Ash dieback is an emerging disease of Fraxinus excelsior in Germany. To date, economical damage is significant in nurseries, which also contribute towards spread of the disease, but damage to forests is increasing. The study presents the results of mycological and histological investigations on three hundred 3-year-old nursery ash saplings. The infection rate by the causative pathogen was determined for bark, outer and inner xylem, the pith and also separately for the above-ground portion and root system of the plants. The invasion and colonization strategy of the fungus in the woody stem was examined. In addition, the presence of soil-borne Oomycetes as possible primary or accompanying causal organisms was investigated. The results verify the dominant role of Chalara fraxinea as a causal agent of ash dieback and rule out the role of Oomycetes in the disease process. We conclude that C. fraxinea is not primarily endophytic in nature and spreads very effectively in the central stem tissues, which enables colonization of the woody stem in all three dimensions. Infections arising in the upper part of plants can thus spread extensively to lower parts.

“…Symptoms of ash dieback were also reported from Slovakia in 2008 (Kunca -personal communication); the disease was noted also in Slovenia (Ogris et al 2009) and Croatia (own observation) in 2008. Chalara fraxinea has been updated on the EPPO alert list since 2007 (EPPO 2007).…”

The causal agent of ash dieback, the hyphomycete Chalara fraxinea, was isolated from a Fraxinus excelsior cv. Pendula tree, in the Arboretum Křtiny between Křtiny and Jedovnice in Drahany Highland, and subsequently from several other locations in South Moravia in the Czech Republic. The infection was associated with severe twig dieback and symptoms of ash dieback were observed in many locations across the Czech Republic. The morphology of C. fraxinea is described and an ITS sequence is provided. Hymenoscyphus albidus, the teleomorph of C. fraxinea, is known as a quit common species from precedent mycofloristic studies provided in different areas in the Czech Republic.
