Serpula himantioides is a species of fungus found on all continents except for Antarctica and is primarily found growing on moist conifer timber especially on the undersides of large logs. It causes damage to timber referred to as dry rot.
Serpula himantioides forms soft, flat, irregularly wrinkled, membranous fan-like fruit bodies up to 5 cm across. The outer edge of the fruit body is white to cream and smooth but pore-like ridges progressively appear away from the edge and these darken to orange-brown. Light to dark brown coloured spores is produced all year round on the convoluted maze of ridges.
