Paul Stamets’ Mycelium Running is a must have reference book for anyone working the land in any form, whether it be farming, forest management or environmental cleanup. But also for people who, like me, enjoy growing things, especially delectable edibles.

The book is filled to the brim with valuable information on how to improve soils for farming, gardening and forestry; create simple, low-cost biofilters for waste water (mycofiltration); and clean up toxic waste (mycoremediation).

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.

Another piece of useful information for farmers and gardeners found in Mycelium Running concerns the no-till farming method as opposed to the conventional method of plowing the fields after harvest. No-till farming helps promote saprophytic fungi (decomposing fungi), which break down organic material at a pace better suited to plant-life than the rapid and heat producing breakdown by anaerobic bacteria, which are the primary decomposers when stubble is plowed under. The mycelium of saprophytic fungi also binds the soil to prevent erosion and loss of valuable nutrients.

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.

The symbiotic mycorrhizal fungi can also be seeded in forests to promote healthy trees. Or they can be protected and naturally promoted through wise and informed forest management.

Mycorrhizal fungi help extend the reach of tree roots to better absorb nutrients and water, thus making the trees healthier and more drought resistant. Mycorrhizal fungi also manufacture and provide trees with natural antibiotics against many pathogens, especially parasitic fungi.

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.

Petrochemicals and biological warfare agents can be effectively broken down by mushroom mycelium, as can dioxin and toxic industrial waste. Even toxic levels of chlorine, which is used as the universal biocide, can be neutralized by some species of mushrooms. Bacterial contaminants like Staphylococcus sp. and E. coli can be killed, and heavy metals can be absorbed by mushrooms to then be removed from a site.

At $50 per ton, mycoremediation is a very cost effective method to clean up toxic waste. Conventional incineration may cost upwards of $1,500 per ton.

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.

Dr. Rafael has worked in natural health since finishing Chiropractic College in the mid-90’s. He currently focuses on medicinal fungi, frequently consulting two reference books: Mycelium Running by Paul Stamets for chemical, biological and medicinal properties of mushrooms, and Mushrooms Demystified by David Arora, the most complete identification guide of American mushrooms.
