Do Conocybe species contain psilocybin?

Some Conocybe species have historically been reported to contain trace amounts of psilocybin, but the genus is predominantly known for containing highly toxic species. The genus Conocybe is considered dangerous and should be approached with extreme caution.

Where do Conocybe species grow naturally?

Conocybe species grow in a wide range of habitats including lawns, meadows, dung, and wood chip areas. They are found worldwide in temperate and tropical climates.

Are Conocybe species dangerous?

Yes, many Conocybe species are extremely dangerous. Conocybe filaris, for example, contains lethal amatoxins identical to those in the death cap mushroom. This genus should never be consumed without absolute expert-level certainty of identification.

What are the key identifying features of Conocybe species?

Conocybe species typically have small, slender fruiting bodies with a conical to bell-shaped cap, a thin fragile stem, and rust-brown to cinnamon-brown spore prints. They closely resemble other toxic genera. Always consult an expert before handling.

What is the harm-reduction advice regarding Conocybe species?

For harm reduction: avoid consuming any Conocybe species unless you have expert-level mycological training. The risk of confusing toxic amatoxin-containing Conocybe with any psilocybin-containing mushroom is extremely high and potentially lethal.

Active Conocybe Species Guide

⚠️ CRITICAL WARNING

Do NOT attempt to forage Conocybe species. The genus contains deadly toxic species that are nearly identical to the rare active ones. Even experienced mycologists avoid Conocybe. This guide is for educational purposes only.

The Conocybe Genus

The genus Conocybe contains over 200 species of small, fragile, "LBM" (Little Brown Mushrooms). Only a handful contain psilocybin—and many others contain deadly amatoxins (the same toxins that make Amanita phalloides lethal).

Known Active Species

1. Conocybe cyanopus

Identification

Cap: 1-3 cm, conical to bell-shaped, tan to cinnamon-brown, hygrophanous
Stem: 4-8 cm, thin, fragile, white to pale, bruises blue
Gills: Brown, attached
Spore Print: Rusty brown
Habitat: Lawns, grassy areas, dung-enriched soil

Potency

Psilocybin: 0.3-0.6% (moderate)

2. Conocybe smithii

Identification

Cap: 0.5-2 cm, conical, pale tan to ochre
Stem: Very thin, fragile, bruises blue weakly
Habitat: Dung, enriched lawns

Potency

Psilocybin: 0.1-0.4% (low to moderate)

3. Conocybe siligineoides

Identification

Cap: 1-2.5 cm, conical, yellow-brown
Stem: Thin, white, may bruise blue
Habitat: Grassy areas, wood chips

Potency

Psilocybin: 0.2-0.5% (low to moderate)

Why Conocybe is NOT Worth Foraging

Reason 1: Deadly Lookalikes

Several Conocybe species contain amatoxins—the same toxins in the Death Cap mushroom. These include:

Conocybe filaris (DEADLY)
Conocybe rugosa (TOXIC)
Conocybe lactea (TOXIC)

The problem: Active and toxic Conocybe species are nearly indistinguishable in the field. Even spore prints are similar.

Reason 2: Low Potency

Even if you correctly identify an active species, the psilocybin content is LOW compared to Psilocybe cubensis or semilanceata. The risk-to-reward ratio is terrible.

Reason 3: Fragility

Conocybe mushrooms are extremely fragile and decompose within hours of picking. They're difficult to transport and preserve.

How to Distinguish Active vs Toxic Conocybe

Short answer: You can't reliably.

Some guides suggest checking for:

Blue bruising (active species only)
Spore color (active species have rusty-brown spores)
Habitat (active species prefer dung-enriched areas)

However: These features overlap significantly, and misidentification can be fatal. Amateur foragers should NEVER consume Conocybe mushrooms.

Comparison: Active vs Toxic Conocybe

Feature	Active Species	Toxic Species
Bruising	Weak to moderate blue	No bruising
Habitat	Dung, enriched lawns	Lawns, wood chips, forests
Spore Print	Rusty brown	Rusty brown (SAME!)
Cap Color	Tan to brown	Tan to brown (SAME!)
Toxicity	None (psilocybin only)	Amatoxins (LETHAL)

☠️ Amatoxin Poisoning

Symptoms appear 6-24 hours after ingestion:

Severe vomiting and diarrhea
Abdominal pain
Liver and kidney failure (irreversible)
Death within 1-2 weeks without treatment

There is no antidote. Treatment is supportive care and liver transplant.

Safer Alternatives

If you're interested in psilocybin mushrooms, focus on these much safer options:

Psilocybe cubensis (easy to cultivate, widely available)
Psilocybe semilanceata (distinctive features, no deadly lookalikes)
Psilocybe cyanescens (wavy cap makes it recognizable)

Final Recommendation

Do not forage Conocybe species. The risk of fatal misidentification is too high. If you're absolutely determined to study them, work with a professional mycologist and use DNA sequencing for positive ID.
