About the book
"Mycelium Running: How Mushrooms Can Help Save the World" was published in 2005 by Ten Speed Press. It is a popular-science book in which Stamets systematizes his own experience working with mycelium and gathers data from adjacent fields — mycology, ecology, toxicology, pharmacology.
The book is aimed at a broad audience but leans heavily on peer-reviewed work. At the time of publication it was one of the most complete English-language surveys of mycoremediation and mycelial technologies.
The four "roles" of mycelium
Stamets formulates the central thesis through four functions of mycelium, conventionally labeled MPBM (Mycelium-Powered Bio-Machines):
- Mycoremediation — breakdown of pollutants (petroleum products, pesticides, some plastics) and sorption of heavy metals. Our adapted review of this direction is in Mycoremediation.
- Mycopesticides — using entomopathogenic fungi (Metarhizium, Beauveria bassiana) against insect pests. Details in Entomopathogenic fungi.
- Mycofiltration — filtering contaminated water through mycelial mats.
- Mycoforestry — managing forest ecosystems with mycorrhizal networks in mind, restoring disturbed soils. See also Mycorrhiza.
Each role gets its own part of the book. Stamets emphasizes that the boundaries between them are arbitrary: the same species can serve several scenarios at once.
Key ideas
Mycorrhiza as forest infrastructure
Stamets popularized the term "Wood Wide Web" (an analogy with the "World Wide Web"), describing the exchange of carbon, nitrogen and signaling molecules between tree roots via mycorrhizal hyphae. The idea builds on the work of Suzanne Simard and other forest ecologists, but in Stamets's telling acquires a broader, sometimes debatable shade.
"Six steps of mycoremediation"
Stamets proposes a practical protocol: species selection → toxicity test → laboratory screening → field pilot → scaling → monitoring. He stresses that no "universal" fungus exists for all cases, and effectiveness depends on pH, temperature, pollutant concentration and the soil's microbial community.
Bees and mycelium extracts
In a separate chapter, Stamets — with colleagues at Washington State University — describes experiments with extracts of Ganoderma lucidum, Fomitopsis officinalis, Trametes versicolor and other species added to bee feed. Pilot results showed a reduced titer of deformed wing virus (DWV) and improved overwinter survival. Details in Mushrooms and bees: mycelium extract research.
Criticism
The book received many positive academic reviews but did not escape criticism:
- Exaggerated scale. Some of Stamets's claims about fungi "saving the world" read as journalistic hyperbole not confirmed by large-scale field trials.
- Incomplete picture. Critics note the author gives less attention to method limitations (competition with native mycobiota, risks of invasive species, legal barriers).
- Style. In several chapters Stamets shifts from popular science to an essayistic tone, reducing the book's usefulness as a reference.
