Hi John Dr Dan Blanchon confirms my view - your image is of Ramalina celastri. His comments are "R. celastri - the canaliculate branches, lack of scale and photo angle make it look a little like R. inflexa". If you wish to take this one further take it up with Dan (dblanchon@unitec.ac.nz) and Allison Knight. Not me. Cheers Peter
