Species of lichen

Bathelium pruinosum is a species of corticolous (bark-dwelling) lichen in the family Trypetheliaceae. Found in Bolivia, it was formally described as a new species in 2016 by lichenologists Adam Flakus, Martin Kukwa, and André Aptroot. The type specimen was collected north of San Borja ) at an altitude of 190 m (620 ft); there, the lichen was found growing on bark in a lowland Amazon forest surrounded by Beni savanna. It contains lichexanthone, a lichen product that causes it to fluoresce yellow when lit with a long-wavelength UV light. The species epithet refers to the pruina on both the thallus and pseudostromata.
