Abstract
An exhaustive study was undertaken to explore and document the lichen mycota of ecologically fascinating and biodiversity rich Angul district located in central part of Odisha. The results of the present survey revealed the occurrence of 174 species of lichens from 15 localities in the study area. It is interesting to note that out of the total species of lichen collected, 77 species were found to be new records for the state or not reported earlier. Among the different growth forms, the crustose lichens were represented with the maximum diversity with 122 species followed by 41 species of foliose, 6 species of squamulose, 4 species of leprose and a single species representing the fruticose form. Besides, the corticolous lichens were recorded with maximum diversity with 135 species followed by 39 saxicolous species. Further taxonomic studies revealed that family Caliciaceae was the dominant one represented by 21 species followed by Graphidaceae with 19, Parmeliaceae with 15, Lecanoraceae with 11, Ramalinaceae with 10 and Physciaceae and Arthoniaceae each with 9, Teloschistaceae with 8 and Verrucariacae with 7 species. Among the genus Bacidia and Graphis having largest number of species i.e. 10 followed by Lecanora and Parmotrema 9, Pertusaria 6, Amandinea, Dirinaria, Diorygma, Heterodermia, Caloplaca, Peltula and Pyxine harboured 5 species each respectively. Observations on tree substrata of all the lichen species collected indicated that the tree of Shorea could harbour 23 different lichen species followed by Mangifera with 19, Anacardium with 12 Madhuca with 8, and Diospyros with 7 numbers of lichens. The study also revealed that 2 endemic lichen species are also present in the region namely Caloplaca orissensis (Räsänen) D.D. Awasthi and Pertusaria indica Preeti Srivast. & D.D. Awasthi. Within the district the Pallahada and Panchadhara forest range are endowed with huge lichen diversity.
