What do you think of this Journal Article?
My observation: https://www.ispotnature.org/communities/southern-africa/view/observation/704697/twisted-foliose-lichen-knersvlakte-2012
and the FULL TEXT of New species of the lichen genus Xanthoparmelia from southern Africa (Ascomycotina: Parmeliaceae) [1986] Hale, M.E.
article on line.
See Fig 15 - do you think they match?
Hopefully we should be able to match others
Thanks to ðJ - we have a link to the Specimen Image at the Smithsonian

And thanks for the suggestion that I should set up the project - everything (well not everything yet) is coming together. I have identified three similar specimens so far.
AND added a tag so they may be viewed without too much effort - remembering that these may not be correct [Xanthoparmelia Fig16]
NOTE the first observation looks slightly paler but this may have been due to time of day.
