Mushroom diversity in the Biligiri rangana hills of Karnataka (India)

Abstract

Evergreen forests of Biligiri rangana hills (BR hills) spread over an area of 540 sq. KM over eastern most edge of Western Ghats in Karnataka. Climatic conditions are more favorable for establishment of mushrooms and complete their life cycle. In this study, fourteen mushroom species were collected from BR hills region during monsoon (June through September 2013) with the help of Solega tribe inhabited the region since many years. Of the fourteen mushrooms, two mushrooms were identified as Ganoderma lucidum and Polyporous flabelliformis based on their phenotypic characters. The other 12 mushrooms were identified by ITS (Internal Transcribed spacer)region sequence homology as Termitomyces sp. (BRM-3)., Auricularia delicate (BRM-4), Termitomyces microcarpus (BRM-5), Amanita sp. (BRM-6), Podoscypha petalodes (BRM-7), Agaricaceae sp. (BRM-8), Macrolepiota sp.(BRM-9), Calvatia holothurioides (BRM-10), Gymnopillus crociphyllus (BRM-11), Coprinus comatus (BRM-12), Gyrodontium sacchari (BRM-13) and Clitocybeafffellea (BRM-14). Among the fourteen mushrooms, three species viz., Termito-myces species, Auricularia delicate and Termitomyces microcarpus were edible. The others were non edible/poisonous species. This study reports the diverse mushroom species as addition to biodiversity at BR hills.
