Anaptychia Ethiopica
''Anaptychia ethiopica'' is a species of lichen in the family Teloschistaceae. Found in East Africa, China, and Russia, it was formally described as a new species in 1976 by lichenologists Thomas Douglas Victor Swinscow and Hildur Krog. The type specimen was collected from Mount Bwahit (Begemder, Ethiopia), where it was found growing on moss. Description The lichen has a thallus that ranges in colour from brown to grey and forms an irregular mat loosely attached to its . The of the lichen are separate from each other and can be straight or slightly wedge-shaped, with both long and short side lobes. The upper part of the thallus has an uneven texture, with the lower part sometimes with -like ridges. The underside of the thallus is light-coloured and not covered by a protective layer. Notable features include soralia, which are structures that house soredia (reproductive propagules) and are mainly found at or near the tips of the lobes, but occasionally further back on the main bo ...

Thomas Douglas Victor Swinscow
Thomas Douglas (Dougal) Victor Swinscow (1917–1992) was the founder of the British Lichen Society and the scientific journal ''The Lichenologist''. He was also a member of the editorial team of the British Medical Journal and deputy editor from 1964 until 1977. Early life and education Swinscow's parents were Nellie (née Alleyne) and William Sprague Swinscow. As a child Swinscow explored his home area of Devon and developed his interest in natural history. He was educated at the private boys school Kelly College, Tavistock, Devon. He completed a bachelor's degree in medicine at St Thomas's Hospital Medical School in 1939 and subsequently became a licentiate of the Royal College of Physicians, London and was registered as a member of the Royal College of Surgeons. In 1962 he was awarded an M.Sc. degree University of London for his studies on the lichen '' Porina''. Career After finishing his medical qualification, and working as a house surgeon at Woking Hospital he joined th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hypha
A hypha (; ) is a long, branching, filamentous structure of a fungus, oomycete, or actinobacterium. In most fungi, hyphae are the main mode of vegetative growth, and are collectively called a mycelium. Structure A hypha consists of one or more cells surrounded by a tubular cell wall. In most fungi, hyphae are divided into cells by internal cross-walls called "septa" (singular septum). Septa are usually perforated by pores large enough for ribosomes, mitochondria, and sometimes nuclei to flow between cells. The major structural polymer in fungal cell walls is typically chitin, in contrast to plants and oomycetes that have cellulosic cell walls. Some fungi have aseptate hyphae, meaning their hyphae are not partitioned by septa. Hyphae have an average diameter of 4–6 μm. Growth Hyphae grow at their tips. During tip growth, cell walls are extended by the external assembly and polymerization of cell wall components, and the internal production of new cell membrane. ...

Caliciales
Caliciales is an order of mostly lichenized fungi in the class Lecanoromycetes. It consists of two families: Caliciaceae and Physciaceae, which together contain 54 genera and more than 1200 species. The order was circumscribed by American botanist Charles Edwin Bessey in 1907. Families and genera , Species Fungorum (in the Catalogue of Life) accepts 2 families, 56 genera, and 910 species in the Caliciales. *Caliciaceae ::'' Acolium'' – 5 spp. ::'' Acroscyphus'' – 1 sp. ::'' Allocalicium'' – 1 sp. ::''Amandinea'' – 83 spp. ::'' Australiaena'' – 1 sp. ::'' Baculifera'' – 18 spp. ::''Buellia'' – 201 spp. ::''Calicium'' – 36 spp. ::'' Chrismofulvea'' – 3 spp. ::'' Ciposia'' – 1 sp. ::'' Cratiria'' – 23 spp. ::'' Dermatiscum'' – 2 sp. ::'' Dermiscellum'' – 1 sp. ::'' Dimelaena'' – 10 spp. ::'' Diploicia'' – 6 spp. ::'' Diplotomma'' – 12 spp. ::''Dirinaria'' – 18 spp. ::'' Endohyalina'' – 10 sp. ::'' Fluctua'' – 1 sp. ::'' ...

Lichenicolous Fungus
A lichenicolous fungus is a member of a specialised group of fungi that live exclusively on lichens as their host organisms. These fungi, comprising over 2,000 known species across 280 genera, exhibit a wide range of ecological strategies, including parasitism, commensalism, and mutualism. They can be found in diverse environments worldwide, from tropical to polar regions, and play important roles in lichen ecology and biodiversity. Lichenicolous fungi are classified into several taxonomic groups, with the majority belonging to the Ascomycota and a smaller portion to the Basidiomycota. Their interactions with host lichens range from mild parasitism to severe pathogenicity, sometimes causing significant damage to lichen communities. While the study of lichenicolous fungi dates back to the mid-18th century, recent decades have seen significant advancements through modern research methods, including molecular techniques, metagenomics, and sophisticated imaging. These fungi show vary ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Byrranga Mountains
The Byrranga Mountains (; ''Gory Byrranga'') are a mountain range in the middle of the Taymyr Peninsula, Siberia, Russia. Even though they were first explored in 1736, the Byrranga Mountains are one of the least known areas of the Arctic. The climate is continental and harsh, with frequent blizzards in the winter. This mountain range falls into the Krasnoyarsk Krai administrative division of the Russian Federation and is part of the Great Arctic State Nature Reserve, the largest nature reserve in Russia. However, the area is very remote, there is almost no population, and access is very difficult for the lack of roads and settlements. Geography They are located north and west of Lake Taymyr and running for about 1,100 km, forming a looping curve that runs roughly in a southwest to northeast direction. The name is from Nganasan бъранга 'bəranga'''large rocky mountain.' The range has deep canyons and ravines, as well as a few small glaciers in its eastern zones. Th ...
