The edible mushroom species Agaricus campestris, Morchella esculenta, Morchella conica, P/eurotus ostreatus and Volvariel/a 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.
