The mycorrhizal community in a long-term outdoor fumigation experiment was studied by counting both fruitbodies and below-ground mycorrhizas. The fruitbody populations under Scots pine showed annual successional changes which were not paralleled below ground. The trend below ground was for a continuing increase in species number with stand age. No clear effects above or below ground were attributable to fumigation treatments, but the fruitbodies of Paxillus involutus tended to occur in greater numbers in SO 2 treated plots. By contrast, below ground the mycorrhizas of this species were slightly adversely affected by SO 2 fumigation.
