 Title    Schwermetalle in höheren Pilzen Cadmium, Zink und Kupfer Heavy Metals in Higher Fungi Cadmium, Zinc, and Copper  
 Abstract    In a series of 190 samples, higher fungi, especially from the genus Agaricus, were analyzed by atomic absorption spectroscopy on their content of the trace metals cadmium, zinc, and copper. Cd was found to be present in high concentrations in some Agaricus species belonging to special taxonomic groups. In relation to soil concentrations, Cd is highly enriched in some Agaricus spec., the enrichment being a taxonomic criterion of special value. Among the remaining genera of higher fungi, only Leucoagaricus and Amanita showed similiar enrichment properties for cadmium. The chemically related metals Zn and Cu were found to be relative uniformely distributed in all analyzed fungi. No synergistic or antagonistic relationship between Cd and the other two metals could be detected in the mushrooms.

 Title    Cadmium — ein Wachstumsfaktor für den Schiefknolligen Anischampignon Agaricus abruptibulbus (Peck) Kauffmann Cadmium as a Growth Factor for the Mushroom Agaricus abruptibulbus (Peck) Kauffmann  
 Abstract    of Agaricus abruptibulbus, a mushroom which is known to accumulate cadmium, has been isolated and cultivated under definite conditions on agar plates or in a liquid medium in the absence and in presence of cadmium acetate. In.presence of 0.5-1.0 mg/1 Cd, mycelial growth of A. abruptibulbus is enhanced to 80% compared to the Cd-free controls, while above 4 mg Cd/1, the metal began to be inhibitory. The growth promoting effect of Cd was found to be independent from the supply of the organism with zinc. During growth in presence of Cd, an efficient uptake of the metal into the mycelium took place, a maximal 300 fold enrichment being observed with 10 mg Cd/1. Similar tests were performed with zinc, thereby showing a correlation between the uptake of both elements by the mushroom.
