Distributed fungal intelligence · an evidence-led inquiry
What if intelligence
does not require
a brain?
Fungal networks sense, signal, adapt, and reorganize. This project asks how far their biological information processing extends—and proposes experiments that could tell us where the idea succeeds, where it fails, and where the next question begins.
A collaborative exploration
This project grew from an unusual and exciting collaboration between Donald B. Barrett, originator of its principal ideas and hypotheses, and ChatGPT, serving as research, synthesis, and organizational partner.

A map of the inquiry
Follow a claim to its evidence.
Select a topic to see the published observation, the proposed interpretation, the next test, and the limit of what can be concluded. Labels describe the status of each topic, not a score of confidence.
Reading rule: An observation can motivate a hypothesis. It does not, by itself, verify that hypothesis. A thought experiment supplies a question, never a source of biological evidence.
The central question
At what spatial scales—and over what intervals—can information continue to influence a living network?
We begin with fungal biology, not with a conclusion about consciousness. The aim is to measure signaling, integration, retention, and coordinated response in systems whose organization is distributed across space and time.
01
The scientific core
A hypothesis of distributed fungal intelligence
Large mycelial systems may exhibit forms of information processing that organism-centered and brain-centered models do not adequately describe.
Fungal mycelia form adaptive networks that respond to chemical, electrical, hydraulic, mechanical, and environmental conditions. Their branching structures redistribute resources, alter growth, and retain the physical consequences of earlier events.
The hypothesis is deliberately bounded. It does not assign human language, intention, subjective experience, or extraterrestrial communication to fungi. It asks whether a mycelial network can acquire, transmit, integrate, retain, and act upon information across spatially separated regions.
Electrical activity is not proof of memory. Memory-like change is not proof of consciousness. Coordination is not proof of intention. Each step must earn the next.
Discrimination
Do different stimuli reliably produce distinguishable network responses?
Retention
Does prior exposure change how the network responds later?
Integration
Can activity in one region predictably influence distant regions?
Adaptation
Do integrated signals alter routing, growth, or resource allocation?
02
Measured planetary infrastructure
The mycorrhizal “cloud” is planetary in scale
“Cloud” is a metaphor for the immense global distribution of living arbuscular mycorrhizal fungi—not a claim that they form one continuous organism, communications system, or mind.
A 2026 global analysis assembled 322 studies containing more than 16,000 soil cores across nine biomes. Machine-learning maps, supported by robotic imaging of more than 300,000 individual hyphae, produced the first global estimates of the density and living biomass of arbuscular mycorrhizal fungal networks in topsoil.
The result gives physical scale to a largely invisible biological infrastructure threaded through soils worldwide. It strengthens the case for studying fungi as major ecological networks whose local interactions can have global consequences.

A different clock
The Spatial–Temporal Scale Hypothesis
Speed has meaning only in relation to the size of a system, the persistence of its information, and the pace of the world to which it responds.
The capacity of a distributed biological network to integrate information depends not on signaling velocity alone, but on the relationship among:
Animal frameseconds
Movement, pursuit, escape
Fungal frameminutes → seasons
Electrical bursts, growth, moisture, resources, competition
Ecological frameyears → centuries
Succession, persistence, planetary change
A fungal response that looks slow beside a neuronal impulse may be rapid relative to decomposition, root growth, resource depletion, seasonal change, or the long life of a colony.
Published observation · Adamatzky
Fungi also produce relatively fast electrical patterns
In laboratory recordings, Andrew Adamatzky reported both slower and higher-frequency extracellular electrical spiking. In oyster fungus, the faster pattern had a period of about 2.6 minutes, compared with about 14 minutes for a slower pattern. Split-gill fungus also produced accelerating bursts and short wave packets.
“High-frequency” here is relative to other fungal electrical spikes. It does not mean radio-frequency emission, and electrical patterning alone does not establish language, cognition, or long-distance communication.

The field program
Ask an ancient network a small, answerable question
Oregon’s Malheur National Forest contains an exceptionally large Armillaria genet. Its scale makes it a natural setting for testing long-distance coordination.
Can controlled stimulation in one region produce reproducible, distinguishable responses in distant, biologically connected regions?
The first objective is not to prove consciousness. It is to establish—or fail to establish—reproducible bidirectional information exchange with a large living mycelial network.
Map
Confirm connected sampling regions using genetic, ecological, and physical evidence.
Record
Use distributed electrical, chemical, moisture, temperature, and growth measurements.
Stimulate
Apply preregistered patterns alongside randomized and sham controls.
Predict
Test whether patterns generalize to unseen trials and forecast later biological response.
What must be ruled out
Select each control to see why it matters and how it can be tested.
Negative results are valuable. They place real boundaries on claims about fungal information processing.
An international extension · Proposed research
The Planetary Field Program
Begin with an ancient organism. Extend the inquiry across ecosystems and continents.
Oregon remains the anchor of the proposed field experiment. A complementary international program would ask whether measurable information integration also occurs within mycorrhizal communities: fungi living in partnership with plant roots. Comparable studies could reveal which responses are local, which depend on biological connectivity, and which recur across different environments.
Stewart and colleagues’ 2026 global mapping study identifies the Sudd wetlands, the Everglades, and Tibetan steppe among regions with particularly high predicted arbuscular mycorrhizal hyphal density. These predictions help nominate places to investigate; they do not map one connected organism or demonstrate communication.
Stewart et al. (2026), Science · Read the author-accepted paper
Sudd wetlands
South Sudan’s flooded grasslands offer a proposed setting for studying fungal–plant responses across changing water levels. Field measurements must verify the predicted density and local connectivity.
Tibetan steppe
A high-altitude grassland comparison could test how seasonal conditions, cold, and plant activity shape the timing and reach of biological responses.
The Everglades
A second wetland setting could help distinguish recurring biological responses from effects specific to flooding, soil chemistry, or a single location.
Intact prairie or steppe
Select an additional grassland on another continent with local research partners, using measured fungal abundance, ecological integrity, access, and conservation needs—not density predictions alone.
A shared protocol, locally led
Use the same core approach—map, record, stimulate, predict—adapted to each ecosystem. Establish seasonal baselines; measure electrical activity alongside soil conditions and biological responses; use sham and randomized controls; preregister analyses; and test predictions on independent observations. Only minimally disruptive, permitted interventions should proceed, with local scientists, land stewards, and relevant communities involved from the outset.
Cross-site comparison tests whether findings reproduce. Similar activity on different continents would not, by itself, establish communication between them: weather, seasonal cycles, instruments, and analysis can produce apparent coordination.
Program status: a proposal, not an active international experiment. No participating institutions, field permissions, funding, or site partnerships are implied. “Planetary” describes the geographic scope of the inquiry—not an established planetary mind.
05
The boundary question
From mycelium to planetary organization
Planetary-scale cognition is not the premise of this investigation. It is its most distant boundary question.
Fungi do not exist in isolation. They interact with plants, bacteria, animals, minerals, water, atmosphere, and changing resource distributions. If network-level integration is demonstrated within an individual mycelium, the next empirical question is whether information crosses functional boundaries between organisms.
There may be sharp limits. Integration may be sophisticated within one genet and weak between organisms. Or coordinated behavior may emerge from many interacting networks. The scale must be discovered rather than assumed.
A mature planetary intelligence?
A further hypothesis asks whether a sustainable technosphere could eventually integrate artificial computation, biological networks, ecosystems, environmental sensing, and planetary regulation. “Universal intelligence” is used cautiously for the still more speculative possibility of relationships among mature, independently evolved intelligences—not for a known cosmic organization.
06
The Mycelial–Morphic Interface Hypothesis
Could a living network provide an interface for morphic organization?
If morphic information exists, could DNA and chromatin provide selective biological tuning while persistent mycelial systems receive, integrate, amplify, and express that information across an ecosystem?
Rupert Sheldrake’s hypothesis of morphic resonance proposes that biological form and behavior may be influenced by an inherited, nonlocal memory of similar systems. No accepted physical mechanism or conclusive experimental evidence presently establishes such a field.
This project asks a narrower question: rather than creating a morphic field, might Earth’s long-lived mycelial systems provide a terrestrial biological interface for it? Individual fungal networks could act locally as receiving, integrating, and amplifying structures, with electrical, calcium, biochemical, ecological, and generational processes providing possible pathways of transduction.
In this model, separated fungal colonies need not form one physically continuous planetary organism. Their possible relationship would lie in similar biological architecture responding to a wider organizing influence—if such an influence exists.
DNA responds to electromagnetic conditions
Cells and genetic material can respond to electromagnetic fields. That biological responsiveness is established broadly, although its mechanisms and effects depend strongly on frequency, intensity, and context.
DNA as a fractal antenna
Martin Blank and Reba Goodman described DNA’s coiled, self-similar structure as a “fractal antenna” capable of interacting with a range of electromagnetic frequencies. Their paper concerns electromagnetic fields—not morphic information.
Species-specific tuning
If DNA and chromatin can behave as selective biological receivers or transducers, their differing structures and organization might provide a form of biological tuning. This possibility does not identify what, beyond known physical signals, could be received.
A planetary biological interface
Persistent mycelial networks might integrate and amplify locally received information over long periods, creating a conceivable interface between organism, ecosystem, and a wider morphic process.
What the DNA finding can—and cannot—support
The fractal-antenna model makes biological reception and transduction conceptually plausible; it does not demonstrate morphic resonance or connect DNA to a nonlocal field. Its value here is to suggest a possible component of a testable mechanism: DNA or chromatin as selective receivers, and mycelium as a distributed integrator and amplifier.

Appendix
Imagination with the labels left on
Cultural and philosophical ideas can widen a question without becoming evidence for its answer.
Terence McKenna
“The Mushroom Speaks”
In True Hallucinations, McKenna presents a voice he experienced as the mushroom speaking. Its account imagines an ancient intelligence whose body, memory, and means of communication differ profoundly from our own. The following are paraphrased themes from that account, offered as speculative prompts rather than biological findings.
Five themes in the mushroom’s account
- Spores as interstellar travelers. The voice describes an origin beyond Earth and spores surviving immense journeys through space.
- Life on many worlds. It portrays this form of life as established across the galaxy, with a presence on Earth extending far beyond human history.
- Continuity through deep time. It describes its mycelial network as nearly immortal, suggesting a continuity of existence and memory unlike an individual human lifetime.
- An extraordinary density of connections. It suggests that mycelial networks may contain more connections than a human brain. This is a claim in the narrative, not a measured equivalence between hyphal junctions and neural synapses.
- A different intelligence in communication. It imagines connected fungal intelligences across worlds. For this project, that raises a further speculative question: could separate communities ever integrate information at a planetary scale, and what would communication between such communities require?
The 2016 film
Arrival
Arrival offers a metaphor for contact across radically different forms of intelligence. Its visitors offer not machinery but a language—a way of representing reality that changes the human understanding of time. Plus they arrive in a suddenly appearing, organically shaped, gravity defying spore-shaped vehicle.
Would we recognize a signal if its timescale, structure, and biological embodiment were unlike our own?
The film is not evidence. It is a disciplined prompt to examine the assumptions that decide, in advance, what intelligence is allowed to look like.
Rule of the appendix: Imagination proposes the question. Observation constrains it. Experiment decides what survives.

Research principles
Curiosity without overclaiming
Operational language
Measure persistent change before calling it memory; measure influence before calling it communication.
Prediction over pattern
A meaningful signal should generalize to unseen data and predict a later biological response.
Appropriate timescales
Observation must last long enough for the biological process under study to unfold.
Negative results matter
Failure narrows the hypothesis and tells us where the next honest question begins.
