Mycocalia is a genus of fungi in the family Nidulariaceae. Basidiocarps (fruit bodies) are minute (typically under 5 mm in diameter) and irregularly spherical. Each produces one or more peridioles which contain the spores and are released from the disintegrating fruit bodies at maturity. Species are usually found growing on herbaceous stems and other plant debris. The genus was originally described in 1961 by British mycologist J.T. Palmer [1] and has a north temperate distribution. [2]

Description

Species have small barrel- to lens-shaped fruit bodies, 0.5–5 mm broad, that grow singly or in small groups. The peridium consists of loosely interwoven clamped hyphae. The peridioles, of which there may be one to several, are disc-shaped, yellow- to red-brown, and sit in a gelatinous matrix when young and fresh. Spores are elliptical, smooth, and hyaline. [3]

<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>Scleroderma</i> (fungus) Genus of fungi

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.

<i>Cyathus striatus</i> Species of fungus

Cyathus striatus, commonly known as the fluted bird's nest, is a common saprobic bird's nest fungus with a widespread distribution throughout temperate regions of the world. This fungus resembles a miniature bird's nest with numerous tiny "eggs"; the eggs, or peridioles, are actually lens-shaped bodies that contain spores. C. striatus can be distinguished from most other bird's nest fungi by its hairy exterior and grooved inner walls. Although most frequently found growing on dead wood in open forests, it also grows on wood chip mulch in urban areas. The fruiting bodies are encountered from summer until early winter. The color and size of this species can vary somewhat, but they are typically less than a centimeter wide and tall, and grey or brown in color. Another common name given to C. striatus, splash cups, alludes to the method of spore dispersal: the sides of the cup are angled such that falling drops of water can dislodge the peridioles and eject them from the cup. The specific epithet is derived from the Latin stria, meaning "with fine ridges or grooves".

<i>Crucibulum</i> Genus of fungi

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.

<i>Nidularia</i> Genus of fungi

Nidularia is a genus of nine species of fungi in the family Agaricaceae. Their fruit bodies resemble tiny egg-filled bird nests. The name comes from the Latin nidus meaning nest. The related genus Mycocalia was segregated from Nidularia in 1961 based on differences in the microscopic structure of the peridium.

<i>Nidula</i> Genus of fungi

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.

<i>Cyathus</i> Genus of fungi in the Nidulariaceae

Cyathus is a genus of fungi in the Nidulariaceae, which is a family collectively known as the bird's nest fungi. They are given this name as they resemble tiny bird's nests filled with "eggs" – structures large enough to have been mistaken in the past for seeds. However, these are now known to be reproductive structures containing spores. The "eggs", or peridioles, are firmly attached to the inner surface of this fruit body by an elastic cord of mycelia known as a funiculus. The 45 species are widely distributed throughout the world and some are found in most countries, although a few exist in only one or two locales. Cyathus stercoreus is considered endangered in a number of European countries. Some species of Cyathus are also known as splash cups, which refers to the fact that falling raindrops can knock the peridioles out of the open-cup fruit body. The internal and external surfaces of this cup may be ridged longitudinally ; this is one example of a taxonomic characteristic that has traditionally served to distinguish between species.

<i>Cyathus olla</i> Species of fungus

Cyathus olla also known as the field bird's nest is a species of saprobic fungus in the genus Cyathus of the family Nidulariaceae. The fruit bodies resemble tiny bird's nests filled with "eggs" – spore-containing structures called peridioles. Like other bird's nest fungi, C. olla relies on the force of falling water to dislodge peridioles from fruiting bodies to eject and disperse their spores. The life cycle of this fungus allows it to reproduce both sexually, with meiosis, and asexually via spores. C. olla is a relatively common fungus, with a worldwide distribution. It is the subject of agricultural research to determine its potential as a means to accelerate the breakdown of crop residue, and reduce the population of plant pathogens. The specific epithet is derived from the Latin word olla, meaning "pot".

<i>Cyathus helenae</i> Species of fungus

Cyathus helenae or Helena's bird's nest is a species of fungus in the genus Cyathus, family Nidulariaceae. Like other members of the Nidulariaceae, C. helenae resembles a tiny bird's nest filled with 'eggs'—spore-containing structures known as peridioles. It was initially described by mycologist Harold Brodie in 1965, who found it growing on mountain scree in Alberta, Canada. C. helenae's life cycle allows it to reproduce both sexually and asexually. One of the smaller species of Cyathus, C. helenae produces a number of chemically unique diterpenoid molecules known as cyathins. The specific epithet of this species was given by Brodie in tribute to his late wife Helen.

<i>Geastrum pectinatum</i> Species of fungus

Geastrum pectinatum is an inedible species of mushroom belonging to the earthstar family of fungi. Although young specimens are spherical, fruit body development involves the outer layer of tissue splitting open like a star into 7 to 10 pointed rays that eventually bend back to point downward, revealing a small – 1 to 2.5 cm broad – spore sac. The spore sac is supported by a small radially wrinkled stalk. There is a distinct conical opening (peristome) at the top of the spore sac that is up to 8 mm (0.3 in) long. It is commonly known as the beaked earthstar or the beret earthstar, in reference to the shape of the spore sac and its prominent, protruding peristome. The mass of spores and surrounding cells within the sac, the gleba, is dark-brown, and becomes powdery in mature specimens. Spores are spherical, measuring 4 to 6 micrometers in diameter, with warts on their surfaces. Although uncommon, Geastrum pectinatum has a cosmopolitan distribution, and has been collected in various locations in Europe, North and South America, Asia, Australia and Africa, where it grows on the ground in open woods. Like several other earthstars, crystals of calcium oxalate are found on G. pectinatum, and are thought to be involved in fruit body maturation.

<i>Astraeus</i> (fungus) Genus of fungi

Astraeus is a genus of fungi in the family Diplocystaceae. The genus, which has a cosmopolitan distribution, contains nine species of earthstar mushroom. They are distinguished by the outer layer of flesh (exoperidium) that at maturity splits open in a star-shape manner to reveal a round spore sac. Additionally, they have a strongly hygroscopic character—the rays will open when moist, but when hot and dry will close to protect the spore sac. Species of Astraeus grow on the ground in ectomycorrhizal associations with trees and shrubs. Despite their similar appearance to the Geastrum earthstars Astraeus is not closely related.

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.

<i>Calbovista</i> Genus of fungi

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.

<i>Agaricus deserticola</i> Species of fungus in the family Agaricaceae endemic to southwestern and western North America

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.

<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>Geastrum quadrifidum</i> Species of fungus in the family Geastraceaea

Geastrum quadrifidum, commonly known as the rayed earthstar or four-footed earthstar, is an inedible species of mushroom belonging to the genus Geastrum, or earthstar fungi. First described scientifically by Christian Hendrik Persoon in 1794, G. quadrifidum is a cosmopolitan—but not common—species of Europe, the Americas, Africa, Asia, and Australasia. The fungus is a saprobe, feeding off decomposing organic matter present in the soil and litter of coniferous forests.

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

The Nidulariaceae are a family of fungi in the order Agaricales. Commonly known as the bird's nest fungi, their fruiting bodies resemble tiny egg-filled birds' nests. As they are saprobic, feeding on decomposing organic matter, they are often seen growing on decaying wood and in soils enriched with wood chips or bark mulch; they have a widespread distribution in most ecological regions. The five genera within the family, namely, Crucibulum, Cyathus, Mycocalia, Nidula, and Nidularia, are distinguished from each other by differences in morphology and peridiole structure; more recently, phylogenetic analysis and comparison of DNA sequences is guiding new decisions in the taxonomic organization of this family.

Retiperidiolia is a genus of fungi in the family Nidulariaceae. Basidiocarps are typically under 10 mm in diameter and irregularly spherical. Each produces a number of peridioles which contain the spores and are released from the disintegrating fruit bodies at maturity. Species are usually found growing on herbaceous stems and other plant debris. The genus has a tropical distribution. Species were previously referred to Mycocalia, but molecular research, based on cladistic analysis of DNA sequences, found that they were not closely related.
