Hypogymnia Papilliformis
''Hypogymnia papilliformis'' is a rare species of foliose lichen in the family Parmeliaceae. Found in China and the Russian Far East, it was formally described as a new species in 2015 by Bruce McCune, Svetlana Tchabanenko, and Xin Li Wei. The type specimen was collected by the second author in the Lazovsky Nature Reserve ( Primorsky Krai, Russia) at an altitude of ; here, in a mixed conifer–broadleaved forest, it was found growing on Korean pine (''Pinus koraiensis''). The lichen has also been recorded from a mixed forest in the mountains of Shaanxi Province in China, at an altitude of . The specific epithet ''papilliformis'' alludes to the papillose texture (i.e., covered with pimple-like structures) of the upper thallus surface. Secondary compounds Secondary metabolites, also called specialised metabolites, toxins, secondary products, or natural products, are organic compounds produced by any lifeform, e.g. bacteria, fungi, animals, or plants, which are not direc ...

Bruce McCune
Bruce Pettit McCune (born 1952) is an American lichenologist, botanist, plant ecologist, and software developer for analysis of ecological data. Biography McCune grew up in Cincinnati. He completed his freshman year of college at Lawrence University in Appleton, Wisconsin, and then transferred to the University of Montana in the autumn of 1971. There he graduated in 1974 with a bachelor's degree in botany. From 1971 to 1974 McCune and his then girlfriend, Patricia S. Muir, spent considerable time on Mount Sentinel, where they investigated lichens, mosses, and other plants. From 1974 to 1975 he travelled and also worked for two summers in Montana for the Bureau of Land Management. From 1976 to 1979 he was a graduate student at the University of Montana, where he graduated with a master's degree. In August 1979 he married Patricia Muir. She graduated in 1975 with a bachelor's degree in botany from the University of Montana. In 1979 the couple matriculated as graduate students at th ...

Secondary Metabolite
Secondary metabolites, also called specialised metabolites, toxins, secondary products, or natural products, are organic compounds produced by any lifeform, e.g. bacteria, fungi, animals, or plants, which are not directly involved in the normal growth, development, or reproduction of the organism. Instead, they generally mediate ecological interactions, which may produce a selective advantage for the organism by increasing its survivability or fecundity. Specific secondary metabolites are often restricted to a narrow set of species within a phylogenetic group. Secondary metabolites often play an important role in plant defense against herbivory and other interspecies defenses. Humans use secondary metabolites as medicines, flavourings, pigments, and recreational drugs. The term secondary metabolite was first coined by Albrecht Kossel, a 1910 Nobel Prize laureate for medicine and physiology in 1910. 30 years later a Polish botanist Friedrich Czapek described secondary metabolit ...

Hypogymnia
''Hypogymnia'' is a genus of foliose lichens in the family Parmeliaceae. They are commonly known as tube lichens, bone lichens, or pillow lichens. Most species lack rhizines (root-like attachment organs on the lower surface) that are otherwise common in members of the Parmeliaceae, and have swollen lobes that are usually hollow. Other common characteristics are relatively small spores and the presence of physodic acid and related lichen products. The lichens usually grow on the bark and wood of coniferous trees. ''Hypogymnia'' was proposed by lichenologist William Nylander, first as a subgenus of ''Parmelia'' in 1881, and 15 years later as a distinct genus of two species, including the widespread and common type species, '' Hypogymnia physodes''. It has since grown to about 90 recognized species. ''Hypogymnia'' has a centre of biodiversity in China, where many of its species are found. Taxonomy ''Hypogymnia'' was first created as subgenus of ''Parmelia'' by Finnish lichenolo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

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] |
Foliose Lichen
Foliose lichen is one of the morphological classes of lichens, which are complex organisms that arise from the symbiotic relationship between fungi and a photosynthetic partner, typically algae. This partnership allows lichen to live in diverse climates that can range from cold, dry mountains to wet, warm valleys. Lichens develop quite slowly with recorded growth rates of 0.01–27mm/year depending on the species. Their lifespan averages between 30 and 60 years. Lichens have a main body part called the thallus, which is composed of hyphae, and houses the cortex and medulla. The cortex contains the photosynthetic cells while the medulla allows for gas exchange and makes up the bulk of the lichen's thallus. There are three main types of lichens: crustose, foliose, and fruticose. Foliose lichen are characterised by flattened leafy thalli, and an upper and lower cortex. Many have numerous layers, which are stratified, and aid in identifying different types. Foliose lichens attach to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
