Oak Bracket

Pseudoinonotus dryadeus

Unknown

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

The Oak Bracket faces severe decline due to the widespread loss and fragmentation of ancient oak woodlands across Europe, which has eliminated many of its host trees and suitable habitat patches. Climate change compounds these pressures by altering moisture regimes and temperature patterns that affect both the fungus and its oak hosts. Urban development and intensive forestry practices continue to remove mature oak trees, while air pollution may be weakening the symbiotic relationships this species depends upon.

Threat summary

Habitat

Oak Bracket is found exclusively on ancient and mature oak trees (Quercus species) in old-growth woodlands, parklands, and veteran tree sites across Europe. The species requires specific microclimate conditions provided by large, often centuries-old oaks with suitable bark chemistry and moisture retention.
