Lichens - Marija Nabernik
Species or element:
Lichens (fruticose, foliose, crustose)
Lichens give forests throughout the world their patina and create the impression of an old and stabilized ecosystem. In industrial regions this forest patina rapidly vanishes because lichens do not tolerate atmospheric pollution. One can say that lichens are indicators of clean air.
Lichens are not plants, they are composite organism that arises from algae or cyanobacteria. They may have branches (fruticose), leaf-like structures (foliose), flakes on the surface (crustose), or other growth forms. They may look plant-like and they come in many colours, sizes, and forms.
Collected specimens that are depicted on illustration are from Ljubljana where I live and from Pohorje region where I used to live. Illustration shows three different types of lichens.
