Phellinus chrysoloma

Description

The only fungus habitat is natural spruce woodland in mountain areas. Its biology is both saprophytic and parasitic. Living trees are infected by spores released from sporocarps through trunk or branch injuries. The fruiting bodies are perennial, growing as brackets in a linear or tiered arrangement. They are thin, with felty upper side, of cinnamon colour, later brown to blackish grey, concentrically zoned. The underside is composed of tiny dense tubes of cinnamon brown colour. A characteristic feature of the rot is formation of 5 mm long and 3 mm wide cavities, filled by the intensive wood decomposition with ochre mycelium and later with clusters of white cellulose. The wood in the last decomposition stage breaks easily along the annual rings.
