Notes: Really not sure on this ID. I havent done spot tests or really taken that close a look yet – totally open to other IDs!

But yeah, these are hard to be confident on! I had a couple that looked a lot like this (observation 103075 and observation 103078) from the Santa Monica Mts (collected on Conejo Mountain, may it alas rest in peace) which Kerry Knudsen determined as Usnea brattiae. Even with spot tests and full key from Sonoran Flora vol. 3, I failed to name it correctly. :) I would’ve called these (weakly) inflated and narrowed at the points of attachment, too. But the key to U. brattiae is a really thick axis. Maybe if you were to slice it open and check to see if it really is “hollow” inside like glabrata should be… or if it’s all filled up with a thick central cord and really stiff like brattiae should be… Another test I’ve heard used: the inflated ones (glabrata, cornuta, etc.) should give when you press a thumbnail into the “inflated” branches.
