with marginal soredia.

While looking up keys for Ramalina here, I found some interesting info about this genus. Arrnoor & Schumm (2008) state:¨By far the richest in strict and regional endemism is the genus Ramalina…The most striking endemism is to be found on the small (much smaller than St Helena), mostly flat island of Porto Santo near Madeira: on the old volcanic cones, no less than six endemic species of Ramalina occur, none of which have ever been found elsewhere…¨

Arrnoor, A. & F. Schumm (2008). ¨Key to Ramalina species known from Atlantic islands, with two new species from the Azores¨ Sauteria 15.

Oooh… I did find two species of Usnea (guessing this location is too far north for Protousnea) that I found nearby this Ramalina, both of course with central cord, etc. Beautiful… will post soon.

That’s exactly the one I saw down there!

I think it’s Ramalina, not Usnea. There are very few Usnea with compressed or irregular branches. Did you happen to check for the rubber band in the center? I’d be very surprised.
