Close-up of tree bark covered with lichen (Lecanoromycetes). The bark is light gray with horizontal lines, typical of birch trees (Betula spp.). Lichen, a combination of algae and fungi, forms irregular, greenish-brown patches on the surface. The texture is rough with patches exhibiting a scaly appearance. This image highlights the symbiotic relationship lichen has with its host and the role it plays in ecosystem health by contributing to nutrient cycling.
