Roccellaceae

Family of lichen-forming fungi

The Roccellaceae are a family of mostly lichen-forming fungi in the order Arthoniales, circumscribed by French botanist François Fulgis Chevallier in 1826. The family exhibits various growth forms, including crustose and fruticose thalli, and diverse reproductive structures. Roccellaceae species typically have apotheciate or lirellate ascomata, often with distinct blackened margins. Molecular phylogenetics studies have revealed significant genetic diversity and complex evolutionary histories within the family.
