Phellinus chrysoloma is a polypore that lives on spruce (Picea abies). It has medium wedge-shaped perennial fruit body. Its upper surface is dark brown in colour. The edge is yellowish and hairy at a young age. The lower surface pore layer is yellowish in young specimen and brownish in the old.
Phellinus chrysoloma grows at the knots of old spruce trees or in groups of spruce bodies. It also occurs on fresh ground stems and stumps.
Phellinus chrysoloma can be confused with its relative Phellinus pini, but it is easily distinguished by its host tree.
Phellinus chrysoloma is a wood decayer that uses wood's brown lignin, leaving behind white cellulose. It is a common species in old spruce forests. In forest management, suitable substrates are formed by leaving old spruce trees as retention trees.
