Lichenology is the branch of mycology that studies the lichens, symbiotic organisms made up of an intimate symbiotic association of a microscopic alga with a filamentous fungus. Lichens are chiefly characterized by this symbiosis.
Scutula is a genus of lichenicolous fungi in the family Ramalinaceae.
Melanohalea is a genus of foliose lichens in the family Parmeliaceae. It contains 30 mostly Northern Hemisphere species that grow on bark or on wood. The genus is characterised by the presence of pseudocyphellae, usually on warts or on the tips of isidia, a non-pored epicortex and a medulla containing depsidones or lacking secondary metabolites. Melanohalea was circumscribed in 2004 as a segregate of the morphologically similar genus Melanelia, which was created in 1978 for certain brown Parmelia species. The methods used to estimate the evolutionary history of Melanohalea suggest that its diversification primarily occurred during the Miocene and Pliocene epochs.
Melanelixia is a genus of foliose lichens in the family Parmeliaceae. It contains 15 Northern Hemisphere species that grow on bark or on wood. The genus is characterized by a pored or fenestrate epicortex, and the production of lecanoric acid as the primary chemical constituent of the medulla. Melanelixia was circumscribed in 2004 as a segregate of the related genus Melanelia.
Skyttea is a genus of lichenicolous (lichen-dwelling) fungi in the family Cordieritidaceae. The genus was circumscribed in 1981 by lichenologists Martha Allen Sherwood, David L. Hawksworth, and Brian J. Coppins, with Skyttea nitschkei assigned as the type species.
Gyalecta is a genus of lichen-forming fungi in the family Gyalectaceae that contains 50 species. Gyalecta was circumscribed by lichenologist Erik Acharius in 1808. It forms associations with Trentepohlia algae.
André Aptroot is a Dutch mycologist and lichenologist.
Rolf Santesson (1916–2013) was a Swedish lichenologist and university lecturer. He was awarded the Acharius Medal in 1992 for his lifetime contributions to lichenology.
Peter Wilfred James (1930–2014) was an English botanist and lichenologist. He was a pioneer in the study of lichens as environmental indicators, especially of atmospheric pollution.
David John Galloway, FRSNZ was a biochemist, botanist, and lichenologist.
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.
Per Magnus Jørgensen is a Norwegian botanist and lichenologist, and Professor Emeritus of systematic botany at the University of Bergen. He is known for his work on the lichen families Pannariaceae and Collemataceae. Jørgensen was awarded the Acharius Medal in 2021 for his lifetime contributions to lichenology.
Brian John Coppins is a botanist and lichenologist, considered a world authority on crustose lichens and a leading expert on the genus Micarea.
Peter Crittenden is a British lichenologist. His research largely concerns the ecophysiology of lichens. Crittenden is known for using new techniques to study lichens, such as the use of 3D printing and X-ray computed tomography to study lichen structure and development. He served as the senior editor of the scientific journal The Lichenologist from the years 2000–2016; and still serves on the editorial board for the journal Fungal Ecology. Crittenden was the president of the British Lichen Society in 1998–1999, and president of the International Association for Lichenology from 2008 to 2012. He was awarded the Acharius Medal at the 10th International Mycological Congress in Bangkok in 2014, for his lifetime achievements in lichenology.
Corticifraga is a genus of lichenicolous fungi in the family Gomphillaceae. The genus was circumscribed by David Leslie Hawksworth and Rolf Santesson in 1990, with Corticifraga peltigerae assigned as the type species.
The following outline provides an overview of and topical guide to lichens.
James Donald Lawrey is a biologist, specialising in lichens. He is known for leading long-term monitoring projects, taxonomy and studies of the evolution of the fungi in lichens.
Gemmaspora is a single-species fungal genus of uncertain familial placement in the order Verrucariales. It contains Gemmaspora lecanorae, a lichenicolous (lichen-dwelling) fungus that parasitises the lichen genus Aspicilia. The genus was proposed in 2007 by David Hawksworth and Gökhan Halici to contain the fungus formerly known as Adelococcus lecanorae. This species, originally described by Roger-Guy Werner in 1963, occurs in Syria and Turkey.
Robert Lücking is a German lichenologist. He earned his master's and PhD from the University of Ulm, focusing on the taxonomy, ecology, and biodiversity of foliicolous lichens. He has received numerous awards for his work, including the Mason E. Hale Award for his doctoral thesis, the Augustin Pyramus de Candolle prize for his monograph, and the Tuckerman Award twice for his publications in the scientific journal The Bryologist. Since 2015, he has been serving as the curator of lichens, fungi, and bryophytes at the Berlin Botanical Garden and Botanical Museum. Several lichen species and a genus have been named in his honour.
Minutoexcipula is a genus of lichenicolous (lichen-dwelling) fungi of uncertain familial placement in the order Chaetothyriales. It has eight species. The genus was circumscribed in 1994 by M. Violeta Atienza Tamarit and David Leslie Hawksworth, with Minutoexcipula tuckerae assigned as the type species. The genus is characterized both by its black convex sporodochia-like conidiomata, as well as the well-differentiated exciple on these structures.
