Trichaptum byssogenum is a species of fungus that belongs to the family Polyporaceae. It is a small to medium-sized polypore that grows on decaying wood, typically on hardwoods such as oak and elm. In East and Central Texas, it has been found growing on stumps, logs, and fallen branches, often in shaded areas with rich soil. The fungus produces annual brackets that are 1-4 cm wide, with a fuzzy or hairy underside and a smooth, gray to brown upper surface. It is a relatively common species in the region, fruiting from spring to fall, and is often found in association with other decomposer fungi.
