Hi all,
Can anyone identify the yellow lichen in the photo gallery? It's growing on what I believe to be Physcia adscendens, over rock. Thanks, Steve
Forgot to tell you, it's K-
wow - sure looks like a Xanthoria to me, but that would be K+. Not Candelaria, I don't think.

Well, if it is truly K-, then it pretty much has to be Candelaria, but isn't typical. Seems like the K test on Xanthoria is quite reliable and obvious.
Are all Caloplaca K+?
All of the ones with yellow or orange pigments, yes.
Why not Candelaria?
Compare C. pacifica posted in gallery.
That looks like what I see in my dissecting microscope. Thanks all!
