Chrysotrichaceae
Chrysotrichaceae is a family of lichenized fungi in the order Arthoniales. Member of this family have a widespread distribution, but are especially prevalent in tropical areas. "Chrysothrichaceae" and "Chrysothricaceae" are alternative spellings that have been used in some older publications; the latter was used by Alexander Zahlbruckner in the protologue publication. Both of these spellings are considered incorrect, and the current spelling has been formalised following a proposal for conservation of Chrysotrichaceae against Pulverariaceae (an earlier synonym A synonym is a word, morpheme, or phrase that means precisely or nearly the same as another word, morpheme, or phrase in a given language. For example, in the English language, the words ''begin'', ''start'', ''commence'', and ''initiate'' are a ...).

Arthoniales
The Arthoniales is the second largest order of mainly crustose lichens, but fruticose lichens are present as well. The order contains around 1500 species, while the largest order with lichenized fungi, the Lecanorales, contains more than 14000 species. Classification The Arthoniales is one of two orders of the class Arthoniomycetes within the phylum Ascomycota. The order includes seven families ( Andreiomycetaceae, Arthoniaceae, Chrysotrichaceae, Lecanographaceae, Opegraphaceae, Roccellaceae and Roccellographaceae). Lecanographaceae, Roccellographaceae, Opegraphaceae and Roccellaceae are well-supported families within Arthoniales, and they were circumscribed in 2011. Andreiomycetaceae was described as a new family by Hodkinson and Lendemer in 2013. The Arthoniales is the sister group to Dothideomycetes. Figure 1.

Chrysothrix
''Chrysothrix'' is a genus of lichen-forming fungi in the family Chrysotrichaceae. They are commonly called gold dust lichens or sulfur dust lichens,Field Guide to California Lichens, Stephen Sharnoff, Yale University Press, 2014, because they are bright yellow to greenish-yellow, sometimes flecked with orange, and composed entirely of powdery soredia.Brodo, I. M., S. D. Sharnoff, and S. Sharnoff. 2001. Lichens of North America. Yale University Press: New Haven. Apothecia An ascocarp, or ascoma (: ascomata), is the fruiting body ( sporocarp) of an ascomycete phylum fungus. It consists of very tightly interwoven hyphae and millions of embedded asci, each of which typically contains four to eight ascospores. As ... are never present in North American specimens. They grow on bark or rocks, generally in shaded habitats. They can sometimes be mistaken for sterile specimens of ''Chaenotheca'', which usually has pinhead apothecia on tiny stalks, or ''Psilolechia'', which us ...

Galbinothrix
''Galbinothrix'' is a fungal genus in the family Chrysotrichaceae. It is monotypic, containing the single species ''Galbinothrix caesiopruinosa'', a corticolous (bark-dwelling) lichen. Taxonomy Both the genus and species were described as new to science in 2018 by Andreas Frisch, Göran Thor, Kwang Hee Moon, and Yoshihito Ohmura. The type specimen was collected in Chichibu Tama Kai National Park (Nagano Prefecture) at an elevation of , where it was found growing on the smooth bark on an ''Alnus'' tree in a montane forest along the Shinano River. The genus name combines the Latin ''galbinus'' ("greenish-yellow") with the suffix ''thrix'', which alludes to its relationship with the genus ''Chrysothrix''; the species epithet refers to the ascomata, which are bluish grey ascomata and pruinose. Description ''Galbinothrix caesiopruinosa'' has a thin, discontinuous thallus that ranges in color from pale to dark greyish-green to yellowish-olive; the thallus patches, which are partly , m ...

Melarthonis
''Melarthonis'' is fungal genus in the family Chrysotrichaceae. It is a monotypic genus, containing the single species ''Melarthonis piceae'', a rare corticolous lichen. This lichen forms a very thin, almost invisible layer of tiny pale-green granules on tree bark, along with small black reproductive structures. It is known only from a single location in Hokkaido, Japan, where it was discovered growing on spruce trees in an old-growth forest. Taxonomy Both the genus and species were described as new to science in 2014 by Andreas Frisch and Göran Thor. The type specimen was collected from Mount Oakan ( Kushiro Province, Hokkaido) at an altitude of ; there, it was found growing on the bark of a spruce tree in an old-growth forest. It is only known to occur in the type locality. The genus name alludes to the black ascomata that are similar to those in genus ''Arthonia'', while the species epithet refers to the genus of the host tree (''Picea'').

Chrysothrix Xanthina
''Chrysothrix xanthina'' is a widely distributed species of leprose lichen in the family Arthoniaceae. It has a bright yellow to bright greenish-yellow, thin, granular thallus, and typically grows on bark, although it is infrequently found growing on rock. Taxonomy It was first scientifically described by Finnish lichenologist Edvard August Vainio in 1901 as ''Lepraria xanthina''. Klaus Kalb transferred it to the genus ''Chrysothrix'' in 2001. Kalb resurrected the species from synonymy with the lookalike ''Chrysothrix candelaris'' by virtue of its smaller granules and differences in chemistry: ''C. candelaris'' produces calycin, while ''C. xanthina'' makes pinastric acid. The granules made by ''C. xanthina'' are typically in the range 25–40 μm, while those of ''C. candelaris'' are 50–75 μm. Jack Laundon did not agree with the decision to promote this to a distinct species, noting "the absence of significant morphological characters, althoug ...

Arthoniomycetes
Arthoniomycetes are a class of ascomycete fungi. It includes two orders: Arthoniales and Lichenostigmatales. Most of the taxa in these orders are tropical and subtropical lichens. Systematics Phylogenetic analysis supports the monophyly of this class. Dothideomycetes is a sister group. Characteristics Taxa have apothecia, cup- or saucer- shaped ascoma in which the hymenium The hymenium is the tissue layer on the hymenophore of a fungal fruiting body where the cells develop into basidia or asci, which produce spores. In some species all of the cells of the hymenium develop into basidia or asci, while in oth ... is exposed at maturity.

Synonym (taxonomy)
In taxonomy, the scientific classification of living organisms, a synonym is an alternative scientific name for the accepted scientific name of a taxon. The Botanical nomenclature, botanical and Zoological nomenclature, zoological codes of nomenclature treat the concept of synonymy differently. * In nomenclature, botanical nomenclature, a synonym is a Binomial nomenclature, scientific name that applies to a taxon that now goes by a different scientific name. For example, Carl Linnaeus, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different Binomial nomenclature, binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conserved Name
A conserved name or ''nomen conservandum'' (plural ''nomina conservanda'', abbreviated as ''nom. cons.'') is a scientific name that has specific nomenclatural protection. That is, the name is retained, even though it violates one or more rules which would otherwise prevent it from being legitimate. ''Nomen conservandum'' is a Latin term, meaning "a name to be conserved". The terms are often used interchangeably, such as by the International Code of Nomenclature for algae, fungi, and plants, ''International Code of Nomenclature for Algae, Fungi, and Plants'' (ICN), while the ''International Code of Zoological Nomenclature'' favours the term "''conserved name''". The process for conserving botanical names is different from that for zoological names. Under the botanical code, names may also be "suppressed", ''nomen rejiciendum'' (plural ''nomina rejicienda'' or ''nomina utique rejicienda'', abbreviated as ''nom. rej.''), or rejected in favour of a particular conserved name, and combi ...

Alexander Zahlbruckner
Alexander Zahlbruckner (31 May 1860, Svätý Jur – 1938, Vienna) was an Austrian- Hungarian botanist who specialized in the study of lichens. Johann Babtist Zahlbruckner, an earlier Austrian botanist, was his grandfather. From 1878 to 1883 he studied at the University of Vienna, where his instructors included Anton Kerner von Marilaun and Julius Wiesner. Afterwards, he served as a voluntary assistant to Günther Beck von Mannagetta und Lerchenau at the Naturhistorisches Museum in Vienna, where he later attained the titles of assistant curator (from 1897), curator (from 1899) and head curator (from 1912). Starting with 1896 he edited exsiccata series, among them ''Kryptogamae exsiccatae editae a Museo Palatino Vindobonensi'', first together with Beck von Mannagetta und Lerchenau, and organised the exchange of specimens.Triebel, D. & Scholz, P. 2001–2024 ''IndExs – Index of Exsiccatae''. – Botanische Staatssammlung München: http://indexs.botanischestaatssammlung.de. – ...

Fungi
A fungus (: fungi , , , or ; or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and mold (fungus), molds, as well as the more familiar mushrooms. These organisms are classified as one of the kingdom (biology)#Six kingdoms (1998), traditional eukaryotic kingdoms, along with Animalia, Plantae, and either Protista or Protozoa and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of motility, mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropical
The tropics are the regions of Earth surrounding the equator, where the sun may shine directly overhead. This contrasts with the temperate or polar regions of Earth, where the Sun can never be directly overhead. This is because of Earth's axial tilt; the width of the tropics (in latitude) is twice the tilt. The tropics are also referred to as the tropical zone and the torrid zone (see geographical zone). Due to the overhead sun, the tropics receive the most solar energy over the course of the year, and consequently have the highest temperatures on the planet. Even when not directly overhead, the sun is still close to overhead throughout the year, therefore the tropics also have the lowest seasonal variation on the planet; "winter" and "summer" lose their temperature contrast. Instead, seasons are more commonly divided by precipitation variations than by temperature variations. The tropics maintain wide diversity of local climates, such as rain forests, monsoons, sa ...
