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 iden-
tification 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 #

"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  ar-
ticles  (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 "Can-
tharellus 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.
