In recent years, extensive mortality of ash (Fraxinus excelsior) has occurred, as a result of infection by the pathogen Hymenoscyphus pseudoalbidus. Here, at Forest Research, we are investigating the genetics and biology of the causal pathogen, but this task would be helped if we could compare it to other Hymenoscyphus sp. that occur on species other than ash.

As part of his research into identifying powdery mildew species Oliver Ellingham, a Royal Horticultural Society PhD student at the University of Reading is running a citizen science scheme. By receiving mildewed samples from participants around the UK he aims to increase our understanding of powdery mildew distribution. This harmful plant disease saps nutrients from its hosts which are often important horticultural and agricultural plants.
