“Usnea rubicunda group” sounds well.

I already understood that the genus Usnea includes several different species. In this my first field trip to both fungi and lichen, I saw several different kind of usnea, but this one in particular called may attention precisely for the color and then I decided to include it in an observation. Fortunately it is a not so commom species. I will try to learn a bit more on this kind of lichens. Thanks for the guidance, Jason.

one of the red ones

There’s a whole complex of Usnea species with red pigment in the cortex/medulla. Yours looks a lot like what we’ve been calling U. pensylvanica in the southern Appalachians in the US, but I’d be surprised if it were the same species. You can probably get away with calling it the “Usnea rubicunda group” if you aren’t obsessed with obscure “chemospecies”. :)
