Mushrooms?are the?fleshy?and?edible?fruit bodies?of several species of macrofungi and are consumed by humans as?comestibles?for their?nutritional?value and they are occasionally consumed for their supposed?medicinal?value. Apart from these it can be grown on cheaply available different agro based wastes that can supplement the growth of these mushroom as a substrate, because these mushrooms are efficient degrader of lignocellulosic compounds and the spent obtained after the growth of mushroom can serve as good organic manure, in this context a Study was carried on to know the effect of substrates (Vegetable and flower wastes) on growth of mushroom fungi (Hypsozygous ulmarius) was studied. Here the preliminary test was done to know the substrate compatibility for growing mushroom in combination with paddy straw based on the weight loss of the substrate. The best combinations were selected for further studies of mushroom production by bag method. Use of 25 % Chrysanthemum flower waste + 75 % paddy straw as substrate showed higher mushroom yield (641.33 g/bag) and bio efficiency (128.26%) among all the substrate combinations in bag method.
