Cladia is a genus of lichenized fungi in the family Cladoniaceae. Cladia species have a crustose primary thallus and a fruticose, secondary thallus, often referred to as pseudopodetium. The type species of the genus, Cladia aggregata, is widely distributed, occurring from South America, South Africa, Australasia and South-East Asia to southern Japan and India. Most of the other species are found in the Southern Hemisphere.
Pseudoramonia is a genus of lichenized fungi in the family Thelotremataceae.
Gregorella is a genus of lichenized fungi in the family Arctomiaceae. This is a monotypic genus, containing the single species Gregorella humida.
Myriochapsa psoromica is a species of lichen in the family Graphidaceae. Found in Brazil, it was described as new to science in 2011 as a species of Chapsa. The taxon was transferred to Myriochapsa in 2013.

Rex Bertram Filson is an Australian lichenologist who made major contributions to knowledge of lichens in Australia and Antarctica.
Rosmarie Honegger is a Swiss lichenologist and Emeritus Professor at the University of Zurich.
Melanohalea elegantula, commonly known as the elegant camouflage lichen, is a species of lichen in the family Parmeliaceae. It was first described by Alexander Zahlbruckner in 1894 as Parmelia aspidota var. elegantula. Hungarian lichenologist Ödön Szatala promoted it to full species status, as Parmelia elegantula, in 1930. Ted Esslinger transferred it to the genus Melanelia in 1978. Finally, it was assigned to the newly circumscribed genus Melanohalea in 2004.
Amphorothecium is a genus of fungi belonging to the family Myeloconidiaceae.
Trapelia thieleana is a lichenised fungus in the family, Trapeliaceae. It was first described in 2014 by the mycologists, Gintaras Kantvilas, Steven Leavitt, John Elix and Thorsten Lumbsch.
Schaereria is a genus of lichen-forming fungi. It is the sole genus in the family Schaereriaceae, which itself is the only family in the Schaereriales, an order in the subclass Ostropomycetidae of the class Lecanoromycetes.
Astrochapsa is a genus of lichen-forming fungi in the subfamily Graphidoideae of the family Graphidaceae. It has 28 species. The genus was circumscribed by Sittiporn Parnmen, Robert Lücking, and H. Thorsten Lumbsch in 2012, with Astrochapsa astroidea assigned as the type species. It was segregated from the genus Chapsa, from which it differs in having a more frequently densely corticate thallus, an apothecial margin that is mostly recurved, and the almost exclusively subdistoseptate, non-amyloid ascospores.
Rhabdodiscus is a genus of script lichens in the family Graphidaceae. It has 36 species.
Schizotrema is a genus of lichen-forming fungi in the family Graphidaceae. The genus was circumscribed in 2009 by Armin Mangold and H. Thorsten Lumbsch.
Pulchrocladia ferdinandii is a species of lichen in the family Cladoniaceae. It was first formally described as Cladonia ferdinandii by Swiss lichenologist Johannes Müller Argoviensis in 1882. The specific epithet honours German-Australian botanist Ferdinand von Mueller, who collected the type specimen near Esperance, Western Australia. Rex Filson transferred the taxon to Cladia in 1970. In 2018, it was transferred to the newly circumscribed genus Pulchrocladia.
Lepidocollema marianum is a species of cyanolichen in the family Pannariaceae. It was first scientifically described by Elias Fries in 1825 as Parmelia mariana. Per Magnus Jørgensen transferred it to the genus Lepidocollema in 2014 following a molecular phylogenetics-guided revision of the Pannariaceae.
Pseudochapsa is a genus of lichen-forming fungi in the family Graphidaceae. It has 19 species. It was circumscribed in 2012 by Sittiporn Parnmen, Robert Lücking, and Helge Thorsten Lumbsch, with Pseudochapsa dilatata as the type species. Pseudochapsa differs from Chapsa it that its excipulum is typically brown. Additionally, its ascospores are mostly discoseptate and amyloid. The generic name combines the Greek pseudo ("false") with the genus name Chapsa.
Xanthoparmelia semiviridis, also known as resurrection lichen is a foliose lichen species in the family Parmeliaceae. Its common name comes from the reaction of a dry sample to moisture. In its dry state it appears like curled-up dry leaf litter on the ground, but after rainfall the lichen will quickly recover, unfurl and become darker in colour. It is found in semi-arid areas across southern Australia and the South Island of New Zealand. The species is in decline in New Zealand because of the loss of habitat resulting from the establishment of dairy farms and vineyards in former indigenous habitat, and the deterioration of existing habitat caused by invasive species such as hawkweeds.
