Hymenochaete

Hymenochaete is a genus of fungi in the family Hymenochaetaceae. These fungi are typically crust or bracket fungi, meaning they grow as a thin, leathery layer on wood. They are saprobic, deriving nutrients from dead organic matter, and are found worldwide in various forest ecosystems. A distinguishing feature of Hymenochaete is the presence of hyphal bridges and clamp connections, although these can be difficult to observe without microscopic examination. Their fruiting bodies are usually tough and leathery, and their pore surfaces can vary in color from reddish-brown to dark brown. Some species are annual, while others are perennial, persisting for several years. While generally not considered edible, their ecological role in wood decomposition is significant. Identification of specific species within the genus often requires microscopic analysis of spore and hyphal structures.
