… A Field Guide to California Lichens (Yale), av Stephen Sharnoff, ger oss ett välbehövligt perspektiv på lavarnas liv i Kalifornien.

”The definitive guide to California’s diverse array of lichen flora, with color photographs and descriptions of over 500 species.
Lichens are among the most colorful and abundant organisms in the world. They provide food and nesting material for a wide variety of wildlife, contribute nutrients to the soil, and are indicators of both undisturbed ecosystems and clean air. They lend color and pattern to trees, shrubs, and rocks, yet most people know little about them.
This richly illustrated, authoritative guide to the lichens of California draws new attention to these striking and ecologically important organisms, which are symbionts—representing a relationship between a fungus and alga—and highlights their beauty, diversity, and value as a natural resource.”
