Impact Type: Deposition of pollutant
Key Concerns:
Devil's Bolete (Boletus satanus) grows in strict association with mature beech trees, so any factors affecting tree health may reduce its vitality. Nitrogen deposition has been shown to alter the competitive balance of soil fungi, with mycorrhizal fungi (of which Devil's Bolete is one) suffering at the expense of saprotrophic and parasitic fungi (van der Eerden et al. 1998).
Additional Comments:
Devil's Bolete is a brightly coloured fungus which is specifically associated with beech trees, and is declining throughout Europe. It is a priority BAP species, with the main sites being in south east England. Beech in these areas are suffering from detrimental effects of Ozone especially during warm, dry summers. N effects are generally detrimental for sporocarp production especially those requiring large amounts of carbon. (Wallenda & Kottke 1998). Further more general information may be found under the heading Mycorrhizal fungi.
