Lichen. Macrophotograph of the foliose (leaf-like) lichen Canomculina sp. Lichens are formed from the a symbiotic association between a fungus and an alga. The alga is contained within the hyphae (filaments) of the fungus. Lichens are slow-growing, and are usually found on stones and the bark of trees. They are sensitive to pollution, and are a good indicator of air quality. Photographed by the USGS Bee Inventory and Monitoring Lab: an organisation dedicated to identifying, cataloguing and monitoring bees and other insect species.
