BUČINOVÁ K., JANÍK R., JAMNICKÁ G., KUKLOVÁ M. (2014): Accumulation and bioconcentration factors of mineral macronutrients in representative species of macrofungi prevailing in beech-dominated forests affected by air pollution.

abstract
The contents of mineral macronutrients (phosphorus, potassium, calcium, magnesium) in forest soil samples, but also in samples of fruit bodies of dominant fungal taxa were analysed. The monitoring took place in three research plots in beech-dominated forests located near the aluminium plant at Žiar nad Hronom (Central Slovakia, Europe). The observed macrofungal taxa have different abilities of accumulating macronutrients. In forest soils, the terrestrial saprotrophic species Clitocybe nebularis accumulated phosphorus, attaining a maximum bioconcentration factor of 160 in the mineral A-horizon and 10.6 in the organic matter soil horizons (O-horizons). The ectomycorrhizal species Xerocomellus chrysenteron was rich in potassium in the A-horizon (181), but also in the O-horizons (18.8). The lignicolous saprotrophic species Polyporus varius accumulated calcium to a small extent in the A-horizon (9.36) and O-horizons (0.64), and magnesium in the A-horizon (14.2) and O-horizons (1.09).
