Gassicurtia Omiae
''Gassicurtia omiae'' is a species of corticolous (bark-dwelling), crustose lichen in the family Caliciaceae. Found in Thailand, it was formally described as a new species in 2009 by lichenologist Klaus Kalb. The species epithet ''omiae'' honours Mrs. W. Saipunkaew ("Om"), who assisted the author as a guide and discovered the species in the field.

Klaus Kalb
Klaus Kalb (born 1942) is a German lichenologist and an authority on tropical lichens. Biography Klaus Kalb was born in Nuremberg in 1942 and grew up in southern Bavaria. From 1960 to 1965 he studied biology, chemistry, and geography at the University of Erlangen–Nuremberg. Kalb was greatly interested in lichens and decided to pursue a doctoral degree; his thesis work was about lichen communities in the Ötztal Alps. From 1978–1981 he was a teacher at the Colégio Visconde de Porto Seguro in São Paulo, Brazil. This position afforded him the opportunity to initiate research into tropical lichens. Kalb earned his habilitation from the University of Regensburg in 1989, becoming an associate professor with that institution. In 2014, the University of Wisconsin herbarium purchased Kalb's lichen collection of 60,000 specimens for $75,000. With the acquisition of Kalb's collection, rich in tropical and European specimens, the herbarium houses about 70% of the world's know ...

Queen Sirikit Botanic Garden
Queen Sirikit Botanic Garden (QSBG) is a botanical garden in Mae Rim District, Chiang Mai Province, Thailand. It was opened in 1993 and is maintained under the auspices of the Botanical Garden Organization (BGO) of the Ministry of Natural Resources and Environment. Originally called the ''Mae Sa Botanic Garden'', it was renamed for Sirikit, Queen of Thailand, in 1994. The site is home to twelve greenhouses, placing the establishment among Thailand's largest glasshouse complexes. QSBG spreads over a vast area, from a hilly region near to the river Mae Sai (at an elevation of approx. ) to the site's highest point, at . Evergreen and dipterocarp trees occupy lower elevations, while pine forest is found in higher areas. QSBG displays plants and flowers year round. It was Thailand’s first botanical garden built according to international standards. It focuses on strengthening ''ex situ'' conservation of valuable Thai flora. The breeding programs for native Thai orchids are some of ... [...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 ...

Caliciaceae
The Caliciaceae are a family of mostly lichen-forming fungi belonging to the class Lecanoromycetes in the division Ascomycota. Although the family has had its classification changed several times throughout its taxonomic history, the use of modern molecular phylogenetic methods have helped to establish its current placement in the order Caliciales. Caliciaceae contains 36 genera and about 600 species. The largest genus is ''Buellia'', with around 300 species; there are more than a dozen genera that contain only a single species. Most Caliciaceae grow on bark, dead wood, or rocks. Some members of this family, particularly those of the type genus, ''Calicium'', are characterized by the presence of thin-walled and short-lasting asci (spore-bearing cells) and a mazaedium, which is an accumulation of loose, maturing spores covering the surface of the fruiting body. The resulting passive spore dispersal is relatively rare amongst the Ascomycota. The mazaedium, usually black, either ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Botanical Name
A botanical name is a formal scientific name conforming to the '' International Code of Nomenclature for algae, fungi, and plants'' (ICN) and, if it concerns a plant cultigen, the additional cultivar or Group epithets must conform to the ''International Code of Nomenclature for Cultivated Plants'' (ICNCP). The code of nomenclature covers "all organisms traditionally treated as algae, fungi, or plants, whether fossil or non-fossil, including blue-green algae ( Cyanobacteria), chytrids, oomycetes, slime moulds and photosynthetic protists with their taxonomically related non-photosynthetic groups (but excluding Microsporidia)." The purpose of a formal name is to have a single name that is accepted and used worldwide for a particular plant or plant group. For example, the botanical name ''Bellis perennis'' denotes a plant species which is native to most of the countries of Europe and the Middle East, where it has accumulated various names in many languages. Later, the plant was intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gassicurtia
''Gassicurtia'' is a genus of lichenized fungi in the family Caliciaceae. Taxonomy The genus was circumscribed by French botanist Antoine Laurent Apollinaire Fée in Essai Crypt. Exot. (Paris) 1: XLVI, 100 in 1825. The genus name of ''Gassicurtia'' is in honour of Louis Claude Cadet de Gassicourt (1731–1799) who was a French chemist who synthesised the first organometalic compound. It was later resurrected by Bernhard Marbach in his 2000 monograph on ''Buellia'' sensu lato. The genus contains species that are part of the tropical ''Buellia'' group with 2-celled ascospores, and which lack algae in the margin. Species , Species Fungorum ''Index Fungorum'' is an international project to index all formal names (scientific names) in the fungus kingdom. the project is based at the Royal Botanic Gardens, Kew, one of three partners along with Landcare Research and the Institute of M ... accepts 30 species in the genus ''Gassicurtia'': *'' Gassicurtia acidobaeomyceta'' (200 ...

Lichen Product
Lichen products, also known as lichen substances, are organic compounds produced by a lichen. Specifically, they are secondary metabolites. Lichen products are represented in several different chemical classes, including terpenoids, orcinol derivatives, chromones, xanthones, depsides, and depsidones. Over 800 lichen products of known chemical structure have been reported in the scientific literature, and most of these compound are exclusively found in lichens. Examples of lichen products include usnic acid (a dibenzofuran), atranorin (a depside), lichexanthone (a xanthone), salazinic acid (a depsidone), and isolichenan, an α-glucan. Many lichen products have biological activity, and research into these effects is ongoing. Lichen products accumulate on the outer walls of the fungal hyphae, and are quite stable. Crystal deposits can be visualised using scanning electron microscopy. For this reason, even very old herbarium specimens can be analysed. The amount of lichen products i ...
