Clavascidium Antillarum
''Clavascidium'' is a genus of lichens in the family Verrucariaceae. The genus was circumscription (taxonomy), circumscribed in 1996 by Austrian lichenologist Othmar Breuss. Because the type species of the genus, ''Clavascidium umbrinum'', has been shown using molecular phylogenetics to belong to genus ''Placidium'', Cécile Gueidan and colleagues proposed to unite ''Clavascidium'' with ''Placidium'' in a 2009 publication. Despite this, the genus has been retained in recent publications of fungal classification.

Placidium
''Placidium'' is a genus of crustose lichen, crustose to squamulose lichen, squamulose to almost foliose lichen, foliose lichens. The genus is in the family Verrucariaceae. Most members grow on soil (are terricolous), but some grow on rock (saxicolous). The fruiting bodies are perithecia, flask-like structures immersed in the lichen body (thallus) with only the top opening visible, dotting the thallus. Lichen spot tests are all negative. Members of the genus lack rhizines, but otherwise resemble members of the genus ''Clavascidium''. Members of the genus are commonly called stiplescale lichens or earthscale.Field Guide to California Lichens, Stephen Sharnoff, Yale University Press, 2014, Taxonomy The genus was circumscription (taxonomy), circumscribed in 1855 by Italian lichenologist Abramo Bartolommeo Massalongo.

Eurotiomycetes Genera
Eurotiomycetes is a large class of ascomycetes with cleistothecial ascocarps within the subphylum Pezizomycotina, currently containing around 3810 species according to the Catalogue of Life. It is the third largest lichenized class, with more than 1200 lichen species that are mostly bitunicate in the formation of asci. It contains most of the fungi previously known morphologically as "Plectomycetes". Systematics and phylogeny Internal relationships The class Eurotiomycetes was circumscribed in 1997 by Swedish mycologists Ove Erik Eriksson and Katarina Winka. At that time it only contained the order Eurotiales, which together with the next order added, Onygenales, form a monophyletic group comprising most of the fungi in "Plectomycetes", a group no longer in use that unified fungi under exclusively morphological characteristics. As more orders were added to Eurotiomycetes, the first two along with Arachnomycetales became constrained to the first subclass, Eurotiomycetidae. In 2 ...

Index Fungorum
''Index Fungorum'' is an international project to index all formal names ( scientific names) in the fungus kingdom. the project is based at the Royal Botanic Gardens, Kew, one of three partners along with 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 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 synonyms. ''Index Fungorum'' is one of three nomenclatural repositories recognized by the Nomenclature Committee for Fungi; the others are ''MycoBank'' and ''Fungal Names''.

Catalog Of Life
The Catalogue of Life 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 fro165 peer-reviewed taxonomic databasesthat 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 environment.

International Code Of Nomenclature For Algae, Fungi, And Plants
The ''International Code of Nomenclature for algae, fungi, and plants'' (ICN) is the set of rules and recommendations dealing with the formal botanical names that are given to plants, fungi and a few other groups of organisms, all those "traditionally treated as algae, fungi, or plants".. It was formerly called the ''International Code of Botanical Nomenclature'' (ICBN); the name was changed at the International Botanical Congress in Melbourne in July 2011 as part of the ''Melbourne Code''. which replaced the ''Vienna Code'' of 2005. The current version of the code is the ''Shenzhen Code'' adopted by the International Botanical Congress held in Shenzhen, China, in July 2017. As with previous codes, it took effect as soon as it was ratified by the congress (on 29 July 2017), but the documentation of the code in its final form was not published until 26 June 2018. The name of the ''Code'' is partly capitalized and partly not. The lower-case for "algae, fungi, and plants" indica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Validly Published Name
In botanical nomenclature, a validly published name is a name that meets the requirements in the '' International Code of Nomenclature for algae, fungi, and plants'' for valid publication. Valid publication of a name represents the minimum requirements for a botanical name to exist: terms that appear to be names but have not been validly published are referred to in the ''ICN'' as "designations". A validly published name may not satisfy all the requirements to be '' legitimate''. It is also not necessarily the correct name for a particular taxon and rank. Nevertheless, invalid names (''nomen invalidum'', ''nom. inval.'') are sometimes in use. This may occur when a taxonomist finds and recognises a taxon and thinks of a name, but delays publishing it in an adequate manner. A common reason for this is that a taxonomist intends to write a ''magnum opus'' that provides an overview of the group, rather than a series of small papers. Another reason is that the code of nomenclature chan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Clavascidium Sinense
''Clavascidium sinense'' is a species of squamulose (scaley), ground-dwelling lichen in the family Verrucariaceae. Found in Northwest China, it was formally described as a new species in 2022 by Tingting Zhang and Xinli Wei. The type specimen was collected in Datong City (Yanggao County, Shanxi) at an altitude of . The species epithet ''sinense'' refers to its Chinese distribution. Characteristics of ''Clavascidium sinense'' include the presence of both uniseriate (lined up in a single row) and biseriate (lined up in two rows) ascospores in the asci, pycnidia that are superficial on the surface of the squamules (''laminal''), and mixed-type medulla (with both rounded and elongated cells). The lichen does not react with any of the standard chemical spot tests, and no lichen products were detected using thin-layer chromatography Thin-layer chromatography (TLC) is a chromatography technique used to separate non-volatile mixtures. Thin-layer chromatography is performed on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cécile Gueidan
Cécile Gueidan is a mycologist and lichenologist who applies morphological and molecular biological methods to the origin and taxonomy of fungi that live in lichen symbioses and within rocks. Early life and education Gueidan began working on lichens during her Maitrise (1998) and DEA (1999) qualifications from Université Louis Pasteur and National Museum of Natural History, France. This included practical fieldwork experience with Claude Roux. She then studied molecular methods for lichen taxonomy at Duke University, USA and applied them to pyrenocarpous and Verrucariaceae lichens. Through combining morphological and molecular characters, she was able to refine the taxonomy of these groups. She was awarded her doctorate for this research in 2007. Career Her research focuses on the evolution and taxonomy of lichenised fungi and other ascomycete fungi. After gaining her doctorate, Gueidan carried out research at the Westerdijk Institute in the Netherlands on relationships be ...
