Some of these contained gyrophoric acid

This muddled the KC test in the medulla, leading me to misidentify some as enteroxantha. Esslinger informed us that some specimens of leucoleiptes can contain variable quantities of gyrophoric acid. Such specimens have been called Physconia kurokawae, apparently.

You can really see what he was talking about when he said leucoleiptes has less continuous marginal soralia. These have obviously small discrete soralia. Look at any photo of enteroxantha. It looks more like detersa.

Good specimen

Jason, this is the one you helped me ID after consulting with Dr.Esslinger.
