Puffball

Last updated
Puffballs are found in several genera of the division Basidiomycota.

Puffballs are a type of fungus featuring a ball-shaped fruit body that (when mature) bursts on contact or impact, releasing a cloud of dust-like spores into the surrounding area. Puffballs belong to the division Basidiomycota and encompass several genera, including Calvatia , Calbovista and Lycoperdon . [1] The puffballs were previously treated as a taxonomic group called the Gasteromycetes or Gasteromycetidae, but they are now known to be a polyphyletic assemblage.

The distinguishing feature of all puffballs is that they do not have an open cap with spore-bearing gills. Instead, spores are produced internally, in a spheroidal fruit body called a gasterothecium (gasteroid 'stomach-like' basidiocarp). As the spores mature, they form a mass called a gleba in the centre of the fruitbody that is often of a distinctive color and texture. The basidiocarp remains closed until after the spores have been released from the basidia. Eventually, it develops an aperture, or dries, becomes brittle, and splits, and the spores escape. The spores of puffballs are statismospores rather than ballistospores, meaning they are not forcibly extruded from the basidium. Puffballs and similar forms are thought to have evolved convergently (that is, in numerous independent events) from Hymenomycetes by gasteromycetation, through secotioid stages. Thus, 'Gasteromycetes' and 'Gasteromycetidae' are now considered to be descriptive, morphological terms (more properly gasteroid or gasteromycetes, to avoid taxonomic implications) but not valid cladistic terms.

True puffballs do not have a visible stalk or stem, while stalked puffballs do have a stalk that supports the gleba. None of the stalked puffballs are edible as they are tough and woody mushrooms. [2] The Hymenogastrales and Enteridium lycoperdon , a slime mold, are the false puffballs. A gleba which is powdery on maturity is a feature of true puffballs, stalked puffballs and earthstars. False puffballs are hard like rock or brittle. All false puffballs are inedible, as they are tough and bitter to taste. The genus Scleroderma , which has a young purple gleba, should also be avoided. [2]

Puffballs were traditionally used in Tibet for making ink by burning them, grinding the ash, then putting them in water and adding glue liquid and "a nye shing ma decoction", which, when pressed for a long time, made a black dark substance that was used as ink. [3] Rural Americans burned the common puffball with some kind of bee smoker to anesthetize honey bees as a means to safely procure honey; the practice later inspired experimental medicinal application of the puffball smoke as a surgical general anesthetic in 1853. [4]

Edibility and identification

While most puffballs are not poisonous, some often look similar to young agarics, and especially the deadly Amanitas, such as the death cap or destroying angel mushrooms. Young puffballs in the edible stage, before maturation of the gleba, have undifferentiated white flesh within, whereas the gills of immature Amanita mushrooms can be seen if they are closely examined. They can be very toxic.

The giant puffball, Calvatia gigantea (earlier classified as Lycoperdon giganteum), reaches a foot (30 cm) or more in diameter, and is difficult to mistake for any other fungus. It has been estimated that, when mature, a large specimen of this fungus will produce around 7 × 10¹² spores.

Not all true puffball mushrooms are without stalks.[ inconsistent ] Some may also be stalked, such as the Podaxis pistillaris , which is also called the "false shaggy mane". There are also a number of false puffballs that look similar to the true ones. [2]

The Agaricaceae are a family of basidiomycete fungi and include the genus Agaricus, as well as basidiomycetes previously classified in the families Tulostomataceae, Lepiotaceae, and Lycoperdaceae.

<i>Calvatia gigantea</i> Species of mushroom

Calvatia gigantea, commonly known as the giant puffball, is a puffball mushroom commonly found in meadows, fields, and deciduous forests usually in late summer and autumn. It is found in temperate areas throughout the world.

<i>Calvatia</i> Genus of fungi

Calvatia is a genus of puffball mushrooms that includes the spectacular giant puffball C. gigantea. It was formerly classified within the now-obsolete order Lycoperdales, which, following a restructuring of fungal taxonomy brought about by molecular phylogeny, has been split; the puffballs, Calvatia spp. are now placed in the family Agaricaceae of the order Agaricales.

<i>Lycoperdon perlatum</i> Species of puffball fungus in the family Agaricaceae with a cosmopolitan distribution

Lycoperdon perlatum, popularly known as the common puffball, warted puffball, gem-studded puffball or devil's snuff-box, is a species of puffball fungus in the family Agaricaceae. A widespread species with a cosmopolitan distribution, it is a medium-sized puffball with a round fruit body tapering to a wide stalk, and dimensions of 1.5 to 6 cm wide by 3 to 10 cm tall. It is off-white with a top covered in short spiny bumps or "jewels", which are easily rubbed off to leave a netlike pattern on the surface. When mature it becomes brown, and a hole in the top opens to release spores in a burst when the body is compressed by touch or falling raindrops.

<i>Calvatia craniiformis</i> Species of puffball fungus

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.

<i>Apioperdon</i> Genus of fungi

Apioperdon pyriforme commonly known as the pear-shaped puffball or stump puffball, is a saprobic fungus present throughout much of the world. Emerging in autumn, this puffball is common and abundant on decaying logs of both deciduous and coniferous wood. It is considered a choice edible when still immature and the inner flesh is white. It is often called Lycoperdon pyriforme, but was transferred to Apioperdon in 2017 based on phylogenetic and morphological differences. It is the only species in the genus.

<i>Podaxis pistillaris</i> Species of fungus

Podaxis pistillaris is a very distinctive relative of the puffballs. It is commonly known as the desert shaggy mane, as it bears a superficial resemblance to the shaggy mane, Coprinus comatus; this species lacks the latter's deliquescing gills, however, and the two are not closely related. It grows to 15 cm high and has a hard, woody stem. The large cap, which protects the blackish spore-bearing tissue, splits, and usually falls away at maturity, allowing the spores to be dispersed by wind. Large numbers may appear after soaking rains. It thrives in deserts and semi-deserts of Australia and other countries, often found on termite mounds in South Africa. In the Hawaiian Islands, it is frequently encountered along roadsides and in disturbed areas on the dry sides of the islands, especially in the Kona area of Hawaii and the Kihei area of Maui.

<i>Bovista</i> Genus of fungi

Bovista is a genus of fungi commonly known as the true puffballs. It was formerly classified within the now-obsolete order Lycoperdales, which, following a restructuring of fungal taxonomy brought about by molecular phylogeny, has been split; the species of Bovista are now placed in the family Agaricaceae of the order Agaricales. Bovista species have a collectively widespread distribution, and are found largely in temperate regions of the world. Various species have historically been used in homeopathic preparations.

<i>Bovista plumbea</i> Species of fungus

Bovista plumbea, also referred to as the paltry puffball, is a small puffball mushroom commonly found in Western Europe and California, white when young and greyish in age. Easily confused with immature Bovista dermoxantha, it is attached to the substrate by a tuft of mycelium.

<i>Bovista nigrescens</i> Species of fungus

Bovista nigrescens, commonly referred to as the brown puffball or black bovist, is an edible cream white or brown puffball. Phylogenetic relationships between Bovista nigrescens and species of Lycoperdaceae were established based on ITS and LSU sequence data from north European taxa.

<i>Handkea utriformis</i> Species of fungus

Handkea utriformis, synonymous with Lycoperdon utriforme, Lycoperdon caelatum or Calvatia utriformis, is a species of the puffball family Lycoperdaceae. A rather large mushroom, it may reach dimensions of up to 25 cm (10 in) broad by 20 cm (8 in) tall. It is commonly known as the mosaic puffball, a reference to the polygonal-shaped segments the outer surface of the fruiting body develops as it matures. Widespread in northern temperate zones, it is found frequently on pastures and sandy heaths, and is edible when young. H. utriformis has antibiotic activity against a number of bacteria, and can bioaccumulate the trace metals copper and zinc to relatively high concentrations.

<i>Handkea</i> Genus of fungi

Handkea is a genus of puffball mushrooms in the family Agaricaceae. In 1989, German mycologist Hanns Kreisel described the genus Handkea to include species of Calvatia with distinct microscopic features, including a unique type of capillitium, with curvy slits instead of the usual pores. Although accepted by some authors, the genus concept has been rejected by others.

<i>Bovista aestivalis</i> Species of fungus

Bovista aestivalis is a small puffball in the family Agaricaceae. It is generally found in the coastal regions of California, but was reported from Korea in 2015. This fungus is often confused with Bovista dermoxantha, because of its similar peridium, and Bovista plumbea. The surest way to tell the species apart is to examine the spores and exoperidium, respectively, with a microscope.

<i>Calvatia cyathiformis</i> Species of fungus

Calvatia cyathiformis, or purple-spored puffball, is a large edible saprobic species of Calvatia. This terrestrial puffball has purplish or purple-brown spores, which distinguish it from other large Agaricales. It is found mostly in prairie or grasslands of North America, Australia, and Saiyan Village, Pakistan.

<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>Mycenastrum</i> Genus of fungi

Mycenastrum is a fungal genus in the family Agaricaceae. The genus is monotypic, containing one widely distributed species, Mycenastrum corium, known by various common names: the giant pasture puffball, leathery puffball, or tough puffball. The roughly spherical to turnip-shaped puffball-like fruit bodies grow to a diameter of 6–24 cm (2–9 in). Initially covered by a thick, felted, whitish layer, the puffballs develop a characteristic checkered skin (peridium) in age. When the internal spore mass, the gleba, is firm and white, the puffball is edible, although some individuals may suffer mild gastrointestinal symptoms after eating it. As the spores mature, the gleba turns first yellowish then purplish brown. Spores are released when the peridium eventually splits open into irregularly shaped sections. Microscopically, the gleba consists of spherical, dark brown spores with rounded bumps on their surfaces, and a capillitium—intricately branched fibers that form long thorn-like spines. The puffball grows on or in the ground in prairie or desert habitats. Although widely distributed, it is not commonly encountered. Mycenastrum corium is a threatened species in Europe.

<i>Lycoperdon echinatum</i> Species of puffball mushroom

Lycoperdon echinatum, commonly known as the spiny puffball or the spring puffball, is a type of puffball mushroom in the family Agaricaceae. The saprobic species has been found in Africa, Europe, Central America, and North America, where it grows on soil in deciduous woods, glades, and pastures. It has been proposed that North American specimens be considered a separate species, Lycoperdon americanum, but this suggestion has not been followed by most authors. Molecular analysis indicates that L. echinatum is closely related to the puffball genus Handkea.

<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>Handkea excipuliformis</i>

Handkea excipuliformis, commonly known as the pestle puffball or long-stemmed puffball, is a species of the family Agaricaceae. A rather large puffball, it may reach dimensions of up to 15 cm (5.9 in) broad by 25 cm (9.8 in) tall. Widespread in northern temperate zones, it is found frequently on pastures and sandy heaths.

<i>Lycoperdon marginatum</i> Species of fungus

Lycoperdon marginatum, commonly known as the peeling puffball, is a type of puffball mushroom in the genus Lycoperdon. A common species, it is found in Europe and North America, where it grows on the ground. It is characterized by the way that the spiny outer layer peels off in sheets.
