M/S Bishen Singh Mahendra Pal Singh Taxonomic Revision of the Lichen Genus Opegrapha Sensu Lato Roccellaceae In India by Joseph Siljo Et Al
The genus Opegrapha sensu lato in India is revised. It deals with the detailed account of Opegrapha, known so far from India, based on comprehensive investigations on the types and voucher specimens deposited in various Indian and foreign herbaria viz., AMH, ASSAM, BM, BSA, BSHC, CAL, G, GLAM, hb. AWAS, H-NYL, L, LWG, LWU, M, PBL, S, TUR and W, additional live collections and relevant literature. All the earlier erroneously identified herbarium collections were identified correctly based on the critical studies, and the specimens that required further evaluation were studied by obtaining these on loan. Information and images available in the databases of various national and international herbaria and associated libraries were critically studied.
