Huneckia
''Huneckia'' is a genus of crustose lichens in the subfamily Caloplacoideae of the family Teloschistaceae. It has four species. Taxonomy The genus was circumscription (taxonomy), circumscribed in 2014 by Sergei Kondratyuk, John Alan Elix, Jack Elix, Ingvar Kärnefelt, Arne Thell, and Jae-Seoun Hur, as a segregate of the genus ''Caloplaca''.

Siegfried Huneck
Siegfried Huneck (9 September 1928 – 9 October 2011) was a German chemist and lichenologist. Much of his scientific career was hampered by the political situation in the former German Democratic Republic. He rejected pursuing a career in academia, and instead ended up working at the Leibniz Institute of Plant Biochemistry, a public research institute, from 1969 until his retirement in 1993. Despite his relative isolation and restricted freedoms in East Germany, Huneck had numerous professional contacts both in Germany and abroad, and was a highly published scholar. Many of his more than 400 scientific publications dealt with the chemistry of lichen products. He was awarded the Acharius Medal for lifetime achievements in lichenology in 1996. Life and career Siegfried Huneck was born on 9 September 1928 in , a small settlement in the Thuringian Forest region (Thuringia, Germany). He attended primary school there, and then grammar school for boys in Schmalkalden, which he compl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Teloschistaceae
The Teloschistaceae are a large family of mostly lichen-forming fungi belonging to the class Lecanoromycetes in the division Ascomycota. The family, estimated to contain over 1800 species, was extensively revised in 2013, including the creation or resurrection of 31 genera. It contains three subfamilies: Xanthorioideae, Caloplacoideae, and Teloschistoideae. A fourth subfamily, Brownlielloideae, proposed in 2015, has been shown to be part of the Teloschistoideae. Genera This is a list of the genera contained within the Teloschistaceae, based on a 2020 review and summary of ascomycete classification. Following the genus name is the taxonomic authority, year of publication, and the number of species: *'' Amundsenia'' – 2 spp. *'' Andina'' - 1 sp. *'' Apatoplaca'' – 1 sp. *'' Aridoplaca'' - 1 sp. *'' Athallia'' – 17 spp. *'' Austroplaca'' – 10 spp. *'' Blastenia'' – 11 spp. *'' Brownliella'' – 4 spp. *'' Bryoplaca'' – 3 spp. *'' Calogaya'' – 19 spp. *'' Calop ...

John Alan Elix
John Alan (Jack) Elix (born 1941) 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. Education His first degree, B.Sc., and his Ph.D were both in organic chemistry from the University of Adelaide. This was followed by post-doctoral years at the University of Cambridge and then a D.Sc. in natural products chemistry from the Australian National University. Career Elix spent a post doctoral year in 1966 at Cambridge, returning to Australia in 1967 to a lectureship in chemistry at the ANU. He retired as professor of chemistry in 2002, becoming professor emeritus. By 1975 he had already published several papers on the organic chemistry of lichens, and ultimately leading to work on the evolution, taxonomy and phylogeny of liche ...

Morphology (biology)
Morphology is a branch of biology dealing with the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance (shape, structure, colour, pattern, size), i.e. external morphology (or eidonomy), as well as the form and structure of the internal parts like bones and organs, i.e. internal morphology (or anatomy). This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of gross structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Friedrich Burdach ...

Ascospore
An ascus (; ) is the sexual spore-bearing cell produced in ascomycete fungi. Each ascus usually contains eight ascospores (or octad), produced by meiosis followed, in most species, by a mitotic cell division. However, asci in some genera or species can occur in numbers of one (e.g. ''Monosporascus cannonballus''), two, four, or multiples of four. In a few cases, the ascospores can bud off conidia that may fill the asci (e.g. ''Tympanis'') with hundreds of conidia, or the ascospores may fragment, e.g. some ''Cordyceps'', also filling the asci with smaller cells. Ascospores are nonmotile, usually single celled, but not infrequently may be coenocytic (lacking a septum), and in some cases coenocytic in multiple planes. Mitotic divisions within the developing spores populate each resulting cell in septate ascospores with nuclei. The term ocular chamber, or oculus, refers to the epiplasm (the portion of cytoplasm not used in ascospore formation) that is surrounded by the "bourrelet ...
