Soil fungi communities from young Scots pine plantations affected with root rot

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
