Ten Speed Press published several extraordinary books that are among my favourites. Arora's "Mushrooms demystified" treats a serious topic of mushroom taxonomy and identification with a light style and it is an indispensable guide to mushroom identification in western parts of North America. Another of my favourites is the monograph on feline aesthetics, "Why cats paint," an absurd gallery of paintings done by cats [see BEN # 82].

"The chanterelle book" is yet another outstanding book published by this Californian publisher. It is an English translation of a Swedish 1994 publication, translated and adapted for American audience by Dr. Eric Danell (University in Uppsala), himself an expert in the research of chanterelle. "In this book, European and North American chanterelles are discussed from the multiple perspectives of biology, ecology, geography, culinary science, culture, and linguistics," wrote the authors in the preface. The book is loaded with scientific information that is presented a very readable style. A large portion of the book is a collection recipes. Try "Stuffed Chicken Breasts with Chanterelles," if you have a chance.

The illustrations by Bo Mossberg are superb. Each plate depicts the particular species and gives few hints about its environment by including details such as pine needles, beech nuts, etc. The habitat is also illustrated by watercolours of forest interiors.

The only thing I missed in the book is a list of references. Books are usually cited in the text, but for the journal articles (such as how to produce chanterelle fruiting bodies in the greenhouse) you have to do your own literature search. If you are interested in chanterelles, you should also read "Cantharellus formosus and the Pacific Golden Chanterelle harvest in western North America" by Scott Redhead, Lorelei L. Norvell, and Eric Danell, published in Mycotaxon 65(1997): 285-322.
