This project was funded by National Science Foundation Grant DEB-9317449 `Training for Undergraduates in Collection-based Analysis of Biological Diversity' awarded to the Field Museum of Natural History and by a University of Chicago Richter Grant. The authors would like to acknowledge Mr. Kent Orlandini (Argonne National Laboratory) for his invaluable assistance with laboratory techniques and for the use of his laboratory equipment and space. The authors would also like to thank Dr. R. Michael Miller (Argonne National Laboratory) for his advice about statistical analyses and soils, Dr. John F. Murphy (Deep Springs College) for advice concerning ectomycorrhizae, and Mr. Alexander Hruzewicz (University of Chicago) for his translations of articles from Polish and French.

N2 - This study explored the differences in metal uptake in sporocarps of ectomycorrhizae-forming fungi relative to (1) fungal species; (2) collection location; (3) differential metal uptake and variation within single-species, single-area populations; and (4) mobile metal content of soil substrate for the fungi. In addition, this study examined levels of some of the lanthanides in these mushrooms, as lanthanide uptake in higher fungi has not been quantified to date. In 1995 and 1996, sporocarps from three species of ectomycorrhizal fungi (Amanita flavorubescens, Amanita rubescens, and Russula pectinatoides) were collected from Cowles Bog, Indiana Dunes National Lakeshore (near an industrial area) and the Palos forest preserves (near a residential area). Soil was also collected from the Cowles Bog plots; metals were extracted from the soil, either with local Lake Michigan water or with nitric acid. These two extractions were meant to simulate the natural soil equilibrium concentrations of soluble metals and the maximum possible effects of any fungal chelating chemicals, respectively. An inductively coupled plasma mass spectrometer was used to analyze soil extracts and nitric acid digests of whole sporocarps for the target analytes. The metals found at elevated levels in the mushrooms included four of environmental interest (Ag, Cd, Ba, and Pb) and three lanthanides (La, Ce, and Nd). Significant differences in uptake of metals were observed between A. rubescens and R. pectinatoides, while A. rubescens and A. flavorubescens were not significantly different. With regard to location, more cadmium was found in Cowles Bog collections of A. rubescens, while Palos forest A. rubescens had more of the lanthanides and barium. Significant specimen-to-specimen variation occurred in all populations examined. Correlation analysis between pairs of trace elements within each sporocarp population revealed strong positive correlations between the lanthanides. Sporocarps concentrated more metal than was made available by the lake water extraction of soil and less metal than was made available by the nitric acid extraction of soil.
