bright orange alga Trentepohlia colonising the bark surface of an ash tree competing for space with lichen
One of the most resistant foliose lichens to air pollution. The filamentous green chlorophyte algae in the family Trentepohliaceae live on terrestrial supports, tree trunks and wet rocks or symbiotically in lichens. The filaments of Trentepohlia have a strong orange colour caused by the presence of large quantities of carotenoid pigments which mask the green of the chlorophyll. Thes orange-red pigment protects the alga against intense sunlight
