In fungi, a basidiocarp, basidiome, or basidioma (pl. basidiomata) is the sporocarp of a basidiomycete, the multicellular structure on which the spore-producing hymenium is borne. Basidiocarps are characteristic of the hymenomycetes; rusts and smuts do not produce such structures. As with other sporocarps, epigeous (above-ground) basidiocarps that are visible to the naked eye are commonly referred to as mushrooms, while hypogeous (underground) basidiocarps are usually called false truffles.
Galerina is a genus of small brown-spore saprobic fungi, with over 300 species found throughout the world from the far north to remote Macquarie Island in the Southern Ocean. The genus is most noted for some extremely poisonous species which are occasionally confused with hallucinogenic species of Psilocybe. Species are typically small and hygrophanous, with a slender and brittle stem. They are often found growing on wood, and when on the ground have a preference for mossy habitats.
Hygrophoropsis aurantiaca, commonly known as the false chanterelle, is a species of fungus in the family Hygrophoropsidaceae. It is found across several continents, growing in woodland and heathland, and sometimes on woodchips used in gardening and landscaping. Fruit bodies (mushrooms) are yellow–orange, with a funnel-shaped cap up to 8 cm across that has a felt-like surface. The thin, often forked gills on the underside of the cap run partway down the length of the otherwise smooth stipe. Reports on the mushroom's edibility vary – it is considered poisonous, but has historically been eaten in parts of Europe and the Americas.
Galerina marginata, known colloquially as funeral bell, deadly skullcap, autumn skullcap or deadly galerina, is a species of extremely poisonous mushroom-forming fungus in the family Hymenogastraceae of the order Agaricales. It contains the same deadly amatoxins found in the death cap. Ingestion in toxic amounts causes severe liver damage with vomiting, diarrhea, hypothermia, and eventual death if not treated rapidly. About ten poisonings have been attributed to the species now grouped as G. marginata over the last century.
Atheliaceae is a family of corticioid fungi placed under the monotypic order Atheliales. Both the order and the family were described by Walter Jülich in 1981. According to a 2008 estimate, the family contains 20 genera and approximately 100 species. However, many genera formerly considered to belong in the Atheliaceae have since been moved to other families, including Amylocorticiaceae, Albatrellaceae, and Hygrophoraceae. Despite being a relatively small group with inconspicuous forms, Atheliaceae members show great diversity in life strategies and are widespread in distribution. Additionally, being a group strictly composed of corticioid fungi, they may also provide insights on the evolution of fruiting body forms in basidiomycetes.
Crucibulum is a genus in the Nidulariaceae, a family of fungi whose fruiting bodies resemble tiny egg-filled bird's nests. Often called "splash cups", the fruiting bodies are adapted for spore dispersal by using the kinetic energy of falling drops of rain. The "eggs" inside the bird's nests are hard waxy shells containing spores, and tend to stick to whatever nearby herbage they land on, thus increasing the odds of being consumed and dispersed by herbivorous animals. Members of this genus are saprobic, obtaining nutrients from dead organic matter, and are typically found growing on decayed wood and wood debris. The three known Crucibulum species are distinguished from other genera of the Nidulariaceae by their relatively simple funiculus – a cord of hyphae that connects the peridiole to the exterior of the bird's nest.
Nidula is a genus of fungi in the family Agaricaceae. Their fruit bodies resemble tiny egg-filled birds' nests, from which they derive their common name "bird's nest fungi". Originally described in 1902, the genus differs from the related genera Cyathus and Crucibulum by the absence of a cord that attaches the eggs to the inside of the fruit body. The life cycle of this genus allows it to reproduce both sexually, with meiosis, and asexually via spores. Species in this genus produce a number of bioactive compounds, including 4-(p-hydroxyphenyl)-2-butanone, a major component of raspberry flavor and insect attractor used in pesticides.
Lysurus mokusin, commonly known as the lantern stinkhorn, the small lizard's claw, or the ribbed lizard claw, is a saprobic species of fungus in the family Phallaceae. The fruit body consists of a reddish, cylindrical fluted stipe that is capped with several "arms". The arms can approach or even close in on each other to form a spire. The gleba—an olive-green slimy spore mass—is carried on the outer surface of the arms. The fruit body, which has an odor comparable to "fresh dog feces", "rotting flesh", or "sewage" when mature, is edible in its immature "egg" stage. The fungus is native to Asia, and is also found in Australia, Europe and North America, where it is probably an introduced species. It has been used medicinally in China as an ulcer remedy.
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.
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.
Episphaeria is a genus of fungus in the Agaricales. The genus is monotypic, and contains the single rare species Episphaeria fraxinicola, found in Europe. Its familial position is not known with certainty. The tiny fruit bodies of the fungus resemble minute, white cups that grow scattered or in groups on the bark of ash trees.
Nia is a genus of fungi in the family Niaceae. The genus contains three species adapted to a marine environment. All are wood-rotting fungi, producing small, gasteroid basidiocarps on driftwood, submerged timber, mangrove wood, and similar substrates. The type species, Nia vibrissa, is widespread in temperate and tropical seas.
Podoserpula is a genus of fungi in the family Amylocorticiaceae. The genus contains two species: the type, P. pusio, commonly known as the pagoda fungus, and the "Barbie pagoda", P. miranda, officially published in 2013. Podoserpula species produce fruit bodies consisting of up to a dozen caps arranged in overlapping shelves, attached to a central axis. Its unique shape is not known to exist in any other fungi. Four varieties of P. pusio are known, which differ in their sizes, spore morphology, and distribution. The genus is known to occur in Australia and New Zealand, Venezuela, Madagascar, and New Caledonia.
Xylobolus frustulatus, commonly known as the ceramic fungus or ceramic parchment, is an inedible species of crust fungus in the Stereaceae family. The fruit body forms small, hard, flat crust-like aggregations that resemble broken pieces of ceramic tile. These pieces are initially whitish before turning yellow-brown to gray-brown in age. The spore-bearing cells cover the upper surfaces of the fruit body. A saprobic species, it grows on well-decayed oak wood in Asia, northern Europe, and North America.
Scleroderma polyrhizum, commonly known as the star earthball or dead man's hand, is a basidiomycete fungus and a member of the genus Scleroderma, or "earthballs". Found in dry, sandy soils, this species begins completely buried before slowly forcing the soil aside as it cracks apart to form a rough, star-shaped body with a diameter of 12–15 cm (4.7–5.9 in). At the center is the dark, brownish spore mass. Widely distributed wherever the soil and climate are favorable, it is known from Asia, Europe, and the Americas.
Mycena purpureofusca, commonly known as the purple edge bonnet, is a species of agaric fungus in the family Mycenaceae. First described by Charles Horton Peck in 1885, the species is found in Europe and North America, where it grows on the decaying wood and debris of conifers, including cones. Fruit bodies have conical to bell-shaped purple caps up to 2.5 cm (1 in) set atop slender stipes up to 10 cm (4 in) long. The mushroom is named for the characteristic dark greyish-purple color of its gill edges. In the field, M. purpureofusca mushrooms can usually be distinguished from similar species by characteristics such as the dark purple gill edges, the deep purple cap center, and its cartilagineous consistency. The fungus contains a laccase enzyme that has been investigated scientifically for its potential to detoxify recalcitrant industrial dyes used in textile dyeing and printing processes.
Pholiota nubigena, commonly known as the gastroid pholiota or the bubble gum fungus, is a species of secotioid fungus in the family Strophariaceae. It is found in mountainous areas of the western United States, where it grows on rotting conifer wood, often fir logs. It fruits in spring, often under snow, and early summer toward the end of the snowmelt period in high mountain forests. Fruit bodies appear similar to unopened mushrooms, measuring 1–4 centimetres tall with 1–2.4 cm diameter caps that are whitish to brownish. They have a short but distinct whitish stipe that extend through the internal spore mass (gleba) of the fruit body into the cap. The gleba consists of irregular chambers made of contorted gills that are brownish in color. A whitish, cottony partial veil is present in young specimens, but it often disappears in age and does not leave a ring on the stipe.
Sistotrema brinkmannii, a resupinate wood-rotting basidiomycete, is a fungus found in soil, moss, debris, rotten woods as well as woods including seedling roots of Pinus banksiana Lamb. and ectomycorrhizae. No health issues caused by this fungus in human and animals have been reported although it is causative of brown rot. This fungus grows rapidly on malt extract agar (MEA), forming white mats with a faint sweet odour. It is commonly called "chain chlamydospore fungus" because bulbils are formed by chains of its cells that resemble chlamydospores. The basidia of this fungus are urniform and usually possess 6-8 sterigmata, and the spores are smooth and slightly curved.
