Austroboletus Olivaceoglutinosus
''Austroboletus olivaceoglutinosus'' is a species of bolete fungus found in Sikkim in northeast India. It is so named for its sticky olive-green cap. Taxonomy ''Austroboletus olivaceoglutinosus'' was species description, described as new to science in 2015, after collections in subalpine forests in Sikkim. The species name is derived from the latin words ''oliva'' "olive" and ''glūtĕn'' "glue", and refers to the mushroom's cap. Limited genetic testing showed an affinity to ''Austroboletus fusisporus''. Description The olive cap is diameter and fades to green-yellow with age, particularly at the margins. It is conical in shape initially, becoming more convex but not flat, and often has a central boss. The cap surface is very sticky, and often has dead insects stuck to it. Like other boletoid fungi, it has pores rather than gills on the cap underside. The cap margin covers the spore-bearing surface under the cap completely in young specimens. The pores are yellow-white when youn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four ...

Tsuga Dumosa
''Tsuga dumosa'', commonly called the Himalayan hemlock or in Chinese, Yunnan tieshan (), is a species of conifer native to the eastern Himalayas. It occurs in parts of Nepal, India, Bhutan, Myanmar, Vietnam and Tibet. Within its native range the tree is used for construction as well as for furniture. In Europe and North America, it is occasionally encountered as an ornamental species and was first brought to the United Kingdom in 1838. Description ''Tsuga dumosa'' is a tree growing high and exceptionally to . The diameter at breast height is typically , but can be beyond . The crown on small trees is ovoid and their form is like that of pendulous bushes. Older trees tend to have multiple stems from one or two sinuous boles, especially in cultivation. The crown of mature trees is broad, irregular-pyramidal and open. The bark is a similar to that of an old larch: somewhat pinkish to grey-brown and heavily ridged with broad, shallow, flaky fissures. The branches are oblique o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Potassium Hydroxide
Potassium hydroxide is an inorganic compound with the formula K OH, and is commonly called caustic potash. Along with sodium hydroxide (NaOH), KOH is a prototypical strong base. It has many industrial and niche applications, most of which exploit its caustic nature and its reactivity toward acids. An estimated 700,000 to 800,000 tonnes were produced in 2005. KOH is noteworthy as the precursor to most soft and liquid soaps, as well as numerous potassium-containing chemicals. It is a white solid that is dangerously corrosive. Properties and structure KOH exhibits high thermal stability. Because of this high stability and relatively low melting point, it is often melt-cast as pellets or rods, forms that have low surface area and convenient handling properties. These pellets become tacky in air because KOH is hygroscopic. Most commercial samples are ca. 90% pure, the remainder being water and carbonates. Its dissolution in water is strongly exothermic. Concentrated aqueous so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Austroboletus Fusisporus
''Austroboletus'' is a genus of fungi in the family Boletaceae. The widely distributed genus contains 28 species that form mycorrhizal relationships with plants. Taxonomy E. J. H. Corner originally defined ''Austroboletus'' as a subgenus of ''Boletus'' in his 1972 work ''Boletus in Malaysia'', before it was raised to genus level in 1979 by mycologist Carl B. Wolfe. The type species is ''Austroboletus dictyotus'', a fungus originally described by Karel Bernard Boedijn in 1960 as a member of genus ''Porphyrellus''. The generic name ''Austroboletus'' means "southern bolete". In a 2014 molecular genetics study, Wu and colleagues defined 22 clades within the Boletaceae. They found the genus as understood to be polyphyletic – composed of two distinct lineages. One with pitted stipes, which remained as ''Austroboletus'', while those with smoother stipes were moved to '' Veloporphyrellus''. They delineated a subfamily Austroboletoideae, which contained genera with pitted spores, i ... [...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] |
Basidiomycota
Basidiomycota () is one of two large divisions that, together with the Ascomycota, constitute the subkingdom Dikarya (often referred to as the "higher fungi") within the kingdom Fungi. Members are known as basidiomycetes. More specifically, Basidiomycota includes these groups: mushrooms, puffballs, stinkhorns, bracket fungi, other polypores, jelly fungi, boletes, chanterelles, earth stars, smuts, bunts, rusts, mirror yeasts, and ''Cryptococcus'', the human pathogenic yeast. Basidiomycota are filamentous fungi composed of hyphae (except for basidiomycota-yeast) and reproduce sexually via the formation of specialized club-shaped end cells called basidia that normally bear external meiospores (usually four). These specialized spores are called basidiospores. However, some Basidiomycota are obligate asexual reproducers. Basidiomycota that reproduce asexually (discussed below) can typically be recognized as members of this division by gross similarity to others, by the form ...

Sikkim
Sikkim (; ) is a state in Northeastern India. It borders the Tibet Autonomous Region of China in the north and northeast, Bhutan in the east, Province No. 1 of Nepal in the west and West Bengal in the south. Sikkim is also close to the Siliguri Corridor, which borders Bangladesh. Sikkim is the least populous and second smallest among the Indian states. Situated in the Eastern Himalaya, Sikkim is notable for its biodiversity, including alpine and subtropical climates, as well as being a host to Kangchenjunga, the highest peak in India and third highest on Earth. Sikkim's capital and largest city is Gangtok. Almost 35% of the state is covered by Khangchendzonga National Park – a UNESCO World Heritage Site. The Kingdom of Sikkim was founded by the Namgyal dynasty in the 17th century. It was ruled by Buddhist priest-kings known as the Chogyal. It became a princely state of British India in 1890. Following Indian independence, Sikkim continued its protectorate stat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
