Gibbosporina is a genus of 13 species of foliose lichens in the family Pannariaceae. It contains species that molecular phylogenetic analysis clustered together in a clade previously referred to as the "Physma"-group. Despite their morphological differences, this group shares several uniting characteristics. They have ring-like excipular margins around the thallus; strongly amyloid internal ascus structures; well-developed perispores (a colorless, often gelatinous layer that envelops a spore) that feature irregular gibbae (irregular bumps), but not verrucae (small, rounded wart-like

Psorophorus is a genus of lichenized fungi in the family Pannariaceae. It contains 2 known species. Psorophorus was described as a new genus in 2010 when it was separated from the closely related genus Psoroma. Psorophorus species differ from other species in the family in being corticolous, having adpressed squamules on a distinct, dark prothallus, lacking melanins, having a thin cortical layer and a simpler apical ascus structure.

Pannaria isidiosa is a species of foliose lichen in the family Pannariaceae, described in 2006. Found in montane forests of New South Wales, Australia, it grows on tree bark and occasionally on ferns at elevations between 1200 and 1450 metres. The lichen forms leaf-like rosettes with abundant coral-like reproductive structures known as isidia. It contains a unique combination of secondary metabolites, including pannarin and methylplacodiolic acid, as well as unidentified terpenoids. Closely related to Pannaria xanthomelana, this species is distinguished by its distinctive lemon-shaped spores

The specific epithet didyma ("in pairs"), refers to the thallus being divided into a prominent cyanobiont in addition to the dominant chlorobiont, as well as to cephalodia that are sometimes divided by the developing apothecia of chlorobionts. The lichen is known from only two locations on Réunion and Mauritius; both are tropical forests at moderate altitudes, 500–600 m (1,600–2,000 ft).

Gibbosporina boninensis is a species of foliose lichen in the family Pannariaceae. It was described as a new species in 1969 by Syo Kurokawa as Psoroma boninense. The type was collected on an andesite-rich rugged mountaintop of Mt. Tsutsuji in Chichijima, Japan. In 2016, Arve Elvebakk and Per Magnus Jørgensen transferred the taxon to the newly circumscribed genus Gibbosporina, of which it is the type species. The lichen occurs only in the isolated subtropical Bonin Islands, for which it is named.

Pannaria streimannii is a species of lichen-forming fungus in the family Pannariaceae. It is a foliose lichen with broad, leaf-like lobes, forming loose mats on stems and rocks in the high-elevation vegetation of Lord Howe Island. The species produces abundant phyllidia, small leaf-like outgrowths that act as vegetative propagules, allowing it to spread without forming sexual fruiting bodies. It was formally described in 2012 and is endemic to Lord Howe Island. It occurs at high elevation on Mount Gower and is known from only a small number of records.

Pannaria minutiphylla is a species of lichen in the family Pannariaceae, described as a new species in 2013 by Arve Elvebakk. The species is similar to Pannaria phyllidiata, but can be distinguished by its smaller phyllidia and ascospores that are elongated to ellipsoid.

Pannaria howeana is a species of foliose lichen in the family Pannariaceae. It is known only from the summit area of Mount Gower on Lord Howe Island. The lichen forms loose, leaf-like rosettes up to 10 centimetres across on tree bark in the montane vegetation, where it is distinguished by its sparse root-like attachments, distinctive lower surface with radiating fungal filaments, and a characteristic combination of chemical compounds including porphyrilic acid. It was formally described in 2012 based on a single collection from shaded Dracophyllum stems in the summit area.

The lichen contains atranorin, stictic acid, cryptostictic acid, menegazziaic acid, and constictic acid as lichen products.

Menegazzia chrysogaster is a species of foliose lichen from South America. It was described as new to science in 2001.

Hispidopannaria is a genus of lichen-forming fungi in the family Pannariaceae. It comprises two species, both found exclusively in southern South America. The genus is characterised by its large, leafy structures covered with stiff, bristle-like hairs, giving the lichen a fuzzy appearance. These lichens form symbiotic relationships with both green algae and cyanobacteria, allowing them to photosynthesise. Hispidopannaria was established as a distinct genus in 2020, based on DNA analysis that showed it to be genetically distinct from the closely related genus Pannaria. The two known species
