First Record of Rosellinia desmazieresii on Scots Pine and its Association with Disease in Poland

Rosellinia desmazieresii was found for the ®rst time on a tree of Scots pine. It occurred on a dying tree in a mixed Scots pine-oak plantation in Poland. The fungus girdled the base of the trunk, where perithecia were produced abundantly. The fungus was evidently the cause of the treeʹs poor growth and ultimate death.
