Halegrapha

Halegrapha is a genus of lichen-forming fungi in the family Graphidaceae. It comprises ten species. Members of the genus form pale grey to whitish thalli that are often strongly encrusted with calcium oxalate crystals, and produce black, script-like fruiting bodies ( ) that resemble those of Graphis. Microscopic features and DNA evidence, however, place Halegrapha among a different lineage of graphid lichens allied to Phaeographis. Species are known mainly from humid forest habitats in scattered tropical and temperate localities worldwide.
