Abstract : The Western Ghats region of Indian subcontinent is one of the globally recognized biodiversity hotspots that has an unestimated wealth of biodiversity. A survey was conducted in the Anaikatti, Attapadi, Palghat, Siruvani, Nilgiris and Kallar regions of the Western Ghats of India during 2008-10 and about 68 mushroom flora belonging to 19 genera were recorded. The seasonal occurrence of Volvariella from June-September; Calocybe from February-September; Pleurotus from June-July and November-January; Auricularia, Lentinus, Agaricus from October-January; Tricholoma during June; Ganoderma, Polyporus, Trametes from September-January and June-August; Lycoperdon during October; Termitomyces from July-October; Tramella, Mycena and Rusulla from January; Ramaria from October-November; Schizophyllum from June-October and January; Amanita from November-December and Macrolepiota during December were observed. Among the mushroom flora a wild strain of Pleurotus djamor roseus was found suitable for commercial cultivation with bioefficiency of 132 percent and cost benefit ratio of 1:2.9. The mushroom contained all essential nutrients and could be stored under room temperature for one day and under refrigerated storage for 2 days. The ITS 1 and 2 regions of the mushroom was sequenced and submitted in NCBI (Gen Bank accession No. HM107001). The diethyl ether fraction (10 percent concentration) of G. lucidum and L. edodes showed the inhibition of mycelial growth by up to 70 percent and 68.2 percent, respectively against Collectotrichum gloeosporioides, the fruit rot pathogen of Mango.
