In order to promote the use of wild edible mushrooms as source of nutrients and environmental marker, several experiments were performed in fruiting bodies (cap and stipe) of wild edible mushrooms which were collected from different regions of Al-Jabal Alakhdar province / Libya, including Alabraq, Alosita, Asalpiea, Ashnishen, Balanaje, Faidiyah, Marawah, Omar Mukhtar, Salantah, Sidihamri, and Werdama regions. The collections were done from September to November during 2012/2013.The analysis of mineral included determination of macro- (K, Na, Ca) and microelement (Fe, Zn, Cu, Cd, Pb)trace metal levels were determined by flame photometer and atomic absorption spectrometry.In fruiting bodies, the highest mean concentration of macroelements (dry weight basis) was found for K (26612.4), followed by Ca (3049.80) and Na (2836.85). K and Na were preferably trans located into the cap rather than the stipes. Ca, however, was often found in higher concentration in stipes than in caps. The mean microelement concentrations, across all tested fungi, were in the following order: Fe > Zn > Cu > Pb > Cd. Microelements showed different distributions, depending on the part of the fruiting body. Some were more concentrated in the caps and some in stipes and distributions varied among regions. This study proves that wild edible fungi which consumed traditionally in Al-Jabal Alakhdar province be used in well-balanced diets due to their high contents of functional minerals. Also, their low contents of heavy metals (Pb and Cd) shows that collection areas are not polluted, therefore all collected edible mushroom species can be unreservedly consumed without any health risk.
