Neobrownliella
''Neobrownliella'' is a genus of crustose lichens in the subfamily Teloschistoideae of the family Teloschistaceae. It has five species. The genus was circumscription (taxonomy), circumscribed in 2015 by lichenologists Sergey Kondratyuk, John Alan Elix, Jack Elix, Ingvar Kärnefelt, and Arne Thell, with ''Neobrownliella brownlieae'' assigned as the type species. It is a segregate of the large genus ''Caloplaca''. Characteristics of ''Neobrownliella'' include a thallus that is continuous or areolate, the presence of anthraquinones as lichen products, a cortex (botany), cortical layer with a palisade , and the lack of a thick palisade cortical layer on the underside of the (the ring-shaped layer of tissue surrounding the hymenium). Two species were included in the original circumscription of the genus; an additional three species were added in 2020.

Neobrownliella Montisfracti
''Neobrownliella montisfracti'' is a species of saxicolous (rock-dwelling), crustose lichen in the family Teloschistaceae. It is found in Australia. The small lichen has dull pink to grey , characterised by completely immersed, reddish to pink-brown apothecia (fruiting bodies) and lacking soredia and isidia. Its areoles are closely pressed against the , with the apothecia containing small, elongated and narrowly rod-shaped conidia. Taxonomy The lichen was formally described as a new species in 2007 by the lichenologists Sergey Kondratyuk and Ingvar Kärnefelt. The epithet of the species, ''montisfracti'', alludes to its frequent presence near Broken Hill (''montis'' meaning "hill" and ''fractus'' meaning "broken" in Latin). The type specimen was collected in 2004 north of Northampton on the road to Port Gregory, where it was found growing on sandstone–ironstone rocks. The taxon was transferred to the newly proposed genus ''Neobrownliella'' in 2015. Description ''Neobrownli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neobrownliella Brownlieae
''Neobrownliella brownlieae'' is a species of saxicolous (rock-dwelling), crustose lichen in the family Teloschistaceae. It is widely distributed in Australia. Taxonomy The lichen was described as new to science in 2011 by Sergey Kondratyuk, John Elix, and Ingvar Kärnefelt. It was originally placed in the large genus ''Caloplaca''. The type specimen was collected above Lake Eucumbene, in New South Wales, where it was found growing on a granite boulder. The specific epithet ''brownlieae'' honours Australian botanist Sue Brownlie, who collected the type. The species was transferred to the newly circumscribed genus ''Neobrownliella'' in 2015, in which it is the type species. This segregate genus of ''Caloplaca'' is characterised by a thallus that is continuous or areolate, the presence of anthraquinones as lichen products, a cortical layer with a palisade paraplectenchyma, and the lack of a thick palisade cortical layer on the underside of the thalline exciple (the ring-shaped ...

Teloschistaceae
The Teloschistaceae are a large family of mostly lichen-forming fungi belonging to the class Lecanoromycetes in the division Ascomycota. The family, estimated to contain over 1800 species, was extensively revised in 2013, including the creation or resurrection of 31 genera. It contains three subfamilies: Xanthorioideae, Caloplacoideae, and Teloschistoideae. A fourth subfamily, Brownlielloideae, proposed in 2015, has been shown to be part of the Teloschistoideae. Genera This is a list of the genera contained within the Teloschistaceae, based on a 2020 review and summary of ascomycete classification.

John Alan Elix
John Alan (Jack) Elix (born 1941) emeritus professor in chemistry at the Australian National University, is an organic chemist who has contributed in many fields: lichenology, lichen chemotaxonomy, plant physiology and biodiversity and natural product chemistry. He has authored 2282 species names, and 67 genera in the field of mycology. Education His first degree, B.Sc., and his Ph.D were both in organic chemistry from the University of Adelaide. This was followed by post-doctoral years at the University of Cambridge and then a D.Sc. in natural products chemistry from the Australian National University. Career Elix spent a post doctoral year in 1966 at Cambridge, returning to Australia in 1967 to a lectureship in chemistry at the ANU. He retired as professor of chemistry in 2002, becoming professor emeritus. By 1975 he had already published several papers on the organic chemistry of lichens, and ultimately leading to work on the evolution, taxonomy and phylogeny of liche ...

Cortex (botany)
In botany, a cortex is an outer layer of a stem or root in a vascular plant, lying below the epidermis but outside of the vascular bundles. The cortex is composed mostly of large thin-walled parenchyma cells of the ground tissue system and shows little to no structural differentiation. The outer cortical cells often acquire irregularly thickened cell walls, and are called collenchyma cells. Plants Stems and branches In the three dimensional structure of herbaceous stems, the epidermis, cortex and vascular cambium form concentric cylinders around the inner cylindrical core of pith. Some of the outer cortical cells may contain chloroplasts, giving them a green color. They can therefore produce simple carbohydrates through photosynthesis. In woody plants, the cortex is located between the periderm (bark) and the vascular tissue (phloem, in particular). It is responsible for the transportation of materials into the central cylinder of the root through diffusion and may al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxa Named By John Alan Elix
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 in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lichen Genera
A lichen ( , ) is a composite organism that arises from algae or cyanobacteria living among filaments of multiple fungi species in a mutualistic relationship.Introduction to Lichens – An Alliance between Kingdoms . University of California Museum of Paleontology. Lichens have properties different from those of their component organisms. They come in many colors, sizes, and forms and are sometimes plant-like, but are not plants. They may have tiny, leafless branches ( fruticose); flat leaf-like structures ( foliose); grow crust ...
