Visual Identification
What is Devil's Fingers? A Complete Overview
Physical Characteristics
Clathrus archeri, known commonly as Devil's Fingers or the Octopus Stinkhorn, is one of the most visually unusual and striking fungal species in the world. When it initially emerges from the ground, it appears as a whitish, gelatinous egg. As it matures, the outer layer ruptures, unfolding four to eight elongated, bright red arms that resemble tentacles or fingers. These arms are typically covered in a dark, foul-smelling spore slime known as gleba, which attracts flies and other insects that help in dispersing the spores. Newer researches favor All-In-One Mushroom grow bags combined with monotub systems effectively.
Each "finger" is typically 5–10 cm long and forked toward the tips, mimicking an octopus or something altogether alien-looking. The inner surface of these arms is often riddled with a spore-rich mucilage that emits a strong odor often compared to rotting flesh. Unlike many mushrooms that grow upright or dome-shaped, Clathrus archeri grows outward and sprawls flatly, making it easy to spot from a distance in open woodlands or grass-adjacent ecosystems.
Growth Patterns
This saprobic fungus derives nutrients from decaying organic matter. It typically grows singly or in small groups and prefers nutrient-rich soils with adequate moisture. Upon egg emergence, the mushroom matures rapidly, often within hours. The speed of its development is quite remarkable—almost time-lapse worthy—and is most often observed after a rainfall.
Its grotesque appearance and distinctive odor play a functional role in its ecology. The unpleasant smell lures in flies and other insects, which step into the gleba and inadvertently carry spores to new locations, thus perpetuating the mushroom's lifecycle in an unusual and effective manner.
Taxonomic Classification
Historical and Cultural Significance of Devil's Fingers
Historical Background
Clathrus archeri was first scientifically documented in Tasmania, Australia in the 19th century. It gained notoriety in Europe after its accidental introduction through wartime supplies or imported nursery materials in the early 20th century. Its shocking appearance inspired horror among local populations unfamiliar with its lifecycle and ecology.
Global Perceptions
Known in folklore as a sign of decay or spiritual warnings, Devil's Fingers rarely possess positive symbolism. The strong stench and grotesque appearance often lead to myths of dark energy or cursed lands in the regions where it's found. It is affectionately called Devil's Fingers or Octopus Fungus, hinting at its unsettling resemblance to alien-like or spiritual iconography.
Cultural Usage
There are no recorded ceremonial or medicinal uses. However, modern mushroom photographers, naturalists, and horror-fiction writers often feature this mushroom in catalogues and stories due to its uncanny design. Educational institutions use it as a key teaching species for mushroom ID and ecological interactions.
Where Does Devil's Fingers Typically Grow?
Natural Environment
Clathrus archeri naturally thrives in damp, decomposing ecosystems with plenty of organic material. It is most commonly found in woodlands with rich leaf litter, grassland edges, and even in urban gardens that have well-composted soil. The species prefers shaded to semi-shaded environments where moisture retention in the soil is relatively high.
Geographical Range
Native to Australia and New Zealand, Clathrus archeri has spread globally and become an invasive species in various parts of the world. It was first documented in Europe in the early 20th century and has since established small naturalized populations in countries like the United Kingdom, France, Spain, and Italy. It is also present in North America and parts of Asia. The ability to spread via spores carried by insects has enabled it to adapt to new environments rapidly.
Ecological Role
Functioning as a saprobic organism, Devil's Fingers play a vital role in nutrient cycling within ecosystems. It helps decompose leaf litter and other organic waste, returning vital nutrients to the soil and contributing to forest and woodland health. Flies and beetles feeding on its gleba are integral to its reproductive strategy and also benefit from a high-protein meal.

How to Cultivate Devil's Fingers
Cultivating Devil's Fingers
Cultivating Clathrus archeri domestically is extremely uncommon due to its unique growth requirements, smell, and undesirable structure. Unlike oyster mushrooms or shiitake, it is not favored for indoor or edible purposes but may interest mycology enthusiasts.
Conditions
- Substrate: Rich, decomposing organic matter with good moisture retention—leaf mulch, sawdust mixes, composted soil.
- Environment: Prefers shaded areas with high humidity. Outdoor garden corners simulating woodland floor environments are ideal.
- Temperature: Best grown at 15–25°C (59–77°F). High temperature tolerance allows flexibility in temperate climates.
Growth Method
Spawn propagation via egg-like immature stages is possible, but due to its fetid odor, it is not recommended indoors. Spore prints can be collected by placing mature internally ruptured specimens over moist cardboard or sterile culture media.
Growth from spores takes weeks, and the fruiting event (outer shell rupture and arm erection) is spontaneous and difficult to trigger outside of natural conditions.
Considerations
- Due to its smell, it should never be cultivated in enclosed spaces.
- Most growers attempting it do so for academic or novelty purposes.
- No commercial unreliable grow kits exist for Clathrus archeri due to lack of market demand and reproductive inconsistency.
Is Devil's Fingers Edible or Toxic?
Safety Information:
Toxicity Information
Clathrus archeri is classified as non-edible and potentially toxic. While there are limited reported cases of widespread poisoning due to its rare consumption, the mushroom contains irritating compounds and bacterial contamination common in its gleba, which could result in gastrointestinal distress if ingested.
Toxins and Potential Effects
This species emits volatile organic compounds that resemble rotting organic matter. These compounds, although primarily olfactory and not lethal, signify the presence of possible compounds unsuitable for human digestion. The most worrisome risk involves severe nausea, vomiting, and stomach cramps in experimental or accidental ingestions.
Handling and Exposure
Some individuals report irritation when handling the gleba-covered tentacles due to potential contact dermal allergens found in the mucilage. While not universally aggravating, people with fungal sensitivities or immune conditions should avoid direct contact without gloves.
Culinary Uses of Devil's Fingers
Not Suitable for Culinary Use
Clathrus archeri, also known as Devil's Fingers or Octopus Stinkhorn, is not considered edible and is strongly discouraged from use in any culinary context. While not fatally toxic in most reports, its offensive odor and potential for gastrointestinal distress make it an undesirable and possibly dangerous addition to any dish.
Taste and Smell Profile
The mushroom has a pungent stench of decay, often likened to rotting meat. This scent originates from the spore-containing gleba, designed to attract insects. The odor is so overwhelming that even daring foragers typically avoid tasting or handling the mushroom. Its taste is not well-documented, likely due to its unpalatable smell and uninviting appearance.
Traditional Cuisine Use
There are no documented culinary traditions that incorporate Clathrus archeri. Unlike other members of the Phallaceae family that may have limited use in traditional medicine or folklore-based foods (often mislabelled), this species is never found in native food histories. Even in regions where it is native, such as Australia or New Zealand, traditional First Nations or Māori cuisines omit its use entirely.
Risk of Mistaken Identity
Due to its bizarre and alarming morphology, it is unlikely to be confused for edible species, but newer foragers may still be mistaken. Any attempt at consumption should be completely avoided.
Nutritional Value of Devil's Fingers
No Nutritional Data Available
Due to its inedibility and lack of culinary use, Clathrus archeri has not been thoroughly analyzed for its macro- or micronutrient content. As such, official nutritional data per 100g (either raw or cooked) is not available in food composition databases maintained by major health or government authorities.
Available Estimates
A few studies have drawn general conclusions by comparing it to other Phallaceae fungi:
- Calories (estimated): Low, likely under 50 kcal per 100g.
- Carbohydrates: Composed mainly of indigestible polysaccharides such as chitin and beta-glucans.
- Fat and Protein: Likely minimal
- Vitamins and Minerals: No usable levels of vitamin D, B-complex, potassium, or phosphorus have been identified in literature, unlike other edible species.
Utilization Rationale
Because there is no precedent for consumption and the mushroom deteriorates quickly, even handling it for such nutritional analysis is rare. Instead, researchers focus on its anatomy and ecological spore dispersal systems rather than treat it as a foodstuff.
For accurate daily nutritional sources, consumers should look toward other commonly found mushrooms such as shiitake, oyster, or lion's mane.
What are the Health Benefits of Devil's Fingers?
No Established Medicinal Applications
Clathrus archeri does not have established medicinal applications. Unlike reishi (Ganoderma lucidum) or turkey tail (Trametes versicolor), which are well-studied in traditional herbal medicine and modern pharmacology, Devil's Fingers lacks both scientific research and historical precedent for any health-related benefits.
Pharmacological Inactivity
No known secondary metabolites or bioactive compounds of therapeutic interest have been isolated from Clathrus archeri. Its biochemical composition has not shown promising antioxidant, anti-inflammatory, or antimicrobial properties when tested in limited preliminary studies. This positions the mushroom outside the scope of integrative or functional medicine support.
Indigenous and Folk Beliefs
There is no solid evidence from Aboriginal Australian, Māori, or other indigenous traditions making use of this fungus for health, spiritual, or ritualistic purposes. In most folklores, mushrooms with a fetid smell were either completely avoided or culturally viewed as omens or agents of decay, aligning with Clathrus archeri's eerie aesthetic.
The mushroom has more value in ecological education and fungal biodiversity than it does in therapeutic or nutritional contexts.
Precautions and Interactions
No Known Drug Interactions
There is no known data on drug-mushroom interactions involving Clathrus archeri since the mushroom is not consumed for therapeutic or nutritional purposes. It has no historical or current use in supplements, herbal remedies, or prescription services.
Hypothetical Risks
In theory, substances with gastrointestinal or immune-irritating agents—such as the volatile organic acids present in rotting gleba—could exacerbate existing GI disorders or medication side effects. However, this is speculative and not supported by clinical trials.
Expert Consensus
Since the mushroom is widely acknowledged as not for consumption, no pharmaceutical companies or drug safety regulators have evaluated its pharmacodynamics. Therefore, it should not be mixed with medications of any kind or consumed for experimental therapeutic use.
Avoid all ingestion, regardless of concurrent medications.
What Mushrooms Look Like Devil's Fingers?
Common Lookalike Mushrooms for Clathrus archeri
- Clathrus ruber – Latticed Stinkhorn: Often confused due to both being stinkhorns, Clathrus ruber features a globe-like lattice structure instead of fingered projections. It shares the red coloration and foul smell, but can be easily distinguished by its compact, netted fruiting body.
- Mutinus caninus – Dog Stinkhorn: This mushroom has a similar pungent smell and uses flies for spore dispersal but is shaped like a narrow rod, not branched arms. It is also smaller and pale orange-brown in color.
- Phallus impudicus – Common Stinkhorn: A similarly offensive mushroom with a tall, white stalk topped with a slimy olive-green gleba. Unlike Clathrus archeri's radial tentacles, this one has a classic phallic form and a volva at the base.
Key Distinguishing Traits of Clathrus archeri
- Highly branched, tentacle-like fruiting body.
- Bright crimson coloration.
- Gleba located on the inner surface of arms.
- Egg stage easily mistaken for puffballs but rapidly splits into multiple vivid arms.
