Abstract
|
|
|
|
In the past two decades, European ash trees (Fraxinus spp.) have been severely damaged due to ash dieback disease,which is caused by the fungal species Hymenoscyphus fraxineus (Chalara fraxinea in the anamorphic stage). Recent molecularphylogenetic and population genetic studies have suggested that this fungus has been introduced from Asia to Europe. During afungal survey in Korea, H. fraxineus-like apothecia were collected from fallen leaves, rachises, and petioles of Korean ash andManchurian ash trees. The morphological and ecological traits of these materials are described with the internal transcribedspacer rDNA sequence comparison of H. fraxineus strains collected from Korea, China and Japan.
