Post 6:
When we wrote this guide in 2012 this was a magnificent healthy ash
tree Fraxinus excelsior that bore many bunches of the seeds
known as
ash keys. Sadly, it may fall victim to ash dieback disease caused by
the fungus Chalara fraxinea, which was first detected in
England in the
autumn of 2012. In affected trees the leaves wilt and then go brown and
crisp, starting with the midrib or main vein. Another sign is masses of
whitish-beige small cup fungi on fallen twigs below infected trees.
