Mazaediothecium Mohamedii
''Mazaediothecium mohamedii'' is a species of corticolous (bark-dwelling) and crustose lichen in the family Pyrenulaceae. It is found in Peninsular Malaysia. Taxonomy The lichen was formally described as a new species in 2007 by Hiroshi Harada and Yoshikazu Yamamoto. The type specimen was collected by the first author from the Field Studies Centre of the University of Malaya (Gombak, Selangor) at an elevation of ; here, in a tropical rainforest, the lichen was growing on the trunk of a hardwood on the side of the road. It is only known to occur at the type locality. The species epithet ''mohamedii'' refers to Professor Haji Mohamed, who arranged the field survey where this specimen was collected. Description ''Mazaediothecium mohamedii'' has a dull, cracked, pale creamy yellow thallus that lacks a cortex. It has perithecioid ascomata (flask-shaped structures opened by a pore) measuring 0.2–0.5 mm in diameter and 0.2–0.7 mm high. The spore mass occurs in the osti ...

Mazaediothecium Uniseptatum
''Mazaediothecium uniseptatum'' is a species of calicioid lichen in the family Pyrenulaceae. Found in French Guiana, it was formally described as a new species in 2015 by Dutch lichenologist André Aptroot. The type specimen was collected near the village sentier Limonade in Saül at an altitude of ; here, in a mixed forest, the lichen was found growing on the higher trunk of a '' Protium'' tree. It has a dull, greyish-white thallus that lacks a cortex and is surrounded by a brown prothallus line. The apothecia are black but covered in their upper half with a golden yellow pruina; they are about 0.2 mm in diameter and up to 0.6 mm high. The asci soon disintegrate to form a mazaedium layer. Ascospores are pale grey with a shape ranging from ellipsoid to spindle-shaped (fusiform), and measure 7.0–12.0 by 5.0–7.5 μm; they contain a single septum In biology, a septum (Latin for ''something that encloses''; plural septa) is a wall, dividing a cavity or structur ...

Pyrenulaceae
The Pyrenulaceae are a family of fungi in the order Pyrenulales. The family was first named by German botanist Gottlob Ludwig Rabenhorst in 1870. Species in the family have a widespread distribution, but are especially prevalent in the tropics, where they grow lichenized with green algae The green algae (singular: green alga) are a group consisting of the Prasinodermophyta and its unnamed sister which contains the Chlorophyta and Charophyta/Streptophyta. The land plants (Embryophytes) have emerged deep in the Charophyte alga as ... on bark.

André Aptroot
André Aptroot (Heemskerk, 1961) is a Dutch mycologist and lichenologist. In 1993 he did his PhD at the University of Utrecht under the supervision of Robbert Gradstein (nl). His dissertation was titled "Systematic studies on pyrenocarpous lichens and related fungi". He specializes in fungi and lichens on which he has several hundreds of publications to his name. He has worked as curator at Centraalbureau voor Schimmelcultures (now Westerdijk Institute). Aptroot is the founder of the Consultancy for Bryology and Lichenology, which is located in Soest where there is a herbarium with a collection of lichens mainly from the Netherlands and the tropics. From 2008 he has been collection manager at Pinetum Blijdenstein (nl) in Hilversum. He is a member of the International Association for Lichenology and the American Bryological and Lichenological Society. He is a visiting professor at the Federal University of Mato Grosso do Sul in Campo Grande, Brazil. Because of Aptroot's bro ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Calicioid Lichen
Lichens are composite organisms made up of multiple species: a fungal partner, one or more photosynthetic partners, and sometimes a basidiomycete yeast. They are regularly grouped by their external appearance – a characteristic known as their growth form. Lichenologists have described a dozen of these forms: areolate, byssoid, calicioid, cladoniform, crustose, filamentous, foliose, fruticose, gelatinous, leprose, placoidioid and squamulose. Of these, crustose, foliose and fruticose are the most commonly encountered. With the exception of calicioid lichens, growth forms are based on the appearance of the thallus, which is the vegetative (non-reproductive) part of the lichen. In most species, this form is determined by the lichen's fungal partner, though in a small number, it is instead the photobiont that determines the lichen's morphology. In some growth forms, the outermost layer of the thallus consists of tightly woven fungal . This layer, known as the cortex, may be found o ...

Circumscription (taxonomy)
In biological taxonomy, circumscription is the content of a taxon, that is, the delimitation of which subordinate taxa are parts of that taxon. If we determine that species X, Y, and Z belong in Genus A, and species T, U, V, and W belong in Genus B, those are our circumscriptions of those two genera. Another systematist might determine that T, U, V, W, X, Y, and Z all belong in genus A. Agreement on circumscriptions is not governed by the Codes of Zoological or Botanical Nomenclature, and must be reached by scientific consensus. A goal of biological taxonomy is to achieve a stable circumscription for every taxon. This goal conflicts, at times, with the goal of achieving a natural classification that reflects the evolutionary history of divergence of groups of organisms. Balancing these two goals is a work in progress, and the circumscriptions of many taxa that had been regarded as stable for decades are in upheaval in the light of rapid developments in molecular phylogenetics ...

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.
