Peliassaceae

Peliassaceae is a family of fungi belonging to the order Helotiales. These fungi are typically found on decaying wood, leaf litter, and other organic matter in terrestrial environments. The fruit bodies, or ascocarps, are generally small and cup-shaped, ranging in color from pale yellow to brown. Peliassaceae are saprotrophic, playing a role in nutrient cycling through the decomposition of organic material.

The taxonomy of Peliassaceae has undergone revisions due to advances in molecular phylogenetic studies. Previously, some genera were included in other families, but genetic analysis has helped to clarify their evolutionary relationships. Members of this family are characterized by their microscopic features, including the structure of their asci and ascospores. Ascospores are typically hyaline and unicellular, though variations exist within the family.

Specific genera within Peliassaceae include Peliates and Phaeosperma. The ecological significance of Peliassaceae is primarily as decomposers, contributing to the breakdown of complex organic compounds and the release of nutrients back into the ecosystem. While not typically known for causing diseases, their role in decomposition is vital for forest health and soil fertility. Further research continues to explore the diversity and ecological functions of fungi within this family.
