This somewhat erect lichen is similar to Parmelia sulcata (see background, grayish-green) but not at all adherring to the bark except at the base of the lichen. It is also much lighter pale-green on the surface, but still with some white ridges, and much more finely divided branches. The reverse also varies from P. sulcata in having a rather attractive but hard to photograph (see out of focus photo) light reddish/pink to reddish/brown coloration. This lichen was so erect that the camera insisted on automatically focusing on the background bark instead of the closer lichen in question, even with my fingers providing a different focal point.
