Punctelia novozelandica is a species of foliose lichen in the family Parmeliaceae. Found in New Zealand, it was formally described as a new species in 1988 by John Alan Elix and Jen Johnston. The type specimen was collected in Port Hills, Banks Peninsula (Canterbury), where it was found growing on moist rock ledges in a remnant forest. The lichen grows on both rocks and tree bark in cool temperate podocarp forests on both islands of New Zealand. It is quite similar in appearance to Punctelia subflava, but is distinguished from that species by the black thallus undersurface (it is ivory to

Parmotrema austrocetratum is a species of lichen in the family Parmeliaceae. Found in Australia and New Zealand, it was described as new to science in 1988 by John Elix and Jen Johnston. The lichen, which can grow on either bark or rock, is light grey in colour, measures 6–12 cm (2.4–4.7 in) in diameter, and is loosely attached to its substrate. It is common on trees and rocks in coastal and hinterland areas along the subtropical and tropical east coast of Australia, as well as the North Island of New Zealand.

Parmelia protosignifera is a species of foliose lichen in the large family Parmeliaceae. Found in Australasia, it was described as a new species in 1988 by lichenologists John Elix and Jen Johnston. The type specimen was collected on sheltered granite ledges in Eucalyptus woodland on the eastern slopes on Tinderry Peak in New South Wales. It has also been collected in Victoria, as well as South Island and Stewart Island of New Zealand.

Xanthoparmelia nana is a lichen species in the genus Xanthoparmelia found in Western Australia.

Xanthoparmelia colensoica is a species of lichen in the family Parmeliaceae. The species was first described in 1988 from specimens collected on acidic rock at Bainskloof Pass in South Africa's Cape Province. It forms small, firmly attached patches 1 to 2 centimetres across that are yellow-green when young but darken to greyish black with age. The lichen is distinguished by its secondary chemistry, particularly the presence of colensoic acid together with several related compounds.

Xanthoparmelia callifolioides is a foliose lichen that belongs to the genus Xanthoparmelia.

Relicina subcoronata is a species of foliose lichen-forming fungus in the family Parmeliaceae. It is a small, yellow-green, bark-dwelling lichen described in 1990 and known only from a single locality in the hinterland of northern Queensland, Australia. It is closely similar to Relicina limbata but is distinguished by its more tightly attached thallus and by the partial frilly collar on its fruiting bodies.

Relicina ramboldii is a species of saxicolous (rock-dwelling) foliose lichen in the family Parmeliaceae. Described in 1988 from Mount Baga in Queensland, this lichen forms pale greenish leaf-like patches on basalt rocks with narrow lobes edged with black hair-like projections. It rarely produces fruiting bodies, instead reproducing mainly through small outgrowths (isidia) on its upper surface. The species is known only from central Queensland, where it grows on partially shaded rock walls at moderate elevations.

Relicina columnaria is a species of lichen-forming fungus in the family Parmeliaceae. It is a yellow-green, leafy (foliose) lichen that grows on tree trunks and branches in upper montane rainforest in Sabah (Malaysia) and Papua New Guinea. The species was described in 1990 and is considered relatively rare, occurring at elevations above about 2,500 m.

Relicina clarkensis is a species of foliose lichen-forming fungus in the family Parmeliaceae. It is a small, pale green to yellow-green, rock-dwelling lichen with narrow, forking lobes edged with distinctive black, swollen-based hair-like projections. The species was described in 1990 and is known only from granite rocks in woodland in the Clarke Range of central Queensland, Australia.

Punctelia subflava is a species of foliose lichen in the family Parmeliaceae that occurs in Australia.

Punctelia nebulata is a species of foliose lichen in the family Parmeliaceae. Found in Australia, it was formally described as a new species in 1988 by lichenologists John A. Elix and Jen Johnston. The type was collected in New South Wales, on a roadside north of Gilgandra. The lichen grows on Callitris trees in semi-arid, inland regions of southern Australia. It has a foliose thallus closely attached to its substrate. The upper surface of the thallus is pale grey to mineral grey, sometimes blackening with age. The thallus is up to 8 cm (3.1 in) in diameter, made of somewhat irregularly
