  All over the world today is developing more and more the studies concerning biochemical and physiological features of mushrooms (macromycetes) in the view to promote them as biological tools in different types of biotechnologies grace of their bioabsorption capacity for biominerals, heavy, rare or noble metals. Generally the researches are focused on the elemental content of mushrooms (Barros, 2008; Jentschke, 2000; Krupa, 1997, 2004; Yamaca, 2007). This paper is about the level of bioabsorption for some heavy metals inside fruiting body, correlated to the substrate content and pH value. It is possible that one macromycetes species to contain in a high concentration one metal, but to have a low capacity of bioabsorption, the storage level being influenced by the substrate or environmental factors. This study aim is to establish the reality concerning the bioabsorption capacity for heavy metals of following six macromycetes species: Coprinus picaceus, Coprinus cinereus, Pseudotrametes gibbosa, Lyophyllum crassifolium, Paxillus involutus and Phellinus tremulae, grown in condition of natural pH of their substrate in a forestry ecosystem of Dambovita county in south of Romania. The elemental content of biological and environmental samples was determined by Atomic Absorption Spectrometry (AAS). So, maximum concentration of cobalt was find in fruiting body of Pseudotrametes gibbosa (0,1 ppm), minimum being at fruiting body of Coprinus cinereus (0,002). It was find nickel only in fruiting body of Phellinus tremulae and Pseudotrametes gibbosa.
