R. menziesii is an amazing thing, isn’t it? The Sharnoffs’ photo in Lichens of North America is still the finest out there — and not from lack of competition! That species often wins the “Lichen of the Year” award for obvious reasons. But all of them are exciting finds. :)

After looking at all the Sharnoff photos of this genus I do see a real problem. It is WAY too difficult. But I enjoyed the photos nonetheless. I saw R. menziesii. If I saw that in my 10x lens I would have been excited. Really unusual looking. How many ordinary people can look at a lichen and call it Ramalina. Not many I guess, but perhaps I can now. It’s fun to be able to do that much!

Too bad, if you post such a nice photo, I’m gonna try to id it!

But this genus really has some problems. It is in extreme need of revision in the southeast. The resources out there are often contradictory, a real mess.

Brodo et al 2001 is probably the most reliable source (after the ouija board, of course), and he claims that R. willeyi (more abundant spinulose perpendicular tiny side branches) reaches its southern limit right about where you took this photo. So while that is clearly still an option, it presumably means that R. paludosa, which is shown present throughout Florida, is probably a safer bet. Besides, I can only find a couple things which might be interpreted as “spinulose side branches” in your photo.

The other two warty Ramalina reported from Florida are R. complanata (I’m ruling that out immediately, because it just looks different, and I have a lot of experience with that species) and R. denticulata. I don’t understand this latter species at all. I’m not even 100% certain it has actually been found in North America. Sources vary. Among other things, it may just be a chemotype of R. complanata (Jones 1973 says they are morphologically identical, but Brodo says R. denticulata has longer more strap-shaped lobes, blah blah blah). Who knows.

Don’t go to any trouble. Just having the genus name is good for me. I thought this shape to be interesting.
