Ecological relationships

Host of

  • King Alfred's CakesDaldinia concentrica

    So closely associated with dead Ash wood that it is practically diagnostic of the species. The relationship carries conservation urgency, Ash Dieback (Hymenoscyphus fraxineus) threatens both the host tree and this fungus across Europe.

  • Oakmoss LichenEvernia prunastri

    Also abundant on ash bark, particularly in moist western woodlands.

Parasitised by

  • European MistletoeViscum album

    Ash is a frequent mistletoe host in western European woodlands, particularly in Britain and France.
