Kumar R, Tapwal A, Pandey S, Rishi R, Borah D. 2013. Observations on arbuscular mycorrhiza associated with important edible tuberous plants grown in wet evergreen forest in Assam, India. Biodiversitas 14: 67-72. Non-timber forest products constitute an important source of livelihood for rural households from forest fringe communities across the world. Utilization of wild edible tuber plants is an integral component of their culture. Mycorrhizal associations influence the establishment and production of tuber plants under field conditions. The aim of present study is to explore the diversity and arbuscular mycorrhizal (AMF) colonization of wild edible tuber plants grown in wet evergreen forest of Assam, India. A survey was conducted in 2009-10 in Sunaikuchi, Khulahat, and Bura Mayong reserved forest of Morigaon district of Assam to determine the AMF spore population in rhizosphere soils and root colonization of 14 tuberous edible plants belonging to five families. The results revealed AMF colonization of all selected species in all seasons. The percent colonization and spore count was less in summer, moderate in winter and highest in rainy season. Seventeen species of arbuscular mycorrhizal fungi were recorded in four genera viz. Acaulospora (7 species), Glomus (5 species), Sclerocystis (3 species) and Gigaspora (2 species).

Abstract. Kumar R, Tapwal A, Pandey S, Borah RK, Borah DP, Borgohain J. 2013. Macro-fungal diversity and nutrient content of some edible mushrooms of Nagaland, India. Nusantara Bioscience 5: 1-7. The northeast region of India abounds in forest wealth, including variety of flora and fauna. The high humidity during monsoon period provides ideal atmospheric conditions for the growth of diverse group of macrofungal fruit bodies. Nagaland, the northeastern state of India is rich in biodiversity and encompasses large numbers of edible and non-edible mushroom species. Young and matured carpophores of 15 wild edible mushroom species were collected from 12 locations in different districts of Nagaland. Out of these four species belongs to family Agaricaceae, two belongs to Tricholomataceae and rest belongs to Boletaceae, Cantharellaceae, Russulaceae, Sarcoscyphaceae, Auriculariaceae, Polyporaceae, Schizophyllaceae, Pleurotaceae, and Lyophyllaceae. The selected species were analyzed for proximate analysis of nutritional values. The protein content varies from 22.50-44.93% and carbohydrates were recorded 32.43-52.07% in selected species. The documentation of wild edible mushrooms is very scanty in Northeast India. The key objective of the present study was to generate a database on macrofungal diversity, ecology, ethnomycology, utilization and nutrient status of important wild edible mushroom species of Nagaland, which forms a part of the food culture of the native peoples.
