Speerschneidera
''Speerschneidera'' is a single-species genus of lichen-forming fungi in the family Leprocaulaceae. The genus was circumscribed by Italian botanist Vittore Benedetto Antonio Trevisan de Saint-Léon in 1861, with ''Speerschneidera euploca'' as the type species. This lichen was originally described by Edward Tuckerman in 1858 as ''Physcia euploca''. It is a crustose lichen found in the southern United States and Mexico. The genus name of ''Speerschneidera'' is in honour of (1825–1903), who was a German doctor, teacher and naturalist. He worked as a curator of Frederick Charles, Prince of Schwarzburg-Rudolstadt's natural history collection which later became the Natural History Museum in Rudolstadt Rudolstadt is a town in the German federal state Thuringia, with the Thuringian Forest to the southwest, and to Jena and Weimar to the north.

Vittore Benedetto Antonio Trevisan De Saint-Léon
Vittore Benedetto Antonio Trevisan de Saint-Léon (5 June 1818, in Padua – 8 April 1897, in Milan) was an Italian botanist who specialized in cryptogam, cryptogamic flora. During his career, he was a professor of natural history in Padua. In 1882 he was named president of the ''Accademia fisio-medica-statistica'' in Milan. In 1848 he circumscribed the genus ''Romanoa tamnoides, Romanoa'' (family Euphorbiaceae) and in 1861 named the genus ''Speerschneidera'' (family Ramalinaceae, Bacidiaceae). In 1888, he circumscribed the (Algae) genus ''Nocardia'' (family Nocardiaceae) that is now classed as a bacteria. Also, he is also the binomial authority, taxonomic authority of the fern genera ''Blechnopteris'' (synonym of ''Blechnum'' L.), ''Neurosorus'' (synonym of ''Coniogramme'' Fée,)and ''Oligocampia'' (synonym of ''Athyrium'' Roth).

Leprocaulaceae
Leprocaulaceae is a family of mostly lichen-forming fungi. It is the single family in the monotypic order Leprocaulales. Leprocaulaceae contains three genera and about 33 species. Taxonomy Both the family and the order were circumscribed by American lichenologists James Lendemer and Brendan Hodkinson in 2013. They studied sterile, crustose lichens previously classified in the genus ''Lepraria'' using molecular phylogenetic techniques. They redefined the genus '' Leprocaulon'' to include several crustose lichens that were previously placed in ''Lepraria'', and defined the new family and order to contain this genetically distinct grouping of species, including the genus ''Halecania''. ''Speerschneidera'' was included based on the results of a study published a year later. The authors suggested that Leprocaulales is sister to the Caliciales, although in a later phylogenetic study using a temporal approach, it appeared to be more closely related to the Teloschistales.

Edward Tuckerman
Edward Tuckerman (December 7, 1817 in Boston, Massachusetts – March 15, 1886) was an American botanist and professor who made significant contributions to the study of lichens and other alpine plants. He was a founding member of the Natural History Society of Boston and most of his career was spent at Amherst College. He did the majority of his collecting on the slopes of Mount Washington in the White Mountains of New Hampshire. Tuckerman Ravine was named in his honor. The standard botanical author abbreviation Tuck. is applied to species he described. Early life and education Tuckerman was the eldest son of a Boston merchant, also Edward Tuckerman, and Sophia (May) Tuckerman. He studied at Boston Latin School and then at his father's urging at Union College in Schenectady, which he entered as a sophomore and where he completed a BA in 1837 and to which he returned for his MA after taking a law degree at Harvard in 1839, traveling in Germany and Scandinavia, and making ...

Taxa Described In 1861
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 intr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monotypic Lecanorales Genera
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.'' ...

Lecanoromycetes
Lecanoromycetes is the largest class of lichenized fungi. It belongs to the subphylum Pezizomycotina in the phylum Ascomycota. The asci (spore-bearing cells) of the Lecanoromycetes most often release spores by rostrate dehiscence. 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.

Rudolstadt
Rudolstadt is a town in the German federal state Thuringia, with the Thuringian Forest to the southwest, and to Jena and Weimar to the north. The former capital of Schwarzburg-Rudolstadt, the town is built along the River Saale inside a wide valley surrounded by woods. Rudolstadt was founded in 776 and has had municipal law since 1326. The town's landmark is the Castle Heidecksburg which is enthroned on a hill above the old town. The former municipality Remda-Teichel was merged into Rudolstadt in January 2019. Rudolstadt was once well known because of the Anchor Stone Blocks of the Toy Company Richter and porcelain factories, beginning with the establishment of the Volkstedt porcelain manufacture in 1762. History Early history There is archeological evidence of a hill fort on the Weinberg in Oberpreilipp from the time of the late Urnfield culture and the early Iron Age. A Celtic settlement followed the Germanic one and the affiliation with the Duchy of Thuringia. From the 6t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frederick Charles, Prince Of Schwarzburg-Rudolstadt
Prince Frederick Charles of Schwarzburg-Rudolstadt (7 June 1736 – 13 April 1793) was a German Natural History collector, and from 1790 until his death the reigning Prince of Schwarzburg-Rudolstadt. Life Frederick Charles of Schwarzburg-Rudolstadt was born in Rudolstadt, the son of Prince Louis Günther II of Schwarzburg-Rudolstadt and his wife Sophie Henriette, born Countess Reuss of Untergreiz (1711–1771). As a child, he began his natural history collection, which later went to the Natural History Museum of Rudolstadt. In 1757, he created the ''Princely Natural History Collection'' at the Ludwigsburg Castle in Rudolstadt. The collection was later enlarged, and in the 19th century, it occupied seven rooms in the castle. One of the first supervisors of the collection was Christoph Ludwig Kämmerer. In 1919, the collection was moved to Heidecksburg Castle. Frederick Charles of Schwarzburg-Rudolstadt corresponded with Johann Heinrich Merck, among others, and let him ...

Crustose Lichen
Crustose lichens are lichens that form a crust which strongly adheres to the Substrate (biology), substrate (soil, rock, tree bark, etc.), making separation from the substrate impossible without destruction. The basic structure of crustose lichens consists of a cortex (botany), cortex layer, an algal layer, and a medulla. The upper cortex layer is differentiated and is usually pigmented. The algal layer lies beneath the cortex. The medulla fastens the lichen to the substrate and is made up of Fungus, fungal hyphae. The surface of crustose lichens is characterized by branching cracks that periodically close in response to climatic variations such as alternate wetting and drying regimes. Subtypes * Powdery – considered as the simplest subtype due to the absence of an organized thallus. :The thallus appears powdery. :E.g. Genera ''Lepraria'', ''Vezdaea'' * Endolithic – grows inside the rock, usually in interstitial spaces between mineral grains. The :upper cortex is usually d ...

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
