Cinnabar polypore

Pycnoporus cinnabarinus


The whole fruitbody of Pycnoporus cinnabarinus is bright orange. It can grow up to 10 cm across and when in bracket form projecting typically 4 to 6 cm from substrate, usually between 1 and 2 cm thick. The upper surface is rough or wrinkled, orange-red, fading with age. The margins are rounded in young specimens, which are downy or finely hairy on the upper surface and becomes more acute as the fruitbody ages. The lower surface has pale orange tubes up to 2 to 6 mm deep.


Pycnoporus cinnabarinus remains widespread, but not common, across the entire northern hemisphere in the north temperate zone, occurring throughout the majority of North America and virtually in every U.S. state. However, it has been sighted in the southern hemisphere, in parts of Australia as well as South East Asia. Pycnoporus cinnabarinus is saprophytic on hardwoods, particularly beech, birches and cherry trees.
