Synonyms[1][2]

Chrysothrix is a genus of lichen-forming fungi in the family Chrysothricaceae.[3] They are commonly called gold dust lichens or sulfur dust lichens,[4]: 253  because they are bright yellow to greenish-yellow, sometimes flecked with orange, and composed entirely of powdery soredia.[5] Apothecia are never present in North American specimens.[5]

They grow on bark or rocks, generally in shaded habitats.[5] 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.[5] Chrysothrix chlorina was traditionally used as a brown dye for wool in Scandinavia.[6]

Taxonomy

The genus was circumscribed by French botanist Camille Montagne in 1852, with Chrysothrix noli-tangere assigned as the type species.[7]

In 2012, Jack Laundon submitted a formal proposal to conserve the name Chrysothrix against Alysphaeria, published 25 years earlier than Chrysothrix, citing the need for "nomenclatural stability".[8] The proposal was accepted by the Nomenclature Committee for Fungi in 2017, who noted that Chrysothrix was already conserved against Pulveraria.[9]
