This lichen was found while marking boundary between the Boulder Field and Rough Ridge parking areas.
I saw several groups of lettuce lichen (I think) growing on a large boulder.
Among other things, growing on moss covered rock.
This was found growing on a tree trunk next to folios lichen and moss!
Oregon Lungwort - Thunder Creek Trail
On moss on trunk of bigleaf maple, along Titlow Hill Road, in Humboldt County California.
Lungwort is often not visible since it grows high in trees, and sometimes the branches fall, bringing it down to Earth.
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.
