Observation at a local McDonald’s, on an ornamental pear tree. The photo shows 3 lichens in particular, 1 I intended to photograph, the other I didn’t notice until after I looked at the photo at home.
Lichen 1: gray-green, with some small white raised ridges, possibly Parmelia sulcata, but a very small specimen.
Lichen 2: Unknown pine-green small lichen with black reverse, located just above the Parmelia (if that’s what it is). This lichen is less than 1/8 inch wide, growing away from the bark, somewhat fat and curved around a dark black background.
Lichen 3: yellow palmate lichen with cup-shaped structures. Cups are orange in the interior, and lined with white at the edges where still inrolled. I just made another extensive observation of this lichen, which is extremely common on these pear trees.
Lichen4: Candelaria: tiny yellow-green irregular micro lichens over everything.
