Aulaxina

Aulaxina is a genus of lichen-forming fungi in the family Gomphillaceae. Species of Aulaxina are found predominantly in humid tropical forests across Africa, Asia, and the Americas, where they grow on the surface of living leaves, a foliicolous lifestyle. The genus is recognised by its distinctive blackish fruiting bodies, which open in a star-like or slit-like pattern, and by the small dark hairs and club-shaped reproductive structures that dot the thallus surface. The exact number of species in the genus is uncertain, as different taxonomic databases currently disagree on which names are accepted, and the boundaries of several species remain to be clarified....read more on Wikipedia.
