Habitat
This common bracket fungus grows on dead hardwoods, including decaying stumps and fallen trunks. It is frequently associated with beech, sycamore, and horse chestnut, though it can be found on a variety of broad-leaved trees where it causes white rot. It grows solitarily, in scattered groups, or in overlapping clusters. In North America, it is often found in riparian zones, inland valleys, and foothills, particularly near urban centers.

- Whitish to yellow-cream, ranging from 3 mm to 20 mm in depth.
- Flesh
- White to pale grayish-cream. The texture is corky, tough, and leathery, becoming very hard when dry.

Edibility
This mushroom is inedible due to its tough, corky, and leathery texture. Both its odor and taste are indistinct. It can be confused with Trametes pubescens and Trametes suaveolens, which lack the characteristic extensively lumpy cap surface.
Misidentification can be fatal. Never eat a mushroom unless you're 100% sure. This information may be inaccurate. Always consult multiple sources.
Nutrient Source
