Pyrofomes juniperinus is a species of bracket fungus that grows on dead wood, particularly cedar and juniper trees. In East and Central Texas, it is commonly found on Eastern Red Cedar and Ashe Juniper, typically fruiting in the fall and winter months. The fungus produces woody, semi-circular to fan-shaped brackets with a reddish-brown to purple-brown upper surface and a yellowish to brownish pore surface. It is a saprotrophic species, playing a role in decomposing dead wood in these regions.
