Erik Acharius was a Swedish botanist who pioneered the taxonomy of lichens and is known as the "father of lichenology". Acharius was famously the last pupil of Carl Linnaeus.
Theodor "Thore" Magnus Fries, was a Swedish botanist, lichenologist, and Arctic explorer. He was the son of the mycologist Elias Fries.
Johan Rutger Sernander was a Swedish botanist, geologist and archaeologist. He was one of the founders of the study of palynology which would later be developed by Lennart von Post, as well as a pioneer in the early Swedish natural conservation and ecology movements. He was among other societies a member of the Royal Swedish Academy of Sciences, the Royal Swedish Academy of Letters, History and Antiquities and Norwegian Academy of Science and Letters. Sernander was one of the founders of the Swedish Society for Nature Conservation in 1909, as well as its chairman during a number of the first years.
Mason Ellsworth Hale, Jr. was one of the most prolific American lichenologists of the 20th century. Many of his scholarly articles focused on the taxonomy of the family Parmeliaceae. Hale was one of the first lichen experts to incorporate secondary chemistry and technology such as computers and scanning electron microscopy into taxonomic work. Mason Hale published approximately two hundred articles and books on various aspects of lichen biology including taxonomy, anatomy, chemistry, and ecology. Hale also wrote several books aimed at education and increasing accessibility to lichens.
Hedda Maria Emerence Adelaïde Elisabeth Ekman, née Åkerhielm, credited as Elisabeth Ekman was a Swedish botanist, noted for her study of the genus Draba.
John Kenneth Bartlett was a New Zealand plant collector and botanist who specialised in mosses, liverworts, and lichens. In 1974, he found Bartlett's rātā growing south-east of Cape Reinga.
Adolf Hugo Magnusson was a Swedish naturalist who specialized in lichenology. He was a school teacher in Gothenburg from 1909 to 1948, but spent his spare time on the study of lichens. Magnusson published many monographs and floristic papers, specializing in crustose lichens. He formally described about 900 new taxa, specializing in the genera Lecidea, Lecanora, Caloplaca, and Acarospora.
Edvard August Vainio was a Finnish lichenologist. His early works on the lichens of Lapland, his three-volume monograph on the lichen genus Cladonia, and, in particular, his study of the classification and form and structure of lichens in Brazil, made Vainio renowned internationally in the field of lichenology.
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.
Gunnar Bror Fritiof Degelius was a Swedish lichenologist. Between the publications of his first and final scientific papers, Degelius had a 70-year-long research career. While he was best known for his expertise on the lichen genus Collema, he also wrote important papers on lichen biology and ecology, floristic studies of the Nordic countries and various other areas around the world, and lichen succession. Degelius described 124 new taxa, and published about 130 scientific papers. In 1992 he was one of the first to be awarded the Acharius Medal for his lifetime contributions to lichenology. Fifteen species and three genera have been named in honour of Degelius.
Emmanuël Sérusiaux is a Belgian lichenologist. His career, spanning more than four decades, has combined both lichenology research and political aspects of nature conservation. He spent several periods working as a researcher at the National Fund for Scientific Research and the University of Liège, the latter in which he accepted a faculty position as professor and head of the Plant Taxonomy and Conservation Biology unit. Sérusiaux also served for three non-consecutive appointments as Deputy Chief of Staff in the Government of Wallonia. He retired from both his academic and political positions in 2019.
Punctelia ulophylla is a species of foliose lichen in the family Parmeliaceae. It is found in Europe, where it grows on the bark of a variety of trees.
Gustaf Einar Du Rietz was a Swedish botanist and lichenologist. His research interests included plant ecology, lichen taxonomy, and biogeography. He was a leading figure in the Uppsala school of phytosociology–the study of groups of species of plants that are usually found together–and is recognised for his role in advancing this field of science and for mentoring future lichenologists. He led the Swedish Australasian Botanical Expedition of 1926–27, a seven-month research tour of various locations. He was married to Greta Sernander, who was also a lichenologist. During the expedition, Du Rietz and his wife researched the vegetation in New Zealand, Australia, and Java, focusing on mountain lichens and their potential as bioindicators for environmental conditions. They collected around 3000 specimens, contributing significantly to the study of bipolar lichens and forest ecology, despite challenges in processing all the samples upon return to Sweden. Several species have been named in his honour. In 1949, Du Rietz was elected to the Royal Swedish Academy of Sciences and contributed significantly to nature conservation efforts in Sweden.
Punctelia borreri is a species of foliose lichen in the family Parmeliaceae. It is a common and widely distributed species, occurring in tropical, subtropical, and temperate regions of Africa, Asia, Europe, North America, Oceania, and South America. The lichen typically grows on bark of deciduous trees, and less commonly on rock. Some European countries have reported increases in the geographic range or regional frequency of the lichen in recent decades, attributed alternatively to a reduction of atmospheric sulphur dioxide levels or an increase in temperatures resulting from climate change.
Pseudocyphellaria brattii is a species of foliose lichen in the family Peltigeraceae. It was described as new to science in 1997 by lichenologists David John Galloway and Gintaras Kantvilas. The type specimen was collected along Mt. Dundas Track (Tasmania), where it was found growing on dead wood in a rainforest at an altitude of 700 m (2,300 ft). The specific epithet honours Tasmanian lichenologist Geoffrey Charles Bratt, who, according to the authors, "helped to keep Australian lichenology alive during the 'lean years'".
Pseudocyphellaria glabra is a species of corticolous (bark-dwelling), foliose lichen in the family Peltigeraceae. It has a pale-green upper thallus surface, a white medulla and white pseudocyphellae.
James Murray (1923–1961) was an organic chemist at the University of Otago. He was the first twentieth-century lichenologist in New Zealand.
Ove Almborn was a Swedish lichenologist and educator. Born in Ronneby, Sweden, Almborn grew up in an environment that nurtured his early interest in botany and lichens. His early academic interests and discoveries in new lichens inspired his doctoral dissertation, which focused on the distribution and ecology of lichens in South Scandinavia. After graduating from Lund University, he was employed at its department of systematic botany, initially as a senior lecturer and later as the curator of the botanical collections at its botanical garden.
Pannaria durietzii is a species of corticolous (bark-dwelling), foliose lichen in the family Pannariaceae. Primarily found in New Zealand, it has also been reported in southeastern Australia and Tasmania, and southern Chile, indicating a broader southern hemisphere distribution.
Rhizocarpon superficiale is a species of saxicolous (rock-dwelling), crustose lichen in the family Rhizocarpaceae. It occurs in Europe and North America.
