Looking after the research scenario in Nepal, Lichens (Jhyauu / Jhulo /Tarey /Yangben) are poorly investigated. The cause behind this is, we have limited numbers of Lichenologists working on it and very often foreign scientists made researches in Nepal. The study on lichens demand more insights on their identification procedures. Essentials chemicals, labs and recent techniques are crucial for this kind of studies. In most of the European and American countries, they have lichenological societies and they are doing good in providing training, lab studies and bringing out lots of interesting publications.
I have found very interesting weblink to know the basic procedures in identification of the lichens. I hope you will love to read it.
