Common name: Oak bracket
Scientific name: Pseudoinonotus dryadeus (previously Inonotus dryadeus)
Introduction: The Oak bracket fungus is a bracket fungus that is native to the UK.
Cap: The cap of an oak bracket is broad, thick and lumpy with a pillow-like appearance. It is an orangey-brown colour and becomes more irregularly shaped as the fungus matures. When young, an amber-coloured liquid oozes from the surface, giving the cap a patterned appearance.
Tubes/Pores: Grey and similarly secrete a thick amber liquid when they are young.
Spores: Ellipsoidal and smooth.
Flesh: Felt-like when young and becomes harder in age. As the bracket fungus matures, it also develops an increasingly unpleasant smell.
Impact on Trees
The Oak bracket is parasitic (predominantly on oak trees) and belongs to the butt rot fungi group. Spores of the fungi are absorbed through cuts or wounds in the bark which in turn cause white rot and decay in the trunks of the affected trees. Despite this, however, they do play a vital role in the ecosystem of woodlands.
