Pale at first, this unusual rather than pretty annual bracket fungus, which can appear singly or in rows or tiers, turns a distinctive blue colour as it ages.
Pine wood is the usual host of this wood-rotting fungus, although very occasionaly you may also find these hairy blue brackets on dead and decaying hardwoods such as beech or oak logs.
