Absconditella Rosea
''Absconditella rosea'' is a species of crustose lichen in the family Stictidaceae. Found in Venezuela, it was formally described as a new species in 2018 by lichenologists Klaus Kalb and André Aptroot. The type specimen was collected at a location between Laguna Mucubají and Pico Mucuñuque ( Mérida) at an altitude of about ; here it was found growing on detritus in páramo. The specific epithet refers to the pale pinkish colour of the ascomata. The lichen is only known to occur in Venezuela. A similar species in genus ''Absconditella'' is '' A. lignicola'', which can be distinguished from ''A. rosea'' by its whitish apothecia and differences in 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 s ... morphology.

Klaus Kalb
Klaus Kalb (born 1942) is a German lichenologist and an authority on tropical lichens. Biography Klaus Kalb was born in Nuremberg in 1942 and grew up in southern Bavaria. From 1960 to 1965 he studied biology, chemistry, and geography at the University of Erlangen–Nuremberg. Kalb was greatly interested in lichens and decided to pursue a doctoral degree; his thesis work was about lichen communities in the Ötztal Alps. From 1978–1981 he was a teacher at the Colégio Visconde de Porto Seguro in São Paulo, Brazil. This position afforded him the opportunity to initiate research into tropical lichens. Kalb earned his habilitation from the University of Regensburg in 1989, becoming an associate professor with that institution. In 2014, the University of Wisconsin herbarium purchased Kalb's lichen collection of 60,000 specimens for $75,000. With the acquisition of Kalb's collection, rich in tropical and European specimens, the herbarium houses about 70% of the world's know ...

Ascomata
An ascocarp, or ascoma (), is the fruiting body ( sporocarp) of an ascomycete phylum fungus. It consists of very tightly interwoven hyphae and millions of embedded asci, each of which typically contains four to eight ascospores. Ascocarps are most commonly bowl-shaped (apothecia) but may take on a spherical or flask-like form that has a pore opening to release spores (perithecia) or no opening (cleistothecia). Classification The ascocarp is classified according to its placement (in ways not fundamental to the basic taxonomy). It is called ''epigeous'' if it grows above ground, as with the morels, while underground ascocarps, such as truffles, are termed ''hypogeous''. The structure enclosing the hymenium is divided into the types described below (apothecium, cleistothecium, etc.) and this character ''is'' important for the taxonomic classification of the fungus. Apothecia can be relatively large and fleshy, whereas the others are microscopic—about the size of flecks of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

Absconditella Lignicola
''Absconditella'' is a genus of lichenised fungi in the family Stictidaceae. The genus was circumscribed in 1965 by Czech lichenologist Antonín Vězda, with ''Absconditella sphagnorum'' assigned as the type species. ''Absconditella'' is characterised by gyalectoid apothecia with a hymenium that is not amyloid, without a dark pigment and thalli containing green algae as photobionts. The genus name means "hidden", a reference to the scant structure of the thallus and its small apothecia. Species * ''Absconditella amabilis'' – Canada * '' Absconditella annexa'' * ''Absconditella antarctica'' – Antarctica * '' Absconditella baegasanensis'' * '' Absconditella celata'' – Lappland * '' Absconditella delutula'' * '' Absconditella duplicella'' * '' Absconditella fossarum'' * '' Absconditella lignicola'' * ''Absconditella pauxilla'' * '' Absconditella rosea'' – South America * ''Absconditella rubra'' – Europe * ''Absconditella sphagnorum'' * ''Absconditella term ...

Botanical Name
A botanical name is a formal scientific name conforming to the '' International Code of Nomenclature for algae, fungi, and plants'' (ICN) and, if it concerns a plant cultigen, the additional cultivar or Group epithets must conform to the ''International Code of Nomenclature for Cultivated Plants'' (ICNCP). The code of nomenclature covers "all organisms traditionally treated as algae, fungi, or plants, whether fossil or non-fossil, including blue-green algae ( Cyanobacteria), chytrids, oomycetes, slime moulds and photosynthetic protists with their taxonomically related non-photosynthetic groups (but excluding Microsporidia)." The purpose of a formal name is to have a single name that is accepted and used worldwide for a particular plant or plant group. For example, the botanical name ''Bellis perennis'' denotes a plant species which is native to most of the countries of Europe and the Middle East, where it has accumulated various names in many languages. Later, the plant was intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
