Opegraphaceae is a family of lichen-forming and lichenicolous fungi in the order Arthoniales. It was originally proposed by German lichenologist Ernst Stizenberger in 1862. It fell into disuse, but was resurrected in a molecular phylogenetic study of the order Arthoniales published in 2010. It now includes taxa that were previously referred to the family Roccellaceae, its sister group.

Opegraphaceae is a family of lichen-forming and lichenicolous fungi in the order Arthoniales. It was originally proposed by German lichenologist Ernst Stizenberger in 1862. It fell into disuse, but was resurrected in a molecular phylogenetic study of the order Arthoniales published in 2010. It now includes taxa that were previously referred to the family Roccellaceae, its sister group.
==Description== Most taxa in the family have a crustose thallus, although in rare cases it is fruticose. The lichens typically grow on bark, wood, or rocks. Some members, such as those in the genus Fouragea, grow on leaves. The family has a cosmopolitan distribution, but is predominant in tropical and semi-arid subtropical regions. The photobiont partner of Opegraphaceae is a member of the green algal genus Trentepohlia.
