Beech, hornbeam, horse chestnut, plane, and other deciduous species.
Found on dead barkless wood of standing trees (including pruning stubs) and more commonly on fallen stems and branches.
Perennial. Woody. often abundant. Usually very hairy and with a rough upper surface. Generally, an unremarkable fungus that is easily missed. Emerges a tan brown-gold to off-white and over-matures to a dulled green to olive green and brown. Flesh is medium brown. Slotted and irregular pore surface is brown with yellow to brown-gold accents (matures to a very dull greychocolate brown). Tube layer is quite deep (cross-section) and similar to to Daedalea quercina in this respect.
Trametes hirsuta (white flesh); Trametes gibbosa (white flesh).
There exists scant research on this fungus. However, it is associated with a white rot of the colonised wood. It is unlikely to be a pathogen, because it usually appears on wood already subject to the decay process (fruiting on barkless areas). Long areas covered by this fungus on a standing tree (or when found on a buttress root) may require an investigation in to the stability of said tree part, which will generally involve quantifying residual wall thickness and wood strength.
