<span class="mw-page-title-main">Secotioid</span> Type of fungi

Secotioid fungi are an intermediate growth form between mushroom-like hymenomycetes and closed bag-shaped gasteromycetes, where an evolutionary process of gasteromycetation has started but not run to completion. Secotioid fungi may or may not have opening caps, but in any case they often lack the vertical geotropic orientation of the hymenophore needed to allow the spores to be dispersed by wind, and the basidiospores are not forcibly discharged or otherwise prevented from being dispersed —note—some mycologists do not consider a species to be secotioid unless it has lost ballistospory.

<span class="mw-page-title-main">Agaricales</span> Order of mushrooms

The fungal order Agaricales, also known as gilled mushrooms or euagarics, contains some of the most familiar types of mushrooms. The order has 33 extant families, 413 genera, and over 13,000 described species, along with six extinct genera known only from the fossil record. They range from the ubiquitous common mushroom to the deadly destroying angel and the hallucinogenic fly agaric to the bioluminescent jack-o-lantern mushroom.

<i>Psilocybe</i> Genus of fungi

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

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

Galerina is a genus of small brown-spore saprobic 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. Species 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>Galerina vittiformis</i> Species of fungus

Galerina vittiformis is a species of agaric fungus in the family Hymenogastraceae, and the type species of the genus Galerina. It is widely distributed in temperate regions, where it typically grows in moist locations, often among mosses. The fungus has been shown to bioaccumulate various heavy metal from contaminated soil.

<i>Galerina marginata</i> Poisonous fungus in the family Hymenogastraceae

Galerina marginata, known colloquially as funeral bell, deadly skullcap, autumn skullcap or deadly galerina, is a species of extremely poisonous mushroom-forming fungus in the family Hymenogastraceae of the order Agaricales. It contains the same deadly amatoxins found in the death cap. Ingestion in toxic amounts causes severe liver damage with vomiting, diarrhea, hypothermia, and eventual death if not treated rapidly. About ten poisonings have been attributed to the species now grouped as G. marginata over the last century.

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

The Hymenogastraceae is a family of fungi in the order Agaricales with both agaric and false-truffle shaped fruitbodies. Formerly, prior to molecular analyses, the family was restricted to the false-truffle genera. The mushroom genus Psilocybe in the Hymenogastraceae is now restricted to the hallucinogenic species while nonhallucinogenic former species are largely in the genus Deconica classified in the Strophariaceae.

<i>Deconica montana</i> Species of fungus

Deconica montana, commonly known as the mountain moss Psilocybe, is a common species of mushroom that usually grows in mossy and montane regions around the world. The appearance is that of a typical "little brown mushroom" with a small, brown cap and a straight, thin stipe.

Alexander Hanchett Smith was an American mycologist known for his extensive contributions to the taxonomy and phylogeny of the higher fungi, especially the agarics.

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

The Physalacriaceae are a family of fungi in the order Agaricales. Species in the family have a widespread distribution, ranging from the Arctic, (Rhizomarasmius), to the tropics, e.g. Gloiocephala, and from marine sites (Mycaureola) and fresh waters (Gloiocephala) to semiarid forests (Xerula).

<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>Mycena leptocephala</i> Species of fungus

Mycena leptocephala, commonly known as the nitrous bonnet, is a species of fungus in the family Mycenaceae. The mushrooms have conical grayish caps that reach up to 3 cm (1.2 in) in diameter, and thin fragile stems up to 5 cm (2.0 in) long. The gills are gray and distantly spaced. The spores are elliptical, typically measure 7–10 by 4–6 μm, and are white in deposit. When viewed under a light microscope, the gills have abundant spindle-shaped cystidia on the gill edges, but few on the gill faces. The mushroom is found in North America, Asia, and Europe where it grows singly or in groups on conifer needles, cones and sticks on the forest floor. It has a distinctive odor of bleach; the edibility is unknown. Similar species include Mycena alcalina, M. austera, and M. brevipes.

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

Psilocybe pelliculosa is a species of fungus in the family Hymenogastraceae. The fruit bodies, or mushrooms, have a conical brownish cap up to 2 cm in diameter atop a slender stem up to 8 cm long. It has a white partial veil that does not leave a ring on the stem. American mycologist Alexander H. Smith first described the species in 1937 as a member of the genus known today as Psathyrella; it was transferred to Psilocybe by Rolf Singer in 1958.

<i>Hemipholiota</i> Genus of fungi

Hemipholiota is a genus of agaric fungi in the order Agaricales. It was originally proposed by Rolf Singer in 1962 as a subgenus of Pholiota to contain species with absent or sparse pleurocystidia and absent chrysocystidia. Henri Romagnesi raised it to generic status in 1980, but this naming was invalid as it did not meet the requirements of the International Code of Nomenclature for algae, fungi, and plants. Marcel Bon published the genus validly in 1986.

<i>Mycena guldeniana</i> Species of fungus

Mycena guldeniana is a species of agaric fungus in the family Mycenaceae. Described as new to science in 2011, it occurs in Norway. The specific epithet guldeniana honors Norwegian mycologist Gro Gulden. The whitish caps of the fruit bodies are hemispherical before flattening out, and measure 1–2 mm in diameter. They appear solitarily or in small groups on the fallen leaves of Salix species. The spores are broadly ellipsoid to pip-shaped, smooth, amyloid, and measure 7.5–8.7–10 by 4.8–5.5–6.5 µm.

Stagnicola is an agaric fungal genus that contains the single species Stagnicola perplexa. This fungus colonizes plant debris in wet coniferous forest floor depressions and shallow pools, and fruits after the pools drain or dry in late summer to early fall in North America and Europe. The genus is characterized by smooth, yellowish brown basidiospores lacking a germ pore, and a naucorioid appearance, with brownish mycelium at the base of the stems. Phylogenetically, Stagnicola appeared rather isolated and proved to be closest to Mythicomyces and Mythicomyces was closest to the Psathyrellaceae. In 2019 the two genera were shown to be closely related and placed in a new family, Mythicomycetaceae sister to the Psathyrellaceae.

Flammula is a dark brown-spored genus of mushrooms that cause a decay of trees, on whose bases they often fruit, forming clusters of yellowish brown mushrooms.

Phaeogalera is a small genus of slender, fleshy bog and swamp-inhabiting mushrooms with large, brownish spores with a germ pore and a hymenium lacking chrysocystidia. Phaeogalera resemble Galerina in their habitat, macroscopic appearance, and spore print color, however, their microscopic characteristics more closely resemble Psilocybe. The type species, Phaeogalera stagnina, has an Arctic-alpine distribution in the Northern Hemisphere extending into the boreal forests and taiga. It grows along the edges of bogs in peaty soils and sometimes amongst Sphagnum or other mosses. This type species has been classified in Galerina, Tubaria and Psilocybe. Modern molecular evidence supports the recognition of Phaeogalera as an independent genus separate from Galerina. The generic name is built upon the antiquated generic name "Galera", now synonymous with Galerina, and with a reference to the darker colors of the basidiospores of Phaeogalera. When originally proposed by Kühner, he forgot to fully cite the original publication for the type species which explains by the name was later validly published by Pegler & Young in 1975. The genus Meottomyces was segregated from Phaeogalera after briefly being classified together by Romagnesi.

<i>Rhizomarasmius epidryas</i> Species of fungus

Rhizomarasmius 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.
