Allocetraria
''Allocetraria'' is a genus of lichenized fungi in the family Parmeliaceae. It consists of 12 species, with a center of distribution in China. Systematics The genus was circumscribed by Syo Kurokawa and Ming-Jou Lai in 1991, with three species: both '' A. ambigua'' and the type species '' A. stracheyi'' recombined from different genera, and a newly described species, '' A. isidiigera''. Sunsequent molecular phylogenetic analyses showed that ''Allocetraria'' forms a monophyletic group within the cetrarioid clade in the family Parmeliaceae. In 2017, Divakar and colleagues used a then-recently developed "temporal phylogenetic" approach to identify temporal bands for specific taxonomic ranks in the family Parmeliaceae, suggesting that groups of species that diverged within the time window of 29.45–32.55 million years ago represent genera. They proposed to synonymize ''Allocetraria'' (and several other genera) with ''Cetraria'', because the former group of specie ...

Allocetraria Corrugata
''Allocetraria corrugata'' is a species of foliose lichen in the family Parmeliaceae. It is found in high-elevation locations in Yunnan, China, where it grows on rocks with mosses. Taxonomy The lichen was described as a new species in 2015 by Rui-Fang Wang, Xin-Li Wei, and Jiang-Chun Wei. The type specimen was collected from Meili Snow Mountain at an altitude of . The specific epithet ''corrugata'' refers to the corrugated surfaces of the lobes. In 2017, Divakar and colleagues proposed to synonymize genus ''Allocetraria'' (and several other Parmeliaceae genera) with ''Cetraria'', which would result in a name change to ''Cetraria corrugata''. The proposal was rejected by later authorities. Description The lichen thallus comprises narrow, slightly inflated lobes measuring 1–4 mm wide and 200–450 μm thick. Its surface colour is green to greenish-yellow, and its has a strongly wrinkled texture. Apothecia are absent, but there are pycnidia that appear as small black dot ...

Parmeliaceae
The Parmeliaceae is a large and diverse family of Lecanoromycetes. With over 2700 species in 71 genera, it is the largest family of lichen-forming fungi. The most speciose genera in the family are the well-known groups: '' Xanthoparmelia'' ( 822 species), '' Usnea'' (355 species), ''Parmotrema'' ( 255 species), and '' Hypotrachyna'' (262 species). Nearly all members of the family have a symbiotic association with a green alga (most often '' Trebouxia'' spp., but '' Asterochloris'' spp. are known to associate with some species).Miadlikowska, J.

Fungi
A fungus (plural, : fungi or funguses) is any member of the group of Eukaryote, eukaryotic organisms that includes microorganisms such as yeasts and Mold (fungus), molds, as well as the more familiar mushrooms. These organisms are classified as a Kingdom (biology), 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 motility, 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 gro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Babington
Charles Cardale Babington (23 November 1808 – 22 July 1895) was an English botanist and archaeologist. He was elected a Fellow of the Royal Society in 1851. Babington was the son of Joseph Babington and Cathérine née Whitter, and a nephew of Thomas Babington Macaulay. He was educated at Charterhouse and St John's College, Cambridge, obtaining his Bachelor of Arts in 1830 and his Master of Arts in 1833. He overlapped at Cambridge with Charles Darwin, and in 1829 they argued over who should have the pick of beetle specimens from a local dealer.Charles Darwin to William Darwin Fox, 1 April 829 Darwin Correspondence Project,Letter no. 60, accessed on 19 August 2020. He obtained the chair of botany at the University of Cambridge in 1861 and wrote several papers on insects. He married Anna Maria Walker on 3 April 1866. Babington was a member of several scientific societies including the Botanical Society of Edinburgh, the Linnean Society of London (1853), the Geological Society ...

Atranorin
Atranorin is a chemical substance produced by some species of lichen. It is a secondary metabolite belonging to a group of compounds known as depsides. Atranorin has analgesic, anti-inflammatory, antibacterial, antifungal, cytotoxic, antioxidant, antiviral, and immunomodulatory properties. In rare cases, people can react allergic Allergies, also known as allergic diseases, refer a number of conditions caused by the hypersensitivity of the immune system to typically harmless substances in the environment. These diseases include hay fever, food allergies, atopic derm ... to atranorin. References Further reading * * * * Polyphenols Lichen products {{organic-compound-stub ...
