Eugeniella
Eugeniella is a genus of mostly leaf-dwelling (foliicolous) lichens in the family Pilocarpaceae. It contains 13 species. The genus was circumscribed in 2008 by lichenologists Robert Lücking, Emmanuël Sérusiaux, and Klaus Kalb, with "Eugeniella psychotriae" assigned as the type species. This lichen was originally called "Patellaria psychotriae" by Johannes Müller Argoviensis in 1881. The seven species that were initially included in the genus had previously been placed in the genera "Bacidia" ("sensu lato") and "Byssoloma". Several newly identified species from Australasia and Central and South America were later added. Most of the species grow on leaves, although four  of the Australasian species grow on bark. The genus name of "Eugeniella" is in honour of Eugênia Cristina Gonçalves Pereira (b.1960), a Brazilian botanist (Mycology and Lichenology) and Professor at the Federal University of Pernambuco in Recife, Brasil. Species. , Species Fungorum accepts 13 species of "Eugeniella". The species distributions given in the list below are from McCarthy and Elix 2019.
