Rhabdodiscus is a genus of script lichens in the family Graphidaceae. It has 36 species.

Taxonomy

The genus was circumscribed by Finnish lichenologist Edvard August Vainio in 1921. The species of this genus were previously classified in genus Stegobolus, until molecular phylogenetic analysis showed that Stegobolus and Rhabdodiscus formed two separate, distantly related clades. Rhabdodiscus was formally reinstated in 2012 to contain the formers members of the Stegobolus auberianus species group.

Description

Rhabdodiscus is characterised by having a distinctly carbonized (blackened) apothecia with thin margins that lack a felt-like pruina. In contrast, Stegobolus species have apothecia that are either uncarbonized to weakly carbonized, and have thick margins with felty pruina on the inner side.

Species

{{As of|2022|January}}, Species Fungorum accepts 36 species of Rhabdodiscus.
