ABSTRACT: A wild edible species of Pleutus cervinus mushroom was picked up for analysis for proximate, mineral and amino acid values with a view to determining these very essential components in it. The experimental sample was obtained from the savannah grassland of the Nasarawa State University campus forest in tropical Nigeria. .Proximate analysis for percentage ash, crude protein, crude fibre, and carbohydrate were determined. Amino acid analysis was done by the use of the Technicon Sequential Amino acid Analyser (TSM).while analysis for a metal was done using the Atomic Absorbtion Spectrophotometer (AAS). The proximate analysis showed that this mushroom contains 33.25% protein, 29.01 and carbohydrate and 14.12%fat among others .Amino acid analysis revealed the presence of glutamic acid with the highest concentration of 9.23 g/100 protein followed by lysine with of 8.62 g/100 protein then leucine with 6.50 g/100 protein among others while cystein concentration was lowest at 0.32g/100 protein. The concentration of Calcium was the highest among metals analysed with 227.99mg/l followed by magnesium with 79.09, with copper having 62.77mg/l.The lowest concentration of 0.090mg/l was obtained for lead. The significance of these results for a wild non domesticated species of mushroom has discussed and followed with appropriate recommendations.
