…would be keys to North American species. It’s not quite as bad as it may seem, because the keys to genera will probably be pretty good for the most part. Actually, looking at the checklist for Bhutan again, I’m struck be how similar the flora is to the southern Appalachian Mountains in eastern North America — at least, the same genera are present in both places, and represented by similar numbers of species.
Unfortunately there are few on-line resources, even in the US. I will send you complete keys to the Ozark mountains. I can also send you keys to British Columbia. If you want I can send you my own working keys to the Smokies, as well, but I can’t guarantee their quality! But between them all — again, especially if you concentrate only on genus at first — you will probably be able to do pretty well.
But returning to the present problem: id of this particular Ramalina. Without some literature describing these Asian species I’ve never heard of, I can’t imagine how we’re going to do any better than “R. sinensis is plausible”. Here’s its description (from Lichens of North America, Brodo et al. 2001):
Thallus short and broad, 1-3.5(-5.5) cm long, 5-20(-30) mm wide, fan-shaped, undivided and almost foliose to dissected and branched, with apothecia (2-5 mm in diameter) produced at the margins; no soredia, papillae, or warts, but with strong longitudinal, often reticulate ridges.
Any online keys available.. rather difficult to get any books around here… how do I know the differences..
