AI-generated description
Trametes nivosa is a species of polypore fungus that grows on dead hardwood trees, particularly oak and elm. In East and Central Texas, it typically fruits in the spring and fall, producing small to medium-sized, semicircular to kidney-shaped caps with a grayish-brown to black upper surface and white pores underneath. The flesh is tough and leathery, and the spores are white to pale yellow. It can be found on stumps, logs, and fallen branches in deciduous forests and woodlands throughout the region.
