Ash dieback disease fungus, SEM C017 / 8028
Ash dieback disease fungus. Coloured scanning electron micrograph (SEM) of the surface of a fruiting body of the fungus Chalara fraxinea, also known as Hymenoscyphus pseudoalbidus in its fruiting stage. This fungus causes disease in ash trees, leading to necrosis (tissue death) in the trees stem and dieback of the leaves and shoots. The disease can be chronic and can eventually be lethal, especially in young trees. This fungus was first found in the UK in 2012, and it is feared that the spread of the disease may affect millions of ash trees in the countrys woodlands.

EDITORS COMMENTS
This print showcases the devastating impact of Ash dieback disease fungus, a menace to ash trees in the UK. The coloured scanning electron micrograph (SEM) reveals the intricate surface of a fruiting body belonging to Chalara fraxinea, also known as Hymenoscyphus pseudoalbidus during its fruiting stage. This insidious fungus inflicts severe damage on ash trees, causing necrosis in their stems and leading to withering leaves and shoots. Young trees are especially vulnerable, facing potential lethality if infected. Discovered in 2012 within the United Kingdom, this pathogenic fungus has raised concerns about its rapid spread throughout woodland areas across the country. Experts fear that millions of ash trees may fall victim to this epidemic condition, posing a significant threat to European nature and forestry. At a magnification of x7,500 when printed at 10 centimetres wide, this SEM image provides an up-close look at the biological intricacies of this contagious fungal infection. Its vibrant colours highlight both its botanical beauty and destructive potential simultaneously. As we navigate through the challenges posed by infectious diseases in our modern world, it is crucial to understand and address threats like Ash dieback disease promptly. By studying pathogens such as Chalara fraxinea using advanced technologies like scanning electron microscopy (SEM), scientists can gain valuable insights into plant pathology and develop effective strategies for combating these lethal contagions.
