Dimidiographa Fulvophyton Roccellographa Roccellographaceae is a family of lichen-forming fungi in the order Arthoniales.

Before this publication, this genus was monotypic, containing the single species Roccellographa cretacea, endemic to Socotra and Somalia.

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).

Paraphysoids (refers to structures that form from the stretching of tissues present before the asci develop) are branched or anastomosed.
