Tibell
Leif Tibell (born 16 November 1944) is a Swedish lichenologist and Emeritus Professor at the University of Uppsala. He is known for his expertise on calicioid lichens. He was awarded the Acharius Medal in 2012 for lifetime achievements in lichenology. Biography Tibell was born in Gothenburg, Sweden, in 1944. He developed an interest in lichens at a young age after meeting the prominent lichenologist Gunnar Degelius through the Gothenburg Botanical Garden, where they were both members. Degelius mentored Tibell, and recommended to him that he should study the subject at Uppsala University, which he did after moving there in the mid 1960s. He continued with graduate studies under the supervision of Rolf Santesson after accompanying him on a research excursion to Norway's Varanger Peninsula in 1966. Santesson was Curator of the Herbarium at the Botany Department. He was also the father of Johan Santesson, who knew Tibell through an organic chemistry research group they were both ...

Chaenothecopsis Tibellii
''Chaenothecopsis'' is a genus of about 40 species of pin lichens in the family Mycocaliciaceae. Many of the species are resinicolous, meaning they grow on conifer resin or other plant exudates. Most common host plants are trees in the genera ''Abies'', ''Picea'', and ''Tsuga''. Taxonomy The genus was circumscribed in 1927 by Finnish lichenologist Edvard August Vainio.

Caliciaceae
The Caliciaceae are a family of mostly lichen-forming fungi belonging to the class Lecanoromycetes in the division Ascomycota. Although the family has had its classification changed several times throughout its taxonomic history, the use of modern molecular phylogenetic methods have helped to establish its current placement in the order Caliciales. Caliciaceae contains 36 genera and about 600 species. The largest genus is ''Buellia'', with around 300 species; there are more than a dozen genera that contain only a single species. Most Caliciaceae grow on bark, dead wood, or rocks. Some members of this family, particularly those of the type genus, ''Calicium'', are characterized by the presence of thin-walled and short-lasting asci (spore-bearing cells) and a mazaedium, which is an accumulation of loose, maturing spores covering the surface of the fruiting body. The resulting passive spore dispersal is relatively rare amongst the Ascomycota. The mazaedium, usually black, either ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rolf Santesson
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. Early life and education Santesson was born in 1916 in Trollhättan, Sweden. He was already collecting lichens as a student, investigating the lichen flora of the table mountains of Halleberg and Hunneberg near his home. He entered the University of Uppsala in the 1930s to study botany. It was here he met the flamboyant Professor of Plant Ecology and lichen taxonomist Gustaf Einar Du Rietz, with whom he undertook studies on crustose lichens found on shoreline rocks of Swedish lakes. This work led to a lifelong interest in marine lichens. He earned a B.Sc. in 1938, followed by an M.Sc. in 1939. That same year, joined by zoologist Christian Olrog, Santesson embarked on what was supposed to be an eight-month research excursion in Patagonia (southern South America). Because of the outbreak of war, which made sea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pin Lichen
Lichens are wikt:composite, composite organisms made up of multiple species: a fungus, fungal partner, one or more photosynthetic partners, and sometimes a yeast, basidiomycete yeast. They are regularly grouped by their external appearance – a characteristic known as their growth form. Lichenologists have described a dozen of these forms: areolate, byssoid, calicioid, cladoniform, crustose, filamentous, foliose, fruticose, gelatinous, leprose, placoidioid and squamulose. Of these, crustose, foliose and fruticose are the most commonly encountered. With the exception of calicioid lichens, growth forms are based on the appearance of the thallus, which is the vegetative (non-reproductive) part of the lichen. In most species, this form is determined by the lichen's fungal partner, though in a small number, it is instead the photobiont that determines the lichen's morphology. In some growth forms, the outermost layer of the thallus consists of tightly woven fungal . This layer, known ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Acharius Medal
__NOTOC__ The Acharius Medal is awarded by the International Association for Lichenology (IAL) for lifetime achievement in lichenology. The organization resolved at its 1990 meeting that it would simultaneously honor professional achievement and commemorate Erik Acharius (recognized as the "Father of Lichenology") by presenting a medal in his name. The first Acharius Medal was made in 1846 by the Royal Swedish Mint for the Royal Swedish Academy of Sciences, although the original purpose for that medal is not known. Because the Swedish Mint still had the dies for the original medal, the IAL arranged for new medals to be made. The first of the new medals were awarded in that same year (1992) at the association's congress in Båstad, Sweden. The medal The medal is silver, with Acharius' profile on one side and the recipient's name on the other. Recipients Source: 2021: * Per Magnus Jørgensen * James D.

Atla Tibelliorum
''Atla tibelliorum'' is a rare species of saxicolous (rock-dwelling) in the family Verrucariaceae. Found in Finland and the United States, it was formally described as a new species in 2016 by Juha Pykälä and Leena Myllys. The type specimen was collected by the first author near Toskaljärvi lake (, Enontekiö); there, in a calcareous alpine grassland at an altitude of , the lichen was found growing on dolomite pebbles. It has also been collected from Franklin Bluffs, Alaska, where it was growing on high- pH soil in dwarf shrub tundra. The species epithet ''tibelliorum'' honours "Sanja and Leif Tibell Leif Tibell (born 16 November 1944) is a Swedish lichenologist and Emeritus Professor at the University of Uppsala.

Gunnar Degelius
Gunnar Bror Fritiof Degelius (né Nilsson until 1932; 27 January 1903 – 22 July 1993) 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 (mostly species), 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. Early life and education Born in Uppsala on 27 January 1903, Degelius spent much of his youth in Mariestad. He was introduced to botany at an early age by his father, Bror Nilsson, who was a pharmacist. By the age of six, Gunnar had a size ...

Professor
Professor (commonly abbreviated as Prof.) is an Academy, academic rank at university, universities and other post-secondary education and research institutions in most countries. Literally, ''professor'' derives from Latin as a "person who professes". Professors are usually experts in their field and teachers of the highest rank. In most systems of List of academic ranks, academic ranks, "professor" as an unqualified title refers only to the most senior academic position, sometimes informally known as "full professor". In some countries and institutions, the word "professor" is also used in titles of lower ranks such as associate professor and assistant professor; this is particularly the case in the United States, where the unqualified word is also used colloquially to refer to associate and assistant professors as well. This usage would be considered incorrect among other academic communities. However, the otherwise unqualified title "Professor" designated with a capital let ...

Erik Acharius
Erik Acharius (10 October 1757 – 14 August 1819) 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. Life Acharius was born in 1757 to Johan Eric Acharius and Catharina Margaretha Hagtorn in Gävle.Sernander., K. “Erik Acharius - Svenskt Biografiskt Lexikon.” Fredrik Teodor Borg - Svenskt Biografiskt Lexikon, sok.riksarkivet.se/sbl/Presentation.aspx?id=5503. He received a private education until he was admitted to Gävle Gymnasium in 1770. Later he matriculated at Uppsala University in 1773 where he studied natural history and medicine under Linnaeus and was the last student to defend a dissertation before him.Thell, A., Kärnefelt, I., Seaward, M., & Westberg, M.
