Opegraphales is an order of fungi that primarily includes lichenized species, which means they form symbiotic relationships with algae or cyanobacteria. These fungi are typically found in various habitats, often on tree bark or rocks, and play a crucial role in the ecosystem by contributing to soil formation and nutrient cycling. The order is characterized by its unique reproductive structures, known as apothecia, which are disc-shaped and contain spores. Opegraphales is part of the larger class of fungi called Ascomycetes, which are known for their sac-like structures that produce spores. This order showcases the diversity and ecological importance of fungi in nature.
