Beech forests that make almost one half of forestry fond in Serbia have important function in biomass production and influence on environmental status. Valuable information about functioning of forest ecosystems can be provided by investigating the structure of mycorrhizal community. The aim of this study was to preliminarily describe and identify ectomycorrhizal types in natural managed beech (Fagus sylvatica L.) stands from four different sites in Serbia: Homolje Mountains, Čemernik-Ostrozub, East Boranja and Fruška gora. Samples were collected in December 2011 with soil corer of 274 ml volume at a distance of about 1m from the tree trunk. The total number of samples was 12 i. e. 3 samples per locality. Identification of fungal partner in ectomycorrhiza was obtained with morphological and anatomical characterization according to published descriptions. Different types of ectomycorrhiza were observed, described and identified. Shannon-Weaver diversity index and Species richness index were calculated. Total number of ectomycorrhizal types found in examined beech stands was 26 (8 types of ectomycorrhiza were found in the locality Fruška gora and East Boranja, 9 types in Čemernik-Ostrozub and 10 ectomycorrhizal types were observed in Homolje mountains). The preliminary results indicated high ectomycorrhiza diversity which is at the level of diversity published for other comparable beech stands in central and SE Europe. However, seasonal dynamics of ectomycorrhizal community structure should be investigated and identification of ectomycorrhizal types should be supplemented with molecular methods.
