Pycnoporus cinnabarinus

Pycnoporus cinnabarinus

Common Name: Cinnabar Polypore

Synonyms: Polyporus cinnabariunus

Substrate: Wood

Location: Hardwood forests

Spore Color: White

Pore Color: "Cinnabar Red"


Easily recognizeable by the growth on wood and the bright red colorations. The upper surface of the cap may fade to a pale orange then whitish color with age, but the pore surface tends to maintain a fairly vibrant red coloring.  Often found in areas outside of the forest canopy, where a bit of sun can get through.

KOH on the surface and/or flesh turns blackish-purple then eventually yellow.


Hapalopilus nidulans can be similar as the species begin to dry, but it lacks the vibrant red pore surface.
