Henssenia
''Henssenia'' is a genus of lichen-forming fungi in the family Koerberiaceae. It has four species. The genus was circumscribed in 2017 by Damien Ertz, Roar Skovlund Poulsen, and Ulrik Søchting, with '' Henssenia glaucella'' assigned as the type species. The main distinguishing characteristic of the genus is simple ascospores (i.e., lacking septa) that sometimes have a plasma bridge. The genus name honours German lichenologist Aino Henssen Aino Marjatta Henssen (12 April 1925, Elberfeld – 29 August 2011, Marburg), was a German lichenologist and systematist.

Koerberiaceae
Koerberiaceae is a small family of lichen-forming fungi in the order Peltigerales. It contains 3 genera and 9 species. The family was proposed by Toby Spribille and Lucia Muggia in 2012, after molecular phylogenetic analysis revealed the existence of three lineages of lichen-forming fungi in the suborder Peltigerineae of the order Peltigerales. The lineages represented the genera ''Steinera'', ''Koerberia'' (the type genus of the family), and ''Vestergrenopsis''. The latter genus was later folded into synonymy with ''Tingiopsidium''. '' Steinera'', circumscribed by Alexander Zahlbruckner in 1906, was previously classified in family Koerberiaceae, but the genus and many of its species were transferred to the family Arctomiaceae in 2017, and a new genus ''Henssenia'' was created to contain the remaining species. Description Members of the Koerberiaceae have thalli that are squamulose (scaley) to placodioid, and have deep grooves on the upper surface that radiate outward from the ...

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 ...

Taxa Described In 2017
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peltigerales
Peltigerales is an order of lichen-forming fungi belonging to the class Lecanoromycetes in the division Ascomycota. The taxonomy of the group has seen numerous changes; it was formerly often treated as a suborder of the order Lecanorales. It contains two suborders, eight families and about 45 genera such as ''Lobaria'' and ''Peltigera''. The fungi form lichens in a symbiotic relationship with one or two photosynthetic partners which may be a cyanobacterium such as ''Nostoc'' or a green alga such as '' Coccomyxa''. The majority of species contain just a cyanobacterium, a smaller number have both a cyanobacterium and a green alga while only a few species have just a green alga. The thallus of the lichen may be foliose (leafy), subfruticose (somewhat shrubby) or granular-squamulose (scaly). The thallus attaches to a surface by means of small root-like rhizines. In some species, the thallus may vary in appearance depending on whether it contains a cyanobacterium or a green alga. Some ...

Aino Henssen
Aino Marjatta Henssen (12 April 1925, Elberfeld – 29 August 2011, Marburg), was a German lichenologist and systematist. Her father, Gottfried Henssen, was a folklorist and her mother was Finns, Finnish. Education and career Henssen began her studies in Biology in Freiburg, Germany, before continuing in Marburg, Germany. She obtained her doctorate in 1953, which focused on the physiology of ''Spirodela polyrhiza''. In 1963, she became the curator of the ''Botanisches Institut'' at ''University of Marburg, Philipps-Universität'' in Marburg, Germany. Following her habilitation in 1965, she was appointed in 1970 to the position of Associate Professor for thallophyte studies. She retired in 1990. "Short biographies of 104 lichenologists who have played a key role in the development of German lichenology are provided." ("Aino Henssen" on pp. 41–43) Contributions Henssen made many advancements to the taxonomic knowledge of cyanolichens and wrote a textbook on the subject. This book r ...

Septum
In biology, a septum (Latin for ''something that encloses''; plural septa) is a wall, dividing a cavity or structure into smaller ones. A cavity or structure divided in this way may be referred to as septate. Examples Human anatomy * Interatrial septum, the wall of tissue that is a sectional part of the left and right atria of the heart * Interventricular septum, the wall separating the left and right ventricles of the heart * Lingual septum, a vertical layer of fibrous tissue that separates the halves of the tongue. *Nasal septum: the cartilage wall separating the nostrils of the nose * Alveolar septum: the thin wall which separates the alveoli from each other in the lungs * Orbital septum, a palpebral ligament in the upper and lower eyelids * Septum pellucidum or septum lucidum, a thin structure separating two fluid pockets in the brain * Uterine septum, a malformation of the uterus * Vaginal septum, a lateral or transverse partition inside the vagina * Intermuscular sep ...

Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.
