Maronina

Maronina is a genus of crustose, lichen-forming fungi in the family Parmeliaceae (order Lecanorales). It currently comprises three species, with the type species, Maronina australiensis, restricted to mangrove habitats in subtropical eastern Australia. The genus was established in 1990 for species with unusually many-spored asci, but its circumscription has undergone several revisions based on DNA evidence, leading to the removal of most tropical bark-dwelling species to other genera, particularly Neoprotoparmelia. In the strict circumscription proposed from DNA evidence, Maronina is distinguished by its crustose thallus, lecanorine fruiting bodies (apothecia) with brown discs, many-spored asci, and chemistry dominated by depsides rather than depsidones....read more on Wikipedia.
