Based on the compilation of literature on lichens of Odisha (India) and other specimens and preserved in herbaria, we estimate that 252 species of lichens, belonging to 81 genera and 35 families are known from the state.Graphidaceae with 49 species is the dominant family, followed by Arthoniaceae (21), Pyrenulaceae (19), Parmeliaceae (18), Trypetheliaceae (17), Physciaceae (15), Teloschistaceae ( 14), Lecanoraceae (13), Pertusariaceae (12), Ramalinaceae (11), Caliciaceae (11), Thelotremataceae (9) and Lecidiaceae (4).Among the lichen genera Graphis is dominant with 27 species, followed by Pyrenula (16), Caloplaca (14), Pertusaria (12), Lecanora (10), Parmotrema (9), Cryptothecia (9) and Pyxine (6).Accounts of lichens are only available from 13 out of 30 districts.Of these only cursory collections from 10 districts are available, whereas Mayurbhanj, Jharsuguda and Ganjam districts are well-explored for their lichen flora.The present enumeration of more than 250 species clearly indicates a rich diversity of lichens for the state.Further exploration in other unexplored districts will add more species to the lichen flora of the state.
