But if you really want to be certain, I think you would need to rule out C. portentosa. I remember someone showing me C. portentosa ssp. pacifica at Deception Pass, so it’s around. I seem to remember it differed from C. rangiferina in being UV+ and the texture of the branches being odd, less smooth, like tufts of tomentum or something like that. A very vague memory. I think Brodo included it in LNA.
C. rangiferina-“…[branched] sometimes in fours; surface surface dull, fibrous or webby, with scattered, rounded bumps; PD+, UV-”
C. portentosa ssp. pacifica – “…[branched] commonly in threes, sometimes in twos; surface tissue (over inner translucent stereome) very thin, in scattered flocculent patches; PD-, UV+”
[compared to C. rangiferina “…more slender, & less combed to one side”]
Yes, I will pack up my lapidary UV hand-held, for when I am driving by this spot again, as it has both longwave/shorwave.
