Cordieritidaceae
''Cordieritidaceae'' is a family of fungi in the order Cyttariales. Species in this family are saprobes or lichenicolous. Description The ascomata of Cordieritidaceae species are apothecial, and range in shape from disc-shaped, cup-shaped, funnel-shaped, to ear-shaped. They are either sessile or stipitate, sometimes arising from a common base or from branched stipes with a dark stroma, and they are sometimes covered with hairs.

Phacopsis
''Phacopsis'' is a genus of lichenicolous (lichen-dwelling) fungi. They are parasites of members of the large lichen family Parmeliaceae, of which they are also a member. Originally proposed by Edmond Tulasne in 1852 to contain 3 species, ''Phacopsis'' now contains 10 species, although historically, 33 taxa have been described in the genus. Many of the species are poorly known, some of them having been documented only from the type specimen. ''Phacopsis'' species appear as partially immersed, shiny brown to black apothecia that cause gall-like deformations on the thallus of the host lichen. Features of ''Phacopsis'' used to distinguish species from each other include the shape of their spores, and the colour and reaction of the hypothecium (a tissue layer under the spore-bearing hymenium) when stained using an iodine–starch test. Since ''Phacopsis'' fungi are usually restricted to living on hosts belonging to a single phylogenetic clade, the identity of the host lichen is an ...

Taxa Named By David Leslie Hawksworth
In biology, a taxon (back-formation from ''taxonomy''; plural 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. 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and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Leotiomycetes Genera
The Leotiomycetes are a class of ascomycete fungi. Many of them cause serious plant diseases. Systematics The class Leotiomycetes contains numerous species with an anamorph placed within the ''fungi imperfecti'' (deuteromycota), that have only recently found their place in the phylogenetic system. The older classifications placed Leotiomycetes into the Discomycetes clade ( inoperculate Discomycetes). Molecular studies have recently shed some new light to the still obscure systematics. Most scholars consider Leotiomycetes a sister taxon to Sordariomycetes in the phylogenetic tree of Pezizomycotina. Its division into subclasses have received strong support by the molecular data, but the overall monophyly of Leotiomycetes is dubious. The order Lichinodiales and family Lichinodiaceae, newly circumscribed in 2019 to contain the genus cyanolichen genus '' Lichinodium'', is the first known group of lichen-forming fungi in the Leotiomycetes.

Sticta
''Sticta'' is a genus of lichens in the family Peltigeraceae. The genus has a widespread distribution, especially in tropical areas, and includes about 114 species. These lichens have a leafy appearance, and are colored brown or black. ''Sticta'' species with cyanobacteria as photobionts can fix nitrogen from the atmosphere, and due to their relative abundance and high turnover, they contribute appreciably to the rainforest ecosystem. They are commonly called spotted felt lichens. Description The vegetative bodies of the ''Sticta'', the thalli, are foliose, or leafy in appearance. They typically have dimensions of in diameter, although specimens with diameters of up to have been recorded. The lobes are rounded, and the upper surface is black or brown, while the lower surface has a light to dark brown layer of fine hairs (a ), with a few craters, called . Thalli often smell of shrimp or fish. The vegetative reproductive structures called isidia or soredia are often present on s ...

Foliose Lichen
Foliose lichen is one of the morphological classes of lichens, which are complex organisms that arise from the symbiotic relationship between fungi and a photosynthetic partner, typically algae. This partnership allows lichen to live in diverse climates that can range from cold, dry mountains to wet, warm valleys. Lichens develop quite slowly with recorded growth rates of 0.01–27mm/year depending on the species. Their lifespan averages between 30 and 60 years. Lichens have a main body part called the thallus, which is composed of hyphae, and houses the cortex and medulla. The cortex contains the photosynthetic cells while the medulla allows for gas exchange and makes up the bulk of the lichen's thallus. There are three main types of lichens: crustose, foliose, and fruticose. Foliose lichen are characterised by flattened leafy thalli, and an upper and lower cortex. Many have numerous layers, which are stratified, and aid in identifying different types. Foliose lichens attach to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peltigera
''Peltigera'' is a genus of approximately 100 species of foliose lichens in the family Peltigeraceae. Commonly known as the dog or pelt lichens, species of ''Peltigera'' are often terricolous (growing on soil), but can also occur on moss, trees, rocks, and many other substrates in many parts of the world. Most species of ''Peltigera'' have the cyanobacterium ''Nostoc'' as the dominant photobiont but some have the algae '' Coccomyxa.'' The presence of both a green alga and a cyanobacterium makes some tripartite; in this case they show cephalodium growths containing the third partner, ''Nostoc''. Because of their ability to fix nitrogen from the atmosphere, such lichens are influential in soil composition and generation. Description Species of ''Peltigera'' are foliose, with broad lobed thalli. Although the size of the thalli is variable and species-dependent, in some species the thalli can grow quite large, up to 30 cm in diameter.Vitikainen O. (1994). (1998). Taxonomic no ...

Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.
