Clustered Bracket

Inonotus cuticularis, the clustered bracket, is a polypore fungus in the family Hymenochaetaceae that grows on living and dead hardwood trees across the northern hemisphere. The fruiting bodies are bracket-shaped, overlapping in tiered clusters, with a yellowish-brown to rusty-brown upper surface that darkens with age, and a pale to golden pore surface beneath. This species causes white heart rot in its host trees, degrading the structural integrity of trunks and major branches. It commonly attacks living oaks, beeches, and other broadleaf trees, as well as occurring on dead wood. Inonotus cuticularis is listed as Vulnerable by the IUCN, reflecting its association with old-growth and veteran trees that are increasingly rare in managed European and North American landscapes. The decline of old-growth forest and the removal of veteran trees from managed woodlands and parklands has reduced suitable habitat for many bracket fungi. Conservation of ancient and veteran trees is therefore important for maintaining populations of this and many other wood-decay fungi with similar old-growth associations.
