Found fruiting along the main stem(s) and scaffold limbs and branches – includes on old pruning stubs and torn branch / limb stubs.
Perennial. Tough and woody. Resupinate on the underside of the stem / branch and forming brackets when elsewhere. Young fruit bodies develop from a mycelial web (photo e), begin orange and mature to become purple-brown on the upper surface – sometimes with green banding. New growth rings mature fruiting bodies with a gold-orange. Pore layer off-white. Can turn a mouldy blue when parasitised
Indicative of dysfunction. Localised often to stubs and the columns of wood beneath these cuts / tears. When more abundant the tree is usually in systemic decline and failure can occur. Can operate pathogenically as well as saprobically. Attributed usually with a selective white rot of the wood of the host tree though decay may begin as a soft rot.
