Trametes robiniophila is a species of polypore fungus that grows on deciduous trees, particularly oak and elm. In East and Central Texas, it typically fruits from May to October, producing semicircular to fan-shaped brackets with a smooth, grayish-brown upper surface and white pores underneath. The fungus is saprotrophic, breaking down dead wood and contributing to nutrient cycling in the ecosystem. It can be found on stumps, logs, and living trees, often in shaded, humid areas such as woodland edges and stream banks.
