Gymnopilus is a genus of gilled mushrooms within the fungal family Hymenogastraceae containing over 200 [1] rusty-orange spored mushroom species.

Contents

Description

The fruit body is typically reddish brown to rusty orange to yellow, medium to large, often with a well-developed veil.

Similar genera

Members of Pholiota and Cortinarius are easy to confuse with Gymnopilus. Pholiota can be distinguished by its viscid cap and duller (brown to cinnamon brown) spores, and Cortinarius grows on the ground. Beginners can confuse Gymnopilus with Galerina , which contains deadly poisonous species.

Taxonomy

Gymnopilus was formerly divided among Pholiota and the defunct genus Flammula. The genus has over 200 species worldwide. [2]

Psychoactive species

Fourteen members of Gymnopilus contain psilocybin, [3] although their bitter taste often deters recreational users. These species include G. aeruginosus , G. braendlei , G. cyanopalmicola , [4] G. dilepis , [5] G. intermedius , G. junonius , G. luteofolius , G. luteoviridis , G. luteus , G. purpuratus , [4] G. subearlei , [4] G. subpurpuratus , [4] G. validipes and G. viridans . [6] Subspecies of G. junonius from Japan are reported to contain psilocybin, while some western North American members do not. [7]

Several species of Gymnopilus contain bis-noryangonin [4-hydroxy-6-(4-hydrostyryl)-2-pyrone] and hispidine [4-hydroxy-6-(3,4-dihydroxystyryl)-2-pyrone], which are closely related to the alpha-pyrones found in kava. [8]

Phylogeny

A 2003 phylogenetics study identified five well-supported clades within Gymnopilus: [2]

  1. the spectabilis-imperialis group
  2. nevadensis-penetrans group
  3. a clade formed by G. underwoodii, G. validipes and G. cf. flavidellus
  4. aeruginosus-luteofolius group
  5. lepidotus-subearlei group

Although the genus Gymnopilus was found to be monophyletic, the phylogenetically related groups do not support the traditional infrageneric classifications based on morphology.

Etymology

The name means naked pileus .

Habitat

Most members of Gymnopilus grow on wood but at times may appear terrestrial if the wood is buried or decomposed.

<i>Psilocybe</i> Genus of fungi

Psilocybe is a genus of gilled mushrooms, growing worldwide, in the family Hymenogastraceae. Many species contain the psychedelic compounds psilocybin and psilocin.

<i>Galerina</i> Genus of saprobic fungi

Galerina is a genus of small brown-spore saprobic mushroom-bearing fungi, with over 300 species found throughout the world from the far north to remote Macquarie Island in the Southern Ocean. The genus is most noted for some extremely poisonous species which are occasionally confused with hallucinogenic species of Psilocybe. Galerina mushrooms are typically small and hygrophanous, with a slender and brittle stem. They are often found growing on wood, and when on the ground have a preference for mossy habitats.

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

The Strophariaceae are a family of fungi in the order Agaricales. Under an older classification, the family covered 18 genera and 1316 species. The species of Strophariaceae have red-brown to dark brown spore prints, while the spores themselves are smooth and have an apical germ pore. These agarics are also characterized by having a cutis-type pileipellis. Ecologically, all species in this group are saprotrophs, growing on various kinds of decaying organic matter. The family was circumscribed in 1946 by mycologists Rolf Singer and Alexander H. Smith.

<i>Gymnopilus junonius</i> Species of fungus

Gymnopilus junonius is a type of mushroom-forming fungus in the family Hymenogastraceae. Commonly known as the spectacular rustgill, this large orange mushroom is typically found growing on tree stumps, logs, or tree bases. Some subspecies of this mushroom contain the neurotoxic oligoisoprenoid gymnopilin.

<i>Gymnopilus luteofolius</i> Species of fungus

Gymnopilus luteofolius, known as the yellow-gilled gymnopilus, is a large and widely distributed mushroom that grows in dense clusters on dead hardwoods and conifers. It grows in late July to November in the east and in the winter on the west coast of North America. It has a rusty orange spore print and a bitter taste.

It is widely distributed and common in the Pacific Northwest. It has a rusty orange spore print and a bitter taste and contains the psychedelic chemical psilocybin. It was given its current name by mycologist Rolf Singer in 1951.

<i>Gymnopilus purpuratus</i> Species of agaric fungus in the family Hymenogastraceae

Gymnopilus purpuratus is a species of agaric fungus in the family Hymenogastraceae. It grows in clusters on dead wood, tree stumps and wood chip mulch. It is widely distributed and has been recorded in Argentina, Australia, Chile, New Zealand, the UK and Germany. It has a broadly convex cap covered in small dry reddish-brown scales, a stout yellow stem beneath reddish brown, wine-red to purple vertical fibres, and a thick rusty orange spore print.

<i>Gymnopilus sapineus</i> Species of fungus

Gymnopilus sapineus, commonly known as the scaly rustgill or common and boring gymnopilus, is a small and widely distributed mushroom which grows in dense clusters on dead conifer wood. It has a rusty orange spore print and a bitter taste. This species does not stain blue and lacks the hallucinogen psilocybin.

In South America, it has been recorded from Bolivia, Colombia, and Ecuador. It is also known from the Caribbean island Martinique, and China. The mushroom grows in clusters or groups on rotting wood. The fruit bodies have conical to bell-shaped reddish- to orangish-brown caps that are up to 2.5 cm (1.0 in) in diameter, set atop slender stems 3 to 5 cm long. The mushrooms stain blue when bruised, indicative of the presence of the compound psilocybin. Psilocybe yungensis is used by Mazatec Indians in the Mexican State of Oaxaca for entheogenic purposes.

<i>Gymnopilus maritimus</i> Species of fungus

Gymnopilus maritimus is a fungus species of the family Hymenogastraceae first collected in northern Sardinia, Italy, in 2006. The species produces moderately sized, sturdy mushrooms of a reddish-orange colour. The cap, which can measure up to 70 millimetres (3 in) across, is covered in orange fibrils, and sometimes has small scales. The yellowish stem measures up to 110 mm (4 in) in length by 8 mm (0.3 in) in width, and sometimes shows remnants of the partial veil. The mushrooms have thick gills of a variable colour, ranging from yellow to rust but staining darker, and the yellow flesh has a mild taste. The mushrooms leave a rusty-brown spore print, while the spores themselves measure from 7.5–11.5 micrometres (0.00030–0.00045 in) in length. The species is most similar in appearance to G. arenophilus and G. fulgens, but can be differentiated from both morphologically. Despite the similarities, it is not closely related to either, suggesting convergent evolution. Instead, within the genus Gymnopilus, it is most closely related to the spectabilis–imperialis clade. However, it is not particularly similar to any of its closest relatives.
