Graphidaceae
The Graphidaceae are a family of lichen-forming fungi in the order Graphidales. The family contains nearly a hundred genera and more than 2000 species. Although the family has a cosmopolitan distribution, most Graphidaceae species occur in tropical regions, and typically grow on bark. Taxonomy Graphidaceae was originally proposed by French botanist Barthélemy Charles Joseph Dumortier in 1822 (as "Graphineae"). '' Graphis'', '' Opegrapha'', and '' Arthonia'' were included in the new family. In 2002, the German lichenologist Bettina Staiger revised the Graphidaceae in a monograph, proposing a new classification of genera that was widely accepted until molecular phylogenetic studies led to a further reorganization of the family. Two subfamilies are recognized in the Graphidaceae: *Fissurinoideae *Graphidoideae Subfamily Redonographoideae, proposed by Lücking and colleagues in 2013, has since been promoted to familial status (as the monogeneric family Redonographaceae).

Graphidales
Graphidales is an order (biology), order of lichen-forming fungi in the class Lecanoromycetes. It contains 6 family (biology), families, about 81 genus, genera and about 2,228 species. Family Graphidaceae are the largest crustose family within Graphidales order comprising more than 2000 species, which are widely distributed in tropical and subtropical regions of the world. History The Graphidales were introduced in a 1884 publication by Frigyes Ákos Hazslinszky in Magyar Birodalom Zuzmó-Flórája on page 216 as family Graphideae. In 1907, they were established as an Order (biology), order by American botanist Charles Edwin Bessey, Bessey (1845–1915), When the order was introduced, it contained just two families, the Graphidaceae and Thelotremataceae who were both mainly tropical based and each family had about 800–1000 species. Sherwood in 1977 proposed to maintain a distinction between the Graphidales with mostly lichenised members and the Ostropales which included mostl ...

Fissurina
''Fissurina'' is a genus of lichenized fungi in the family Graphidaceae. It has about 160 species, most of which are found in tropical regions. Taxonomy The genus was circumscription (taxonomy), circumscribed by the French botanist Antoine Laurent Apollinaire Fée in an 1825 publication. Some later authors preferred to use the name ''Fissurina'' to describe infrageneric (i.e., below genus level) groups of the genus ''Graphis (lichen), Graphis'', such as Edvard Vainio in 1921 who used it as a subgenus, and Alexander Zahlbruckner (1923) and Karl Redinger (1935), who used the name for section (botany), sections. ''Fissurina'' is in the family Graphidaceae. In 2018, Kraichak and colleagues, using a "temporal phylogenetic" approach to identify temporal bands for specific taxonomic ranks, proposed placing ''Fissurina'' as the type genus of Fissurinaceae, a family originally proposed by Brendan P. Hodkinson in 2012. This taxonomic proposal was rejected by Robert Lücking in a critical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acanthothecis Abaphoides 150671
''Acanthothecis'' is a genus of lichen-forming fungi in the family Graphidaceae. The genus was circumscribed by Frederick Edward Clements in 1909. These lichens form pale grey-brown to olive-green crusts on tree bark and are characterized by elongated, pencil-like slits containing spores, with distinctive tiny spines on internal filaments that help distinguish them from similar genera. The genus includes about 50 species found primarily in tropical and subtropical forests worldwide, where they grow on living tree bark and serve as indicators of relatively undisturbed woodland environments. Description ''Acanthothecis'' forms a pale grey-brown to olive-green crust (thallus) that may lack a skin () or bear a thin one, and often contains scattered crystals that give a slightly texture. Its fruit bodies are —elongated, pencil-like slits—ranging from immersed to sitting on the surface; their lips are usually well developed and can be smooth or faintly striate. The rim that enc ...

Graphis (lichen)
''Graphis'' is a genus of lichen-forming fungi in the family Graphidaceae. Historically, ''Graphis'' was used as a broad category for species with colourless, transversely septate ascospores within the Graphidaceae. However, with advances in genetic research, this classification has become more refined. As a result, species previously classified under '' Graphina'' have been re-assigned to ''Allographa'' or ''Graphis''. The species complex around '' Graphis scripta'' has also been recognised, leading to the identification of several new species, many of which may have been previously overlooked. Description Genus ''Graphis'' includes crustose lichens, which have a crust-like appearance that can range from being fully embedded in the substrate to sitting on the surface. The lichen's symbiotic partner, or , is green algae from the genus '' Trentepohlia''. The (fruiting bodies) of ''Graphis'' can also be immersed or superficial. These structures are typically elongated, resembli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Graphis Desquamescens
''Graphis desquamescens'' is a species of script lichen in the family Graphidaceae. It has a broad distribution and can be found in various countries including Brazil, Dominica, the United States, Mexico, and Japan. It also occurs in different parts of Australia such as Queensland, New South Wales, Victoria, and Tasmania. It was reported as new to Myanmar in 2020. There has been little agreement in the literature as to the length of the ascospores in this species; they have been given various ranges extending from 18 μm to as high as 50 μm; the ascospores of the lectotype specimen have a reported range of 25–35 μm. The novel pigment named graphisquinone was isolated from cultures of the spore-derived mycobiont A lichen ( , ) is a hybrid colony of algae or cyanobacteria living symbiotically among filaments of multiple fungus species, along with yeasts and bacteria embedded in the cortex or "skin", in a mutualistic relationship.

Redonographaceae
''Redonographa'' is a genus of lichen-forming fungi in the monogeneric family Redonographaceae. It has five species. Taxonomy In 2013, lichenologists Robert Lücking, Anders Tehler, and Helge Thorsten Lumbsch proposed the new family (biology), subfamily Redonographoideae to contain a lineage (evolution), lineage of lichen-forming fungi distinct from the Graphidaceae subfamilies Fissurinoideae and Graphidoideae. They introduced the genus ''Redonographa'' with ''Redonographa chilensis'' assigned its type species. Four species were initially included in the genus; a fifth was added in 2020. The genus is eponym, named in honour of Jorge Redón Figueroa (botany professor at Viña del Mar University and a Emeritus#In academia, professor emeritus at both the University of Chile (Faculty of Sciences) and the University of Valparaíso (Institute of Oceanology) for his significant contributions to Chilean lichenology.

Green Algae
The green algae (: green alga) are a group of chlorophyll-containing autotrophic eukaryotes consisting of the phylum Prasinodermophyta and its unnamed sister group that contains the Chlorophyta and Charophyta/ Streptophyta. The land plants ( Embryophytes) have emerged deep within the charophytes as a sister of the Zygnematophyceae. Since the realization that the Embryophytes emerged within the green algae, some authors are starting to include them. The completed clade that includes both green algae and embryophytes is monophyletic and is referred to as the clade Viridiplantae and as the kingdom Plantae. The green algae include unicellular and colonial flagellates, most with two flagella per cell, as well as various colonial, coccoid (spherical), and filamentous forms, and macroscopic, multicellular seaweeds. There are about 22,000 species of green algae, many of which live most of their lives as single cells, while other species form coenobia (colonies), long filaments ...

Synonym (taxonomy)
In taxonomy, the scientific classification of living organisms, a synonym is an alternative scientific name for the accepted scientific name of a taxon. The Botanical nomenclature, botanical and Zoological nomenclature, zoological codes of nomenclature treat the concept of synonymy differently. * In nomenclature, botanical nomenclature, a synonym is a Binomial nomenclature, scientific name that applies to a taxon that now goes by a different scientific name. For example, Carl Linnaeus, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different Binomial nomenclature, binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyphyly
A polyphyletic group is an assemblage that includes organisms with mixed evolutionary origin but does not include their most recent common ancestor. The term is often applied to groups that share similar features known as homoplasies, which are explained as a result of convergent evolution. The arrangement of the members of a polyphyletic group is called a polyphyly .. ource for pronunciation./ref> It is contrasted with monophyly and paraphyly. For example, the biological characteristic of warm-bloodedness evolved separately in the ancestors of mammals and the ancestors of birds; "warm-blooded animals" is therefore a polyphyletic grouping. Other examples of polyphyletic groups are algae, C4 photosynthetic plants, and edentates. Many taxonomists aim to avoid homoplasies in grouping taxa together, with a goal to identify and eliminate groups that are found to be polyphyletic. This is often the stimulus for major revisions of the classification schemes. Researchers concerned m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
