Leprocaulon adhaerens

Leprocaulon adhaerens is a species of leprose lichen in the family Leprocaulaceae, found in North America. It was originally described in 2007 as Lepraria adhaerens and later transferred to the genus Leprocaulon in 2013 based on molecular and morphological studies. The lichen forms a granular crust that adheres tightly to both the substrate (usually rocks) and itself, often growing over mosses and other lichens. It is chemically distinct due to its production of pannarin, zeorin, and several minor secondary metabolites. The species is known from coastal southern California, Pennsylvania, and Missouri, though its distribution may be more extensive than currently documented....read more on Wikipedia.
