These extremely convenient and laminated pamphlets contain an amazing amount of information, and warnings, about a number of mushrooms found along the west coast of North America. Winkler is a mushroom expert, with plenty of additional details on his website, Mushroaming.com, including information on his mushrooming eco-tours. The first portion of each pamphlet provides basic information on mushrooms as well a key to symbols for ease of identification and edibility. Most importantly, the photographs are excellent. These handy guides will be very useful to any mushroom hunter (these guides do not convert their user into an expert, and care must be exercised in the field with any discoveries).
