Chewing gum lichen (Lecanora muralis), close up. Chewing gum lichen are a common lichen in urban areas. They grow on rock and concrete that are enriched with nitrogen; such as on bird droppings. They usually form in a rosette shape. Lichens are symbiotic organisms formed of a fungus and a photosynthetic partner (usually an alga) that mutually benefit one another. | |
