No isidia visible on upper surface. On branches of both conifers and deciduous trees near a river.
I'm not sure what type of lichen this was. There was a lot of it hanging around though.
Unknown fungus. Found on a fir tree, if I recall correctly.
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.
