Copper Tops (Psilocybe subaeruginosa)
What is Copper Tops? A Complete Overview
Copper Tops, colloquially known for their shiny, caramel-colored caps, are wild-growing psychedelic mushrooms native primarily to Australia and New Zealand. Scientifically classified as Psilocybe subaeruginosa, they are one of the most potent naturally occurring psilocybin fungi in the Southern Hemisphere. Known for their distinct bluish bruising and rust-colored gills, Copper Tops are frequently mistaken for other Psilocybe species due to visual similarities, but can often be distinguished by their gelatinous pellicle on the cap and their preference for wood-based substrates.
The fruiting body features a convex to conical cap that ranges from 1.5 to 5 cm in diameter. With age and humidity, the coppery tone deepens, and the cap becomes hygrophanous, altering color as it dries. Spores are dark purplish-brown, and the mushroom emits a mildly farinaceous scent when freshly harvested. A key identifier is the vivid blue bruising on stems, caps, or any damaged tissue which signals presence of psilocybin.
First described scientifically in the 1920s, Psilocybe subaeruginosa has firmly rooted itself as a culturally significant mushroom, especially in Australia and New Zealand's underground psychedelic history. While not widely cultivated due to its wild habitat association, foragers often seek them out during wet seasons in decaying woodlands. Compared to cultivated strains like Psilocybe cubensis, these are far more potent, making cautious dosage and identification practices essential.
Taxonomic Classification
Origin and Traditional Use of Copper Tops
Copper Tops (Psilocybe subaeruginosa) have a deeply intertwined cultural presence, particularly in Australia and New Zealand. While not referenced in traditional indigenous ceremonies in the same way as Psilocybe mexicana or Psilocybe cubensis are in Central and South American shamanism, Copper Tops have gained contemporary significance due to increasing interest in plant medicine and natural psychedelics across Oceania.
The mushroom's modern usage among Western psychonauts and nature-based spirituality practitioners gained traction starting in the 1970s, following the psychedelic renaissance in the United States and Europe. As psilocybin-containing species became subject to stricter regulation globally, local populations began turning to native varieties, such as Psilocybe subaeruginosa, as safer alternatives to imported or cultivated strains.
By the 1980s and 1990s, Copper Tops had become a staple within Australia's psychedelic subculture. Environmentalists, herbalists, and psychonaut communities began organizing foraging trips during the winter rainy seasons, conducting ceremonies and microdosing sessions in forest clearings. Today, Copper Tops hold a special place in New Age psychedelic exploration in coastal regions like Victoria, Tasmania, and parts of New South Wales.
While shamanic traditions tied to this mushroom are relatively new, contemporary spiritual practices often mirror those of Mesoamerican lineage, incorporating fasting, intention setting, and integration periods following journeys. While more research continues into ecological and spiritual uses of P. subaeruginosa, it is revered for its powerful introspective capability, particularly noted for vivid visuals and strong emotional processing.
How to Cultivate Copper Tops
Difficulty Level: Moderately difficult - considered challenging compared to more commonly grown strains like Psilocybe cubensis due to their specific substrate requirements and sensitivity to environmental conditions.
Substrate Requirements:
- CVG (Coco Coir, Vermiculite, and Gypsum) - recommended for cleaner, odor-free cultivation
- Sterilized milo grain spawn for superior nutrition
- Traditional manure/hay substrates (also suitable)
- All-in-one grow kits available for convenience
Environmental Conditions:
- Colonization Temperature: 68°F to 75°F (20°C–24°C)
- Fruiting Temperature: 50°F to 60°F (10°C–16°C)
- Humidity: 85–95% throughout all stages
- Lighting: Minimal light requirements, natural outdoor conditions preferred
Timeline:
- Colonization: 4–8 weeks depending on conditions
- Fruiting: 4–12 weeks, often seasonal
- Outdoor beds may fruit only once per season
Important Note: Copper Tops are sensitive to climate and often require outdoor bed cultivation in shaded environments. Many growers build layered hardwood mulch beds under trees, with fruiting typically occurring in winter after prolonged rain. Patience is essential as some beds may take a full season to produce mushrooms.
Where Does Copper Tops Typically Grow?
Copper Tops thrive in damp, forested environments where decaying wood is abundant. Native to Australia and New Zealand, they are most commonly found in temperate coastal rainforests, eucalyptus stands, pine plantations, and even suburban parks with well-mulched garden beds. Their ideal ecological niche involves rich, decomposing lignin and cellulose fibers from hardwood species such as eucalyptus or acacia.
The mushrooms fruit most prolifically after extended periods of rainfall. The high humidity levels following seasonal downpours create a perfect microclimate for their mycelium to shift into reproduction mode. Forest litter, including leaves, branches, bark, and buried wood chips, are frequently colonized.
Ideal environmental conditions include:
- Damp, shaded forest environments
- Decomposing hardwood substrates
- High humidity from seasonal rainfall
- Temperate coastal climates
- Elevations typically below 1000 meters
While the natural range includes eastern and southern Australia—particularly Victoria, South Australia, New South Wales, and Tasmania—accidental introduction through mulched wood products has allowed sporadic growth in urban and suburban settings. In New Zealand, they are encountered from Wellington to the South Island's temperate forests. Known fruiting sites include national parks, tree plantations, bush trails, and paths where damp mulch retains moisture for weeks post-precipitation.

Is Copper Tops Edible or Toxic?
Toxicity Information:
While Psilocybe subaeruginosa or Copper Tops are not considered poisonous in the traditional sense, their psychoactive properties present both physiological and psychological risks if misused. High concentrations of psilocybin and psilocin make them among the most potent wild Psilocybe species, and thus, they must be consumed responsibly and in moderate dosage.
Physical Risks:
- Nausea or vomiting (especially if consumed raw)
- Tremors and muscular weakness
- Elevated heart rate and blood pressure
- Anxiety or panic attacks (especially in unfamiliar environments)
Risk of Misidentification:
There are also secondary risks tied to misidentification. Several toxic wood-loving Galerina species (such as Galerina marginata) look strikingly similar to P. subaeruginosa and contain deadly amatoxins. Amateur foragers must exercise extreme caution, and never consume mushrooms unless 100% identification confidence is achieved.
What are the Medicinal Uses for Copper Tops?
Copper Tops (Psilocybe subaeruginosa) carry significant potential in the realm of psychedelic-assisted therapy and modern mental health treatment models. Primary medicinal properties stem from the mushrooms' content of psilocybin and its metabolite, psilocin—both known to act on serotonin 5-HT2A receptors within the brain. Research shows that, under controlled and guided use, these compounds can produce neuroplastic and mood-regulating effects.
Potential Benefits:
- Treatment-Resistant Depression: Emerging studies from Australia and New Zealand demonstrate potential for psilocybin therapy to alleviate symptoms of treatment-resistant depression, PTSD, addiction, and end-of-life anxiety
- Microdosing Applications: Sub-perceptual doses consumed every few days have been explored to boost creativity, improve emotional balance, and enhance focus
- Neuroplasticity: Psilocybin-containing mushrooms may modulate the Default Mode Network (DMN), contributing to decreased rumination and recursive negative thought patterns
- Therapeutic Introspection: Given their high potency, Copper Tops are noted for intense and emotionally revealing journeys that support therapeutic introspection
Important: While not officially recognized by pharmacological authorities, the mushrooms hold promise and are increasingly part of research proposals for broader clinical trials. Safe and supervised use is strongly advised due to their high potency and potential for disorienting psychological effects.
What Drugs Interact with Copper Tops?
Interactions with Prescription Medications:
- MAO Inhibitors (MAOIs): Can dramatically potentiate psilocybin effects, increasing the risk of serotonin syndrome—potentially fatal. Never combine with monoamine oxidase inhibitors such as phenelzine or Syrian rue
- SSRI Antidepressants: May dull or reduce psilocybin's effects and cause serotonergic imbalance. Medications like fluoxetine and sertraline can interfere with the experience
- Antipsychotics or Benzodiazepines: May counteract or abruptly suppress psilocybin effects, potentially destabilizing psychological integration
Other Substances:
- Stimulants: Amphetamines or cocaine increase the risk of elevated blood pressure, anxiety, or panic
- Alcohol: Increases risk of confusion, coordination loss, or traumatic psychedelic experiences
- Cannabis: May intensify effects unpredictably; use with extreme caution
Important: Copper Tops, containing psilocybin and psilocin, are susceptible to drug interactions that can impact mental state, brain chemistry, or pose potential health hazards. A cautious, one-substance-at-a-time approach is best.
