caption: The image shows a close up of a lichen-covered rock in the woods. The rock is covered in a thick layer of lichen, giving it a unique texture and color. The lichen is a light brown color and has a glossy sheen. It is clustered together on the rock, with some of the lichen overlapping each other. The texture of the rock is rough and bumpy, and it looks like it has been exposed to the elements for some time.
