Lichen (Xanthoria flammea), coloured scanning electron micrograph (SEM). Lichens are organisms formed by the symbiotic association of a fungus and a green alga or cyanobacterium. The fungus grows a network of hyphae that extract nutrients from photosynthesising algae. The hyphae can also absorb minerals from rainwater or acidic digestion of the substrate. Xanthoria lichen are classified as foliose due to the appearance of branches with flattened leaf-like structures. Magnification: x20 when printed 10 centimetres wide. | |
