Pholiota flavida is a type of mushroom that grows in forests and woodlands across North America. It is commonly referred to as the yellow-gilled mushroom, due to its bright yellow gills. Other synonyms for Pholiota flavida include Pholiota aurivella, Pholiota flavopurpurea, and Gymnopilus flavus. This mushroom is known for its distinctive cap, which is initially convex and then flattens out as it matures. It also has a fibrous veil on the underside of the cap that often turns into a ring as the mushroom ages. While Pholiota flavida is not considered edible, it is an important species in the ecosystem, providing nutrients for other fungi and decomposers.
