Batistomyces
''Batistomyces'' is a small genus of fungi in the family Gomphillaceae. It has two species of leaf-dwelling (foliicolous) lichens. These microlichens form very thin layers on the surface of leaves, appearing to the naked eye as small, fuzzy dark patches due to their numerous short black bristles. Taxonomy The genus was established by Amanda Xavier-Leite, Marcela Cáceres, and Robert Lücking in 2023. It is named in honour of Augusto Chaves Batista, a Brazilian mycologist known for his research on tropical fungi and lichens, particularly those in the family Gomphillaceae. The genus was created after molecular studies showed that these species were distinct from ''Tricharia'', where they were previously classified. While they share some features with ''Tricharia'' species, ''Batistomyces'' can be distinguished by its uniquely dense arrangement of short, stiff black bristles on its surface. Description These lichens form a continuous layer (thallus) on leaf surfaces, with a disti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gomphillaceae
The Gomphillaceae are a family of lichen-forming fungi in the order Graphidales. Species in this family are found mostly in tropical regions. The family underwent a major molecular phylogenetics-led reorganisation in 2023, in which 17 genera were recognised and formally established as new or reinstated. Taxonomy The Gomphillaceae has undergone significant taxonomic revision as molecular analysis techniques have improved scientists' understanding of relationships between species. As of 2024, the family includes approximately 440 accepted species, of which 422 are lichenised (form a symbiotic relationship with algae) and 18 are lichenicolous or fungicolous (grow on other lichens or fungi). The family is particularly diverse in tropical regions, where many species grow on leaves in wet forests. However, some members, particularly in the genus '' Gyalideopsis'', can also be found growing on other surfaces and extend into temperate regions. Recent molecular phylogenetics studies (an ...

Tricharia
''Tricharia'' is a genus of lichens in the family Gomphillaceae. It has an estimated 30 species. Taxonomy Recent molecular studies have shown that the long, carbon-black bristles (sterile ) that once united many species under ''Tricharia'' evolved several times independently within the family. A two-gene phylogeny published in 2024 confirmed that the type lineage of ''Tricharia'' (species with pale, thin-walled apothecial rims) forms a well-supported clade distinct from three other "black-setae" groups that had been bundled together on the basis of bristle morphology. In particular, the Costa Rican species ''Tricharia paradoxa''—long treated as an odd member of the genus—was transferred to the monospecific genus '' Paratricharia'' and shown to be sister to '' Caleniopsis'' in the early-diverging ''Aulaxina'' clade, far removed from ''Tricharia'' in the strict sense. The same analysis placed the remaining black-setae taxa in the separate genera '' Microxyphiomyces'' and ''San ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxa Described In 2023
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] |
Graphidales Genera
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 ...

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] |
Foliicolous Lichen
A foliicolous lichen is a lichen which grows on the surfaces of living leaves of vascular plants, usually inhabiting the upper surface (''epiphyllous'') but sometimes also the lower surface (''hypophyllous''). Foliicolous lichens largely occur in tropical environments and of the over 800 foliicolous lichens accepted (as of 2008) over 600 of these are known from the tropics. Unlike most lichens which are common in humid but cool and temperate climates, these tropical lichens are more suited to the higher temperatures and lower light levels present beneath the rainforest Canopy (biology), canopy, where they are involved in the nutrient cycle and water cycle, water retention. Chlorophyta are common photosynthetic partner phycobionts of epiphyllous lichens.Lichen Photobionts, University of Nebraska Oma ...

Molecular Phylogenetics
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetics, phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in Taxonomy (biology), taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tre ...
