A lichen is a composite of a fungus, which provides structure, and a photosynthesizing algae or cyanobacterium (or both), which provides nutrients. Like other fungi they assume a wide range of fanciful forms making them very photogenic, especially at the macro level. There are over 600 species in the northwest and they are notoriously hard to classify so I would appreciate any help in refining or correcting my labels.
