Ethnolichenological Notes on Lichens of Sikandra Dhar Region of North-West Himalaya
Journal Title: Asian Journal of Advanced Basic Sciences - Year 2018, Vol 6, Issue 2
Abstract
Presence of a wide range of secondary metabolites in lichen thallus is variously utilized as medicine, food, fodder, dye and spices. During the lichen floristic studies undertaken during January to September in 2018, three hundred specimens of lichens were collected from Sikandra dhar region of district Mandi (Himachal Pradesh). These specimens were then investigated morpho-chemo-taxonomically and identified. Out of these, seven species of lichens viz. Aspicilia calcarea (L.) Körb., Cladonia coniocraea (Flörke) Spreng., Dermatocarpon vellereum Zschacke, Lecanora chlarotera Nyl., Parmotrema austrosinense (Zahlbr.) Hale, Parmotrema tinctorum (Despr. ex Nyl.) Hale and Punctelia borreri (Turner) Krog are of ethnolichenological importance. Aspicilia calcarea is a source of nutrition for mites, snails and caterpillars. Cladonia coniocraea is a good source of carbohydrates and mixed with flour. Dermato-carpon vellereum has antimicrobial properties against human pathogens viz. Staphylococcus aureus, S. faecalis and Pseudomonas aeruginosa. Parmotrema tinctorum has a good food value as it contains high protein content (14%) along with amino acids, ergosterol, iron and calcium. It is also a source of brown dye for textile. Parmotrema austro-sinense is antimicrobial and has antioxidant and anti-phytopathogenic effect. Punctelia borreri is medicinal and used to cure blurred vision, bleeding from uterus, bleeding from external injuries, sores, swelling, chronic dermatitis and localized swelling.
