Abstract:  The edible mushroom species Agaricus campestris, Morchella esculenta, Morchella conica, Pleurotus ostreatus and Volvariella volvacea were analysed for proximate composition, energy, amino acids and heavy metals. The results indicated wide variation in protein (19.44-36.60%), fats (1.20-2.60%), fibre (13.14-17.60%), ash (8.00-15.93%) and carbohydrate (31.73-50.70%). The coefficient of variation was highest for Pb arid Mn, intermediate for Cd, Cu and Fe, and least for Zn. Marked variation was also observed for essential and non-essential amino acids.
