@etc I don't see any P. glauca here, the foliose ones seem to be mostly Parmotrema with a bit of Parmelia sulcata too. Usnea is right for the fructicose one but they are often not trivial to get to species.
@carolannie I think it’s a Ramalina, I see it fairly often, but think it looks quite different without the spore discs (wrong structure name- can’t think what it is)
