Vezdamyces
''Vezdamyces'' is a small genus of lichen-forming fungi in the family Gomphillaceae. It comprises two species of leaf-dwelling lichens that grow in tropical forests. Taxonomy The genus was established by Amanda Xavier-Leite, Marcela Cáceres, and Robert Lücking, and is named in honour of Antonín Vězda, a prominent 20th-century lichenologist who greatly scientific understanding of leaf-dwelling (foliicolous) lichens, particularly in the family Gomphillaceae. The classification of the two lichens in this genus has been challenging for scientists, and the type species (''V. vulgaris'') has been placed in several different genera over time. It was first described in '' Lopadium'' (1881), then moved to ''Tricharia'', later to '' Actinoplaca'', and then to ''Gyalideopsis'', before finally being recognised as its own distinct genus through modern genetic analysis. Description These lichens form a continuous, finely warty layer on leaf surfaces, but unlike some related gener ...

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 ...

Antonín Vězda
Antonín (Toni) Vězda (25 November 1920 – 10 November 2008) was a Czech lichenologist. After completing a university education that was postponed by World War II, Vězda taught botany at the Czech University of Life Sciences Prague, Czech University of Life Sciences. In 1958, he was dismissed from his university position as a result of the restrictions placed on academic freedoms by the Czechoslovak Socialist Republic, communist regime in power. He eventually was hired as a lichen researcher by the Czechoslovak Academy of Sciences, who allowed him to work from his apartment, which served also as an office and herbarium. Vězda was a productive worker, publishing nearly 400 scientific papers between 1948 and 2008, most solitarily, describing hundreds of new taxon, taxa, and building up a herbarium scientific collection, collection of more than 300,000 specimens. He was praised for his series of exsiccata, exsiccates – sets of dried herbarium specimens – assembled with bot ...

Robert Lücking
Robert Lücking (born 1964) is a German lichenologist, known for his extensive research on foliicolous lichens (lichens that live on leaves) and his significant contributions to the taxonomy, ecology, and biodiversity of fungi and lichens. He earned his master's and PhD from the University of Ulm, focusing on foliicolous lichens. He has received numerous awards for his work, including the Mason E. Hale Award for his doctoral thesis, the Augustin Pyramus de Candolle prize for his monograph, and the Tuckerman Award twice for his publications in the scientific journal '' The Bryologist''. Since 2015, Lücking has been serving as the curator of lichens, fungi, and bryophytes at the Berlin Botanical Garden and Botanical Museum, overseeing a vast scientific collection and contributing to major advancements in molecular phylogenetics in lichenology. Lücking has authored or co-authored the description of more than 1000 taxa, making him one of the most prolific modern lichenologists. ...

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 ...

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 ...

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 ...

Ascospore
In fungi, an ascospore is the sexual spore formed inside an ascus—the sac-like cell that defines the division Ascomycota, the largest and most diverse Division (botany), division of fungi. After two parental cell nucleus, nuclei fuse, the ascus undergoes meiosis (halving of genetic material) followed by a mitosis (cell division), ordinarily producing eight genetically distinct haploid spores; most yeasts stop at four ascospores, whereas some moulds carry out extra post-meiotic divisions to yield dozens. Many asci build turgor, internal pressure and shoot their spores clear of the calm boundary layer, thin layer of still air enveloping the fruit body, whereas subterranean truffles depend on animals for biological dispersal, dispersal. Ontogeny, Development shapes both form and endurance of ascospores. A hook-shaped crozier aligns the paired nuclei; a double-biological membrane, membrane system then parcels each daughter nucleus, and successive wall layers of β-glucan, chitosan ...

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 ...
