formally transferred to Phallus in 2008 as a distinct species, Phallus luteus.[12]

Etymology

The specific epithet is the Latin adjective indūsǐātus, "wearing an undergarment".[13] The former generic name Dictyophora is derived from the Ancient Greek words δίκτυον (diktyon, "net"), and φέρω (pherō, "to bear"), hence "bearing a net".[5][14] Phallus indusiatus has many common names based on its appearance, including long net stinkhorn, crinoline stinkhorn,[15] basket stinkhorn,[16] bridal veil fungus,[17] and veiled lady. The Japanese name Kinugasatake (衣笠茸 or キヌガサタケ), derived from the word kinugasa, refers to the wide-brimmed hats that featured a hanging silk veil to hide and protect the wearer's face.[18] A Chinese common name that alludes to its typical growth habitat is "bamboo mushroom" (simplified Chinese: 竹荪; traditional Chinese: 竹蓀; pinyin: zhúsūn).[19]

Description

Cooktown, Australia
. The lacy "skirt" under the cap is the indusium.

Immature fruit bodies of P. indusiatus are initially enclosed in an egg-shaped to roughly spherical subterranean structure encased in a

indusium (or less technically a "skirt") that hangs down from the conical to bell-shaped cap. The netlike openings of the indusium may be polygonal or round in shape.[20] Well-developed specimens have an indusium that reaches to the volva and flares out somewhat before collapsing on the stalk.[21] The cap is 1.5–4 cm (1⁄2–1+1⁄2 in) wide and its reticulated (pitted and ridged) surface is covered with a layer of greenish-brown and foul-smelling slime, the gleba, which initially partially obscures the reticulations. The top of the cap has a small hole.[16] The stalk is 7–25 cm (3–10 in) long,[20] and 1.5–3 cm (1⁄2–1+1⁄4 in) thick. The hollow stalk is white, roughly equal in width throughout its length, sometimes curved, and spongy. The ruptured peridium remains as a loose volva at the base of the stalk.[16] Fruit bodies develop during the night,[22] and require 10–15 hours to fully develop after emerging from the peridium.[23] They are short-lived, typically lasting no more than a few days.[22] At that point the slime has usually been removed by insects, leaving the pale off-white, bare cap surface exposed.[20] Spores of P. indusiatus are thin-walled, smooth, elliptical or slightly curved, hyaline (translucent), and measure 2–3 by 1–1.5 μm.[24]

Similar species

Compared to Phallus indusiatus ...
... P. multicolor is smaller and more brightly coloured
... P. luteus is bright yellow

Phallus multicolor is similar in overall appearance, but it has a more brightly coloured cap, stem and indusium, and it is usually smaller. It is found in Australia, Guam, Sumatra, Java, Borneo, Papua New Guinea, Zaire, and Tobago [25] as well as Hawaii. The cap of the Indo-Pacific species P. merulinus appears smooth when covered with gleba, and is pale and wrinkled once the gleba has worn off. In contrast, the cap surface of P. indusiatus tends to have conspicuous reticulations that remain clearly visible under the gleba. Also, the indusium of P. merulinus is more delicate and shorter than that of P. indusiatus, and is thus less likely to collapse under its own weight.[26] Common in eastern North America and Japan, and widely recorded in Europe,[27] the species P. duplicatus has a smaller indusium that hangs 3–6 cm (1+1⁄4–2+1⁄4 in) from the bottom of the cap, and sometimes collapses against the stalk.[28]

Found in Asia, Australia, Hawaii, southern Mexico, and Central and South America,[10] P. cinnabarinus grows to 13 cm (5 in) tall, and has a more offensive odor than P. indusiatus. It attracts flies from the genus Lucilia (family Calliphoridae), rather than the house flies of the genus Musca that visit P. indusiatus.[29] P. echinovolvatus, described from China in 1988, is closely related to P. indusiatus, but can be distinguished by its volva that has a spiky (echinulate) surface, and its higher preferred growth temperature of 30 to 35 °C (86 to 95 °F).[30] P. luteus, originally considered a form of P. indusiatus, has a yellowish reticulate cap, a yellow indusium, and a pale pink to reddish-purple peridium and rhizomorphs. It is found in Asia and Mexico.[12]

Distribution

The range of Phallus indusiatus is

tropical, including Africa (Congo,[21] Nigeria,[31] Uganda,[32] and Zaire[33]) South America (Brazil[24] Guyana,[34] and Venezuela[35]), Central America (Costa Rica),[36] and Tobago.[37] In North America, its range is restricted to Mexico.[38] Asian localities include Indonesia, Nepal, Malaysia,[39] India,[8] Southern China, Japan,[22] and Taiwan.[40] It has also been collected in Australia.[41]

Ecology

Like all Phallus species, P. indusiatus is

stingless bees of the genus Trigona,[44] and flies of the families Drosophilidae and Muscidae. Insects assist in spore dispersal by consuming the gleba and depositing excrement containing intact spores to germinate elsewhere.[22] Although the function of the indusium is not known definitively, it may visually entice insects not otherwise attracted by the odour, and serve as a ladder for crawling insects to reach the gleba.[45]

Uses

The fungus is sold dried and is usually rehydrated before cooking.
Tom yuea phai is a Thai soup made with this fungus.

Culinary

In eastern Asia, P. indusiatus is considered a delicacy and an

diplomatic relations in the early 1970s.[49] One source writes of the mushroom: "It has a fine and tender texture, fragrance and is attractive, beautiful in shape, fresh and crispy in taste."[50] The dried fungus, commonly sold in Asian markets, is prepared by rehydrating and soaking or simmering in water until tender.[51] Sometimes used in stir-frys, it is traditionally used as a component of rich chicken soups.[52] The rehydrated mushroom can also be stuffed and cooked.[53]

Phallus indusiatus has been

relative humidity of 90–95%.[55] Other substrates that can be used for the cultivation of the fungus include bamboo leaves and small stems, soybean pods or stems, corn stems, and willow leaves.[56]

Medicinal

Medicinal properties have been ascribed to Phallus indusiatus from the time of the Chinese

leucorrhea, fever, and oliguria (low urine output), diarrhea, hypertension, cough, hyperlipidemia, and in anticancer therapy.[57]
Modern science has probed the biochemical basis of these putative medicinal benefits.

The fruit bodies of the fungus contain

tumour often used in research) in mice.[59][61]

Chemical structure of Hydroxymethylfurfural
Hydroxymethylfurfural inhibits the enzyme tyrosinase.
Chemical structure of Albaflavenone
Albaflavenone has antibiotic properties.

Another chemical of interest found in P. indusiatus is

browning reactions in damaged fruits during post-harvest handling and processing,[63] and its inhibitors are of interest to the medical, cosmetics, and food industries. Hydroxymethylfurfural, which occurs naturally in several foods, is not associated with serious health risks.[62] P. indusiatus also contains a unique ribonuclease (an enzyme that cuts RNA into smaller components) possessing several biochemical characteristics that differentiate it from other known mushroom ribonucleases.[64]

Two novel

astroglial cells.[65] Related compounds isolated and identified from the fungus include three quinazoline derivatives (a class of compounds rare in nature), dictyoquinazol A, B, and C.[66] These chemicals were shown in laboratory tests to have a protective effect on cultured mouse neurons that had been exposed to neurotoxins.[67] A total synthesis for the dictyoquinazols was reported in 2007.[68]

The fungus has long been recognised to have

sesquiterpenoid that was already known from the soil bacterium Streptomyces albidoflavus.[69] Experiments have shown that extracts of P. indusiatus have antioxidant in addition to antimicrobial properties in chemical assays.[70]

A 2001 publication in the International Journal of Medicinal Mushrooms attempted to determine its efficacy as an aphrodisiac. In the trial involving sixteen women, six self-reported the experience of a mild orgasm while smelling the fruit body, and the other ten, who received smaller doses, self-reported an increased heart rate. All of the twenty men tested considered the smell displeasing. The study used fruit bodies found in Hawaii, not the edible variety cultivated in China.[71] The study has received criticism. A way to achieve instant orgasms would be expected to gain much attention and many attempts to reproduce the effect, but none has succeeded. No major science journal has published the study, and there are no studies where the results have been reproduced.[72][73]

In culture

According to ethnomycologist

charm to make hunters less visible in times of danger. In other parts of Nigeria, they have been used in the preparation of harmful charms by ethnic groups such as the Urhobo and the Ibibio people. The Igbo people of east-central Nigeria called stinkhorns éró ḿma, from the Igbo words for "mushroom" and "beauty".[31]
