The short answer
Besides Psilocybe cubensis, vendors on Culture Cave list well over a dozen other Psilocybe species, from the Mexican species described in the 1950s to species named in the last few years. Nearly all share the dark purple-brown spore print of the genus, so print colour will not separate them; range, habitat and microscopic detail (spore shape and size, cystidia) do. Most are sold as prints and swabs because most of the material is a specific wild or locality collection rather than a long-domesticated line.
Why these come as prints and swabs, not syringes
A cubensis strain has usually been kept in culture for years, so a vendor can make syringes from it on demand. Exotic species tend to arrive differently: a collector finds a patch in the wild, takes prints or swabs from those few mushrooms, and that small, finite batch is what gets listed. Dinospores, which carries the widest range here, attaches an iNaturalist observation number to many of its wild prints, so you can look up the field photographs of the collection your spores came from. For taxonomy that matters: the print is tied to a public, photographed record.
Dry spores also keep far better than a hydrated suspension, and a print shows you the spore colour directly. The trade-off is cleanliness: wild material brings bacteria, mould and debris from the field, and Dinospores notes on its wild listings that dilution is recommended when observing wild-collected spores. Where a syringe does exist, it is nearly always an isolated syringe from a collection the vendor has already worked in the lab. The guides to prints and swabs and to isolated versus multispore syringes explain the formats.
Mexico and Central America
Psilocybe zapotecorum is the type species of its section, described by Roger Heim in the 1950s from Oaxaca and named after the Zapotec people. It is a medium to large, strongly blue-bruising mushroom of humid, mossy ground in subtropical and cloud forest from southern Mexico into Central and South America, with a dark purple-brown print. Dinospores lists the most collections: Cinco Palos, La Martinica, Popocatépetl Volcano and Texolo as swabs, prints or isolated syringes, a wild Citalapa print from Veracruz, and the locality cross Encinal 2 x Cinco Palos. Sporeworks and Fungus Frequency list unnamed isolates and plates.
Psilocybe mexicana is a small, conical grassland species of Mexico and Central America, described by Heim in the 1950s, and one of the species that forms sclerotia (hard resting bodies) as well as mushrooms. Its print is dark purple-brown. Sporeworks lists Strain-A, which it says was found in pastureland near the Colima volcano; Dinospores lists Strain X, which it traces to a Sporeworks collection made in Xico, Veracruz, and a wild Citalapa print.
Psilocybe tampanensis is a close relative of mexicana that also forms sclerotia. It was described from a single mushroom found in sandy ground near Tampa, Florida, and few wild finds have been reported since. Sporeworks says its Pollock print and isolate descend directly from that original collection. Dinospores lists ATL 7, Lexington, Gold Spore, which the vendor says drops golden spores, a trait it describes as a first for the species, and Mex A, once sold as mexicana until ITS sequencing matched it to tampanensis.
Psilocybe caerulescens is the "derrumbe" or landslide mushroom, found in groups on disturbed, muddy, clay-rich ground with woody debris from the southern United States through Mexico into South America. It is a fairly robust species with a dark purple-brown print. Dinospores lists La Montaña and its brother culture Cinco Palos, both from Veracruz, South Carolina, CAGA (short for Caerulescens Georgia) and a stocky Low Spore form with a reduced spore load on the gills.
Psilocybe subtropicalis is a species of subtropical Mexico with a tangled naming history: Dinospores notes it has synonymous names, and Sporeworks files its swab as "P. subtropicalis (P. semperviva)". The collections are the wild Tres Soles swab from Veracruz, the old hoogshagenii var. convexa lineage, the locality cross HVC x Tres Soles made from both, and semperviva swabs from both vendors.
Psilocybe muliercula, whose name means "little woman", is a slender species of the high pine and fir forests of central Mexico. Dinospores lists a single wild Acajete print from Veracruz.
The Pacific Northwest wood-lovers
Psilocybe cyanescens is known as the "wavy cap" for the rippled margin of its caramel cap. It is a wood-loving species of wood chips and woody debris in the Pacific Northwest, and is also well established in western Europe, Britain included, and New Zealand. Dinospores lists wild Coventry (England), Irvington (Portland) and Tillamook Bay collections, and Sporeworks, Kaiju Cultures and Sonoran Spores list it in other formats. Despite the shared name it is unrelated to Panaeolus cyanescens; the Pan Cyan guide explains.
Psilocybe azurescens is a larger relative with a small coastal range around the mouth of the Columbia River in Oregon and Washington, where it is found on woody debris and among dune grasses. Its caramel caps bruise a deep blue, and its print is dark purple-brown to black. Dinospores lists two wild Oregon collections, Fort Stevens and Fort Stevens Maestro.
Psilocybe allenii was described in 2012 from the Pacific coast of North America, a close relative of cyanescens found on wood chips in urban landscaping. Dinospores lists the wild Duniway collection from Oregon and the lab-kept Oregon Coast print.
Psilocybe baeocystis is a small Pacific Northwest species of mulch, wood chips and lawns with woody debris, with an olive-brown cap that dries much paler. Dinospores lists its wild WA Coast collection as a print and a swab set.
Psilocybe stuntzii, the "blue ringer", is a Pacific Northwest species of wood chips and newly laid lawns, recognised by a membranous ring on the stem that often stains blue. Dinospores lists a wild WA Coast print and Orini, a New Zealand collection it labels "cf. stuntzii", meaning compare with stuntzii.
Grassland, eastern and southern species
Psilocybe semilanceata, the liberty cap, is the classic grassland species of temperate Europe, the UK included, and of the Pacific Northwest. It is found among grass roots in grazed pasture rather than on dung itself, and has a sharply pointed, bell-shaped cap. Nearly all material in circulation is wild-collected, and Dinospores lists two such prints, Astoria from Oregon and Coventry from the UK.
Psilocybe ovoideocystidiata was described in 2007 from the eastern United States and is named for a microscopic feature, its egg-shaped (ovoid) cystidia, which makes it a good species to study on a slide. It is found on woody debris along rivers and streams and carries a membranous ring. Dinospores lists the wild Zanesville print from Ohio, and Fungus Frequency a research plate.
Psilocybe weilii is a Georgia species described in the 1990s from red clay soil under pine and sweetgum. Fungus Frequency lists a Georgia research plate.
Psilocybe niveotropicalis is a recently described, warm-climate, wood-loving species from Florida. Dinospores lists a Vero Beach swab set and a Jupiter isolated syringe, both from Florida collections.
Psilocybe ingeli is the newest species here, described in 2024 from the Ingeli mountains of KwaZulu-Natal in South Africa. Sporeworks says all current samples descend from a single 2023 collection, and describes a caramel-brown cap fading to light grey, slight blue bruising at the margin and a dark purple-brown print. Dinospores, Fungus Frequency, Sporeworks and TecheGenetics all list it; the natalensis post covers the other South African species.
Reading an exotic listing
Three details are worth checking. First, wild or lab-kept: a wild print is closer to the species as found, a lab-kept line usually gives a cleaner slide. Second, "cf." (compare with) and "aff." (has affinity with) mean the collector is not certain of the species, and some lines, like Mex A, have been renamed after sequencing. Third, a collection name is a place, not a trait, so Cinco Palos zapotecorum and Cinco Palos caerulescens are two species sharing a locality name.
Psilocybe and Panaeolus spores and cultures on Culture Cave are sold for microscopy and taxonomy use only, and buyers must know their local law before ordering; see the guides on whether mushroom spores are legal in the UK and in the USA.
