Types of ectomycorrhizae on Norway spruce were determined in soil cores from two differently polluted forest research plots from the emission zone of Sostanj Thermal Power Plant (TPP). The two plots are comparable regarding site characteristics, but are differently polluted by the emmissions from the TPP. During the vegetations season 1993, 21 soil cores were taken from each plot. In these all fine roots and ectomycorrhizal roots tips were counted and the percentages of different types were calculated. Additionally, soil mycorrhizae from underneath fungal fruit bodies were taken in order to characterize new types of ectomycorrhizae. Classical anatomical methods and molecular tools were applied for identification. 17 types of ectomycorrhizae were determined on 28443 root tips in soil cores from the heavily polluted plot (Zavodnje). The predominant types were Paxillus involutus, Xerocomus badius, Piceirhiza parallela and Piceirhiza inflata. On the less polluted plot (Mislinja) 24 different types were determined on 38502 root tips in equal volume and number of soils cores. The most frequent types were Hydnum rufescens, Amphinema byssoides, Piceirhiza oleiferans, Cenococcum geophilum and Lactarius lignyotus. Mycobioindication of forest site pollution through selective sensitive (here Hydnum rufescens), in comparison to unsensitive (here Paxillus involutus), fungal species in ectomycorrhizae is discussed.
