Norwegian Specklebelly




Pseudocyphellaria norvegica or Norwegian Specklebelly is a lichen that has gone extinct in Wales and lives in only one location in England and five locations in Scotland. It survives in ancient woodlands on hazel, ash, sallow, elm, oak and willow. Due to their interesting symbiotic relationship between fungus and alga (with the fungus providing water and minerals and the alga photosynthesis) lichens are tough and able to survive in extreme climates. They are however very sensitive to air pollution and are sometimes used as bio-indicators of air quality. The Norwegian Specklebelly suffers from over acidity due to air pollution and this contributes to its decline in the UK. It is also at risk from deforestation, as it does not grow on young trees. This interesting lichen is mostly brown in color with white on the upper surface of the thallos. It is considered to be leafy and lobed and prefers sheltered humid locations near the coast.
