Proximate study was conducted on four edible mushrooms commonly found in farmlands in West Yagba Local Government Areas of Kogi state of Nigeria to ascertain their nutritional composition. The specimens identified as Lentinus subnudus
, Chlorophyllum molybditis
species and Pleurotus tuberregium
were analysed for protein, carbohydrate, fibre and ash ( minerals) content. The result shows that protein level ranged from 3.25mg/g in Lentinus subnudus
to 10.88mg/g in Chlorophyllum molybditis
, the carbohydrate level ranged from 1.92mg/g in Marasmus
species to 3.48mg/g in Pleurotus tuber-regium
while the ash content is between 85% to 90% and the p H tends toward neutrality in all the specimen. The high fibre content make them a good source of roughages while their low acidity and alkalinity confirms their edibility and the fact that they are not likely to contain poisonous substances which may make them toxic to human and animals after consumption. Their commercial production will be of multiple advantages to the nation.
