Haloplaca
''Haloplaca'' is a genus of lichen-forming fungi in the subfamily Teloschistaceae of the family Teloschistaceae. It contains three species of crustose lichens. The genus was circumscribed by Ulf Arup and colleagues in 2013, with ''Haloplaca britannica'' assigned as the type species. The genus name alludes to the preference of its species for salt-rich environments. All three species occur in the United Kingdom, but ''H. suaedae'' also occurs in Greece, Morocco and Turkey. ''Haloplaca'' species occur near the sea, either on rocks or on plant debris. Description The thallus (the vegetative tissue of lichens) of ''Haloplaca'' is typically crustose; in some species, the margin may extend slightly outward, giving it a more distinct shape. The colour ranges from yellow to pale yellow, and in certain instances, it can appear greyish. Frequently, the surface may be covered in small grain-like structures or soredia, which are reproductive structures in lichens. The , or the outer ...

Haloplaca Sorediella
''Haloplaca sorediella'' is a species of saxicolous (rock-dwelling) crustose lichen in the family Teloschistaceae. It grows exclusively in maritime environments along the western coast of Great Britain. First described in 2006 by the Swedish lichenologist Ulf Arup as ''Caloplaca sorediella'' before being reclassified in 2013, it forms small yellow to orange-yellow patches on coastal rocks, plant debris, and at the base of shoreline plants. The lichen is distinguished by its dot-like soralia that produce fine powdery propagules (soredia) for reproduction, as no fruiting bodies have been observed in this species. It inhabits the upper shoreline zone just above the high tide mark in exposed locations across western England, Wales and Scotland, where it often grows alongside other coastal lichens. Taxonomy It was formally described as a new species in 2006 by the Swedish lichenologist Ulf Arup, who classified it in the genus '' Caloplaca''. The type specimen was collected during a ...

Haloplaca Suaedae
''Haloplaca suaedae'' is a species of epiphytic (plant-dwelling), crustose lichen in the family Teloschistaceae. It grows exclusively as an epiphyte on shrubby sea-blite (''Suaeda vera''). First described in 2001 as ''Caloplaca suaedae'', it was later reclassified in the genus ''Haloplaca''. The lichen is characterised by its extensive grey-green to pale grey thallus composed of small, warty segments, and numerous small orange apothecia (fruiting bodies) with distinctive yellow rims. Found primarily in coastal salt marsh environments and around saline lagoons, it has been documented in England, Greece, Morocco, and Turkey, where it is adaptated to periodic salt water inundation. Taxonomy It was formally described as a new species in 2001 by the lichenologists Oliver L. Gilbert and Brian John Coppins, who initially classified it in the genus '' Caloplaca''. Ulf Arup and colleagues transferred it to the newly created genus ''Haloplaca'' in 2013, as part of a larger molecular ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Teloschistaceae
The Teloschistaceae are a large family (biology), family of mostly lichen-forming fungi belonging to the class (taxonomy), class Lecanoromycetes in the division (botany), division Ascomycota. The family has a cosmopolitan distribution, although its members occur predominantly in temperate climate, temperate regions. Most members are lichens that either saxicolous lichen, live on rock or corticolous lichen, on bark, but about 40 species are lichenicolous fungus, lichenicolousmeaning they are non-lichenised fungi that live on other lichens. Many members of the Teloschistaceae are readily identifiable by their vibrant orange to yellow hue, a result of their frequent anthraquinone content. The presence of these anthraquinone biological pigment, pigments, which confer protection from ultraviolet light, enabled this group to expand from shaded forest habitats to harsher environmental conditions of sunny and arid ecosystems during the Late Cretaceous. Teloschistaceae lichens typically ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soredia
Soredia are common reproduction, reproductive structures of lichens. Lichens asexual reproduction, reproduce asexually by employing simple fragmentation and production of soredia and isidia. Soredia are powdery propagules composed of fungus, fungal hyphae wrapped around cyanobacteria or green algae. These can be either scattered diffusely across the surface of the lichen's thallus, or produced in localized structures called soralia. Fungal hyphae make up the basic body structure of a lichen. The soredia are released through openings in the upper cortex of the lichen structure. After their release, the soredia disperse to establish the lichen in a new location.

Taxa Named By Ulrik Søchting
In biology, a taxon (back-formation from ''taxonomy''; : 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, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). 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 presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lichen Genera
A lichen ( , ) is a hybrid colony (biology), colony of algae or cyanobacteria living symbiotically among hypha, filaments of multiple fungus species, along with yeasts and bacteria embedded in the cortex or "skin", in a mutualism (biology), mutualistic relationship.Introduction to Lichens – An Alliance between Kingdoms . University of California Museum of Paleontology. . Lichens are the lifeform that first brought the term symbiosis (as ''Symbiotismus'') into biological context. Lichens have since been recognized as important actors in nutrient cycling and producers which many higher trophic feeders feed on, such as reindeer, gastropods, nematodes, mites, and springtails. Lichens have properties different from those of their component organisms. They come in man ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Teloschistales Genera
The Teloschistales are an order (taxonomy), order of mostly lichen-forming fungus, fungi belonging to the class (taxonomy), class Lecanoromycetes in the division (mycology), division Ascomycota. According to one 2008 estimate, the order contains 5 Family (biology), families, 66 genera, and 1954 species. The predominant photobiont partners for the Teloschistales are green algae from the genera ''Trebouxia'' and ''Asterochloris''. Molecular phylogenetics The higher-level phylogenetic relationships of the Teloschistales and other members of the two major subclasses of Lecanoromycetes, Lecanoromycetidae and Ostropomycetidae, were clarified in a 2018 publication by Kraichak and colleagues. In the Teloschistales, the family Teloschistaceae has a sister taxon relationship with Megalosporaceae, and the clade containing these two families is itself sister to a clade containing families Brigantiaeaceae and Letrouitiaceae.

Apothecia
An ascocarp, or ascoma (: ascomata), 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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
