Recognized by sight: Tried to key it out with Moncada et al 2013 (Lichenologist 45(2): 203-263), but I can’t see enough detail of the upper surface — need to know whether it has maculae and/or pseudocyphellae and how they’re distributed… not to mention chemistry and color of medulla. Still, the genus is probably correct…

Recognized by sight: just to be thorough — if it has no maculae or pseudocyphellae, then I think it gets lumped into Lobaria s. lato…

They’re really beautiful things

I wish we had some in North America, but they’re all tropical and southern, alas. So I really appreciate the opportunity to play with one!

thank you

Thanks a lot for your help. I am out of my element with these guys. I appreciate you keying them out.

I think this has to be Lobariaceae

Solorina saccata is a closely-attached terricolous thing whose apothecia are inset into distinctive broad depressions. This is a very loosely-attached epiphyte.

The lower surface shows no pseudocyphellae or cyphellae, so I think we can rule out the green Sticta and Pseudocyphellaria immediately. That leaves Lobaria and Lobariella. I’ve never gotten a good feel for the distinction between those two genera, and indeed the paper I cited in the name proposal went to great lengths to try to resolve them phylogenetically. It’s apparently a mess. Still, Lobaria typically has gentle broad hairless mounds underneath. This specimen is flat with hairless regions associated with the margins instead. My impression is that is a Lobariella character, at least in the old taxonomy.
