Pulveraria
''Chrysothrix'' is a genus of lichen-forming fungi in the family Chrysothricaceae. They are commonly called gold dust lichens or sulfur dust lichens,Field Guide to California Lichens, Stephen Sharnoff, Yale University Press, 2014, because they are bright yellow to greenish-yellow, sometimes flecked with orange, and composed entirely of powdery soredia.Brodo, I. M., S. D. Sharnoff, and S. Sharnoff. 2001. Lichens of North America. Yale University Press: New Haven. Apothecia are never present in North American specimens. They grow on bark or rocks, generally in shaded habitats. 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. ''Chrysothrix chlorina'' was traditionally used as a brown dye for wool in Scandinavia. Uphof, J. C. T. 1959. Dictionary of Economic Plants. Hafner Publishing Co.: New York.

Chrysothricaceae
Chrysotrichaceae is a family of lichenized fungi in the order Arthoniales. Member of this family have a widespread distribution, but are especially prevalent in tropical areas. "Chrysothrichaceae" and "Chrysothricaceae" are alternative spellings that have been used in some older publications; the latter was used by Alexander Zahlbruckner in the protologue publication. Both of these spellings are considered incorrect, and the current spelling has been formalised following a proposal for conservation of Chrysotrichaceae against Pulverariaceae (an earlier synonym).

Lichen
A lichen ( , ) is a composite organism that arises from algae or cyanobacteria living among filaments of multiple fungi species in a mutualistic relationship.Introduction to Lichens – An Alliance between Kingdoms . University of California Museum of Paleontology. Lichens have properties different from those of their component organisms. They come in many colors, sizes, and forms and are sometimes plant-like, but are not plants. They may have tiny, leafless branches ( fruticose); flat leaf-like structures ( foliose); grow crust ...

Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.
