Ah well, some specimens are a bit more demanding than others

This one probably should be spot tested at least.

Although it doesn’t mean too much, I notice there are no observations/collections of C. caroliniana, on either this site or lichenportal.org, from Wisc.

Thanks for the tip

Yeah, there was really no lobes to be seen on this one. The twig looked like it was rolled in sugar, so-to-speak. I guess I could’ve hunted around for some other specimans, if I recall, I noticed this many times whilst walking around.

Be sure to include margins of thallus in photos

I suspect this is Canoparmelia caroliniana, but there’s no way to tell without seeing some intact lobe tips. If the specimen has overgrown the twig to such an extent that it no longer has any growing margin, then unless you plan to do chemistry, unfortunately, there’s nothing you can do.
