Suillus grevillei, commonly known as tamarack jack, Greville's bolete, or larch bolete, is a mycorrhizal mushroom with a tight, brilliantly coloured cap, shiny and wet looking with its mucous slime layer. The hymenium easily separates from the flesh of the cap, with a central stalk that is quite slender. The species has a ring or a tight-fitting annular zone.

Volvariella volvacea (also known as paddy straw mushroom or straw mushroom) is a species of edible mushroom cultivated throughout East and Southeast Asia and used extensively in Asian cuisine. They are often available fresh in regions where they are cultivated, but elsewhere are more frequently found canned or dried. Worldwide, straw mushrooms are the third-most-consumed mushroom.

Matsutake (Japanese: 松茸/マツタケ), Tricholoma matsutake, is a species of mushroom, with a cap that can reach up to 35 centimetres (14 in) wide. It resembles at least one poisonous species. Growing in Eurasia and North America, it is a mycorrhizal species. It is a choice edible mushroom prized in Japanese cuisine for its distinct aroma.

Psilocybe cubensis, commonly known as the magic mushroom, shroom, golden halo, cube, or gold cap, is a species of psilocybin mushroom of moderate potency whose principal active compounds are psilocybin and psilocin. It belongs to the fungus family Hymenogastraceae and was previously known as Stropharia cubensis. It is the best-known psilocybin mushroom due to its wide distribution and ease of cultivation.

The Cortinariaceae are a large family of gilled mushrooms found worldwide, containing over 3200 species. The family takes its name from its largest genus, the varied species of the genus Cortinarius. Many genera formerly in the Cortinariaceae have been placed in various other families, including Hymenogastraceae, Inocybaceae and Bolbitiaceae. The deadly toxin orellanine has been found in at least 34 Cortinariaceae.

Omphalotus olearius, commonly known as the jack-o'-lantern mushroom, is a poisonous orange gilled mushroom that to an untrained eye appears similar to some chanterelles. It is notable for its bioluminescent properties. It is found in woodland areas in Europe, where it grows on decaying stumps, on buried roots or at the base of hardwood trees. A similar, but phylogenetically distinct species found in eastern North America is Omphalotus illudens. Unlike chanterelles, Omphalotus olearius and other Omphalotus species contain the toxin illudin S, and are poisonous to humans. While not typically

Kuehneromyces mutabilis (synonym: Pholiota mutabilis), commonly known as the sheathed woodtuft, is a species of fungus that grows in clumps on dead wood. It is edible but strongly resembles the deadly poisonous Galerina marginata.

Volvariella bombycina, commonly known as the silky volvariella, tree silksheath, silky sheath, silky rosegill, silver-silk straw mushroom, or tree mushroom, is a species of fungus in the family Pluteaceae. The fruit body (mushroom) begins developing in a thin, egg-like sac. This ruptures and the stem expands quickly, leaving the sac at the base of the stem as a volva. The cap, which can attain a diameter of up to 20 centimetres (8 inches), is white to slightly yellowish and covered with silky hairs. On the underside of the cap are closely spaced gills, free from attachment to the stem, and

Macrolepiota is a genus of white spored, gilled mushrooms of the family Agaricaceae. The best-known member is the parasol mushroom (M. procera). The widespread genus contains about 40 species.

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.

Amanita crocea, the saffron ringless amanita, is a species of Amanita widely distributed in Europe. It is edible but not recommended for consumption due to its similarity to poisonous species of the genus.

Macrolepiota mastoidea is a species of mushroom producing fungus in the family Agaricaceae.

Strobilurus esculentus is a very common, edible mushroom of the genus Strobilurus. It can often be found in the spring on and around fallen spruce cones.

Tricholomopsis rutilans, commonly known as plums and custard, or red-haired agaric, is a species of gilled mushroom found across Europe and North America.

The Bolbitiaceae are a family of mushroom-forming basidiomycete fungi. A 2008 estimate placed 17 genera and 287 species in the family. Bolbitiaceae was circumscribed by mycologist Rolf Singer in 1948.

Pseudoclitocybe cyathiformis, commonly known as the goblet funnel cap, is a species of fungus and the type species of the genus Pseudoclitocybe. It is found in North America and Europe.

Lyophyllum decastes is a species of fungus in the family Lyophyllaceae. It is known as the clustered domecap in the United Kingdom and the fried chicken mushroom in North America. The basidiocarps (fruit bodies) are agaricoid (gilled mushrooms). It forms large clusters on the ground. Considered edible, it is cultivated in Asia.

Leccinum duriusculum is a bolete mushroom in the genus Leccinum. Originally called Boletus duriusculus by Hungarian–Croatian mycologist Stephan Schulzer von Müggenburg in 1874, it was transferred to Leccinum by Rolf Singer in 1947.

Pleurocybella porrigens, also known as the angel wing, is a species of fungus in the family Phyllotopsidaceae. It medium-sized fruit bodies are whitish and fan-shaped. It is a wood-decay fungus on conifer wood and is widespread in temperate forests of the Northern Hemisphere.

Baeospora myosura, commonly known as conifercone cap, is a species of fungus that produces agaricoid fruit bodies. The cap is convex before flattening, 2 centimetres (3⁄4 in) wide, and coloured pale brown to cream. The lamellae are adnexed, pale, and very close. The spore print is white to cream and amyloid. The mushroom grows on decaying conifer cones and is common in North America and Europe. It is nonpoisonous but of unknown edibility.

Strobilurus is a genus of fungi in the family Physalacriaceae. The genus has a widespread distribution in temperate regions, and contains 10 species. Species of Strobilurus grow on pine cones.

Pleurotus citrinopileatus, the golden oyster mushroom (tamogitake in Japanese), is a species of gilled fungus. Native to eastern Russia, northern China, and Japan, the species produces an edible mushroom.

Leucocoprinus birnbaumii, commonly known as the flower pot parasol, yellow parasol, flowerpot parasol, or plantpot dapperling, is a species of gilled mushroom in the family Agaricaceae. It is common in the tropics and subtropics. In temperate regions, it frequently occurs in greenhouses, flowerpots, and indoor terrariums. It is toxic if ingested.

Tricholomopsis decora, commonly known as prunes and custard, is a species of gilled mushroom in the genus Tricholomopsis. It occurs in North America and Britain.

Leucoagaricus is a genus of mushroom-forming fungi in the family Agaricaceae. As of March 2023 there are over 200 accepted species of Leucoagaricus with ongoing research into the genus adding several more each year. Leucocoprinus is a similar genus and considered by some sources to be indistinct from Leucoagaricus based on genetic data that demonstrates they are monophyletic. Species are separated into these genera based on macroscopic features such as cap striations in Leucocoprinus or the more persistent basidiocarps (mushrooms) of Leucoagaricus as well as microscopic features such as the

Collybia sordida, formerly Lepista sordida, is a species of blewit mushroom found across the Northern Hemisphere. It is known to form fairy rings.

Catathelasma imperiale, also known as Catathelasma imperialis, and commonly known as the imperial mushroom, Hutsul mushroom, or korban, is a species of agaric (gilled mushroom) in the family Biannulariaceae. Basidiocarps (fruit bodies) are stocky, with a double annulus (ring), and a tapering to rooting stipe (stem). The species is ectomycorrhizal with conifers and is found in continental Europe and Asia. Reports from North America are unconfirmed and may refer to Catathelasma evanescens or similar species. The fruit bodies are edible and collected for food in China and elsewhere. The species
