Graphis rosaeemiliae

Graphis rosae-emiliae is a species of script lichen in the family Graphidaceae. Described in 2014 from the Los Tuxtlas Biosphere Reserve in Veracruz, Mexico, this bark-dwelling lichen forms a smooth, greenish-grey crust in humid lowland rainforests, where it grows on canopy branches. The species is characterised by its unbranched, slit-like fruiting bodies (lirellae) with black, grooved lips, relatively large ascospores divided by 9–13 cross-walls, and the absence of detectable secondary metabolites....read more on Wikipedia.
