Ramalinora (Ramalinaceae) — a new lichen genus from Australia

Abstract

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 ascoma ontogeny show that the genus is best placed in the Ramalinaceae, although the thallus is crustose rather than fruticose as in other Ramalinaceae.
