Stereum subtomentosum is a crust-like fungus that grows on dead wood, typically on deciduous trees. In East and Central Texas, it is commonly found on oak, elm, and willow species. The fruiting body is 2-5 cm wide, with a velvety to woolly texture, and a yellow-brown to golden-brown color. It has a wavy to lobed margin and a smooth to wrinkled underside. The fungus grows solitary or in small groups, often on fallen logs or stumps, and can be found year-round, but is most abundant from spring to fall.
