Rhizomarasmius epidryas (syn. Marasmius epidryas or Mycetinis epidryas) is one of a group of mushrooms formerly in the genus Marasmius . It grows amongst dwarf shrubs of the genus Dryas in arctic or high mountain environments. [2] [3] [1]

Description

The species can be described as follows: [2] [3] [4]

The species epithet is the Ancient Greek prefix "epi-" (ἐπί), meaning "on", [5] followed by Dryas, the genus of plants with which it grows.

This species was originally described as Marasmius epidryas by Robert Kühner in 1935 in the annals of the Linnaean Society of Lyon, but the definition was considered invalid due to the lack of a Latin description according to the updated nomenclatural rules. In 2009 Anna Ronikier published a correct description ascribing the name to Kühner (that is, giving credit to him) and so the first valid name with author attribution was "Marasmius epidryas Kühner ex A. Ronikier". Then in 2011 Anna & Macheł Ronikier established that the species belongs in the new genus Rhizomarasmius and redefined the current name accordingly. [6] [1]

Ecology and distribution

This mushroom is found exclusively in cushions of Dryas plants such as D. octopetala (mountain avens) and D. integrifolia (entire-leaved avens), growing saprobically on dead leaves and stems. It only occurs in arctic or high mountain environments. [2] [3]

It is reported from arctic regions of Europe and North America, the Rocky and Altai mountains, and various mountain ranges in Europe. [2] [3]

<i>Mythicomyces</i> Genus of fungi

Mythicomyces is a fungal genus in the family Mythicomycetaceae. A monotypic genus, it contains the single species Mythicomyces corneipes, first described by Elias Fries in 1861. The fungus produces fruit bodies with shiny yellowish-orange to tawny caps that are 1–3 cm (0.4–1.2 in) in diameter. These are supported by stems measuring 2–5.7 cm (0.8–2.2 in) long and 1–2 mm thick. A rare to uncommon species, it is found in northern temperate regions of North America and Europe, where it typically fruits in groups, in wet areas of coniferous forests. There are several species with which M. corneipes might be confused due to a comparable appearance or similar range and habitat, but microscopic characteristics can be used to reliably distinguish between them.

<i>Galerina sulciceps</i> Species of fungus

Galerina sulciceps is a dangerously toxic species of fungus in the family Strophariaceae, of the order Agaricales. It is distributed in tropical Indonesia and India, but has reportedly been found fruiting in European greenhouses on occasion. More toxic than the deathcap, G. sulciceps has been shown to contain the toxins alpha- (α-), beta- (β-) and gamma- (γ-) amanitin; a series of poisonings in Indonesia in the 1930s resulted in 14 deaths from the consumption of this species. It has a typical "little brown mushroom" appearance, with few obvious external characteristics to help distinguish it from many other similar nondescript brown species. The fruit bodies of the fungus are tawny to ochre, deepening to reddish-brown at the base of the stem. The gills are well-separated, and there is no ring present on the stem.

<i>Rhizomarasmius</i> Genus of fungi

Rhizomarasmius is a genus of fungi in the family Physalacriaceae, containing about five species.

<i>Mycena nargan</i> Species of fungus in the family Mycenaceae

Mycena nargan, commonly known as the Nargan's bonnet, is a species of fungus in the family Mycenaceae, and the sole member of the section Nargan in the genus Mycena. Reported as a new species in 1995, it is known predominantly from Southern Australia. The saprobic fungus produces mushrooms that grow on well-decayed wood, often on the underside of wood lying in litter. The dark chestnut-coloured caps are covered with white, easily removed scales, and reach diameters of up to 2 cm (0.8 in) wide. The pale, slender stems are up to 5 cm (2.0 in) long and have white scales at the base. On the underside of the cap, the cream-coloured gills are widely spaced and bluntly attached to the stem. The edibility of the mushroom is unknown.

<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>Psilocybe hispanica</i> Species of fungus in the family Hymenogastraceae

Psilocybe hispanica is a species of fungus in the family Hymenogastraceae. It produces small brown mushrooms with conical to convex caps up to 10 mm (0.4 in) in diameter and stems 16 to 25 mm long by 0.5 to 1 mm thick. Reported as new to science in 2000, it is only known from the Pyrenees mountain range in northern Spain and southwestern France, where it grows on horse dung in grass fields at elevations of 1,700 to 2,300 m. The mushroom contains the psychoactive compound psilocybin. The possible depiction of this species in the 6,000-year-old Selva Pascuala rock art suggests that it might have been used in ancient religious rituals—the oldest evidence of such usage in prehistoric Europe.

<i>Psilocybe makarorae</i> Species of fungus

Psilocybe makarorae is a species of psilocybin mushroom in the family Hymenogastraceae. Officially described as new to science in 1995, it is known only from New Zealand, where it grows on rotting wood and twigs of southern beeches. The fruit body (mushroom) has a brownish cap with lighter coloured margins, measuring up to 3.5 cm (1.4 in) wide. The cap shape is either conical, bell-shaped, or flat depending on the age of the mushroom, and it features a prominent umbo. Although the whitish stem does not form a true ring, it retains remnants of the partial veil that covers and protects the gills of young fruit bodies. P. makarorae mushrooms can be distinguished from the similar North American species Psilocybe caerulipes by microscopic characteristics such as the presence of cystidia on the gill faces (pleurocystidia), and cheilocystidia with more elongated necks. Based on the bluing reaction to injury, P. makarorae is presumed to contain the psychedelic compounds psilocybin and psilocin.

<i>Crinipellis zonata</i> Species of fungus

Crinipellis zonata, commonly known as the zoned Crinipellis or the zoned-cap Collybia, is a species of gilled mushroom in the family Marasmiaceae. Though considered a little brown mushroom of unknown edibility, it is distinctive because of its thick covering of coarse hairs, and differentiated from other members of Crinipellis by its slightly larger cap size, which reaches up to 25 mm (1.0 in) in diameter. The white gills on the underside of the cap are crowded closely together, and are free from attachment to the stem. Saprobic, it grows on the dead wood of deciduous trees from late summer to autumn. The fungus is found commonly in eastern North America, but has also been collected in Portugal and Korea. The variety C. zonata var. cremoricolor, found in eastern North America, may be distinguished microscopically by its longer spores.

<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>Collybia cookei</i> Species of fungus

Collybia cookei is a species of fungus in the family Tricholomataceae, and one of three species in the genus Collybia. It is known from Europe, Asia, and North America. The fungus produces fruit bodies that usually grow on the decomposing remains of other mushrooms, like Meripilus giganteus, Inonotus hispidus, or species of Russula; occasionally fruit bodies are found on rich humus or well-decayed wood. The fungus produces small white mushrooms with caps up to 9 mm (0.35 in) in diameter, supported by thin stems that originate from a yellowish-brown sclerotium. The mushroom is difficult to distinguish from the other two species of Collybia unless an effort is made to examine the sclerotia, which is usually buried in the substrate. The edibility of the mushroom has not been determined.

<i>Collybia cirrhata</i> Species of fungus

Collybia cirrhata is a species of fungus in the family Tricholomataceae of the order Agaricales. The species was first described in the scientific literature in 1786, but was not validly named until 1803. Found in Europe, Northern Eurasia, and North America, it is known from temperate, boreal, and alpine or arctic habitats. It is a saprobic species that grows in clusters on the decaying or blackened remains of other mushrooms. The fruit bodies are small, with whitish convex to flattened caps up to 11 mm in diameter, narrow white gills, and slender whitish stems 8–25 mm long and up to 2 mm (0.08 in) thick. C. cirrhata can be distinguished from the other two members of Collybia by the absence of a sclerotium at the base of the stem. The mushroom is of unknown edibility.
