Skeletis

Skeletis is a genus of fungi belonging to the family *Skeletocutis* within the order Polyporales. These fungi are primarily known for their wood-decaying capabilities and are commonly found in temperate and tropical regions worldwide. Members of this genus are typically saprotrophic, meaning they derive nutrients from decomposing organic matter, particularly wood.

Species within *Skeletis* are characterized by their hard, woody, and often resinous basidiocarps (fruit bodies). These structures are usually annual, with a smooth or slightly rough surface, and lack pores or tubes, distinguishing them from many other wood-decaying fungi. The basidiocarps often grow directly on the surface of dead or dying trees, contributing to the breakdown of cellulose and lignin in the wood.

One notable species is *Skeletis levis*, which is commonly found on coniferous wood in Europe and North America. These fungi play an ecological role in nutrient cycling by breaking down dead wood, facilitating the return of organic material to forest soils. They are also of interest in forestry due to their impact on tree health and timber quality.

While *Skeletis* species are not typically associated with human pathogens or significant economic losses, their presence can indicate environmental conditions such as moisture levels and the health of forest ecosystems. Research on these fungi continues to expand understanding of their ecological functions and taxonomic relationships within the broader context of wood-decaying fungi.
