Ramalina complanata (Sw.) Ach.
Thanks again, @billdodd I opened the big book up and attempted to educate myself some more. Thanks again for the ID features you pointed out. Perhaps, this may become one of the four (4) lichens I am able to ID with some confidence. @dale_kruse Hope your efforts with us will be rewarded.
