Lichinomycetes
Lichinales is the sole order of ascomycete fungi in the class Lichinomycetes. It contains three families: Gloeoheppiaceae (3 genera), Lichinaceae (43 genera), and Peltulaceae (1 genus). Most species are lichenized. Lichinales was proposed in 1986 by German lichenologists Aino Henssen and Burkhard Büdel. The class Lichinomycetes was created by Valérie Reeb, François Lutzoni and Claude Roux in 2004. A study published in late 2022 suggests that six classes of fungi, Candelariomycetes, Coniocybomycetes, Geoglossomycetes, Lichinomycetes, Sareomycetes, and Xylonomycetes, are all part of a clade that has a sister relationship with a clade containing Lecanoromycetes and Eurotiomycetes. Lichinomycetes is the oldest name among these orders, and so the authors used this name for the group. Phylogenomic analysis of a 481-genome set showed that as a group, the Lichinomycetes have relatively small genomes, and fewer metabolic gene clusters; one consequence of this is an inability to ...

Lichinaceae
The Lichinaceae are a family of ascomycete fungi. Most species are lichenized with cyanobacteria, and have a distribution largely in temperate regions. Taxonomy The family was circumscribed in 1854 by Finnish lichenologist William Nylander. His description of the family mentioned the obscure brown thallus resembling algae, with an overall morphology described as either filamentous or tufted (fruticose). The fruiting structures, the apothecia, are described as either endocarpous or biatorine. He included two tribes in the Lichinaceae: ''Ephebeae'', which contained the genera ''Ephebe'' and ''Gonionema'', and ''Lichineae'', which contained '' Lichina'', the type genus. In 1986, Aino Henssen and Burkhard Büdel proposed the order Lichinales to contain the Lichinaceae. In the 1980s and 1990s, several taxonomic and nomenclatural studies were the basis for the revision of many of the species in the family. Heppiaceae was a family proposed by Alexander Zahlbruckner in 1906 to co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lichina Pygmaea
''Lichina'' is a genus of lichens in the family Lichinaceae. The genus contains seven species. These cyanolichens include maritime species such as '' L. pygmaea'' or '' L. confinis'', in which the associated cyanobiont has been assigned to the genus '' Rivularia''. Furthermore, evidence of a high specificity of each mycobiont towards particular cyanobiont lineages in both species has been detected.

Ascomycota Orders
Ascomycota is a phylum of the kingdom Fungi that, together with the Basidiomycota, forms the subkingdom Dikarya. Its members are commonly known as the sac fungi or ascomycetes. It is the largest phylum of Fungi, with over 64,000 species. The defining feature of this fungal group is the "ascus" (), a microscopic sexual structure in which nonmotile spores, called ascospores, are formed. However, some species of the Ascomycota are asexual, meaning that they do not have a sexual cycle and thus do not form asci or ascospores. Familiar examples of sac fungi include morels, truffles, brewers' and bakers' yeast, dead man's fingers, and cup fungi. The fungal symbionts in the majority of lichens (loosely termed "ascolichens") such as ''Cladonia'' belong to the Ascomycota. Ascomycota is a monophyletic group (it contains all descendants of one common ancestor). Previously placed in the Deuteromycota along with asexual species from other fungal taxa, asexual (or anamorphic) ascomycetes a ...

Fungi
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, 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 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 organisms, named the ''Eumycota'' (''t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phylogenomic
Phylogenomics is the intersection of the fields of evolution and genomics. The term has been used in multiple ways to refer to analysis that involves genome data and evolutionary reconstructions. It is a group of techniques within the larger fields of phylogenetics and genomics. Phylogenomics draws information by comparing entire genomes, or at least large portions of genomes. Phylogenetics compares and analyzes the sequences of single genes, or a small number of genes, as well as many other types of data. Four major areas fall under phylogenomics: * Prediction of gene function * Establishment and clarification of evolutionary relationships * Gene family evolution * Prediction and retracing lateral gene transfer. The ultimate goal of phylogenomics is to reconstruct the evolutionary history of species through their genomes. This history is usually inferred from a series of genomes by using a genome evolution model and standard statistical inference methods (e.g. Bayesian inference or ...

Lecanoromycetes
Lecanoromycetes is the largest class of lichenized fungi. It belongs to the subphylum Pezizomycotina in the phylum Ascomycota.

Genera of uncertain placement The are several genera in the Lecanoromycetes that have not been placed into any order or family. These are: *''Argopsis'' – 1 sp. *''Ascographa ''Ascographa'' is a genus of fungi in the Helotiales order.

Pectin
Pectin ( grc, πηκτικός ': "congealed" and "curdled") is a heteropolysaccharide, a structural acid contained in the primary lamella, in the middle lamella, and in the cell walls of terrestrial plants. The principal, chemical component of pectin is galacturonic acid (a sugar acid derived from galactose) which was isolated and described by Henri Braconnot in 1825. Commercially produced pectin is a white-to-light-brown powder, produced from citrus fruits for use as an edible gelling agent, especially in jams and jellies, dessert fillings, medications, and sweets; and as a chemical stabiliser in fruit juices and milk drinks, and as a source of dietary fiber. Biology Pectin is composed of complex polysaccharides that are present in the primary cell walls of a plant, and are abundant in the green parts of terrestrial plants. Pectin is the principal component of the middle lamella, where it binds cells. Pectin is deposited by exocytosis into the cell wall via vesicles produc ...
