Lepraria is a genus of leprose (powdery) crustose lichens that grows on its substrate like patches of granular, caked up, mealy dust grains. [2] [3] Members of the genus are commonly called dust lichens. [3]: 305 [4] [5] The main vegetative body is made of patches of soredia (little balls of algae wrapped in fungus). [3]
Chrysothrix granulosa, the coastal gold dust lichen, is a brilliant yellow, powdery lichen that grows in irregular patches mostly on bark (sometimes wood and rock) in shaded dry areas of coastal western North America and western South America. [1]: 253–4 [2] In North America it is found from Mexico to as far north as British Columbia. [1]
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]
But sometimes the parts of a lichen species common name are common names of other lichen genera. For example, Psilolechia lucida, in the genus Psilolechia, is commonly called "sulphur dust lichen". [1] [2] But "sulphur lichen" refers to the genus Fulgensia, and "dust lichen" refers either to the genus Chrysothrix or the genus Lepraria. [1] [3 ...
Chrysothrix chlorina, the sulphur dust lichen, is a species of leprose (powdery) crustose lichen in the family Chrysotrichaceae. [3] Originally described scientifically by the Swedish lichenologist Erik Acharius over 200 years ago, it has been shuffled to many different genera in its taxonomic history before finally being transferred to Chrysothrix in 1981.
Lepraria finkii is a type of lichen in the genus Lepraria. [1] Its colours range from a greenish-gray to a bluish-green. The organism is generally found everywhere in the world, but more commonly found in tropical areas; it can be spotted in shaded areas on tree trunks, overtaking bryophytes, in soil banks, and in dry niches.
