Phlebiopsis gigantea is a wood-decaying fungus that grows on coniferous trees, particularly loblolly pine. In East and Central Texas, it has been found to be a common inhabitant of freshly cut stumps and wounds, playing a role in the decomposition process. The fungus produces a brown to grayish-brown crust-like fruiting body, typically 1-5 cm in diameter, with a smooth to velvety surface. It is often associated with reduced sapwood moisture and can inhibit the growth of other fungi, including those that cause decay. Phlebiopsis gigantea has been identified in various regions of East and Central Texas, including the Piney Woods and Post Oak Savannah ecoregions.
