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, Eurotiomyceti ...

Verrucaria Nigrescens
''Verrucaria nigrescens'' is a widespread species of crustose lichen in the family Verrucariaceae. First described by Christiaan Hendrik Persoon in 1795, it has maintained its original name despite accumulating many synonym (taxonomy), synonyms over its complex taxonomic history. The species is characterised by its dark-brown, (cracked into small polygonal segments) thallus, and commonly colonisation (biology), colonises stone surfaces, especially limestone. Due to its dark pigmentation, ''V. nigrescens'' significantly absorbs sunlight, elevating temperatures on the rock surfaces it inhabits. This contributes to stone deterioration, posing challenges for conservation of historical monuments and buildings, and has prompted research into specialised control methods such as laser cleaning. Taxonomy It was first species description, formally described as a new species by Christiaan Hendrik Persoon in 1795. Despite a long and varied taxonomic history during which numerous syn ...

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 ...

Verrucariales
Verrucariales is an order (biology), order of Ascomycota, ascomycetous fungi within the subclass Chaetothyriomycetidae of the class Eurotiomycetes. Although most of the Verrucariales are lichenised, the family Sarcopyreniaceae consists of 11 species of lichenicolous fungi, lichenicolous (lichen-dwelling) fungi. Phylogenomics, Phylogenomic analysis suggests that the divergent evolution, divergence between the lichenised Verrucariales and nonlichenised Chaetothyriales occurred about 131 million years ago. Description Members of the Verrucariales are primarily organisms that form symbiotic relationships with algae or cyanobacteria, creating lichens. These lichens are remarkable for their ability to thrive in a wide range of environments, from extremely dry land habitats to freshwater and even marine ecosystems, where they are particularly abundant. A significant portion of Verrucariales species can be found saxicolous lichen, growing on rocks, especially in temperate climates. Some ...

Arachnomycetales
''Arachnomyces'' is a genus of cleistothecial ascomycete fungi described in 1902, of which the anamorph (asexual) stage is the genus ''Onychocola''. Although morphologically similar to members of other families, the fungus now belongs to its own monotypic family Arachnomycetaceae, which is the only family in the monotypic order Arachnomycetales. Phylogeny The placement of ''Arachnomyces'' has changed multiple times due to its morphological similarities to members of different families. When first described in 1902, it was included in the old family Perisporiaceae. Later it was considered as part of Onygenaceae, then it was placed within the Gymnoascaceae in 1996. Thanks to phylogenetic analyses ''Arachnomyces'' is currently recognized as a distinct monophyletic lineage, composing its own family Arachnomycetaceae and order Arachnomycetales within the class Eurotiomycetes. Taxonomy There are currently 16 accepted species of ''Arachnomyces''. * '' Arachnomyces bostrychodes'' * '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Monophyletic
In biological cladistics for the classification of organisms, monophyly is the condition of a taxonomic grouping being a clade – that is, a grouping of organisms which meets these criteria: # the grouping contains its own most recent common ancestor (or more precisely an ancestral population), i.e. excludes non-descendants of that common ancestor # the grouping contains all the descendants of that common ancestor, without exception Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic'' grouping meets 1. but not 2., thus consisting of the descendants of a common ancestor, excepting one or more monophyletic subgroups. A '' polyphyletic'' grouping meets neither criterion, and instead serves to characterize convergent relationships of biological features rather than genetic relationships – for example, night-active primates, fruit trees, or aquatic insects. As such, these characteristic features of a polyphyletic grouping ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Onygenales
The Onygenales are an order of fungi in the class Eurotiomycetes and division Ascomycota. The order's last common ancestor is estimated to have lived 150 million years ago. Onygenales can consume and break down keratin, the main component of the outer layer of skin. They are primarily found on animals, droppings, and areas frequented by animals. Many are dimorphic, and can change from mold to yeast form depending on their environment. Many onygenalean fungi are pathogen In biology, a pathogen (, "suffering", "passion" and , "producer of"), in the oldest and broadest sense, is any organism or agent that can produce disease. A pathogen may also be referred to as an infectious agent, or simply a Germ theory of d ...s. One species, '' Trichophyton rubrum'', is the primary cause of athlete's foot. This order also includes the '' Coccidioides'' implicated in Valley fever. The Onygenales are important as emerging human pathogens because of the rising rates of immunosuppress ...

Mycologist
Mycology is the branch of biology concerned with the study of fungi, including their taxonomy, genetics, biochemical properties, and use by humans. Fungi can be a source of tinder, food, traditional medicine, as well as entheogens, poison, and infection. Yeasts are among the most heavily utilized members of the fungus kingdom, particularly in food manufacturing. Mycology branches into the field of phytopathology, the study of plant diseases. The two disciplines are closely related, because the vast majority of plant pathogens are fungi. A biologist specializing in mycology is called a mycologist. Overview The word ''mycology'' comes from the Ancient Greek: μύκης (''mukēs''), meaning "fungus" and the suffix (''-logia''), meaning "study." Pioneer mycologists included Elias Magnus Fries, Christiaan Hendrik Persoon, Heinrich Anton de Bary, Elizabeth Eaton Morse, and Lewis David de Schweinitz.
