Out of print, advised 12/10/2007. Fungi can't make their own food. They survive only because they have evolved ways of getting food from other crea tures. A fifth of them have opted for the imaginative solution of taking on algal and bacterial partners which can make food by trapping sunlight. That "lifestyle" is called a lichen. This book explains how a lichen's partners interact, shows what lichens look like on the outside and how they're built on the inside, and recounts the bizarre uses they've been put to over the centuries. illustrated with more than 300 photographs, drawings, and microscope views (most in full colour), it also explains how you can quickly and reliably photograph lichens without a camera just by scanning them into a computer with a cheap colour flatbed.
