Microcalicium
''Microcalicium'' is a genus of lichen-forming fungi in the order Pertusariales. It is the only genus in the monotypic family (biology), family Microcaliciaceae. These taxa were circumscription (taxonomy), circumscribed by the Finnish lichenologist Edvard August Vainio in 1927, with ''Microcalicium disseminatum'' assigned as the type species. Description Species of ''Microcalicium'' have a mazaediate ascomata (an irregularly spherical fruiting body in which ascus walls break down to leave a dry, loose, amorphous, powdery, often dark, mass of ascospore, spores together with disintegrating ascus, asci and paraphyses). Their asci are ellipsoid in shape and non-amyloid (mycology), amyloid. Species , Species Fungorum accepts the following five species in the genus ''Microcalicium'': *''Microcalicium ahlneri'' *''Microcalicium arenarium'' *''Microcalicium conversum'' *''Microcalicium disseminatum'' *''Microcalicium loraasii'' References {{Taxonbar, from1=Q6839301, from2=Q1 ...

Pertusariales
The Pertusariales are an order (biology), order of fungi in the class Lecanoromycetes, comprising 8 family (biology), families, 31 genera, and over 600 species, many of which form lichens. This diverse group is characterized by complex taxonomy (biology), taxonomic history and ongoing phylogenetic revisions. Originally proposed by Maurice Choisy in 1949 and later formally published by the lichenologists David L. Hawksworth and Ove Eriksson in 1986, Pertusariales has undergone significant reclassification due to molecular phylogenetics studies. The order includes well-known genera such as ''Pertusaria'' and ''Ochrolechia'', as well as families like Megasporaceae and Icmadophilaceae. Pertusariales species exhibit a wide range of morphology (biology), morphological features and ecological roles, from non-lichenized fungi to various forms of lichen symbioses. The order's taxonomy has been subject to considerable debate and revision, with recent research leading to the establishment o ...

Leif Tibell
Leif Tibell (born 16 November 1944) is a Swedish lichenologist and Emeritus Professor at the University of Uppsala. He is known for his expertise on calicioid lichens. He was awarded the Acharius Medal in 2012 for lifetime achievements in lichenology. Biography Tibell was born in Gothenburg, Sweden, in 1944. He developed an interest in lichens at a young age after meeting the prominent lichenologist Gunnar Degelius through the Gothenburg Botanical Garden, where they were both members. Degelius mentored Tibell, and recommended to him that he should study the subject at Uppsala University, which he did after moving there in the mid 1960s. He continued with graduate studies under the supervision of Rolf Santesson after accompanying him on a research excursion to Norway's Varanger Peninsula in 1966. Santesson was Curator of the Herbarium at the Botany Department. He was also the father of Johan Santesson, who knew Tibell through an organic chemistry research group they were both p ...

Paraphyses
Paraphyses are erect sterile filament-like support structures occurring among the reproductive apparatuses of fungi, ferns, bryophytes and some thallophytes. The singular form of the word is paraphysis. In certain fungi, they are part of the fertile spore-bearing layer. More specifically, paraphyses are sterile filamentous hyphal end cells composing part of the hymenium of Ascomycota and Basidiomycota interspersed among either the asci or basidia respectively, and not sufficiently differentiated to be called cystidia A cystidium (: cystidia) is a relatively large cell found on the sporocarp of a basidiomycete (for example, on the surface of a mushroom gill), often between clusters of basidia. Since cystidia have highly varied and distinct shapes that are o ..., which are specialized, swollen, often protruding cells. The tips of paraphyses may contain the pigments which colour the hymenium. In ferns and mosses, they are filament-like structures that are found on sporangi ...

Taxa Named By Edvard August Vainio
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] |
Catalog 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 environ ...

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 ...
