While monitoring the health of different ornamental and shade trees in Serbia, symptoms indicative of cypress canker disease were observed in young Cupressus sempervirens trees in the Belgrade urban area. Symptoms included tree mortality (specimens were recorded with a change in needle colour, branch decline or longitudinal bark cankers on the stems with resin exudates) and the appearance of acervuli fruiting bodies on the bark and cones. Using light microscopy, cross sections of fruiting bodies on the cankered bark and cones were examined and numerous fusoid, six-cell conidia were recorded with four inner coloured cells and two hyaline cells at the ends. Based on the unique combination of the morphological features and the infected host, this pathogen was identified as Seiridium cardinale. This is the first report of S. cardinale on the common cypress in Serbia. Possible introduction pathways and the implications of the findings are discussed.
