Three edible wild mushrooms from Nigeria: Their proximate and mineral composition

The pilei (caps) and the stipes (stalks) of the button and early open-cap (cup) stages ofLentinus subnudus, Psathyrella atroumbonata andTermitomyces striatus were assayed separately for their proximate and mineral composition. The differences observed in the contents of some of the proximate components seem to be related to species and mushroom parts.P. atroumbonata was richest in crude and true protein,L. subnudus was richer in crude fiber, ash and carbohydrates. Mineral contents appeared to be dependent on type and parts of the mushrooms analysed. The three mushrooms were good sources of magnesium, zinc and iron.L. subnudus contained between 14.83 and 20.00 ppm of iron,P. atroumbonata contained between 20.01 and 22.09 ppm andT. striatus contained between 17.13 and 22.93 ppm of iron. The pilei ofP. atroumbonata andT. striatus are very good sources of zinc. Zinc contents for the pilei ofP. atroumbonata were 63.81 and 64.94 ppm respectively. Zinc contents forT. striatus were 90.45 and 92.49 ppm respectively.
