Sign in to savePyxine is a genus of foliose lichens in the family Caliciaceae. The genus has a widespread distribution in tropical regions. It was established in 1825 by the Swedish botanist Elias Fries and is distinguished from similar lichens by its characteristic golden fluorescence under ultraviolet light due to the compound lichexanthone. These small, leaf-like lichens form radiating rosettes with narrow and tiny white lines called pseudocyphellae that act as air vents on their upper surface.
