Lecidella Aptrootii
''Lecidella'' is a genus of crustose lichens in the family Lecanoraceae. Taxonomy ''Lecidella'' was circumscribed by German lichenologist Gustav Wilhelm Körber in 1855. It was not widely used until more than a century later, when Hannes Hertel recognized it first as a subgenus of ''Lecidea'', and then a couple of year after as a distinct genus. A phylogenetic analysis of the genus using 11 species (mostly from China) found that ''Lecidella'' species fall into three major clades, which were proposed as three informal groups: ''Lecidella stigmatea'' group, ''L. elaeochroma'' group and'' L. enteroleucella'' group. Description ''Lecidella'' species have a thallus that is crustose, and , meaning that it resembles the genus '' Biatora''–having a proper exciple, which is not coal-black (, but coloured or blackening. It has eight-spored asci of the ''Lecidella'' type. The ascospores are and hyaline, while the conidia are curved and threadlike. Morphologically simil ...

Ascus
An ascus (; : asci) is the sexual spore-bearing cell produced in ascomycete fungi. Each ascus usually contains eight ascospores (or octad), produced by meiosis followed, in most species, by a mitotic cell division. However, asci in some genera or species can occur in numbers of one (e.g. '' Monosporascus cannonballus''), two, four, or multiples of four. In a few cases, the ascospores can bud off conidia that may fill the asci (e.g. '' Tympanis'') with hundreds of conidia, or the ascospores may fragment, e.g. some '' Cordyceps'', also filling the asci with smaller cells. Ascospores are nonmotile, usually single celled, but not infrequently may be coenocytic (lacking a septum), and in some cases coenocytic in multiple planes. Mitotic divisions within the developing spores populate each resulting cell in septate ascospores with nuclei. The term ocular chamber, or oculus, refers to the epiplasm (the portion of cytoplasm not used in ascospore formation) that is surrounded by the ...

Catalogue Of Life
The Catalogue of Life (CoL) is an online database that provides an index of known species of animals, plants, fungi, and microorganisms. It was created in 2001 as a partnership between the global Species 2000 and the American Integrated Taxonomic Information System. The Catalogue is used by research scientists, citizen scientists, educators, and policy makers. The Catalogue is also used by the Biodiversity Heritage Library, the Barcode of Life Data System, '' Encyclopedia of Life'', and the Global Biodiversity Information Facility. The Catalogue currently compiles data from 165 peer-reviewed taxonomic databases that are maintained by specialist institutions around the world. the COL Checklist lists 2,067,951 of the world's 2.2m extant species known to taxonomists on the planet at present time. Structure The Catalogue of Life employs a simple data structure to provide information on synonymy, grouping within a taxonomic hierarchy, common names, distribution and ecological e ...

Species Fungorum
''Index Fungorum'' is an international project to index all formal names (Binomial nomenclature, scientific names) in the fungus Kingdom (biology), kingdom. As of 2015, the project is based at the Royal Botanic Gardens, Kew, one of three partners along with Landcare Research New Zealand Limited, Landcare Research and the Institute of Microbiology, Chinese Academy of Sciences. It is somewhat comparable to the International Plant Names Index (IPNI), in which the Royal Botanic Gardens is also involved. A difference is that where IPNI does not indicate Correct name (botany), correct names, the ''Index Fungorum'' does indicate the status of a name. In the returns from the search page, a currently correct name is indicated in green, while others are in blue (a few, aberrant usages of names are indicated in red). All names are linked to pages giving the correct name, with lists of Synonym (taxonomy), synonyms. ''Index Fungorum'' is one of three nomenclatural repositories recognized b ...

Tasmidella
''Tasmidella'' is a lichen genus in the family Ramalinaceae. Circumscribed by Gintaras Kantvilas, Josef Hafellner, and John A. Elix in 1999, it contains the single species ''Tasmidella variabilis'', found in Tasmania. It is distinguished from the closely related genus '' Megalaria'' by having simple spores In biology, a spore is a unit of sexual (in fungi) or asexual reproduction that may be adapted for dispersal and for survival, often for extended periods of time, in unfavourable conditions. Spores form part of the life cycles of many plant ... with a layered wall.

Japewiella
''Japewiella'' is a genus of lichen in the family Lecanoraceae. It was circumscribed in 2000 by German botanist and lichenologist Christian Printzen as a segregate of the genus '' Japewia''. The genus name of ''Japewia'' was in honour of Peter Wilfrid James (1930 - 2014), who was an English botanist (Mycology and Lichenology). The genus was circumscribed by Christian Printzen in Bryologist vol.102 on page 715 in 1999. The type, '' Japewiella carrollii'', is an oceanic species that occurs in maritime regions of Europe and Macaronesia. Description ''Japewiella'' species are crust lichens that grow on bark. They are characterized by their biatorine apothecia, thick-walled, simple ascospores, eight-spored asci with a conspicuous ''masse axiale'' (similar to asci found in members of genus ''Lecidella''). They have a well-developed excipulum (a saucer-shaped rim around the hymenium) comprising branched and anastomosing, gelatinized hyphae. Species *'' Japewiella carrollii'' (Copp ...

Morphology (biology)
Morphology (from Ancient Greek μορφή (morphḗ) "form", and λόγος (lógos) "word, study, research") is the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance (shape, structure, color, pattern, size), as well as the form and structure of internal parts like bones and organs, i.e., anatomy. This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of the overall structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Fried ...
