Roccellographaceae is a family of lichen-forming fungi in the order Arthoniales.[1] It contains three genera: Dimidiographa, Fulvophyton, and Roccellographa.
The family was circumscribed by Damien Ernst and Anders Tehler in 2011 after a phylogenetic study of the Arthoniales. It is named after its type genus, Roccellographa. Before this publication, this genus was monotypic, containing the single species Roccellographa cretacea, endemic to Socotra and Somalia.[2] Three species have since been added to Roccellographa.
Genus Fulvophyton was created to contain species formerly placed in Sclerophyton, but differing from the generic type by having rounded to ellipsoid, often white pruinose ascomata, and a hyaline or pale hypothecium. Genus Dimidiographa differs from other Roccellographaceae genera in having a blackened (carbonized) excipulum (the ring-shaped layer surrounding the hymenium).[2]
