| Close-up of a lichen species, possibly of the genus *Parmotrema*, with a leaf-like, lobed structure attached to a branch. The lichen displays a pale green to brown color with circular fruiting bodies called apothecia on its surface. Its textured and irregular form contrasts with the blurred, brownish background. Lichens are symbiotic associations between fungi and algae or cyanobacteria, playing an important role in ecosystems as bioindicators and contributors to nutrient cycling. |
