R. coilophylla R. myriocladella R. tribulosa Ramalea is a genus of lichen-forming fungi of uncertain familial placement in the order Lecanorales.

[2] The genus was circumscribed by the Finnish lichenologist William Nylander in 1866, with Ramalea tribulosa assigned as the type species.

[4] In 1896, Müller expanded the genus by introducing the Australasian endemic species R. cochleata, drawing comparisons to Cladonia papillaria.

[5] In 2003, based on morphological and anatomical studies, Hammer proposed the creation of a new genus, Notocladonia, to accommodate R. cochleata and a newly described species, N. undulata.

[4] In 2023, molecular phylogenetics research was published that showed the genus probably belongs to the family Ramalinaceae, based on analysis of recent collections of R. coilophylla from its type locality in Brazil.
