Location

Found across the entire standing structure of the tree, and on fallen trees / tree parts and stumps.

Description

Annual. Tough. Somewhat thick, individually. Usually abundant. Often overlap and may form rosette structures. Begins as an off-white mass that develops into the pore layer beneath that does not bruise. Upper surface high varied and zoned / banded with a mix of green, brown (most frequent), grey, red, blue, or other colour. White spore.

Confused with

Bjerkandera adusta (grey pore surface).

Significance

Attributed to a selective white rot of the wood. Considered saprotrophic (a competitive saprotroph able of colonising vast areas) though may act as a facultative parasite, under certain conditions. Indicative of dysfunction. Presence on branches tends to indicate deadwood / branch decline, where not isolated to pruning stubs. Presence on stems indicative of vascular dysfunction. May signal physiological decline.
