Deciduous broadleaved species.
Found along the main stem and larger branching structure of the standing tree – persists on stumps and fallen tree parts.
Annual . Somewhat tough. Usually abundant. Begins as a grey pore surface with a whitish rim before developing into brackets that are zoned with browns and greys on the upper surface. Can remain resupinate on undersides of the substrate. White spore. Individually thin.
Attributed to a selective white rot of the wood. Considered saprotrophic – potentially weakly parasitic . Generally enters during earlier stages of wood dysfunction and decay. Presence on the stems and limbs / branches of standing trees signals vascular dysfunction and decay. Often associated with (local) decline on standing trees. When found on stems, further investigations may be necessary.
