Xylopsora

Xylopsora is a genus of lichen-forming fungi, belonging to the family Umbilicariaceae. The genus was established in 2013 when genetic studies showed that several scale-forming (squamulose) lichens previously grouped together were not actually closely related. Species of Xylopsora typically grow on wood, especially old or fire-scarred timber, in forests of the Northern Hemisphere. The genus includes four recognized species, some of which were only recently discovered growing high in tree canopies or detected through environmental DNA techniques....read more on Wikipedia.
