Foliose Lichens

What are They?

The identifying characteristic of foliose lichens is that they are leaf-like.  Unlike crustose lichens, the body of a foliose lichen is not fully attached to its substrate.  While the base of the lichen is attached, most of the body is not.  A person would be able to pull most of a foliose lichen off of a rock or branch that it is growing on. 

What Do They Look Like?
The word "foliose" means leafy.  Many foliose lichens have flat, frilly sections.  They often look like tufts of odd-shaped and odd-colored lettuce growing on a branch or rock.  Like all other lichens, the foliose type can be found in many colors like yellow, orange, black, brown, and gray.
