Inonotus dryadeus

Parasitic bracket fungus that colonises the heartwood of veteran oaks, causing white rot at the root collar. Mature infected trees remain standing for decades and their soft wood attracts woodpeckers.

Excavates infected oak wood weakened by Inonotus dryadeus to reach beetle larvae. Bracket-infected oaks are disproportionately represented in woodpecker foraging sites.
