Graphis cerradensis

Allographa cerradensis is a species of lichen-forming fungus in the family Graphidaceae. Found in Brazil, it was described as new to science in 2011 as Graphis cerradensis but in 2018 it was transferred to its current genus, Allographa. This bark-dwelling lichen forms thin, pale greenish-grey crusts with distinctive elongated fruiting bodies that snake across the surface in wavy lines. It is known only from its original discovery location in a Brazilian savanna reserve, where it grows in humid patches of dense Cerrado vegetation....read more on Wikipedia.
