Durianella is a fungal genus in the suborder Boletineae, family Boletaceae of the order Boletales. [2] It contains the single species Durianella echinulata, found in Peninsular Malaysia and Borneo. [3]
The fungus was originally collected in a jungle in Kemaman, Trengganu (Malaysia), on 24 June 1932, where it was found growing on soil buried in leaves at a river's edge. It was described as Hydnangium echinulatum by E.J.H. Corner and Lilian Hawker in 1953, although they noted that no other known species of Hydnangium had a spiny peridium. [4] The species was known only from a single specimen until recollected in 2005 and 2006. Genetic analysis suggested it was a member of the Boletales suborder Boletineae, and not related to the genus Hydnangium of the Agaricales. The blue-staining suggested a relationship with Gyroporus , while the structure of the fruit bodies suggested an affinity with Pisolithus . [3]
The genus name Durianella refers to the fruit bodies' resemblance to a small durian. [3]
The fungus's fruit bodies are irregular and globular, measuring 1.7–3.5 cm (0.67–1.38 in) wide and 1.2–2.3 cm (0.47–0.91 in) high, and are covered in 1 mm-high tan conical warts. Under the surface is a white 1–2 mm thick peridium which turns dark blue when cut – the superficial 0.5–1 mm doing so immediately, while the remainder takes 1–2 minutes to do so. [3] The gelatinous gleba is in globules throughout the interior and also stains blue when cut. It is white when young and becomes tinted with orange with age. The white fibrous tissue surrounding the gleba lobules also turns blue on cutting. The fruit body has a well-developed columnella (a sterile column of tissue extending from the base of the gleba into the fruit body). It is egg-shaped, gelatinous, measuring 5–15 mm thick by 5–10 mm long. When injured, it stains grayish blue in 1–2 minutes. On the exterior of the fruit body, it is attached to the soil by orange rhizomorphs. [3]
The spores are spherical or nearly so, and have a thick wall measuring 0.5–1.5 μm. The spore surface is covered with narrow spines up to 3 μm long; spore dimensions are 9–10 by 8.5–10 um (without spines) or 12–15 by 11.5–13.5 μm (with spines). The basidia (spore-bearing cells) are club-shaped, measuring 24–32 by 9–11.5 μm, and have two or four sterigmata up to 13 μm long. Clamp connections are absent from the hyphae. [3]
Durianella echinulata is found under trees of the genus Shorea in Peninsular Malaysia and Borneo. It fruits on the ground singly, scattered, or in small clusters. [3]
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.
The Sclerodermataceae are a family of fungi in the order Boletales, containing several genera of unusual fungi that little resemble boletes. Taxa, which include species commonly known as the ‘hard-skinned puffballs’, ‘earthballs’, or 'earthstars', are widespread in both temperate and tropical regions. The best known members include the earthball Scleroderma citrinum, the dye fungus Pisolithus tinctorius and the 'prettymouths' of the genus Calostoma.
Scleroderma is a genus of fungi, commonly known as earth balls, now known to belong to the Boletales order, in suborder Sclerodermatineae. The best known species are S. citrinum and S. verrucosum. They are found worldwide. Various members of this genus are used as inoculation symbionts to colonize and promote the growth of tree seedlings in nurseries. They are not edible.
Calvatia craniiformis, commonly known as the brain puffball or the skull-shaped puffball, is a species of puffball fungus in the family Agaricaceae. It is found in Asia, Australia, and North America, where it grows on the ground in open woods. Its name, derived from the same Latin root as cranium, alludes to its resemblance to an animal's brain. The skull-shaped fruit body is 8–20 cm (3–8 in) broad by 6–20 cm (2–8 in) tall and white to tan. Initially smooth, the skin (peridium) develops wrinkles and folds as it matures, cracking and flaking with age. The peridium eventually sloughs away, exposing a powdery yellow-brown to greenish-yellow spore mass. The puffball is edible when the gleba is still white and firm, before it matures to become yellow-brown and powdery. Mature specimens have been used in the traditional or folk medicines of China, Japan, and the Ojibwe as a hemostatic or wound dressing agent. Several bioactive compounds have been isolated and identified from the brain puffball.
Calostoma is a genus of 29 species of gasteroid fungi in the suborder Sclerodermatineae. Like other gasteroid fungi, Calostoma do not have the spore discharge mechanism associated with typical gilled fungi (ballistospory), and instead have enclosed spore-bearing structures. Resembling round puffballs with raised, brightly colored spore openings (ostioles), elevated on a thick, gelatinous stalks, species have been collected in regions of deciduous, temperate, tropical or subtropical forests. Their distribution includes eastern North America, Central America, Asia, and Australasia. The common name given to some species, "prettymouth", alludes to the brightly colored raised openings (ostioles) that may somewhat resemble lips. Other common names include "hotlips" and "puffball in aspic".
Limnoperdon is a fungal genus in the monotypic family Limnoperdaceae. The genus is also monotypic, as it contains a single species, the aquatic fungus Limnoperdon incarnatum. The species, described as new to science in 1976, produces fruit bodies that lack specialized structures such as a stem, cap and gills common in mushrooms. Rather, the fruit bodies—described as aquatic or floating puffballs—are small balls of loosely interwoven hyphae. The balls float on the surface of the water above submerged twigs. Experimental observations on the development of the fruit body, based on the growth on the fungus in pure culture, suggest that a thin strand of mycelium tethers the ball above water while it matures. Fruit bodies start out as a tuft of hyphae, then become cup-shaped, and eventually enclose around a single chamber that contains reddish spores. Initially discovered in a marsh in the state of Washington, the fungus has since been collected in Japan, South Africa, and Canada.
Calbovista is a fungal genus containing the single species Calbovista subsculpta, commonly known as the sculptured puffball, sculptured giant puffball, and warted giant puffball. It is a common puffball of the Rocky Mountains and Pacific Coast ranges of western North America. The puffball is more or less round with a diameter of up to 15 cm (6 in), white becoming brownish in age, and covered with shallow pyramid-shaped plates or scales. It fruits singly or in groups along roads and in open woods at high elevations, from summer to autumn.
Gymnogaster is a genus of fungi in the family Boletaceae. It is a monotypic genus, containing the single secotioid species Gymnogaster boletoides, found in Australia. The fungus produces bright yellow fruit bodies with a light brown internal gleba, and the fruit bodies turn blue then dark brown after bruising or handling.
Agaricus deserticola, commonly known as the gasteroid agaricus, is a species of fungus in the family Agaricaceae. Found only in southwestern and western North America, A. deserticola is adapted for growth in dry or semi-arid habitats. The fruit bodies are secotioid, meaning the spores are not forcibly discharged, and the cap does not fully expand. Unlike other Agaricus species, A. deserticola does not develop true gills, but rather a convoluted and networked system of spore-producing tissue called a gleba. When the partial veil breaks or pulls away from the stem or the cap splits radially, the blackish-brown gleba is exposed, which allows the spores to be dispersed.
Spongiforma thailandica is a species of fungus in the family Boletaceae, genus Spongiforma. The stemless sponge-like species, first described in 2009, was found in Khao Yai National Park in central Thailand, where it grows in soil in old-growth forests. The rubbery fruit body, which has a strong odor of coal-tar similar to Tricholoma sulphureum, consists of numerous internal cavities lined with spore-producing tissue. Phylogenetic analysis suggests the species is closely related to the Boletaceae genera Porphyrellus and Strobilomyces.
Strobilomyces foveatus is a little-known species of fungus in the family Boletaceae. It was first reported by mycologist E.J.H. Corner in 1972, from specimens he collected in Malaysia in 1959, and has since been found in Australia. Fruit bodies are characterized by the small dark brown to black conical scales covering the cap, and the net-like pattern of ridges on the upper stem. The roughly spherical spores measure about eight micrometres, and are densely covered with slender conical spines. The edibility of this species is unknown.
Spongiforma is a genus of sponge-like fungi in the family Boletaceae. Newly described in 2009, the genus contains two species: S. thailandica and S. squarepantsii. The type species S. thailandica is known only from Khao Yai National Park in central Thailand, where it grows in soil in old-growth forests dominated by dipterocarp trees. The rubbery fruit bodies, which has a strong odour of coal-tar similar to Tricholoma sulphureum, consists of numerous internal cavities lined with spore-producing tissue. S. squarepantsii, described as new to science in 2011, is found in Malaysia. It produces sponge-like, rubbery orange fruit bodies with a fruity or musky odour. These fruit bodies will—like a sponge—resume their original shape if water is squeezed out. The origin of the specific name derives from its perceived resemblance to the cartoon character SpongeBob SquarePants. Apart from differences in distribution, S. squarepantsii differs from S. thailandica in its colour, odour, and spore structure.
Spongiforma squarepantsii is a species of fungus in the family Boletaceae, genus Spongiforma. Found in Malaysia, it was described as new to science in 2011. It produces sponge-like, rubbery orange fruit bodies that have a fruity or musky odour. The fruit bodies reach dimensions of 10 cm (3.9 in) wide by 7 cm (2.8 in) tall. Like a sponge, they will resume their original shape if water is squeezed out. The spores, produced on the surfaces of the hollows of the sponge, are almond-shaped with rough surfaces, and measure 10‑12.5 μm by 6‑7 μm. The name of the fungus derives from the Nickelodeon cartoon character SpongeBob SquarePants from the show of the same name. S. squarepantsii is one of two species in Spongiforma; it differs from S. thailandica in its color, odour, and spore structure.
Tuber oregonense, commonly known as the Oregon white truffle, is a species of edible truffle in the genus Tuber. Described as new to science in 2010, the North American species is found on the western coast of the United States, from northern California to southern British Columbia west of the Cascade Range. A mycorrhizal fungus, it grows in a symbiotic association with Douglas fir. It overlaps in distribution with the closely related T. gibbosum, but they have different growing seasons: T. oregonense typically appears from October through March, while T. gibbosum grows from January to June. The fruit bodies of the fungus are roughly spherical to irregular in shape, and resemble small potatoes up to 5 cm (2 in) in diameter. Inside the truffle is the gleba, which is initially white before it becomes a marbled tan color. The large, often thick-walled, and strongly ornamented spores are produced in large spherical asci. The truffle is highly prized for its taste and aroma. Some individuals have claimed success in cultivating the truffles in Christmas tree farms.
Kalapuya brunnea is a species of truffle in the monotypic fungal genus Kalapuya. The truffle occurs only in the Pacific Northwest region of the United States, in western Oregon and northern California. Known locally as the Oregon brown truffle, it was formerly thought to be an undescribed species of Leucangium until molecular analysis demonstrated that it was distinct from that genus. The truffle is reddish brown with a rough and warty outer skin, while the interior spore-producing gleba is initially whitish before developing greyish-brown mottling as it matures. Mature truffles have an odor resembling garlicky cheese, similar to mature Camembert. The species has been harvested for culinary purposes in Oregon.
Tuber sinoalbidum is a species of truffle in the family Tuberaceae. Known only from China, it was described as a new species in 2011. Fresh truffles are whitish with a similarly colored interior, and measure up to 4.5 cm (1.8 in) in diameter.
Scleroderma verrucosum is a basidiomycete fungus and a member of the genus Scleroderma, or "earth balls". First described scientifically in 1791, the species has a cosmopolitan distribution, and grows in the ground in nutrient-rich, sandy soils.
Calostoma cinnabarinum, commonly known as the stalked puffball-in-aspic,gelatinous stalked-puffball, or red slimy-stalked puffball, is a species of gasteroid fungus in the family Sclerodermataceae, and is the type species of the genus Calostoma. The fruit body has a distinctive color and overall appearance, featuring a layer of yellowish jelly surrounding a bright red, spherical head approximately 2 centimeters (0.8 in) in diameter atop a red or yellowish brown spongy stipe 1.5 to 4 cm tall. The innermost layer of the head is the gleba, containing clear or slightly yellowish elliptical spores, measuring 14–20 micrometers (μm) long by 6–9 μm across. The spore surface features a pattern of small pits, producing a net-like appearance. A widely distributed species, it grows naturally in eastern North America, Central America, northeastern South America, and East Asia. C. cinnabarinum grows on the ground in deciduous forests, where it forms mycorrhizal associations with oaks.
Sclerodermatineae is a suborder of the fungal order Boletales. Circumscribed in 2002 by mycologists Manfred Binder and Andreas Bresinsky, it contains nine genera and about 80 species. The suborder contains a diverse assemblage fruit body morphologies, including boletes, gasteroid forms, earthstars, and puffballs. Most species are ectomycorrhizal, although the ecological role of some species is not known with certainty. The suborder is thought to have originated in the late Cretaceous (145–66 Ma) in Asia and North America, and the major genera diversified around the mid Cenozoic (66–0 Ma).
Harrya chromapes, commonly known as the yellowfoot bolete or the chrome-footed bolete, is a species of bolete fungus in the family Boletaceae. The bolete is found in eastern North America, Costa Rica, and eastern Asia, where it grows on the ground, in a mycorrhizal association with deciduous and coniferous trees. Fruit bodies have smooth, rose-pink caps that are initially convex before flattening out. The pores on the cap undersurface are white, aging to a pale pink as the spores mature. The thick stipe has fine pink or reddish dots (scabers), and is white to pinkish but with a bright yellow base. The mushrooms are edible but are popular with insects, and so they are often infested with maggots.
