Contrary to what many cultivation cognoscenti repeatedly say, this book is not the `bible' of mushroom cultivation. Although the amount of information in this book is impressive, it is limited to a handful of species, and gives exact growth parameters for a few select mushrooms, principally those belonging to Agaricus, Pleurotus, Psilocybe/Panaeolus, and Stropharia. It should also be noted that while some species, such as Pleurotus and Agaricus are relatively easy to cultivate, others such as Stropharia and Psilocybe/Panaeolus may be difficult to cultivate even under the most favorable conditions. As many of the topics in the book are more appropriate for the small mushroom farm, the book is anything but practical for home-based cultivation. As a result, using this book as a basis for hobby cultivation will more than likely take the fun out of cultivation entirely.
That said, the book explains the science behind mushroom cultivation very well, but places considerable emphasis on composting and Agaricus/Psilocybe production. The emphasis on Agaricus is understandable, as it is a commercially cultivated mushroom with mass appeal, but Psilocybe species are covered in a bit too much detail for my taste. More lab techniques are presented in this book than in Stamet's Growing Gourmet Mushrooms, and the authors provide detailed info on starting cultures from scratch, spawn maintenance and propagation, as well as setting up your own lab. One very strong selling point of the book is the authors' elaboration on the importance of good environmental control and how to achieve it, although again, the information on this topic would be more appropriate for a farm than a home. The authors also include two very detailed chapters giving information on invertebrate (insect) and microbial pests/contaminants and provide an excellent chapter on trouble-shooting during cultivation, focusing in particular on microbial pests/contaminants. The book includes a fairly good run-down on cultivation using non-composted substrates, but it could be expanded to include more substrates, more cultivation strategies, and more mushroom species that grow well on non-composted substrates. However, Stamets and Chilton primarily refer to varieties of alder, which is readily available in riparian and montaine habitats in the Pacific Northwest, and while they do provide the reader with material properties on other suitable hardwood substrates such as oak, beech, and birch in an appendix, a future edition should endeavor to show the reader the same techniques using those substrates. The authors end the book with a chapter that briefly explains the fundamentals of genetics and reproduction of edible mushrooms. The book's appendices contain invaluable information such as the construction of air and environmental systems, the composition of various potential substrates, data collection records and conversion tables, all of which do much to enhance its appeal to mushroom farmers. Finally, the book also includes a comprehensive and understandable glossary of key terms, a detailed bibliography, and a comprehensive index.
Essentially, the book's emphasis is on those mushroom species that can be grown with ease on compost with a few commercial species, such as shiitake, enoki, and oyster thrown in to round out the mix. You really have to look elsewhere for more detailed information on the medicinal properties of mushrooms and mushroom growing resources. Additionally, I found the absence of good, reliable economic data on mushroom cultivation, especially from the small farm or business standpoint to be lacking in both of Stamet's texts. While this text in particular was very comprehensive when it came mushroom science, I found myself looking to Stamet's Growing Gourmet Mushrooms for historical, cultural, taxonomic and medicinal information on edibles. Additionally, Growing Gourmet Mushrooms emphasized the edibles more, while this book played up the hallucinogenic mushrooms. Finally, better quality pictures, especially those in color and high resolution, would add significant value to this book.
In sum, while the average hobby cultivator just embarking on mushroom growing may find the information a bit too complicated, those looking to turn their hobby into a small farm venture will find it to be invaluable. To fully employ the techniques and methods presented in this book, the aspiring cultivator would have to invest a considerable amount of time and money. As such, I believe that this book is an excellent complement to a small farm operation. Those individuals looking to embark on hobby mushroom growing should first read Hajo Hadeler's Medicinal Mushrooms You Can Grow, and Paul Stamet's Growing Gourmet and Medicinal Mushrooms. Once the hobbyist is thoroughly familiar with the topic and the ins and outs of micro-scale (home-based) cultivation, I would strongly recommend that he or she pick up this book. As such, I see this as being more for folks who are serious about running a small farm or mushroom business, as most hobby growers would not even take the trouble to set up their own lab, or even maintain starter cultures beyond grain spawn. Thus, I recommend that this book be bought only after more basic information on mushrooms and their cultivation has been fully acquired.
