Redonographa is a genus of lichen-forming fungi in the monogeneric family Redonographaceae. It has five species.
In 2020, Lumbsch proposed the family Redonographaceae, with the authority "(Lücking, Tehler & Lumbsch) Lumbsch, stat nov.". In botanical taxonomy, "stat. nov." is an abbreviation for the Latin term "status novus," ("new status"), and is used to indicate that an existing taxon (in this case, the subfamily Redonographoideae) has been reclassified or reassigned to a different rank or status within the taxonomic rank.
The lirellae, or fruiting structures, of Redonographa lichens can be to prominent and display a variety of forms, from unbranched to stellate (star-like) branching or even appearing in clusters. These lirellae are surrounded by a basal to almost complete . As they mature, their , or outer covering, becomes fully , arching over the hymenium and featuring short, smooth or apically warty above it. The hymenium of these lichens is clear.
Each ascus, or spore-producing sac, in Redonographa lichens contains eight . These spores are ellipsoid to oblong in shape and have 3–5 transverse septum or are somewhat with 3–5 transverse and 0–2 longitudinal septa per segment. The spores have thickened septa and lens-shaped to rounded , and they are transparent. These ascospores exhibit a negative iodine (Lugol) reaction. In terms of secondary chemistry, Redonographa lichens produce norstictic acid.
