Okay, MO key does key out to X. polycarpa, but sure does look like there’s some Xanthoria’s with sorediated terminal margins on the top photo… unless I’m totally off my rocker :) which is possible. I’ll dig up that specimen and separate out the different species.
by the way :)
Check out the description page. Thanks to Andrew K. and several other users, we’ve documented many of the species of Xanthoria on MO pretty well. (Note that X. weberi is the eastern version of X. fulva.)
