A no-nonsense, fairly technical treatment of the subject. However, while it may make for dry reading, everything is easy to understand and a determined novice will not find himself lost. The book concentrates on bulk growing techniques, and the highly specialized, 'short-cut' methodologies that have become popular with some species are not in evidence. However, even a practitioner of such techniques might find this book useful for the growth parameters and the sections on trouble-shooting and disease. In case you were wondering, both edible mushrooms and interesting non-food species are covered in this work. I would warn, however, that the book may be dated and very limited with regards to it's treatment of individual strains. Overall, I'd recommend this work only to those interested in learning about bulk techniques or to determined experimenters wishing to have general technical data which they can work from or use to diagnose problems.
