An enumeration of 146 species belonging to 46 genera and 24 families is provided, based on the account of lichen species published in literature, specimens preserved in herbarium and fresh collection of lichens from localities not explored earlier. Based on the available diversity and distribution pattern of lichens, an attempt has been made to map, distinguish the polluted and non-polluted localities of the study area.

The enumerated species belong to six genera and six families. The explored area showed dominance of crustose lichens while only two foliose and a single leprose species was recorded. A morpho-taxonomic note together with ecology and distribution of all the recorded lichen species as new addition to lichen flora of Uttarakhand is provided.

We studied the reproductive biology of A. rotundifolia in vitro in relation to its genetic diversity and colonizing ability. Spore germination was of Anemia type and prothallial development is of Ceratopteris type. The adult prothallus is cordate–thalloid in nature. The prothalli were hairy, bearing marginal and superficial hair. The gametangial ontogeny was observed to be favourable for both intergametophytic as well as intragametophytic selfing, but less percentage of sporophytes developed through the latter in comparison to the former. The results indicated that the gene pool of this species is moderately heterozygous, and there are chances of colonization through spores in the area of its occurrence or new habitat.
