Notes:
Found on fallen stick in mixed riparian woodland of pine, oak and fir. Medulla 2 layered and K-, numerous fibrils on back side of apothecium. The secondary branches are quite variable as characteristic of U. arizonica(=intermedia) but that species doesn’t have fibrils on back side of apothecium.

Add CommentLooking closer at the specimen it seems to be a very good fit and I added to the notes more I.D. characteristics. Since I don’t have a lichen key for that area but searched online and compared to other Usnea found in that area and agree that parvula could be likely. Thanks:)
and irregular (not perfectly cylindrical) branches. I used the Sonoran Flora (vol. III). Pretty hard to use without a specimen in hand, but fortunately you can rule out many species for various reasons (range, etc.), and there aren’t that many fertile species in the key to begin with.
