Common name

Blushing bracket.

Often found on

Alder, birch, cherry, willow.

Sometimes found on

Oak, sweet chestnut, and other broadleaved species.

Location

Found on the main scaffold structure of the tree – persists on dead tree parts both standing and fallen.

Description

Perennial. Tough and woody. Occurs singularly / in groups. Can become fair-sized. Begins as a white mass before developing into a bracket – sometimes uneven. Upper surface a beige-brown, concentrically-zoned and bruises a deep red – sometimes significantly. Rimmed white. Pore surface white and elongated / maze-like. Flesh beige. Deep tube layer. Blushes to the touch. Fruit bodies become a dark grey-brown to a tinged charcoal black when senescent.

Significance

Attributed to a selective white rot of the wood. No research has been undertaken on the pathogenicity of this fungus. Often localised to deadwood and pruning wounds on living trees. Stem colonisation on living trees indicates local dysfunction of the cambium.
