Fulvophyton Rostratum
''Fulvophyton'' is a genus of lichen-forming fungi in the family Roccellographaceae. It has 11 species. ''Fulvophyton'' is characterised by its crust-like thallus, which is often pale yellowish-brown in colour. This genus features a from the green algal genus '' Trentepohlia'' and exhibits a unique arrangement of reproductive structures. Taxonomy The genus was circumscribed in 2011 by lichenologists Damien Ertz and Anders Tehler, as part of a molecular phylogenetic-based restructuring of the order Arthoniales. The genus encompasses species that were previously classified in the genus '' Sclerophyton'', as proposed by Laurens Sparrius in 2004. However, these species deviate from the type of that genus due to the presence of rounded to ellipsoid ascomata, which are often covered in white , and a hyaline or pale . The type species of ''Fulvophyton'' is '' F. stalactinum'', a lichen first described by William Nylander in 1855 (as ''Chiodecton stalactinum''). Description Th ...

William Nylander (botanist)
William (Wilhem) Nylander (3 January 1822 – 29 March 1899) was a Finnish botanist and entomologist. Nylander was born in Oulu, and taught at the University of Helsinki before moving to Paris, France, where he lived until his death in 1899. Nylander studied medicine, receiving a degree in 1847. Nylander pioneered the technique of determining the taxonomy of lichens by the use of chemical reagents, such as potassium hydroxide, tinctures of iodine and calcium hypochlorite, still used by lichenologists as the K and C tests. Nylander was the first to realise the effect of atmospheric pollution on the growth of lichens, an important discovery that paved the way for the use of lichens to detect pollution and determine the cleanness of air. His brother Fredrik Nylander was also a botanist. Nylander was one of the most prolific authors of new fungal and lichen species, having formally described about 3700 in his career. He edited the exsiccata Exsiccata (Latin, ''gen.'' -ae, ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fulvophyton Macrosporum
''Fulvophyton macrosporum'' is a species of corticolous (bark-dwelling), crustose lichen in the family Roccellographaceae. Found in the Seychelles, it was formally described as a new species in 2017 by lichenologists Damien Ertz and Paul Diederich. Its differentiation from the morphologically similar '' Sclerophyton madagascariense'' primarily hinges on its 10–14 (and at times, up to 16) septate (partitioned) ascospores and the existence of psoromic acid, while ''S. madagascariense'' typically contains 8–10-septate ascospores and features stictic acid. ''Fulvophyton macrosporum'' was first identified in Seychelles, in the Praslin National Park, situated southeast of Vallée de Mai. The species was discovered growing on trees between altitudes of . Its species epithet ''macrosporum'' alludes to the relatively large that characterise the species. The thallus of ''Fulvophyton macrosporum'' can measure up to approximately in diameter and has a continuous, smooth, yellow ...

Catalogue Of Life
The Catalogue of Life (CoL) is an online database that provides an index of known species of animals, plants, fungi, and microorganisms. It was created in 2001 as a partnership between the global Species 2000 and the American Integrated Taxonomic Information System. The Catalogue is used by research scientists, citizen scientists, educators, and policy makers. The Catalogue is also used by the Biodiversity Heritage Library, the Barcode of Life Data System, '' Encyclopedia of Life'', and the Global Biodiversity Information Facility. The Catalogue currently compiles data from 165 peer-reviewed taxonomic databases that are maintained by specialist institutions around the world. the COL Checklist lists 2,067,951 of the world's 2.2m extant species known to taxonomists on the planet at present time. Structure The Catalogue of Life employs a simple data structure to provide information on synonymy, grouping within a taxonomic hierarchy, common names, distribution and ecological e ...

Species Fungorum
''Index Fungorum'' is an international project to index all formal names (Binomial nomenclature, scientific names) in the fungus Kingdom (biology), kingdom. As of 2015, the project is based at the Royal Botanic Gardens, Kew, one of three partners along with Landcare Research New Zealand Limited, Landcare Research and the Institute of Microbiology, Chinese Academy of Sciences. It is somewhat comparable to the International Plant Names Index (IPNI), in which the Royal Botanic Gardens is also involved. A difference is that where IPNI does not indicate Correct name (botany), correct names, the ''Index Fungorum'' does indicate the status of a name. In the returns from the search page, a currently correct name is indicated in green, while others are in blue (a few, aberrant usages of names are indicated in red). All names are linked to pages giving the correct name, with lists of Synonym (taxonomy), synonyms. ''Index Fungorum'' is one of three nomenclatural repositories recognized b ...

Fusiform
Fusiform (from Latin ''fusus'' ‘spindle’) means having a spindle (textiles), spindle-like shape that is wide in the middle and tapers at both ends. It is similar to the lemon (geometry), lemon-shape, but often implies a focal broadening of a structure that continues from one or both ends, such as an aneurysm on a blood vessel. Examples * Fusiform, a body shape common to many aquatic animals, characterized by being tapered at both the head and the tail * Fusiform, a classification of aneurysm * Fusiform bacteria (spindled rods, that is, fusiform bacilli), such as the Fusobacteriota * Fusiform cell (biology) * Fusiform face area, a part of the human visual system which seems to specialize in facial recognition * Fusiform gyrus, part of the temporal lobe of the brain * Fusiform muscle, where the fibres run parallel along the length of the muscle * Fusiform neuron, a spindle-shaped neuron References {{Reflist Geometric shapes See also * Streamliner, a fusiform hydro- ...

Ascus
An ascus (; : asci) 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 ...

Anastomosis
An anastomosis (, : anastomoses) is a connection or opening between two things (especially cavities or passages) that are normally diverging or branching, such as between blood vessels, leaf veins, or streams. Such a connection may be normal (such as the foramen ovale in a fetus' heart) or abnormal (such as the patent foramen ovale in an adult's heart); it may be acquired (such as an arteriovenous fistula) or innate (such as the arteriovenous shunt of a metarteriole); and it may be natural (such as the aforementioned examples) or artificial (such as a surgical anastomosis). The reestablishment of an anastomosis that had become blocked is called a reanastomosis. Anastomoses that are abnormal, whether congenital or acquired, are often called fistulas. The term is used in medicine, biology, mycology, geology, and geography. Etymology Anastomosis: medical or Modern Latin, from Greek ἀναστόμωσις, anastomosis, "outlet, opening", Greek ana- "up, on, upon", stoma "mouth" ...
