Afzel's script lichen

Dyplolabia afzelii is a species of corticolous (bark-dwelling), script lichen in the family Graphidaceae. It has a pantropical distribution. The lichen has a thallus with colours ranging from yellow to pale olive buff, dark brownish tan, or grey, characterised by its smooth texture and considerable thickness. Its ascomata are lirelline (elongated with a slit-like opening), often raised from the thallus surface and concealed under a powdery white layer.
