On the second thought…

Soralia turned some color after another KC test. It looks dirty brownish. I’d stretch it if I wanted to call it orange or somewhere near that.
The method you recommended produced something, but I don’t know what to call it. It might be perceived as being greenish (or not). As far as P.detersa goes, all the descriptions talk about black lower surface, with Thomson detailing “lower surface black to tips”.

Should mean P. detersathen

You did KC test on both medulla and soralia? (Well, okay, these soralia are too dark to test. What you can do instead is scrape them off and test the medulla immediate beneath and surrounding them. Should be easier to see.)

This one doesn’t show anything with K-test or KC-test. The rhizines are squarrose, lower surface black but getting white toward the tips. It’s on boulders in the open (I think it’s dolomite), and looks totally white in the sun, although it’s dingy white in reality.
