Chrysothrix is a genus of lichen-forming fungi in the family Chrysotrichaceae. [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]
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]
