Ganoderma martinicense is a species of bracket fungus that grows on trees, particularly oak and pine. In East and Central Texas, it has been found to commonly infect live oaks and other hardwoods, causing butt rot and root decay. The fungus produces large, perennial fruiting bodies with a glossy, brown to black cap and white pores underneath, typically growing at the base of infected trees. It is widely distributed in the region, with sightings reported in various counties, including Houston, Trinity, and Brazos.
