While milk mushrooms are a common sight during summer and fall in North America, there has until now been no single non-technical volume about the genus Lactarius. This field guide fills that gap, describing more than 250 milk mushroom species in detail, including external features, flesh, microscopic characteristics, and species habitat and distribution. The authors also provide information on the edible members of the genus. More than 85 pages of detailed photographs help make this an extremely useful guide to Lactarius for both amateur mushroom hunters and professional mycologists.
