''Lopadium'' (commonly known as the granular lichen) is a genus of lichen-forming fungi in the monotypic family Lopadiaceae, which is in the order Lecideales. The genus contains 10 species. ''Lopadium'' was circumscribed by German lichenologist Gustav Wilhelm Körber Gustav Wilhelm Körber (10 January 1817, Hirschberg – 27 January 1885, Breslau) was a German lichenologist.

Josef Hafellner
Josef Hafellner (1951– ) is an Austrian mycologist and lichenologist. He was awarded the Acharius Medal in 2016 for his lifetime contributions to lichenology. Before his retirement, he was a professor at the Karl-Franzens-Universität in Graz. Hafellner started developing an interest in lichens while he was a student at this institution, studying under Josef Poelt. He earned a master's degree in 1975 and a PhD in 1978, defending a doctoral thesis about the genus '' Karschia''. In 2003, Hafellner received his habilitation. By this time, he had studied with French lichenologist André Bellemère (1927–2014) at Saint-Cloud, where he learned techniques of transmission electron microscopy and how their application in studying asci could be used in lichen systematics. His 1984 work ''Studien in Richtung einer natürlicheren Gliederung der Sammelfamilien Lecanoraceae und Lecideaceae'' has been described as "probably the single most influential publication in lichen systematics in t ...

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 ...

Gustav Wilhelm Körber
Gustav Wilhelm Körber (10 January 1817, Hirschberg – 27 January 1885, Breslau) was a German lichenologist. He studied natural sciences in Breslau and Berlin, obtaining his PhD in 1839 with the thesis ''De gonidiis lichenum''. After graduation, he served as an instructor at the "Elisabethanum" in Breslau, and from 1862, worked as a private teacher.

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 ...

Monotypic
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda. ...

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] |

Lopadium Subcoralloideum
Ulubad or Uluabat, in the Byzantine period Lopadion ( grc, Λοπάδιον), Latinized as Lopadium, is a settlement near the town of Karacabey in the Bursa Province of northwestern Turkey. It was sited on the ancient Miletouteichos. History Uluabat is located on the banks of the Mustafakemalpaşa River (ancient and medieval Rhyndacus). It is first mentioned by Theodore of Stoudios in one of his letters, as the site of a ''xenodocheion'' (caravanserai). By the late 11th century, it featured a market town. The existence of a 4th-century bridge carrying the road between Cyzicus on the Sea of Marmara to the interior of Asia Minor made it a place of some strategic importance, especially in the wars of the Komnenian emperors against the Seljuk Turks in the 11th–12th centuries, during which it is best known. Alexios I Komnenos (r. 1081–1118) fought the Turks in the vicinity, and in 1130, his successor John II Komnenos (r. 1118–43) built there a great fortress which became th ...
