The chemical composition and nutritional value of two wild mushroom species namely,Amanita hemibapha (Berk.&Br.) Sacc. and Trogia cantharelloides (Mont.) Pat. wasdetermined. Nutritional evaluation includes proximate, amino acid, fatty acid and mineralanalysis. The macronutrient profile in general revealed that the wild mushrooms were richsource of carbohydrates and protein, and had low fat content. On the basis of proximateanalysis, it can be calculated that an edible portion of 100 g of these mushrooms provides, onan average, 420.083 kcal (1758.802 kJ). Among the total amino acids lysine, leucine, threonineand isoleucine were found as major essential amino acids in both the species. The fatty acidanalysis by Gas Chromatography could identify and quantify about 17 and 18 fatty acids inA. hemibapha and T. cantharelloides, respectively. Linoleic acid (34.56±0.002 g) per 100 glipid was the predominant polyunsaturated fatty acid in T. cantharelloides where oleic acid(38.82±0.005 g) per 100 g lipid was in A. hemibapha. Phosphorous and potassium was the mostabundant minerals followed by magnesium in both the species. This study contributes to thedocumentation of the nutritional composition of A. hemibapha and T. cantharelloides.
