Abstract
The aim of work was to investigate the qualitative and quantitative characteristic features of soil fungi associations occurring in I class pine stands threatened by pathogens of tree roots in Zielonka Experimental Forest District. During the mycological analyses of soil, a total of 694 isolates of fungi representing 33 species were obtained. The most numerously represented species was Penicillium daleae which made 75% of all isolates. The second place in the ranking belonged to Penicillium janczewski amounting to 11%. In order to define the qualitative and quantitative similarity between the studied areas, a proportional inconformity was determined. The greatest similarity occurred between the associations of soil fungi obtained from site 64c and 35b.
