Endophytic fungi species composition in healthy needles of Austrian pine (Pinus nigra Arn.) was investigated at eight locations in Slovenia. Results from October 1994 and January 1995 isolations were compared with analyses of macronutrients, sulphur and lead content of the needles. About 80 species of microfungi were revealed. From the observations and measurements described it was not possible to discriminate between the effect of environmental factors and effect of air pollutants. The pollutants load of all measured elements is low and the environmental factors are very diverse. From the dendogram of isolation frequencies it seems that the age of the tree affects the species composition and frequencies of endophytes to the greatest extent.
