The Baeomycetales are an order of mostly lichen-forming fungi in the subclass Ostropomycetidae, in the class Lecanoromycetes. It contains 8 families, 33 genera and about 170 species. As a result of molecular phylogenetics research published in the late 2010s, several orders were folded into the Baeomycetales, resulting in a substantial increase in the number of taxa.
Trapelia is a genus of lichenized fungi in the family Trapeliaceae.
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.
Lecidella is a genus of crustose lichens in the family Lecanoraceae.
Ramboldia is a genus of lichen-forming fungi in the family Ramboldiaceae. The genus was circumscribed in 1994 by Gintaras Kantvilas and John Alan Elix. It was emended in 2008 by the inclusion of Pyrrhospora species containing the anthraquinone russulone in their apothecia and having a prosoplectenchymatous exciple. The family Ramboldiaceae was circumscribed in 2014 to contain the genus.
Chrysothrix is a genus of lichen-forming fungi in the family Chrysothricaceae. They are commonly called gold dust lichens or sulfur dust lichens, because they are bright yellow to greenish-yellow, sometimes flecked with orange, and composed entirely of powdery soredia. Apothecia are never present in North American specimens.
Tephromela is a genus of lichens in the family Tephromelataceae. There are about 25 species in this widespread genus.
Mycoblastus is a genus of crustose lichens in the family Tephromelataceae. Members of the genus are commonly called blood lichens.
Neoprotoparmelia is a genus of crustose lichens that was created in 2018. It contains 24 tropical and subtropical species that mostly grow on bark. Neoprotoparmelia is in the subfamily Protoparmelioideae of the family Parmeliaceae, along with the morphologically similar genera Protoparmelia and Maronina.
Gintaras Kantvilas is an Australian lichenologist, who earned his Ph.D in 1985 from the University of Tasmania with a thesis entitled Studies on Tasmanian rainforest lichens. He has authored over 432 species names, and 167 genera in the field of mycology.
John Alan (Jack) Elix emeritus professor in chemistry at the Australian National University, is an organic chemist who has contributed in many fields: lichenology, lichen chemotaxonomy, plant physiology and biodiversity and natural product chemistry. He has authored 2282 species names, and 67 genera in the field of mycology.
Acarospora citrina is a lichen in the family, Acarosporaceae, first described as Urceolaria citrina by Thomas Taylor in 1847. It was assigned to the genus, Acarospora, in 1913 by Alexander Zahlbruckner.
Amandinea decedens is a crustose lichen in the family Caliciaceae, first described as Lecidea decedens by Finnish botanist William Nylander in 1869. It was assigned (invalidly) the name, Amandinea decedens, in 2002 by Juliane Blaha and Helmut Mayrhofer. The name was validly published in 2016 by Blaha, Mayrhofer and Jack Elix
Trapelia coarctata is a lichenised fungus in the family, Trapeliaceae.
Constipatic acid is a fatty acid found in several lichen species. It was isolated, identified, and named by Douglas Chester and John Alan Elix in a 1979 publication. The compound was extracted from the Australian leafy lichen called Xanthoparmelia constipata, which was collected on schist boulders west of Springton, South Australia. The related compounds protoconstipatic acid and dehydroconstipatic acid were also reported concurrently. Syo Kurokawa and Rex Filson had previously detected the compounds using thin-layer chromatography when they formally described the lichen as a new species in 1975, but had not characterised them chemically.
Punctelia pseudocoralloidea is a species of foliose lichen in the family Parmeliaceae. It is found in Australia, where it grows on bark and on wood.
Punctelia subflava is a species of foliose lichen in the family Parmeliaceae that occurs in Australia.
Megalospora is a genus of lichen-forming fungi in the family Megalosporaceae.
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.
Ochrolechia insularis is a rare species of crustose lichen in the family Ochrolechiaceae. Found only on Kangaroo Island in South Australia, it forms an intricate crust on granite rocks near the sea, providing a habitat for a diverse range of species.
