Macrolichens of the Pacific Northwest, Second Ed.
This revised and expanded edition of the first comprehensive guide to the region’s macrolichens is intended for use by beginners as well as specialists: weekend naturalists will be able to identify specimens and recognize the great diversity of lichens, while lichenologists and mycologists will gain greater knowledge of the distribution and abundance of various species. The new edition incorporates an understanding of macrolichens that has advanced tremendously in the ten years since the first edition. It includes 116 new species, many of them new to science since 1997, and 176 additional illustrations.
