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.

Mycelium Running is filled to the brim with useful tips on things such as using mushrooms to improve soils and boost productivity in forestry and farming (gardening) with decreased use of expensive fertilizers and pesticides; filtering waste-water (mycofiltration); and clean up toxic waste from the land (mycoremediation).

A detailed description of Mycofiltration, the use of mushrooms to filter waste water, is given in one section of the book. It lists recommended mushroom species and materials to use in creating the mycofiltration bed, as well as dimensions, depth, layers, etc. Mycofiltration beds like this can be effectively used for both industrial waste water and farm runoff.

An added benefit of using mycofiltration beds on farms include the production of delicious food mushrooms, which sprout out of these beds. And every 2-3 years, the material in the bed can be dug out and used as a rich fertilizer on the fields of the farm.

Also useful for farmers is the information on no-till farming, which involves a method of leaving the stubble on the field until the next crops is planted. This encourages the development of saprophytic fungi, which break down old plant matter at a pace that's highly beneficial for new plant life. In contrast, the conventional method of plowing down the stubble after harvest promotes anaerobic bacteria, which decompose organic substrate too rapidly. The saprophytic fungi also help prevent soil erosion and leaching of valuable nutrients and top soil.

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 mushrooms can also be seeded to support the forest, or they may simply be encouraged to grow naturally by using more enlightened methods of 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.

Mushroom mycelium can also be utilized to clean up toxic waste sites through a method known as mycoremediation. The term was invented by the author of Mycelium Running, Paul Stamets, but was in common use before the publication of this book.

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 has also been shown to be the most economical method of cleaning up toxic waste sites, up to 95% cheaper than some common conventional methods.

All that is just in the first half of this 300-page book; the second half is an instruction manual on growing your own mushrooms and mycelia, which is something that may be of interest to forest managers for mycoforestry, environmentalists for mycoremediation, farmers for increasing soil productivity, and the rest of us for growing our own gourmet mushrooms for food and medicine. In other words, this is a book for anyone and everyone. - 30228
