The taxonomy of this pair of species is questionable

In any one location you can convince yourself easily enough that they are good species. Just look at all the local floras which treat them separately. But now compare the description — they all contradict each other hopelessly.

I would personally call yours C. coniocraea, because I see very little cortex on the podetia, no clearly-delimited soralia, the squamules are virtually entire and rounded, and it looks like there is some soredia under the margin of the squamules. But that’s just what works for me on southeastern material and a few other scattered specimens I’ve seen. I’ve heard several of those characteristics used in various keys to prove that it’s C. ochrochlora instead!

I’ve heard that at least some eastern lichenologists have all but decided to treat them as synonyms, and that only C. ochrochlora(?) occurs in the east.

I don’t know what to think.
