Rhizomarasmius setosus (syn. Marasmius setosus or Marasmius recubans) is a tiny whitish mushroom having a distinctive hairy stem. [2] [3] [1] It has been given the vernacular name "Beechleaf Parachute". [4]

Description

The species can be described as follows: [2] [3] [5]

The species epithet comes from the Latin adjective "saetosus" or "setosus", meaning "coarsely hairy". That word in turn derives from "saeta" (or "seta"), a bristle. [6]

This species was originally described in 1801 as Agaricus setosus by James Sowerby in his historic work "Coloured Figures of English Fungi or Mushrooms". The French mycologist Lucien Quélet independently described the species under the name Marasmius recubans in 1873, but much later in 1987 Machiel Noordeloos determined that Sowerby's name takes precedence and defined the combination Marasmius setosus for it. Then in 2015 Vladimír Antonín and Alexander Urban transferred it to the new genus Rhizomarasmius . [1]

Marasmius saccharinus is a similar fungus which has been confused with R. setosus by some authors, but which, however, lacks the hairs on the stipe. There are other tiny Marasmius species such as M. epiphyllus which are comparable but which again have a bald stipe. [2]

Ecology and distribution

This mushroom grows on dead beech leaves, or occasionally on other deciduous leaves such as willow or birch. [2] [3] It is widely distributed in central and western Europe. [2] [3]

<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.

<i>Dendrocollybia</i> Genus of fungi in the family Tricholomataceae

Dendrocollybia is a fungal genus in the family Tricholomataceae of the order Agaricales. It is a monotypic genus, containing the single species Dendrocollybia racemosa, commonly known as the branched Collybia or the branched shanklet. The somewhat rare species is found in the Northern Hemisphere, including the Pacific Northwest region of western North America, and Europe, where it is included in several Regional Red Lists. It usually grows on the decaying fruit bodies of other agarics—such as Lactarius and Russula—although the host mushrooms may be decayed to the point of being difficult to recognize.

<i>Entoloma austroprunicolor</i> Species of fungus

Entoloma austroprunicolor is a species of agaric fungus in the family Entolomataceae. Described as new to science in 2007, it is found in Tasmania, where it fruits on the ground of wet sclerophyll forests in late spring to early winter. The fruit bodies (mushrooms) have reddish-purple caps measuring up to 5 cm (2.0 in) in diameter supported by whitish stipes measuring 3–7.5 cm (1.2–3.0 in) long by 0.2–0.6 cm (0.1–0.2 in) thick. On the cap underside, the crowded gills are initially white before turning pink as the spores mature.

<i>Plectania nannfeldtii</i> Species of fungus

Plectania nannfeldtii, commonly known as Nannfeldt's Plectania, the black felt cup, or the black snowbank cup fungus, is a species of fungus in the family Sarcosomataceae. The fruit bodies of this species resemble small, black, goblet-shaped shallow cups up to 3 cm wide, with stems up to 4 cm long attached to black mycelia. Fruit bodies, which may appear alone or in groups on the ground in conifer duff, are usually attached to buried woody debris, and are commonly associated with melting snow. Plectania nannfeldtii is found in western North America and in Asia, often at higher elevations. Similar black cup fungi with which P. nannfeldtii may be confused include Pseudoplectania vogesiaca, P. nigrella, and Helvella corium.

<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>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>Roridomyces austrororidus</i> Species of fungus

Roridomyces austrororidus, commonly known as the austro dripping bonnet, is a species of agaric fungus in the family Mycenaceae. Described as new to science in 1962 by American mycologist Rolf Singer, it is found in South America, New Zealand, and Australia, where it grows on rotting wood.

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

Marasmius siccus, or orange pinwheel, is a small orange mushroom in the Marasmius genus, with a "beach umbrella"-shaped cap. The tough shiny bare stem is pale at the top but reddish brown below, and the gills are whitish. The stem is 3–7 centimetres (1.2–2.8 in) tall and the cap is 0.5–2.5 centimetres (0.20–0.98 in) wide.

<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>Gymnopus fusipes</i> Species of fungus

Gymnopus fusipes is a parasitic species of gilled mushroom which is quite common in Europe and often grows in large clumps. It is variable but easy to recognize because the stipe soon becomes distinctively tough, bloated and ridged.
