A new genus, Ramalinora, in the family Ramalinaceae, is described. It
includes one species, the Australian endemic R. glaucolivida, formerly
placed in Lecanora. The morphology, anatomy, chemistry and ascomatal
development of the new genus are described. The ascus structure and as
coma ontogeny show that the genus is best placed in the Ramalinaceae,
although the thallus is crustose rather than fruticose as in other Ram
alinaceae.
