Graphis itatiaiensis

Allographa itatiaiensis is a little-known species of lichen-forming fungus in the family Graphidaceae. Originally described in 2011 as a member of the genus Graphis, it was later transferred to Allographa in 2018 during a major reorganization of script lichen genera. The species forms thin, greenish-grey crusts on tree bark, distinguished by small spherical outgrowths and star-shaped clusters of slender, branching fruiting bodies. It is known only from humid Atlantic Forest environments in southeastern Brazil, where it grows on tree bark in shaded, moist conditions....read more on Wikipedia.
