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.

Suillus cavipes, commonly known as the hollow foot is a species of mushroom in the genus Suillus. The epithet cavipes (Latin: 'hollow foot') refers to the hollow stem. The brownish cap is up to 12 centimetres (4+3⁄4 in) wide, dry, fibrillose, sometimes with veil remnants on the edge. The pores are buff and usually decurrent. The stipe is up to 9 cm long and 2 cm thick, yellowish above, sometimes with a slight ring, and cap-colored below. The flesh is whitish and firm. It is found in Europe and North America. It is associated with larch in the Pacific Northwest. It is edible.

Kuehneromyces is a genus of agaric fungi in the family Strophariaceae. The genus was circumscribed by mycologists Rolf Singer and Alexander H. Smith in 1946. The genus name of Kuehneromyces is in honour of Robert Kühner (1903–1996), who was a French mycologist most notable for reviewing many agaric. The best known species in the genus is K. mutabilis, the sheathed woodtuft, which – despite closely resembling the deadly galerina, Galerina marginata, – is a popular edible mushroom in Europe that can also be cultivated on wood.

Suillus lakei, commonly known as the matte Jack, Lake's bolete, or the western painted Suillus, is a species of fungus in the family Suillaceae. It is characterized by the distinctive reddish-brown tufted fibers or small scales on the cap, and the presence of a woolly veil on the stem. The caps can reach diameters of up to 15 cm (6 in), while the stems are between 6 and 12 cm (2+1⁄4 and 4+3⁄4 in) long and usually 1–3 cm (1⁄2–1+1⁄4 in) thick. On the underside of the cap is a layer of spongy yellow to yellow-brown angular pores; these pores are covered with a whitish partial veil when young. A

Zelleromyces is a genus of fungi in the family Russulaceae. It was first described by mycologists Rolf Singer and Alexander H. Smith in 1960 to contain hypogeous (underground) fungi with gasteroid fruit bodies that "bleed" latex when they are cut. The genus was circumscribed in Mem. Torrey Bot. Club vol.21 (3) on page 18 in 1960. The genus name of Zelleromyces is in honour of Sanford Myron Zeller (1885–1948), who was an American mycologist. Phylogenetic analyses show that Zelleromyces species fall into the genus Lactarius. Nevertheless, the genus name is still in use and has not been formally

It is an orangish species with a smooth cap 3–9 centimetres (1+1⁄4–3+1⁄2 in) in width. The stalk is 4–15 cm (1+1⁄2–6 in) long. It is found in North America and Australia. It grows in groups on decaying wood.

Mycena overholtsii, commonly known as the snowbank fairy helmet or fuzzy foot, is a species of fungus in the family Mycenaceae. The mushrooms produced by the fungus are relatively large for the genus Mycena, with convex grayish caps up to 5 cm (2 in) in diameter and stems up to 15 cm (6 in) long. The gills on the underside of the cap are whitish to pale gray, and initially closely spaced before becoming well-spaced at maturity after the cap enlarges. The mushrooms are characterized by the dense covering of white "hairs" on the base of the stem. M. overholtsii is an example of a snowbank

Rhizopogon vinicolor is a species complex of ectomycorrhizal fungus which forms a mutualistic relationship with the Douglas-fir (Pseudotsuga spp.). The species was first described scientifically by American mycologist Alexander H. Smith in 1966.

Psilocybe strictipes is a mushroom that grows on grassy meadows and lawns; It is found throughout the cool temperate and subarctic regions of the Northern Hemisphere and it is most common in Europe, and the Pacific Northwest region of North America. It contains the psychoactive compound psilocybin is closely related to Psilocybe semilanceata and Psilocybe pelliculosa. Psilocybe strictipes is commonly confused with Psilocybe semilanceata and can be differentiated by its lack of a papilla and a convex to subumbonate cap. "Strictipes" comes from the Latin words stricti (narrow) and pes (foot).

Psilocybe baeocystis is a psilocybin mushroom of the family Hymenogastraceae. It contains the hallucinogenic compounds psilocybin, psilocin and baeocystin. The species is commonly known by various names such as bottle caps, knobby tops, blue bells, olive caps, blue Meanies.

Boletus barrowsii, also known in English as the white king bolete after its pale colored cap, is a species of fungus in the genus Boletus. It was formerly considered a color variant of B. edulis.

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. Psilocybe pelliculosa is found in the Pacific Northwest region of the United States and Canada, where it grows on the ground in
