Pseudocalenia
''Pseudocalenia'' is a fungal genus in the family Gomphillaceae. It comprises the single species ''Pseudocalenia solorinoides'', found in Costa Rica. Taxonomy ''Pseudocalenia'' was circumscribed in 2023 by Amanda Xavier-Leite, Marcela Cáceres, and Robert Lücking to accommodate the species ''Pseudocalenia solorinoides'', which was previously classified in the genus '' Calenia''. Molecular phylogenetics studies demonstrated that ''P. solorinoides'' was not closely related to true ''Calenia'' species, but instead showed closer affinities to the morphologically distinct genera '' Roselviria'' and '' Santricharia''. The genus name alludes to its previous classification in ''Calenia''. While the immersed apothecial structure of ''Pseudocalenia'' bears superficial resemblance to some other species like '' Calenia bullatinoides'' and '' Bullatina aspidota'', molecular evidence indicates these similarities evolved independently multiple times within the Gomphillaceae rather th ...

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 ...

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. ...

Thallus
Thallus (: thalli), from Latinized Greek (), meaning "a green shoot" or "twig", is the vegetative tissue of some organisms in diverse groups such as algae, fungi, some liverworts, lichens, and the Myxogastria. A thallus usually names the entire body of a multicellular non-moving organism in which there is no organization of the tissues into organs. Many of these organisms were previously known as the thallophytes, a polyphyletic group of distantly related organisms. An organism or structure resembling a thallus is called thalloid, thalloidal, thalliform, thalline, or thallose. Even though thalli do not have organized and distinct parts ( leaves, roots, and stems) as do the vascular plants, they may have analogous structures that resemble their vascular "equivalents". The analogous structures have similar function or macroscopic structure, but different microscopic structure; for example, no thallus has vascular tissue. In exceptional cases such as the Lemnoideae, where th ...

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 ...
