Panaeolus africanus is a little brown mushroom that contains irregular amounts of the hallucinogens psilocybin and psilocin. It has been found in central Africa and southern Sudan.
Panaeolus olivaceus is a widely distributed, seldom identified, little brown mushroom that contains the hallucinogen psilocybin; it is often mistaken for Panaeolina foenisecii and is distinguished by its black spore print and darker gill coloration when mature alongside a slightly thicker stem. It is even more easily mistaken for Panaeolus cinctulus or Panaeolus fimicola and can be distinguished from them both by its slightly roughened spores. It is also easily confused with Panaeolina castaneifolia, a species which has spores that are dark brown and significantly more roughened.

Inocybe tricolor is a rare member of the genus Inocybe that is widely distributed in temperate forests. It is a small mycorrhizal mushroom that contains the hallucinogens psilocybin and psilocin. Inocybe tricolor is found under Norway spruce in central Europe.
Gymnopilus aeruginosus, also known as the Magic Blue Gym, is a mushroom which grows in clusters on dead wood and wood chip mulch. It is widely distributed and common in the Pacific Northwest. It has a rusty orange spore print and a bitter taste and contains the hallucinogen psilocybin. It was given its current name by mycologist Rolf Singer in 1951.
Psilocybe strictipes is a psilocybin 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 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).

Inocybe lacera is a poisonous species of mushroom in the genus Inocybe. Its appearance is that of a typical "little brown mushroom": small, brown and indistinct. However, it is distinguishable by its microscopic features, particularly its long, smooth spores. As with many other species of Inocybe, I. lacera contains the poisonous chemical muscarine which, if consumed, can lead to salivation, lacrimation, urination, defecation, gastrointestinal problems and emesis. Found in Europe and North America, it typically grows in autumn in mixed woods, favouring sandy soil. There are several documented subspecies in addition to the main I. lacera var lacera, including the dwarf form I. lacera var. subsquarrosa and I. lacera var. heterosperma, found in North America.
Psilocybe aztecorum is a species of psilocybin mushroom in the family Hymenogastraceae. Known from Arizona, Colorado, central Mexico, India and Costa Rica, the fungus grows on decomposing woody debris and is found in mountainous areas at elevations of 2,000 to 4,000 m, typically in meadows or open, grassy conifer forests. The mushrooms have convex to bell-shaped caps 1.5–2 cm (0.6–0.8 in) in diameter, atop slender cylindrical stems that are up to 7.5 cm (3.0 in) long. The color of the caps changes with variations in hydration, ranging from dark chestnut brown to straw yellow or whitish when dry. The base of the stem is densely covered with conspicuous white rhizomorphs, a characteristic uncommon amongst Psilocybe species.
Inocybe godeyi is a species of Inocybaceae fungus found in Europe. The species produces mushrooms with cone-shaped caps up to 5 cm (2 in) in diameter. The caps are cream, becoming browner, but they bruise red. The stem is up to 6 cm (2 in) long, and has a "bulb" at the base. The white flesh has a strong smell and an acrid taste. The mushrooms can be found on forest floors in autumn months; the species forms an ectomycorrhizal relationship to surrounding trees, favouring beech. I. godeyi is known to be poisonous, containing muscarine compounds, and consumption of the mushrooms can lead to SLUDGE syndrome. The species is sometimes mistaken for the deadly I. erubescens.
Psilocybe washingtonensis is a species of psilocybin mushroom in the family Hymenogastraceae. It is similar in appearance to Psilocybe pelliculosa and P. silvatica, and a microscope is needed to reliably distinguish between them.
