The present investigation was carried out in different moist temperate forests of Garhwal Himalaya. The fruiting bodies of macrofungi were collected from these forests between July 2008 and September 2009. Frequent field visits and collections were made within the elevation range of 550-2500 msl in the districts Pauri, Tehri, Chamoli and Rudraprayag. As a result of an extensive field survey and microscopic study in laboratory, 40 taxa belonging to 11 families were identified. Two families and 2 taxa belonged to class- Ascomycetes viz: Family-Helvellaceae and Morchellaceae, and nine families and 38 taxa to class-Basidiomycetes viz: Family-Agaricaceae, Amanitaceae, Boletaceae, Cantharellaceae, Coprinaceae, Ganodermataceae Hydnagiaceae, Lycoperdaceae and Russulaceae. Some macrofungi are also being used as medicine viz: Morchella esculenta, Hydnum repandum, Agaricus campestris, Cantharellus cibarius, Coprinus comatus and Ganoderma lucidum.Keywords

An optimized Ultrasound Assisted extraction method for the extraction of Allium stracheyi Baker extract has been developed using polar (methanol) and non-polar (n-hexane) solvent at different concentrations (100%, 75%, 50% and 25%). The Bonferroni post hoc test revealed the presence of highest Total Phenolic Concentration (TPC), Total Flavonoid concentration (TFC) and DPPH per cent radical scavenging when using 25 per cent methanol at 50°C for 60 minutes. The temperature had significant effect on antioxidant activity (p<0.05) and non-significant effect on both TPC and TFC (p>0.05) whereas time showed significant effect for all (p<0.05). The antioxidant activity had positive correlation with the TPC and TFC content. The antibacterial data illustrated inhibition zones (mm) against E. coli for both hexane (100%) and methanol (100%) solvents. No inhibition zones were found against B. subtilis at the same solvent concentration. Temperature and time had no significant effect on % inhibition against the bacteria. No antibacterial activity was found against both the bacterial strains at 75 per cent, 50 per cent, 25 per cent hexane and methanol solvents. Hexane extracts showed larger inhibition zones than methanolic extracts.Keywords
