Chrysothrix is a lichenized genus of fungi in the family Chrysothricaceae.[1] They are commonly called gold dust lichens or sulfur dust lichens,[2]: 253 because they are bright yellow to greenish-yellow, sometimes flecked with orange, and composed entirely of powdery soredia.[3] Apothecia are never present in North American specimens.[3]
They grow on bark or rocks, generally in shaded habitats.[3] They can sometimes be mistaken for sterile specimens of Chaenotheca, which usually has pinhead apothecia on tiny stalks, or Psilolechia, which usually has small, bright yellow apothecia.[3] Chrysothrix chlorina was traditionally used as a brown dye for wool in Scandinavia.[4]
