Air-borne ascospores of the ash dieback pathogen H. fraxineus infect ash tree leaves in summer and the pathogen continues to grow on the leaves after they have been shed in autumn. In early summer, fruiting bodies (ascocarps) form on the ash leaf stems in the leaf litter; after fertilization, mature ascocarps fire ascospores upwards into the air thereby initiating a new round of infection. European ash (Fraxinus excelsior) is very susceptible to H. fraxineus, which was probably introduced from East Asia, resulting in an epidemic of ash dieback that has swept east to west across Europe.
