Some lichens are growing in small patches on the vertical side of a wooden fence. A couple of species of fruticose oak moss branch up from the surface, like seaweed on the ocean of air. The one at the top is possibly a powdery blue green colored Evernia, the one bottom right a olive green lungwort lichen. There are small clumps of blue green shield lichens, with overlapping "scales" making them raised from the surface. The wood of the fence is covered with green algae, working hard to help decompose the fence.
