Lichens are organisms which result from a stable association between, at least, two component entities. In general, the dominant organism is a fungus, often called the mycobiont and it is accompanied by a photosynthetic partner (photobiont), which can be a green alga or a cyanobacterium, or both in some cases. In the Azores the list of species is still incomplete, but we estimate the occurrence of 788 taxa (10 endemic). The Fungi are less known and for now there is no available list.
Containing the 573 Lichen species and subspecies hitherto recorded from Azores with 219 species illustrated, totalling 805 photos (Updated 22nd January 2012).
