Hymeno

Hymeno is a genus of fungi in the family Hymenochaetaceae. The species within this genus are commonly referred to as bristly polypores or bracket fungi. They are typically found growing on wood, often as decomposers of dead trees or as parasites on living ones. A distinctive characteristic of Hymenochaete species is the presence of stiff, bristle-like structures called setae within their hymenium, the spore-producing layer. These setae are often visible under magnification and are a key feature used in taxonomic classification.

The fruiting bodies of Hymenochaete fungi can vary in form, ranging from thin, encrusting layers to more substantial bracket or shelf-like structures. Their texture is often leathery or corky. The pore surface, where spores are released, is typically smooth and can be various shades of brown or reddish-brown. Many species are considered inedible due to their tough texture. Their ecological role as wood decomposers is significant in forest ecosystems, contributing to nutrient cycling. While some species are widespread, others have more specific host preferences or geographic distributions. Identification of Hymenochaete species often requires microscopic examination to observe the characteristic setae.
