Fungi colonizing overground portions of Quercus robur art presented separately for each of the following types of disease symptoms: leaves with atrophy and necrotic areas, dead branches, dead tops of branches, dead water sprouts, local necrotic areas in bark and phloem, locally dead and discoloured sapwood in debarked places, local discolorations inside sapwood, extensive nec‐rotic areas on stems, dead trees. Over 80 species of fungi were found in all, mainly from As‐comycotina and Deuteromycotina. Connected with each type of symptom there were several species of fungi which were more frequent than the remaining ones. In most cases fungi seem to be of secondary importance in development of symptoms characteristic for oak decline.
