like returning to an old friend... on the edge of the redwoods and Douglass firs - among the tan oaks.
On living Alnus rubra bark.
One of the rarest lichens in Portugal.
Lobaria is a genus of lichens commonly known as "lungwort" or "lung moss" as their physical shape somewhat resembles a lung. Lobaria species are unusual in that they have a three-part symbiosis, containing a fungus, an alga and a cyanobacterium, the presence of the cyanobacterium allowing nitrogen fixation.
