The image shows a close-up of a tree trunk with a group of lichen growing on it. The lichen is a light brown color and has a rough texture. The roots of the tree are visible on the left side of the image, and there is a small patch of green moss growing on the right side. The tree appears to be old and weathered, with some areas of the bark appearing rough and uneven. The fungus is growing in a circular pattern, with the largest one in the center and the smaller ones on either side.
