Ramalina whinrayi is a species of fruticose lichen in the family Ramalinaceae. This Australian endemic forms rigid, tufted growths up to 10 cm tall on granitic boulders and basaltic cliffs in the harsh, wind-swept environment of Bass Strait islands and northern Tasmania. It is distinguished by its distinctive internal anatomy featuring a thick outer cortex and discontinuous cord-like tissue that creates islands of medullary tissue, a structure reminiscent of the Northern Hemisphere species R. capitata.

Ramalina litorea is a species of fruticose lichen in the family Ramalinaceae. This small, maritime lichen forms minute, rigid tufts on wave-exposed coastal cliffs and is distinguished from similar species by its unique chemistry, containing evernic acid rather than the divaricatic acid found in related species. It has a disjunct distribution, being known from tropical Queensland in Australia and also from islands in the Indian Ocean including Mauritius and Rodrigues.

Ramalina caespitella is a species of rock-dwelling, fruticose lichen in the family Ramalinaceae. Described in 1986 from specimens collected on Long Island in Bass Strait, this lichen is found only in Australia, where it grows on exposed rocky cliff faces on islands in Bass Strait and along the Tasmanian coast. It forms distinctive rigid, tufted cushions that can grow up to 10 centimetres tall. The species reproduces mainly through powdery propagules, and contains characteristic lichen products including sekikaic acid.
