There is a dearth of books about slime moulds, specifically those targeted to the lay person not the taxonomist.
This is a great reference book for slime mould enthusiasts wanting to get more technical, arcane, and specialist knowledge. It includes photo time series, details about life cycle and morphology, information on photography, where to find them, and how to store them, and much more.
I would have happily devoured a book three times as long. Expanding the book would allow topic transitions to be more fluent and more technical sections to be elaborated on.
It is a very concise book, however this is also a benefit as it is possible to take it to the field and easily find information on morphology and images as required. It is more of a reference guide and compilation of information than one fluent book.
The pictures are really excellent and provide great references as to the diversity and types of slime mould and how drastically their appearance changes as they "mature".
I found the sections on substrate and stories about the ephemeral and sporadic nature of slime moulds very practical for a new slime mould hunter like myself.
This book is definitely a must-read / must-own for any slime mould lover.
