What it's about

Merlin Sheldrake argues that fungi are not passive decomposers at the margins of life but active, intelligent-seeming organizers of nearly every terrestrial ecosystem. Through mycorrhizal networks, lichen partnerships, fermentation, and psychoactive mushrooms, he shows fungi dissolve boundaries we assume are fixed: between individual and colony, plant and soil, mind and matter. The book matters because it forces a rethink of biological individuality and cognition using organisms most readers have never considered as agents at all.

Pick a finish date and Genius lays out the days — the plan shows today's target and keeps you honest.

Read together

Start a circle and share the code — everyone sees everyone's honest place in the book. Accountability, not leaderboards.

Who it's for

- Gardeners and foragers curious about the biology beneath the soil they work - Readers of popular science who enjoyed rethinking plant or animal cognition and want the same treatment for fungi - Anyone interested in psychedelics, fermentation, or ecology who wants the underlying science explained without jargon

What’s inside

1
What a Fungus Is Not
Fungi cannot be understood by analogy to plants or animals because they possess a fundamentally different body plan and way of encountering the world.
1 min
2
The Ancient Bargain That Made Land Livable
Terrestrial life as we know it exists only because fungi and plants struck a nutrient-exchange partnership roughly 450 million years ago, and most plants still depend on it.
1 min
3
Underground Networks and the 'Wood Wide Web' Question
Mycorrhizal fungi can link multiple trees into shared underground networks, but the popular claim that trees use these networks to deliberately communicate or cooperate outstrips the current evidence.
1 min
4
Lichens: Individuals That Are Actually Committees
A lichen is not a single organism but a stable partnership of fungus and photosynthetic algae or bacteria, and this composite nature undermines the everyday concept of a biological individual.
1 min
5
Fermentation and the Domestication of Fungal Metabolism
Human civilization's food and drink traditions are not just flavored by fungi but structurally dependent on redirecting fungal metabolic byproducts toward human ends.
1 min
6
Mycelial Networks as a Model of Distributed Problem-Solving
Fungal mycelium can solve navigational and resource-allocation problems without a brain, suggesting cognition need not require neurons, though calling this 'intelligence' remains a contested framing.
1 min
7
Psilocybin and the Reopening of Psychedelic Research
Psilocybin mushrooms' effects on human consciousness reveal something about both fungal chemistry and the plasticity of human perception, and the scientific stigma around studying them was a policy failure, not a evidentiary one.
1 min
8
Radical Mycology and the Question of Fungal Futures
Fungi's unusual metabolic capabilities make them promising tools for solving human problems like plastic waste and soil contamination, but the practical scale-up of these applications remains largely unproven outside small trials.

About Merlin Sheldrake

Merlin Sheldrake holds a PhD in tropical ecology from Cambridge, where he studied underground fungal networks in Panama's forests. He works as a scientist and writer specializing in mycorrhizal symbiosis, plant-fungal ecology, and biochemistry, and has practiced fermentation and mycology as hands-on crafts alongside his academic research.
