Laetiporus gilbertsonii-By Megan Ralph
Laetiporus gilbertsonii, commonly known as the western sulfur shelf, is a species of bracket fungi found in the western regions of North America. It grows on living or dead hardwood trees, including oak, maple, and madrone, and is recognizable by its bright yellow to orange fruiting body.
The fruiting body of L. gilbertsonii can range in size from a few inches to over a foot in diameter, and has a distinctive shelf-like appearance with a velvety texture on top. It is edible, although some individuals may experience an allergic reaction, and is commonly used in traditional medicine for its anti-inflammatory properties.
This species is often confused with other sulfur shelf fungi, such as Laetiporus sulphureus, but can be distinguished by its more westerly distribution and smaller size of its pores on the underside of the fruiting body.
