This specimen looks like the lichen version of the Dead Man’s Fingers.

For what it’s worth, I agree

The pseudocyphellae are very conspicuous on those photos, but not on your specimen, but for all I know that is acceptable variation. I wanted to pass Curtis’s comment along to you anyway, in case you hadn’t considered that species. I personally had never heard of inflated Ramalina before, so match or not, it was quite a revelation to me!

Thanks, Jason, for the hint.
However, I must say that I already knew those photographs, since they are available in the site www.irishlichens.ie that I use frequently (see here). These photos are one of the reason that led me to the proposal of Ramalina for the genus of the specimen. As you can see in the above link the species is mentioned as Ramalina siliquosa and there are to types according to the K-reaction. However, in my opinion, none of them corresponds to my specimen, because of the different organization of the thallus.

Maybe it is Ramalina

Curtis Björk suggests Ramalina portuensis, known only from Portugal and Cornwall. I can’t find much on the web, but did run across these photos:

photo one
photo two (with K+ red reaction??)

Thanks, Janson and Chris, for the comments.

At least I already know what is not.
I was only able to find some photos (by S. Sharnoff) of the species Hubbsia parishii and looks a bit different from my specimen. The chemical reactions are also different.
[Edited: My specimen lives on oak. This is another difference to Hubbsia parishii.]

remarkable lichen!

It shouldn’t be Hubbsia, since that is found only in Baja California and S California (Nash, vol 1, pp.219-220) but I am at a loss to suggest anything else. Remarkable! Ah! ,.. there is a species of Hubbsia in Chile as well that will be announced if you type Hubbsia into this query box.

Can this be Hubbsia maybe??
