A very wide range of broadleaved species.
conifers (notably larch and pine).
Found fruiting from structural roots up to the lower crown on dysfunctional areas or on dead trees and stumps.
Perennial . Grows singularly or in tiers. Tough and woody. Light chocolate brown surface. Ribbed white sometimes (usually younger specimens). Young fruiting bodies begin as white masses. White pore surface – often damaged by galls that also tunnel inside the bracket . Chocolate brown flesh. Brown spore. Upper cuticle consistently under 1mm in thickness – can be broken with thumb. Can become very large. May grow for many years.
Ganoderma australe (thicker outer crust and far more common).
Considered to be saprotrophic . Potentially a very weak parasite. Attributed with a selective white rot of wood. Presence will indicate dysfunction on living trees. There exists some confusion on the Ganoderma species, as regards pathogenicity and also where different species reside amongst a series of species complexes, with this species being considered parasitic in the Americas and also Asia. In the UK, it is generally considered to be a saprotroph.
