Abstract

Basidiomes of 43 samples of eight Amanita species were gathered from different habitats of Hungary. The mineral composition (22 elements) was analysed by the ICP method in three independent replications, and mineral compositions found as discussed and compared. The Amanita species analysed were very different in As-, Cd-, Cr-, Mo-, Mn-, Se- and mainly in V-content. Other elements (Al, B, Ba, Ca, Co, Cu, Fe, Mg, Na, Ni, Sr, Ti, Zn) occur in the basidiomes in balanced concentrations. The K and P contents have the lowest differences. Summarizing all the data (n=43), the average mineral status of species of Amanita can be deduced. The lowest variability measured was for K and P, and the highest for chromium, nickel and vanadium.

Specific, significant accumulation was found only for vanadium, due to the previously demonstrated occurrence of a binding molecule ‘amavadine’ in the basidiomes of A. muscaria. Remarkable Cd-levels were estimated in A. pantherina and A. muscaria (11.4 and 12.3 mg kg−1D.M., respectively). The higher contents of other elements (e.g. K, practically in all species; Se in A. strobiliformis) are analytical facts but, not accumulations.

The mineral compositions of the ectomycorrhizal genus Amanita, of litter decomposing Agaricus and of wood decaying Trametes were compared. Some significant differences were found (AsAmanita<AsAgaricus; CdAmanita<CdAgaricus; CuAmanita<CuAgaricus; PAmanita<PAgaricus; KAmanita>KTrametes; PAmanita>PTrametes) but it seems that the mineral composition of the basidiomes is practically independent of the ectomycorrhizal habit. The specificities of the fungi-tree symbiotic interactions are known, and well documented (higher uptake and transport of certain elements first of all of P), however, the differences found in the mineral components are due to other factors (e.g. substrates, accumulating ability) and not to the mycorrhizal status.
