I think that Placynthium subradiatum is a candidate. Maybe there are more.

Depending on the view point.

This was “one of those days”: After a panoply of Collema spp. I observed a series of specimens for which I had no ideia about the classification.

Striking specimen, though. Would’ve loved to have know what it is!
