Rhizoplaca Novomexicana
''Rhizoplaca novomexicana'' is a species of saxicolous lichen, saxicolous (rock-dwelling), crustose lichen in the family Lecanoraceae. Found in North America, the lichen was first species description, formally described as a new species in 1932 by Adolf Hugo Magnusson, as a member of the genus ''Lecanora''. Sergey Kondratyuk proposed a transfer to the genus ''Protoparmeliopsis'' in 2012. Steven Leavitt, Xin Zhao, and Helge Thorsten Lumbsch, H. Thorsten Lumbsch transferred it to the genus ''Rhizoplaca'' in 2015, when, following molecular phylogenetics analysis, they emended that genus to include three species previously placed in ''Lecanora''.

Saxicolous Lichen
A saxicolous lichen is a lichen that grows on rock. The prefix "sax" from the Latin means "rock" or "stone". Characteristics Saxicolous lichens exhibit very slow growth rates. They may develop on rock substrates for long periods of time, given the absence of external disturbances. The importance of the mineral composition of the rock substrate, as well as the elemental geochemistry Geochemistry is the science that uses the tools and principles of chemistry to explain the mechanisms behind major geological systems such as the Earth's crust and its oceans. The realm of geochemistry extends beyond the Earth, encompassing the e ... is also important to the distribution of saxicolous lichens, but the relationship between the substrate influence on lichens, either chemical or textural, is still obscure. Communities of saxicolous lichens are often species-rich in terms of number. References Lichenology {{lichen-stub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 scientific description of a newly encountered species, typically articulated through a scientific publication. Its purpose is to provide a clear description of a new species of organism and explain how it differs from species that have been previously described or related species. For a species to be considered valid, a species description must follow established guidelines and naming conventions dictated by relevant nomenclature codes. These include the International Code of Zoological Nomenclature (ICZN) for animals, the International Code of Nomenclature for algae, fungi, and plants (ICN) for plants, and the International Committee on Taxonomy of Viruses (ICTV) for viruses. A species description often includes photographs or other illustrations of type material and information regarding where this material is deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adolf Hugo Magnusson
Adolf Hugo Magnusson (1 March 188514 July 1964) was a Swedish naturalist who specialized in lichenology. He was a school teacher in Gothenburg from 1909 to 1948, but spent his spare time on the study of lichens. Magnusson published many monographs and floristic papers, specializing in crustose lichens. He formally described about 900 new taxa, specializing in the genera ''Lecidea'', ''Lecanora'', '' Caloplaca'', and '' Acarospora''. Early life and education Adolf Hugo Magnusson was born on 1 March 1885, in the parish of Gottröra, Uppland ( Stockholm County). His parents, Johan Adolf Magnusson, an elementary schoolmaster with a talent for practical work, and Sofia, née Olsson, were from Södermanland. His father, who died in 1935, was a skilled craftsman in various trades and passed on his practical abilities to his son. Despite the strictness of his father, which contributed to a difficult childhood for Adolf and his sister, Magnusson developed an early passion for collecting ...

Lecanora
''Lecanora'' is a genus of lichen commonly called rim lichens.Field Guide to California Lichens, Stephen Sharnoff, Yale University Press, 2014, Lichens in the genus '' Squamarina'' are also called rim lichens. Members of the genus have roughly circular fruiting discs (apothecia) with rims that have photosynthetic tissue similar to that of the nonfruiting part of the lichen body ( thallus). Other lichens with apothecia having margins made of thallus-like tissue are called lecanorine. It is in the family Lecanoraceae in the suborder Lecanorineae. Description ''Lecanora'' has a crustose thallus, photobiont, colourless ascospores and crystals in the amphothecium. Swiss lichenologist Rosmarie Honegger used electron microscopy in the late 1970s to investigate ascus structure in several major groups of lichen-forming fungi. She defined the ''Lecanora''-type ascus as one characterized by several distinctive features: (1) a non- amyloid, clear ascus wall that is encased in ...

Molecular Phylogenetics
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 phylogenetics, 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 (biology), 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 tre ...

Species Fungorum
''Index Fungorum'' is an international project to index all formal names (Binomial nomenclature, scientific names) in the fungus Kingdom (biology), kingdom. As of 2015, the project is based at the Royal Botanic Gardens, Kew, one of three partners along with Landcare Research New Zealand Limited, Landcare Research and the Institute of Microbiology, Chinese Academy of Sciences. It is somewhat comparable to the International Plant Names Index (IPNI), in which the Royal Botanic Gardens is also involved. A difference is that where IPNI does not indicate Correct name (botany), correct names, the ''Index Fungorum'' does indicate the status of a name. In the returns from the search page, a currently correct name is indicated in green, while others are in blue (a few, aberrant usages of names are indicated in red). All names are linked to pages giving the correct name, with lists of Synonym (taxonomy), synonyms. ''Index Fungorum'' is one of three nomenclatural repositories recognized b ...
