Genus Oligoporus refers to a group of fungi that belong to the family Fomitopsidaceae. These mushrooms are typically found growing on decaying wood, and they range in color from white to brown. Synonyms for the genus Oligoporus include Lopharia, and Tyromyces. These mushrooms are important decomposers of dead wood, breaking down lignin and cellulose in the decaying plant material. As they decompose the wood, they release nutrients back into the ecosystem, making them a vital part of the forest ecosystem. In addition to their ecological importance, some species of Oligoporus have been used in traditional medicine to treat a range of health conditions.
