Marasmius is a genus of mushroom-forming fungi in the family Marasmiaceae. It contains about 500 species of agarics, [1] of which a few, such as Marasmius oreades , are edible. However, most members of this genus are small, unimpressive brown mushrooms. Their humble appearance contributes to their not being readily distinguishable to non-specialists, and they are therefore seldom collected by mushroom hunters. Several of the species are known to grow in the characteristic fairy ring pattern.

The author of the genus was Elias Magnus Fries, [2] who in 1838 [3] classified white-spored agarics having a tough central stipe in this taxon if they were marcescent, i.e. they could dry out but later revive when moistened. For Fries, marcescenceby contrast with the "putrescent" (decomposing) nature of most mushroomswas an important character for classification, which he used to separate this group from genus Collybia (which has now been split into many newer genera). The name Marasmius itself comes from the Greek word marasmos, meaning "drying out; withering". Modern mycologists no longer consider the marcescence/putrescence distinction a reliable criterion for taxonomy, but Fries's definition of the genus is still roughly applicable.

Species

Below is a list of more prominent species (for a complete list see List of Marasmius species). Note that some well-known former members of Marasmius, such as M. alliaceus , have been moved into the new genus Mycetinis ; a few others have been reclassified as Rhizomarasmius or Gloiocephala . Former M. androsaceus is now considered to belong to genus Gymnopus .

Edible mushrooms are the fleshy fruit bodies of several species of macrofungi. Edibility may be defined by criteria including the absence of poisonous effects on humans and desirable taste and aroma. Mushrooms that have a particularly desirable taste are described as "choice". Edible mushrooms are consumed for their nutritional and culinary value. Mushrooms, especially dried shiitake, are sources of umami flavor.

<i>Clitocybe</i> Genus of fungi

Clitocybe is a genus of mushrooms characterized by white, off-white, buff, cream, pink, or light-yellow spores, gills running down the stem, and pale white to brown or lilac coloration. They are primarily saprotrophic, decomposing forest ground litter. There are estimated to be around 300 species in the widespread genus.

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

The Marasmiaceae are a family of fungi in the order Agaricales. Basidiocarps are most frequently agarics, but occasionally cyphelloid. According to a 2008 estimate, the family contained 54 genera and 1590 species, but molecular research, based on cladistic analysis of DNA sequences, has led to a more restricted family concept, so that the Marasmiaceae included just 13 genera, and some 1205 species. It was reduced further down in 2020, to 10 genera and about 700 species.

<i>Agaricus campestris</i> Species of fungus

Agaricus campestris is a widely eaten gilled mushroom closely related to the cultivated A. bisporus. A. campestris is commonly known as the field mushroom or, in North America, meadow mushroom.

<i>Clitocybe dealbata</i> Species of fungus

Clitocybe dealbata, also known as the ivory funnel, is a small white funnel-shaped basidiomycete fungus widely found in lawns, meadows and other grassy areas in Europe and North America. Also known as the sweating mushroom, or sweat producing clitocybe, it derives these names from the symptoms of poisoning. It contains potentially deadly levels of muscarine.

<i>Marasmius oreades</i> Species of fungus

Marasmius oreades, also known as the fairy ring mushroom, fairy ring champignon or Scotch bonnet, is a mushroom native to North America and Europe. Its common names can cause some confusion, as many other mushrooms grow in fairy rings, such as the edible Agaricus campestris and the poisonous Chlorophyllum molybdites.

<i>Lepiota brunneoincarnata</i> Species of fungus

Lepiota brunneoincarnata, the deadly dapperling, is a gilled mushroom of the genus Lepiota in the order Agaricales. Widely distributed in Europe and temperate regions of Asia as far east as China, it grows in grassy areas such as fields, parks and gardens, and is often mistaken for edible mushrooms. The mushroom has a brown scaled cap up to 4 cm wide with a pinkish brown stem and white gills. It is highly toxic, with several deaths having been recorded as it resembles the edible grey knight and fairy ring champignon.

<i>Clitocybe rivulosa</i> Species of fungus

Clitocybe rivulosa, commonly known as the false champignon or fool's funnel, is a poisonous basidiomycete fungus of the large genus Clitocybe. One of several species similar in appearance, it is a small white funnel-shaped toadstool widely found in lawns, meadows and other grassy areas in Europe and North America. Also known as the sweating mushroom, it derives this name from the symptoms of poisoning. It contains potentially deadly levels of muscarine.

<i>Mycetinis alliaceus</i> Species of fungus

Mycetinis alliaceus, commonly known as the garlic parachute, is one of the larger mushrooms formerly in the genus Marasmius, having a beige cap of up to 4 cm and a long tough slender stipe. It emanates a strong smell of garlic, and this is the significance of the Latin species name, alliaceus. It is distributed throughout Europe, being fairly common in some areas and quite rare in others.

<i>Collybia</i> Genus of fungi

Collybia is a genus of mushrooms in the family Tricholomataceae. The genus has a widespread but rare distribution in northern temperate areas, and contains three species that grow on the decomposing remains of other mushrooms.

Epicnaphus is a genus of mushroom-forming fungi in the family Marasmiaceae. The genus, circumscribed by mycologist Rolf Singer in 1960, contains two species found in South America. Fruitbodies of Epicnaphus species are similar in appearance to those in Marasmius section Sicci, but have a smooth hymenium and broom cells of the Rotalis-type. Singer initially included only the type species, E. phalaropus, which was originally collected from fallen branches in a Bolivian rainforest. The Argentinian species E. longispora was added to the genus by Jörg Raithelhuber in 1973.

<i>Mycetinis</i> Genus of fungi

Mycetinis is a genus of fungus in the Omphalotaceae family, containing about eight species formerly classified in Marasmius.

<i>Amanita regalis</i> Species of fungus

Amanita regalis, commonly known as the royal fly agaric or the king of Sweden Amanita, is a species of fungus in the family Amanitaceae. A. regalis has a scabby liver-brown cap and a stem which is yellow-ochre at the base, with patches or rings of patches. The fruit bodies somewhat resemble the smaller A. muscaria, which it was formerly regarded as a variety of.

<i>Marasmius rotula</i> Species of fungus

Marasmius rotula is a common species of agaric fungus in the family Marasmiaceae. Widespread in the Northern Hemisphere, it is commonly known variously as the pinwheel mushroom, the pinwheel marasmius, the little wheel, the collared parachute, or the horse hair fungus. The type species of the genus Marasmius, M. rotula was first described scientifically in 1772 by mycologist Giovanni Antonio Scopoli and assigned its current name in 1838 by Elias Fries.

<i>Archaeomarasmius</i> Extinct genus of fungi

Archaeomarasmius is an extinct genus of gilled fungus in the Agaricales family Tricholomataceae, containing the single species Archaeomarasmius leggetti. It is known from two fruit bodies recovered from amber, one consisting of a complete cap with a broken stem, the other consisting of a fragment of a cap. The cap has a diameter ranging from 3.2 to 6 mm, while the stem is 0.5 mm (0.02 in) thick. Spores were also recovered from the amber, and are broadly ellipsoid to egg-shaped, measuring roughly 7.3 by 4.7 μm. The species, which resembles the extant genera Marasmius and Marasmiellus, is inferred to have been saprobic on plant litter or other forest debris.

<i>Marasmius fulvoferrugineus</i> Species of fungus

Marasmius fulvoferrugineus is a species of agaric fungus in the family Marasmiaceae. Described as new to science in 1976, it is found in the southeastern United States. The mushroom is frequently confused with Marasmius siccus, and microscopy is needed to reliably distinguish between them.

<i>Marasmius tageticolor</i> Species of fungus

Marasmius tageticolor is a species of agaric fungus in the family Marasmiaceae. Its fruit bodies have striped red and white caps. It is found in Mexico, Central America, and South America, where it grows on twigs.

<i>Collybiopsis peronata</i> Species of fungus
