Steccherinaceae

Steccherinaceae is a family of fungi belonging to the order Polyporales. These fungi are commonly known as poroid fungi, characterized by the presence of pores on their fruiting bodies, which are typically found on wood. The family was established by Czech mycologists Zdeněk Pouzar and Mirko Svrček in 1962.

The defining feature of Steccherinaceae is their hymenophore, which is poroid rather than lamellate or aculeate. The pores are typically small and circular, and the hymenium, the spore-bearing surface, lines the interior of these pores. Many species within this family are saprotrophic, meaning they obtain nutrients from dead organic matter, primarily wood, contributing to the decomposition of forest ecosystems. Some species can also be weakly parasitic.

Species in Steccherinaceae exhibit a wide range of macroscopic appearances. Their fruiting bodies can be annual or perennial, and their consistency can vary from soft and fleshy to tough and woody. Common genera within the Steccherinaceae include Steccherinum, which often produces resupinate or effused-reflexed basidiocarps with small, sharp teeth in addition to pores, and sometimes Fibroporia, known for its resupinate to effused fruiting bodies. Phylogenetic studies have helped clarify the relationships within this family, revealing a diverse group of fungi with distinct evolutionary histories. Further research continues to refine our understanding of the species diversity and ecological roles of Steccherinaceae.
