Mycelium Running by Paul Stamets has been the perpetual best-seller on popular mycology since published in 2005. It’s an indispensible reference book for anybody working the land, especially foresters, farmers and environmental cleanup contractors. It’s also a great book for anyone interested in growing their own food mushrooms.

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.

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.

Added perks when using mycofiltration is that the beds also yield crops of scrumptious food mushrooms, and every 2-3 years, as the bedding material needs to be replaced, the old material can be spread on the farm fields as a rich fertilizer.

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.

In addition to helping decompose and recycle organic matter, saprophytic fungi can also help forestry by protecting its tree residents from parasitic fungi (blights), which may kill thousands of trees if left unchecked. Seeding saprophytic fungi in a productive forest may help out-compete parasitic fungi, thus functioning as natural fungicides; good fungi vs. bad fungi.

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.

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.

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.

The information listed above is still only the first half of this tome. The second half is filled with information on growing mushroom mycelium, which can then be used for the above-mentioned purposes, or for growing our own medicinal or edible mushrooms. And who doesn’t love gourmet mushrooms? In other words, this is not only a book for farmers, foresters, ecologists and mycologists. This is a valuable reference book for every home and household.
