Roccellaceae is a family of lichenized fungi, which means they form a symbiotic relationship with algae or cyanobacteria. This family is primarily found in various habitats, including forests and rocky surfaces, where they contribute to the ecosystem by breaking down organic materials and providing food for other organisms. Members of the Roccellaceae family are characterized by their distinct fruiting bodies, known as apothecia, which can vary in shape and color. They are important indicators of environmental health and are often studied in the context of biodiversity and climate change, helping scientists understand ecosystem dynamics.
