Thanks for your comment, Jason. I am brand new to lichens, so I appreciate the opportunity to learn more. I’m not sure I could differentiate between the two!

The corticate granules inside the cups are right at the edge between C. chlorophaea and C. pyxidata. These ambiguous cases are very frustrating to me. I think true C. pyxidata would have large, clearly flattened, areoles inside the cups. And I think true C. chlorophaea should have at least some tiny granules verging on soredia, at least on the outside of the cups. True C. pyxidata shouldn’t have any tiny granules(?)
