The remarkable trend of revitalization of mycorrhizal mycocoenoses in the spruce forests of the Giant Mts. (Krkonoše National Park and Biosphere Reserve), Czech Republic, recognized in 1999 (Fellner and Landa 2000), is confirmed from the new collection of data obtained in 2000. The increase in abundance and frequency of mycorrhizae-forming fungi and other macromycetes at the end of the 1990s is found to be positively correlated with the distinctive reduction of sulphur dioxide emissions in the last decade. It supported the experience that fungi are highly sensitive bioindicators of air pollution and reflect the deterioration in stability of their host forest (Fellner and Pešková1995). Analysis of data indicates that the present distribution of mycorrhizal macromycetes in spruce forests in the Giant Mts. could be even greater than it was around 1960 (cf. Nespiak 1971).
