Abstract

In the years 2001-2004, the occurrence of parasitic fungi of plants of the genera <i>Betula</i> and <i>Salix</i> growing in the Słowiński National Park was investigated. The plant species examined included <i>B. pubescens</i>, <i>B. pendula</i>, <i>S. aurita</i>, <i>S. caprea</i>, <i>S. cinerea</i>, <i>S. fragilis</i>, and <i>S. repens</i>. Plants of the genus <i>Betula</i> were affected by 9 species of parasiting fungi. In Poland, three of them (<i>Microsphaera ornata</i> var. <i>europaea</i>, <i>Phyllactinia guttata</i>, <i>Melampsoridium betulinum</i>) occur commonly, five (<i>Asteroma leptothyrioides</i>, <i>Discula betulina</i>, <i>Fusicladium betulae</i>, <i>Phyllosticta betulina</i>, <i>Septoria betulina</i>) are rare, and <i>Septoria betulae</i>-<i>odoratae</i> has not been recorded to date. Three species, <i>Asteroma leptothyrioides</i>, <i>Fusicladium betulae</i>, <i>Phyllosticta betulina</i>), were found on new plant hosts. Plants of the genus <i>Salix</i> were attacked by 8 species of parasiting fungi. Four of them (<i>Melampsora allii</i>-<i>fragilis</i>, <i>M. caprearum</i>, <i>M. epitea</i>, <i>Uncinula adunca</i> var. <i>adunca</i>) are common in Poland, four (<i>Marssonina salicicola</i>, <i>Phyllosticta salicicola</i>, <i>Septoria salicicola</i>, <i>Trimmatostroma betulinum</i>) rarely occur here. <i>Uncinula adunca</i> var. <i>adunca</i>, <i>Marssonina salicicola</i>, <i>Phyllosticta salicicola</i>, <i>Septoria salicicola</i> and <i>Trimmatostroma betulinum</i> were associated with the plant species not reported earlier to be their hosts.
