The complete database record: 3 documented constituents, 2 pharmacological actions, 2 traditional / indicated uses, with 21 cited sources.

Botanical Description

Saprotrophic fungus (not a true plant, Hymenogastraceae) with a cap 2-8 cm across, convex to bell-shaped, golden-brown to caramel with a paler margin, fading as it dries. The whitish to yellowish stem often bears a thin ring (annulus) that darkens purple-black from falling spores; gills are grey to dark purple-brown, crowded and adnate. The mycelium colonises dung and dung-enriched, nutrient-rich soil. All parts stain blue-green when bruised or handled, from oxidation of psilocin.[10]

Height: Cap 2-8 cm across; stem several cm tall
Habit: Saprotrophic, dung-loving fungus
Leaves: Not applicable (fungus)
Flowers: Not applicable (fungus); reproduces by spores
Stem: Whitish to yellowish, often with a thin ring (annulus) that darkens with spores
Root: Mycelium colonising dung and dung-enriched soil
Fruit: Grey to dark purple-brown gills; bruises blue-green when handled
Flowering Period: Fruiting bodies appear in warm, humid weather, often following rain

Habitat & Distribution

Most common in subtropical and tropical regions of the Americas (and increasingly recorded elsewhere), growing directly on the dung of grazing livestock - particularly cattle - and on dung-enriched pasture soil in warm, humid climates.[9]

Harvesting

Fruiting bodies are picked by hand as caps expand, typically in warm, humid weather following rain; cultivated production uses sterilised grain or dung-based substrate inoculated with mycelium under controlled humidity and temperature.[10]

Parts: Fruiting body (mycelium/whole mushroom)
Season: Warm, humid weather, often following rain

Key Constituents

Psilocybin[1, 3]

The principal prodrug alkaloid, an indole (tryptamine) compound dephosphorylated to psilocin in the body; the primary active constituent driving the psychoactive and clinically studied antidepressant/anxiolytic effects.

Psilocin[1, 2]

The active metabolite of psilocybin, a serotonin (5-HT2A) receptor agonist directly responsible for the psychoactive effect.

Baeocystin and norbaeocystin (minor tryptamine alkaloids)[6]

Minor related tryptamines present alongside psilocybin/psilocin at lower concentrations, of uncertain individual contribution.

Pharmacological Actions

Antidepressant / mood support[5, 11, 12, 13, 14, 16, 17]

Psilocybin-assisted therapy for depression (clinical trials)

Anxiolytic / calming[5, 7, 17]

Traditional Use & History

Psilocybe mushrooms have a documented history of ceremonial and shamanic use in Mesoamerican indigenous traditions, later popularised globally from the mid-20th century onward. Contemporary clinical research on purified psilocybin, the principal active compound, supports use under professional supervision in psilocybin-assisted therapy for depression and anxiety, distinct from unsupervised recreational use.[9]

Preparations

Dried whole mushroom[3, 6]

The traditional and most common form; drying concentrates and stabilises psilocybin/psilocin content.

Purified psilocybin (clinical)[1, 2]

The standardised, purified compound used in modern clinical trials, administered under professional supervision.

Dosage

Purified psilocybin (clinical)[1, 2, 4]

Clinical trials of psilocybin-assisted therapy have used purified, weight-calibrated doses (commonly in the range of 20-25 mg psilocybin) administered once or twice under professional supervision in a controlled clinical setting - fundamentally different from unsupervised recreational dosing. Psilocybin is illegal in most jurisdictions outside approved clinical/research settings and should never be used outside professional supervision. Educational reference only, not a prescription or an endorsement of unsupervised use.

Safety, Cautions & Contraindications

Safety note[16, 17]Caution

Psilocybin is physiologically non-toxic and non-addictive in clinical contexts. Psychological risks include anxiety, paranoia, and triggering of latent psychiatric conditions (contraindicated in personal or family history of psychosis or schizophrenia). Use only in appropriate clinical/ceremonial settings with trained supervision. Illegal in most jurisdictions. Avoid mixing with lithium (seizure risk).

Safety note[16, 17, 18]Info

Duke (2002) does not include a dedicated entry for psilocybin mushrooms (Psilocybe cubensis) in the Handbook of Medicinal Herbs, Second Edition.

Dangerous Lookalikes

Galerina Marginata[19, 20, 21]Fatal
Confused Part: The whole small brown mushroom - cap, ringed stem and gills - especially wood-growing collections. Deadly Galerina grows on the same rotting wood and wood chips as wood-loving Psilocybe.
Confusion Context: Deadly Galerina (funeral bell) is the amatoxin mushroom most often mistaken for hallucinogenic Psilocybe and eaten by accident; the two are small brown ringed mushrooms that grow side by side on rotting wood and bark mulch. Galerina carries the same liver-destroying amatoxins as the death cap - by weight sometimes higher - and poisoning is deceptively delayed (6 to 24 hours), with a false recovery before catastrophic liver failure. Both have a ring on the stem and grow on wood, so the ring and the substrate do NOT tell them apart.
Distinguishing Features: Spore-print colour is the only reliable test, and it needs a print taken at home: deadly Galerina drops a RUSTY, cinnamon-brown print; Psilocybe drops a dark purple-brown to blackish-violet print. A rusty-brown print means it is NOT a Psilocybe - do not eat it., Psilocybe flesh usually bruises blue-green where handled; deadly Galerina does not. This is only a supporting hint - bluing can be faint or absent and must NEVER override a wrong spore print.
Key Test: There is no safe field mark. Take a spore print (gills down on white paper or foil, covered, several hours): a rusty or cinnamon-brown print = deadly Galerina or another amatoxin mushroom - do not eat it. Only a dark purple-brown to violet-black print is consistent with Psilocybe. Do not forage small brown wood-growing mushrooms without an expert mycologist and a spore print - a single wrong cap can cause fatal liver failure.

Harvest Readiness

[15]

Part: fruiting-body
Signals: Harvest as the partial veil under the cap tears (ragged and still hanging), before it fully detaches and the gills blacken with dropping spores - an intact veil means not ready.
Basis: traditional
Source Quote: Intact = not ready. Torn but still hanging in ragged fragments = harvest window open.
Species Confirmed: 1
Notes: Azarius (REF-3321) for Psilocybe cubensis; the partial veil under the cap is the readiness signal - harvest as it tears, before it detaches and spores drop. Single source -> provisional. SAFETY: the deadly Galerina marginata (autumn skullcap) can resemble small brown Psilocybe - confirm identity; see Dangerous Lookalikes.
