Colus pusillus is a species of fungus in the family Phallaceae. It is found in Australia. [2] It is sometimes known as the craypot stinkhorn or basket stinkhorn, a reference to the unique appearance of the fruiting bodies which consist of vivid red, wrinkled arms that branch and connect to form a cage-like structure reminiscent to that of the related species Clathrus ruber. This fungus is saprobic and makes frequent appearances on garden mulch as a result.

Like all stinkhorns, the fruit body of C. pusillus begins as an egg-like structure. The eggs of C. pusillus are typically off-white, with a red/purple tinge and a faint latticed pattern on the surface. They are anchored to the substrate by one or more root-like rhizomorphs: thickened mycelial strands. The membrane of the "egg" soon ruptures, releasing the rapidly expanding mature receptacle, which can reach a height of around 15 cm. The interior of the cage is covered by an unevenly distributed glebal slime, which contains the fungal spores. This slime is olive-green in colour and has a foul smell, which attracts insects that distribute the fungus' spores to a suitable location.

<span class="mw-page-title-main">Phallaceae</span> Family of fungi

Phallaceae is a family of fungi, commonly known as stinkhorns, within the order Phallales. Stinkhorns 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 Phallales. The spore mass typically smells of carrion or dung, and attracts flies, beetles and other insects to help disperse the spores. Although there is great diversity in body structure shape among the various genera, all species in the Phallaceae begin their development as oval or round structures known as "eggs". The appearance of Phallaceae is often sudden, as gleba can erupt from the underground egg and burst open within an hour. According to a 2008 estimate, the family contains 21 genera and 77 species.

<i>Phallus indusiatus</i> Widespread species of stinkhorn fungus

Phallus indusiatus, commonly called the bamboo mushrooms, bamboo pith, long net stinkhorn, crinoline stinkhorn, bridal veil, or veiled lady, is a fungus in the family Phallaceae, or stinkhorns. It has a cosmopolitan distribution in tropical areas, and is found in southern Asia, Africa, the Americas, and Australia, where it grows in woodlands and gardens in rich soil and well-rotted woody material. The fruit body of the fungus is characterised by a conical to bell-shaped cap on a stalk and a delicate lacy "skirt", or indusium, that hangs from beneath the cap and reaches nearly to the ground. First described scientifically in 1798 by French botanist Étienne Pierre Ventenat, the species has often been referred to a separate genus Dictyophora along with other Phallus species featuring an indusium. P. indusiatus can be distinguished from other similar species by differences in distribution, size, color, and indusium length.

<i>Phallus impudicus</i> Fungus known as the common stinkhorn

Phallus impudicus, known colloquially as the common stinkhorn, is a widespread fungus in the Phallaceae (stinkhorn) family. It is recognizable for its foul odor and its phallic shape when mature, the latter feature giving rise to several names in 17th-century England. It is a common mushroom in Europe and North America, where it occurs in habitats rich in wood debris such as forests and mulched gardens. It appears from summer to late autumn. The fruiting structure is tall and white with a slimy, dark olive colored conical head. Known as the gleba, this material contains the spores, and is transported by insects which are attracted by the odor—described as resembling carrion. Despite its foul smell, it is not usually poisonous and immature mushrooms are consumed in parts of France, Germany and the Czech Republic.

<i>Phallus ravenelii</i> Stinkhorn fungus from North America

Phallus ravenelii, commonly known as Ravenel's stinkhorn, is a fungus in the Phallaceae (stinkhorn) family. It is found in eastern North America. Its mushrooms commonly grow in large clusters and are noted for their foul odor and phallic shape when mature. It is saprobic, and as such it is encountered in a wide variety of habitats rich in wood debris, from forests to mulched gardens or sawdust piles in urban areas. It appears from August to October. The fruit body emerges from a pink or lavender-colored egg to form a tall, cylindrical, hollow and spongy white stalk with a bell-shaped cap. The remains of the egg persist as a white to pink or lilac volva at the base of the stalk. The cap is covered in a foul-smelling olive-green spore slime, which attracts insects that help to spread the spores. Sometimes, the cap has a "veil" attached—a thin membrane that hangs underneath. The lack of a roughly ridged and pitted cap differentiates it from the closely related Phallus impudicus. The fungus is named after Henry William Ravenel, a botanist who first discovered it in 1846, though it remained undescribed until 1873. It is considered to be an edible mushroom while in its egg form.

<i>Aseroe rubra</i> Species of fungus

Aseroe rubra, commonly known as the anemone stinkhorn, sea anemone fungus and starfish fungus, is a common and widespread basidiomycete fungus recognizable for its foul odour of carrion and its sea anemone shape when mature. Found in gardens on mulch and in grassy areas, it resembles a red star-shaped structure covered in brownish slime on a white stalk. It attracts flies, which spread its spores.

<i>Phallus duplicatus</i> Netted stinkhorn or wood witch fungus

Phallus duplicatus is a species of fungus in the stinkhorn family. The bell-shaped to oval cap is green-brown, the cylindrical stalk is white. When mature the cap becomes sticky with a slimy green coating that attracts flies that disperse its spores, and it has a distinct, "netted" universal veil. The fungus is edible when still in the "egg" stage, before the fruit body has expanded. It grows often in public lawns, and can also be found in meadows.

<i>Phallus hadriani</i> Dune stinkhorn or sand stinkhorn fungus

Phallus hadriani, commonly known as the dune stinkhorn or the sand stinkhorn, is a species of fungus in the Phallaceae (stinkhorn) family. It is a widely distributed species, and is native to Asia, Europe, and North America. In Australia, it is probably an introduced species. The stalk of the fruit body reaches up to 20 cm (7.9 in) tall by 4 cm (1.6 in) thick, and is spongy, fragile, and hollow. At the top of the stem is a ridged and pitted, thimble-like cap over which is spread olive-colored spore slime (gleba). Shortly after emerging, the gleba liquefies and releases a fetid odor that attracts insects, which help disperse the spores. Said to be edible in its immature egg-like stage, it typically grows in public lawns, yards and gardens, usually in sandy soils. Phallus hadriani may be distinguished from the similar P. impudicus by the presence of a pink or violet-colored volva at the base of the stem, and by differences in odor.

<i>Mutinus caninus</i> Species of fungus

Mutinus caninus, commonly known as the dog stinkhorn, is a small thin, phallus-shaped woodland fungus, with a dark tip. It is often found growing in small groups on wood debris, or in leaf litter, during summer and autumn in Europe, Asia, and eastern North America. It is not generally considered edible, although there are reports of the immature 'eggs' being consumed.

<i>Clathrus archeri</i> Species of fungus

Clathrus archeri, commonly known as octopus stinkhorn or devil's fingers, is a fungus which has a global distribution. This species was first described in 1980 in a collection from Tasmania. The young fungus erupts from a suberumpent egg by forming into four to seven elongated slender arms initially erect and attached at the top. The arms then unfold to reveal a pinkish-red interior covered with a dark-olive spore-containing gleba. In maturity it smells like putrid flesh. Recently, C. archeri var. alba with white tentacles or arms has been reported from the Shola Forests in the Western Ghats, Kerala, India.

<i>Clathrus ruber</i> Species of fungus in the stinkhorn family

Clathrus ruber is a species of fungus in the family Phallaceae, and the type species of the genus Clathrus. It is commonly known as the latticed stinkhorn, the basket stinkhorn, or the red cage, alluding to the striking fruit bodies that are shaped somewhat like a round or oval hollow sphere with interlaced or latticed branches. The fungus is saprobic, feeding off decaying woody plant material, and is often found alone or in groups in leaf litter on garden soil, grassy places, or on woodchip garden mulches. Although considered primarily a European species, C. ruber has been introduced to other areas, and now has a wide distribution that includes all continents except Antarctica. The species was illustrated in the scientific literature during the 16th century, but was not officially described until 1729.

<i>Lysurus periphragmoides</i> Species of fungus

Lysurus periphragmoides, commonly known as the stalked lattice stinkhorn or chambered stinkhorn, is a species of fungus in the stinkhorn family. It was originally described as Simblum periphragmoides in 1831, and has been known as many different names before being transferred to Lysurus in 1980. The saprobic fungus has a pantropical distribution, and has been found in Africa, Asia, Australasia, and the Americas, where it grows on fertile ground and on mulch. The fruit body, which can extend up to 15 cm (5.9 in) tall, consists of a reddish latticed head placed on top of a long stalk. A dark olive-green spore mass, the gleba, fills the interior of the lattice and extends outwards between the arms. Like other members of the family Phallaceae, the gleba has a fetid odor that attracts flies and other insects to help disperse its spores. The immature "egg" form of the fungus is considered edible.

<i>Ileodictyon</i> Genus of fungi

Ileodictyon is a genus of fungi in the family Phallaceae. Basidiocarps are clathroid, emerging from egg-like peridia and forming spongy "arms" which connect to create a cage-like lattice. The basidiospores on the arms are covered by a foetid slime that attracts flies, the agents of spore dispersal. There are two named species and one currently unnamed. The unnamed species, called "the green cage fungus", is endemic to New Caledonia and is considered globally threatened. It is assessed as "endangered" on The IUCN Red List of Threatened Species.

<i>Pseudocolus fusiformis</i> Species of fungus

Pseudocolus fusiformis is a stinkhorn mushroom in the Phallaceae, a family well known for a remarkable range of fruit body types. It is the most widely distributed member of the genus Pseudocolus and has been found in the United States, Australia, Japan, Java, and the Philippines. It is commonly known as the stinky squid, because of its fetid odor, and its three or four upright "arms" which are connected at the top. The malodorous smell comes from the dark greenish slimy gleba covering the inside faces of the arms, and attracts insects that help to disperse the spores.

<i>Clathrus columnatus</i> Species of fungus

Clathrus columnatus, commonly known as the column stinkhorn, is a saprobic species of basidiomycete fungus in the family Phallaceae. It has a widespread distribution, and has been found in Africa, Australasia, and the Americas. It may have been introduced to North America with exotic plants. Similar to other stinkhorn fungi, the fruiting body, known as the receptaculum, starts out as a subterranean "egg" form. As the fungus develops, the receptaculum expands and erupts out of the protective volva, ultimately developing into mature structures characterized by two to five long vertical orange or red spongy columns, joined at the apex. The fully grown receptaculum reaches heights of 8 cm (3.1 in) tall. The inside surfaces of the columns are covered with a fetid olive-brown spore-containing slime, which attracts flies and other insects that help disseminate the spores. Although once considered undesirable, the fungus is listed as edible. It is found commonly in mulch.

<i>Mutinus elegans</i> Species of stinkhorn fungus

Mutinus elegans, commonly known as the elegant stinkhorn, the dog stinkhorn, the headless stinkhorn, or the devil's dipstick, is a species of fungus in the Phallaceae (stinkhorn) family. A saprobic species, it is typically found growing on the ground singly or in small groups on woody debris or leaf litter, during summer and autumn in Japan, Europe, and eastern North America. The fruit body begins its development in an "egg" form, resembling somewhat a puffball partially submerged in the ground. As the fungus matures, a slender orange to pink colored stalk emerges that tapers evenly to a pointed tip. The stalk is covered with a foul-smelling slimy green spore mass on the upper third of its length. Flies and other insects feed upon the slime which contains the spores, assisting in their dispersal. Due to their repellent odor, mature specimens are not generally considered edible, although there are reports of the immature "eggs" being consumed. In the laboratory, Mutinus elegans has been shown to inhibit the growth of several microorganisms that can be pathogenic to humans.

<span class="mw-page-title-main">Gasteroid fungi</span> Group of fungi

The gasteroid fungi are a group of fungi in the Basidiomycota. Species were formerly placed in the obsolete class Gasteromycetes Fr., or the equally obsolete order Gasteromycetales Rea, because they produce spores inside their basidiocarps rather than on an outer surface. However, the class is polyphyletic, as such species—which include puffballs, earthstars, stinkhorns, and false truffles—are not closely related to each other. Because they are often studied as a group, it has been convenient to retain the informal (non-taxonomic) name of "gasteroid fungi".

<i>Aseroe coccinea</i> Species of fungus

Aseroe coccinea is a species of stinkhorn fungus in the genus Aseroe. First reported in Japan in 1989, it was not formally validated as a species until 2007, the delay related to a publication error. The receptacle, or fruit body, begins as a partially buried whitish egg-shaped structure, which bursts open as a hollow white stipe with reddish arms, then erupts and grows to a height of up to 15 mm (0.6 in). It matures into a star-shaped structure with seven to nine thin reddish tubular "arms" up to 10 mm (0.4 in) long radiating from the central area. The top of the receptacle is covered with dark olive-brown spore-slime, or gleba. A. coccinea can be distinguished from the more common species A. rubra by differences in the color of the receptacle, and in the structure of the arms. The edibility of the fungus has not been reported.

<i>Staheliomyces</i> Genus of fungi

Staheliomyces is a fungal genus in the stinkhorn family. The genus was considered monotypic for over 100 years, containing the single neotropical species Staheliomyces cinctus, until a 2022 study revealed four additional, cryptic species. Members are colloquially known as the strangled stinkhorns. The genus is found in Central America and northern South America. The fruit body of the fungus is a hollow, whitish, cylindric stalk up to 16 cm (6.3 in) tall, with conspicuous pits and holes. Near the top of the stalk is a pinched-off zone covered with unpleasant-smelling slimy spore mass called gleba. The gleba attracts stingless bees that help disseminate the spores.

<i>Aseroe floriformis</i> Species of fungus

Aseroe floriformis is a species of fungus in the stinkhorn family Phallaceae. Described as a new species in 2005, it is known only from northeast Brazil, where it grows on sandy soil. The fruit body has a raspberry-colored stipe, and, unlike other members of the genus Aseroe does not have radiating branches.

<i>Colus hirudinosus</i> Species of fungus

Colus hirudinosus is a species of stinkhorn fungus (Gasteromycete) found in Asia, Australia, northern Africa, and southern Europe. The fruit body has a short, thick stalk that divides into several spongy, wrinkled, stalk-like, orange to red columns that are united at the top, thus forming a lattice. The spores are found within the gleba—a dark, olive-brown slime that coats the inside of the columns. Spores are spread by insects that are attracted by the fetid smell of the gleba, eat the spores, and pass them on to germinate elsewhere.
