Crustospathula
''Crustospathula'' is a genus of five species of crustose lichens in the family Malmideaceae. They are characterized by their stalked and sometimes branched cartilaginous soredia and ''Bacidia''-like apothecia. Taxonomy ''Crustospathula'' was circumscribed by lichenologist André Aptroot in 1998, with '' Crustospathula cartilaginea'' as the type species. This species was discovered by Aptroot in Madang Province, Papua New Guinea in an undisturbed tropical lowland rain forest. It was, according to Aptroot, the known instance of a crustose lichen with stalked, cartilaginous, labriform soralia. For this reason, it could not be assigned to any known genera, and ''Crustospathula'' was created to hold it. Aptroot initially assigned the genus tentatively to the family Bacidiaceae, because of the resemblance of generative structures with certain species of ''Bacidia''. It was later in the Ramalinaceae, until molecular phylogenetic analysis determined that its true placement belonged ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Malmideaceae
Malmideaceae is a family of crustose and corticolous lichens in the order Lecanorales. It contains eight genera and about 70 species. Taxonomy Malmideaceae was created in 2011 to accommodate a group of species, formerly placed in genus ''Malcolmiella'' (family Pilocarpaceae), that molecular phylogenetics showed to be a distinct lineage and worthy of recognition at the family level. The genus ''Savoronala'', containing the single African species '' S. madagascariensis'', was added to the family in 2013, while another monotypic genus '' Kalbionora'' was added in 2017. Description Malmideaceae is similar to Pilocarpaceae, but can be distinguished from that family by thallus organization and ascus structure. ''Malmidea'' species have a thallus made of goniocysts–spherical aggregations of photobiont cells surrounded by short-celled hyphae. This characteristic is quite rare in the Pilocarpaceae, only found in the monotypic genera '' Calopadiopsis'' and '' Pseudocalopadia''. Des ...

Crustospathula Amazonica
''Crustospathula amazonica'' is a species of corticolous (bark-dwelling), crustose lichen in the family Ramalinaceae. Found in South America, it was formally described as a new species in 2014 by lichenologists André Aptroot, Marcela Cáceres, and Einar Timdal. The type specimen was collected by the first two authors from the Parque Natural Municipal de Porto Velho (Rondônia, Brazil), where it was found growing on the smooth bark of a tree in a primary rainforest. It also occurs in French Guiana and Peru, and tends to grow in association with lichens of the genus ''Porina'' and with members of the family Graphidaceae. The lichen has a film-like, green thallus consisting of fine, aggregated ; no prothallus is present.

Micrometre
The micrometre ( international spelling as used by the International Bureau of Weights and Measures; SI symbol: μm) or micrometer (American spelling), also commonly known as a micron, is a unit of length in the International System of Units (SI) equalling (SI standard prefix "micro-" = ); that is, one millionth of a metre (or one thousandth of a millimetre, , or about ). The nearest smaller common SI unit is the nanometre, equivalent to one thousandth of a micrometre, one millionth of a millimetre or one billionth of a metre (). The micrometre is a common unit of measurement for wavelengths of infrared radiation as well as sizes of biological cells and bacteria, and for grading wool by the diameter of the fibres. The width of a single human hair ranges from approximately 20 to . The longest human chromosome, chromosome 1, is approximately in length. Examples Between 1 μm and 10 μm: * 1–10 μm – length of a typical bacterium * 3–8 μm – width of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Molecular Phylogenetic
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.

Ascospore
An ascus (; ) 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 "bourrelet ...

Septum
In biology, a septum (Latin for ''something that encloses''; plural septa) is a wall, dividing a cavity or structure into smaller ones. A cavity or structure divided in this way may be referred to as septate. Examples Human anatomy * Interatrial septum, the wall of tissue that is a sectional part of the left and right atria of the heart * Interventricular septum, the wall separating the left and right ventricles of the heart * Lingual septum, a vertical layer of fibrous tissue that separates the halves of the tongue. *Nasal septum: the cartilage wall separating the nostrils of the nose * Alveolar septum: the thin wall which separates the alveoli from each other in the lungs * Orbital septum, a palpebral ligament in the upper and lower eyelids * Septum pellucidum or septum lucidum, a thin structure separating two fluid pockets in the brain * Uterine septum, a malformation of the uterus * Vaginal septum, a lateral or transverse partition inside the vagina * Intermuscular sep ...
