Paul Stamets' Mycelium Running

By Dr. Markho Rafael

The best-selling book on "popular mycology," Mycelium Running, would be a useful reference book in every home, especially to anyone involved in farming (or gardening), forest management and environmental cleanup. The second half of the book is an instruction manual on growing delectable mushrooms for food and medicine.

The book is a treasure trove of useful practical information on what Stamets refers to as mycofiltration (of water), mycoremediation (of toxic waste), and tips on how mushroom mycelium can help improve soils and boost productivity in farming and forestry with less use of pesticides and fertilizers.

For example, an easy do-it-yourself method of creating a mycofiltration bed for filtering waste water is delineated in detail. Recommended materials are listed along with suggested mushroom species to use and the ideal dimensions of the bed. In Stamets' examples, these mycofiltration beds are used to effectively filter and neutralize farm runoff but they could also be used to filter industrial waste water.

Not only does it solve the problem of farm runoff and E. coli contamination of nearby streams, it can also yield highly palatable food mushrooms, and the bed itself can be dug out every 2-3 years and then used as an excellent fertilizer for the farm.

Benefits of no-till farming are described in terms of how it supports saprophytic soil fungi, which in turn help protect the soil from erosion as well as break down organic matter at a rate that is better paced to benefit plant life than if the stubble were to be plowed under and broken down by anaerobic bacteria.

Saprophytic fungi benefit forests too, by breaking down organic matter but also help by competing with parasitic fungi (blights), which may kill thousands of trees if not stopped. Foresters can easily seed saprophytic mushrooms in blight infested areas as a natural fungicide against parasitic fungi, fighting fire with fire.

Mycorrhizal fungi likewise can be seeded to support tree growth, or these beneficial fungi may simply be encouraged to grow naturally through smarter and more enlightened forest management.

Most plants form symbiotic relationships with mushrooms. The mushroom mycelium more effectively absorbs water and nutrients, exchanged with trees for sugars, making the trees healthier and more drought resistant. Mycorrhizal fungi also provide trees with natural antibiotics against pathogens.

Another cutting edge technology in Mycelium Running is Mycoremediation, the neutralization of toxins through the use of mushroom mycelium. The term Mycoremediation was coined by Paul Stamets, author of Mycelium Running, but was already in common use among mycologists before publication.

Synthetic toxic compounds including petrochemicals, dioxins, neurotoxins, toxic industrial waste and much more can be effectively broken down by fungi into harmless compounds. Bacterial contaminants such E. coli can be killed by anti-bacterial compounds excreted by the fungi. And toxic levels of heavy metals may be absorbed and concentrated by mushrooms, which can then be harvested and safely deposed.

Mycoremediation is extremely economical, at less than 5% the cost of some conventional methods for cleaning up toxic waste.

This plethora of information is merely the first half of this 300-page tome. Part III, which makes up the second half of the book, is an instruction manual on how to cultivate your own mushroom mycelium, which can be used for the above listed purposes, or to grow your own medicinal or culinary mushrooms. And seriously, who doesn't love gourmet mushrooms? In other words, this is a reference book for every household.
