What is Panaeolus cambodginiensis? A Complete Overview
Morphological Overview
Panaeolus cambodginiensis is a potent psychoactive mushroom known for its distinctive appearance and high psilocybin content. This species features a small to medium-sized fruiting body, with caps typically ranging from 1.5 to 4 cm in diameter. The cap is commonly bell-shaped when young, becoming more convex or plane with age. Coloration tends to range from a light gray or pale golden to a more tan hue, darkening when moist due to its hygrophanous nature. Growers achieve success with All-In-One Mushroom grow bags and shoebox containers quite easily.
Key Identification Traits
One of its defining features is the black spore print and the mottled gills—a characteristic trait of Panaeolus species. The stem is slender and white, often bruising blue when handled, a key indicator of its psychoactive properties. Compared to other Panaeolus species like Panaeolus cyanescens, cambodginiensis often has a denser fruit body and more vivid blue bruising.
Geographic Origin and Distribution
As the name suggests, this mushroom was originally identified in Cambodia, specifically from substrate material associated with grazing animals. However, it is now known to exist in other Southeast Asian countries and tropical climates globally.
Psychoactive Properties
Panaeolus cambodginiensis contains high levels of psilocybin and psilocin, making it one of the more potent naturally occurring psychedelic mushrooms. This species is often favored for its strong visual hallucinations and euphoria, although dosage should be approached with caution due to its high potency.

Panaeolus cambodginiensis was first described in scientific literature in the early 1970s by famed ethnomycologist Gastón Guzmán, in collaboration with other researchers studying psychoactive fungi in the Mekong River region. Its name pays tribute to its origin—Cambodia—where it was reportedly discovered growing on water buffalo dung in a tropical pasture near the famed Angkor Wat temple complex.
Traditional and Indigenous Use
While there isn't substantial documentation of long-standing indigenous ceremonial use specific to Panaeolus cambodginiensis in Cambodian culture, psychoactive mushrooms in general have played significant roles in Southeast Asian shamanic practices. Shamans in neighboring regions—such as Thailand and Laos—have been known to incorporate similar psilocybin-containing mushrooms into religious or divinatory rituals.
Global Relevance in Psychedelic Culture
In the modern era of psychedelics, Panaeolus cambodginiensis has become particularly popular among psychonauts and home cultivators due to its high potency and ease of fruiting under tropical conditions. It has been featured in many cultivation guides and is often referred to in online forums as a reliable species for intense experiences. The strain's discovery added significantly to the diversity of known psychoactive mushrooms during the Western psychedelic revival in the second half of the 20th century.
Influence on Mycology and Psychedelic Research
While not as widely studied in laboratory settings as Psilocybe cubensis or Psilocybe semilanceata, the unique alkaloid profile and resilience of Panaeolus cambodginiensis continue to draw attention from amateur and professional mycologists alike. It remains a key example of non-Psilocybe psychoactive fungi that have transcended their native habitat to become staples in global psychedelic education and exploration.
How to Cultivate Panaeolus cambodginiensis
Difficulty Level: Advanced - requires specific substrate requirements and careful environmental control.
Substrate Requirements:
Panaeolus cambodginiensis thrives on nutrient-rich substrates, particularly those derived from decomposing manure, making it a classic coprophilous species. That said, for cleaner and more modern cultivation, our sterilized milo grain bags offer an ideal inoculation medium compared to traditional methods. These grain bags are nutrient-dense, highly colonizable, and reduce contamination risks.
Once colonized, the mushroom performs excellently on our CVG (Coco Coir, Vermiculite, Gypsum) substrate, which provides a cleaner alternative to raw manure. CVG not only eliminates unpleasant odors but also maintains superior water retention and structural integrity during fruiting.
Ideal Environmental Conditions:
- Colonization Temperature: 78°F to 82°F (25°C–28°C)
- Fruiting Temperature: 70°F to 75°F (21°C–24°C)
- Humidity: 90%+ during colonization and fruiting
- Air Exchange: Fresh air exchange crucial during fruiting
- Lighting: Indirect lighting (12 hours per day)
Colonization and Fruiting:
Colonization time typically ranges from 10 to 15 days depending on strain vigor and environmental control. Once fully colonized, fruiting generally occurs within 7–10 days after exposure to fruiting conditions. Mature specimens can be harvested within three to five days of pinning.
All-In-One Grow Kits:
For beginner cultivators or for streamlined production, our all-in-one grow kits offer the simplest route. These pre-sterilized bags come filled with both grain and CVG, eliminating the need for transfers or exposure to contamination. Simply inject with a spore syringe or liquid culture, allow colonization, and fruit directly in-bag or in a monotub setup.
These kits are especially convenient for species like Panaeolus cambodginiensis due to their aggressive mycelial growth and sensitivity to contamination. With our all-in-one kits, even novice growers can yield professional results.
Where Does Panaeolus cambodginiensis Typically Grow?
Environmental Preferences
Panaeolus cambodginiensis is a tropical species that prefers warm, moist climates with steady humidity. Its optimal habitat includes pastures, grasslands, and open forest edges, particularly where livestock has been present. This mushroom is coprophilous, meaning it grows directly on or near herbivore dung.
Geographic Distribution
Originally discovered in Cambodia, it has since been documented in regions across Southeast Asia, such as Thailand, Vietnam, Laos, and southern China. Reports also indicate its natural occurrence in Central and South America, Australia, and Florida, predominantly in well-fertilized pasturelands.
Soil and Substrate Conditions
The mushroom prefers rich organic matter, especially nitrogen-rich substrates like water buffalo or cow dung. This species is rarely found on leaf litter or in decaying wood, distinguishing it from many woodland-dwelling species. High ambient humidity and rainy seasons favor its growth, often after successive days of steady rainfall.
Altitude and Ecosystem Type
Though more common in lowland tropical zones, Panaeolus cambodginiensis can also be found at moderate altitudes up to 1000 meters where conditions remain warm and moist. Open-field ecosystems that receive direct sunlight promote faster fruiting than deep shaded forests.
Overall, its wild proliferation depends on a delicate balance of warmth, moisture, animal activity, and shade.
When is Panaeolus cambodginiensis in Season?
Typically found from May to October during warm, rainy seasons in tropical and subtropical regions.
Is Panaeolus cambodginiensis Edible or Toxic?
Toxicity Information:
General Safety
Panaeolus cambodginiensis, while psychoactive, is not considered toxic in small to moderate dosages. The primary active components—psilocybin and psilocin—are physiologically safe for most individuals under supervised, intentional use.
Adverse Effects
However, improper dosage or predisposition to mental health disorders can exacerbate psychological side effects such as panic, anxiety, or psychotic episodes. Nausea, dizziness, sweating, and coordination loss are common during the onset stages.
Overdose and Risk Profile
While the potential for physical toxicity is low, psychological overdosing can occur. Extremely high doses (exceeding 5g dried) can cause intense mental disorientation. Users may experience terrifying hallucinations, ego dissolution, or paranoia. Set and setting strongly influence outcomes.
Toxic Lookalikes
One of the greater risks with Panaeolus cambodginiensis is misidentification in the wild. Non-psychoactive or poisonous lookalikes within the Panaeolus or similar genera like Conocybe, or Parasola, can make for dangerous mistakes if foraged based on superficial traits. As such, clinical cultivation or experienced identification is essential.
What are the Medicinal Uses for Panaeolus cambodginiensis?
Cognitive and Emotional Benefits
Though primarily used for its psychoactive effects, Panaeolus cambodginiensis contains psilocybin and psilocin, which are increasingly being researched for their potential in treating mental health disorders. Emerging studies suggest that structured psilocybin experiences can lead to reductions in depression, anxiety, and PTSD symptoms. Users have reported improved creative thinking, emotional awareness, and long-term positive shifts in mood after responsible use.
Neurological Regeneration
Preliminary scientific research indicates that psilocybin may promote neurogenesis and increased neural plasticity, laying the groundwork for potential treatments for neurodegenerative diseases like Alzheimer's and Parkinson's. Panaeolus cambodginiensis, due to its high psilocybin concentration, could offer a similar therapeutic profile when studied under clinical conditions.
Anti-inflammatory and Antioxidant Potential
There is some evidence to support the broader family of Psilocybin fungi—especially mushroom compounds like ergothioneine—as possessing mild antioxidant and anti-inflammatory effects. While specific studies focused on P. cambodginiensis are limited, it likely shares many of these systemic health benefits.
Microdosing Applications
Although typically consumed in higher doses for profound experiences, microdosing Panaeolus cambodginiensis in safely measured quantities (0.05–0.25g dried) has been reported by some users to enhance focus, productivity, and emotional regulation without reaching intoxication. These anecdotal benefits align with what has been observed in more heavily researched species.
Important: Medical applications are still under study, and current regulatory frameworks vary globally. Always consult healthcare professionals before considering therapeutic use.
What Drugs Interact with Panaeolus cambodginiensis?
Pharmaceuticals
Psilocybin mushrooms like Panaeolus cambodginiensis should not be mixed with SSRIs, MAOIs, or antipsychotic drugs. SSRI antidepressants may dull the psychoactive effects without reducing emotional volatility, while MAOIs (like those found in ayahuasca) can dangerously potentiate psilocin via metabolic interference. Combining mushrooms with lithium, benzodiazepines, or amphetamines may also exacerbate negative symptoms or compromise emotional regulation.
Recreational Substances
Combining this species with alcohol, cannabis, or other psychedelics (e.g. LSD or DMT) can intensify the experience but also increases unpredictability in effects. Adrenaline spikes, blood pressure shifts, and irrational behaviors become more probable.
Herbal Interactions
Interactions with common nootropics or adaptogenic herbs like Rhodiola, Passionflower, or Ashwagandha are not well-documented. However, users have occasionally reported synergistic sedative or calming effects when pairing mushroom use with nervines.
Dietary Considerations
Taking psilocybin mushrooms on a full stomach may slow onset and dull effects. Conversely, fasting or combining with citrus (lemon tekking, for instance) can intensify and accelerate absorption due to pH-based enzymatic activity.
Safety Summary
Due to the intense nature of P. cambodginiensis, it is strongly advised to consume in isolation or after thorough research into any pharmacokinetic interactions that may elevate risk.
What Mushrooms Look Like Panaeolus cambodginiensis?
Panaeolus cambodginiensis may be confused in the wild with several look-alike mushroom species:
- Panaeolus cyanescens: One of the most commonly confused species is Panaeolus cyanescens, another potent psychedelic in the same genus. They share similar environments, black spore prints, and hygrophanous caps. However, cambodginiensis is usually slightly darker, has more robust bruising, and features a denser, more compact cap.
- Panaeolus antillarum: Though not psychoactive, Panaeolus antillarum appears similar during early growth. It is often brighter white and lacks any blue bruising. Mistaking this for cambodginiensis would result in a lack of desired psychedelic effects, not toxicity.
- Conocybe spp.: Several Conocybe species, such as Conocybe filaris, can resemble small Panaeolus mushrooms. Unlike cambodginiensis, these carry dangerous toxins like amatoxins, which can cause fatal liver failure. Always differentiate by checking for bruising and spore color.
- Parasola spp.: Species in the Parasola genus, including Parasola plicatilis, are common grassland mushrooms that may appear similar from afar. These have thin, fragile caps and white gills, easily separating them from the darker, sturdy cambodginiensis upon closer inspection.
- Psathyrella spp.: Some Psathyrella species also have dark spores and grow in wet pastures. They lack psilocybin, and their caps and gills remain more fragile, not exhibiting any psychoactive traits or blue bruising.
Safety Note: Safe identification should involve checking for blue bruising, black spore prints, and understanding habitat context. Spore microscopy or DNA testing provides definitive confirmation where available. Misidentification can have severe consequences, so caution, documentation, and expert consultation are critical in any wild foraging context.
