The present work describes lichen diversity in a Reserve Forest in southern Assam, northeast India, situated in the Indo-Burma biodiversity Hotspot. A total of 55 species distributed in 26 genera and 15 families were enumerated during the study. Two growth forms, crustose and foliose, were found. The crustose and foliose forms contributed 89 and 11 % of total species, respectively. Graphidaceae and Pyrenulaceae were the dominant families, which together constituted more than 50 % of populations. Pyrenula, Sarcographa and Graphis were the genera, which together accounted for approximately 30 % of the total lichen species. A total of 46 new species were encountered which were hitherto not reported from Assam state. Two species were found to be endemic to the Eastern Himalayan region and another four to the Indian region. The rich lichen diversity in a small forested area indicates the need for more such exploration in the region.
