Xylographa parallela

Xylographa parallela is a species of lichen in the family Xylographaceae, and the type species of the genus Xylographa. Although it has been recorded mostly in montane and boreal forests between latitudes of about 35°N to 65°N, it is, however, the only species of Xylographa that has also been recorded from the Southern Hemisphere. It usually grows on conifer wood (very rarely on conifer bark), such as logs, snags, fenceposts, and rails....read more on Wikipedia.
