stranger to Fungi and even more so with lichens.. I need to find more about this.. :((.. but regarding the flora.. this lichen is growing on a branch of conifer..
The Kalatop sanctuary consists mostly of himalayan cedar, himalayan spruce, chir pine or Pinus roxburghii, Xylosma longifolia, Blue Pine, Himalayan Oak, Horse Chestnut, Rhododendron, Juniper, Himalayan Edelweiss, Berberis Asiatica, Aster, Daphne, Digitalis purpurea, Asparagus, Sauromatum venosum, Rubus (raspberry), Buckthorn,and these are just what comes to mind… apart from these there are innumerable varieties of mushrooms,ferns, creepers etc…. etc….., for which there is no proper documentation available, as yet…

You can usually id these things if you know the local flora, but there are too many options world-wide. Things that come to mind are: Canoparmelia (ours are weakly marked with pale maculae though), Parmelina quercina, Myelochroa aurulenta (this should have coarse pustulate soralia and move convex lobes though). If the color is off (overly blue due to reflected light from the sky), then it could even be one of the usnic-green species like Flavoparmelia. (All of these suggestions are North American genera and species, but I know at least some are cosmopolitan.)
