Multiclavula Ichthyiformis
''Multiclavula ichthyiformis'' is a species of terricolous (ground-dwelling) basidiolichen in the family Hygrophoraceae. Found in Costa Rica, it was formally described as a new species in 2007 by Matthew Nelsen, Robert Lücking, Loengrin Umaña, Marie Trest, and Susan Will-Wolf. The type collection was collected in the Macizo de la Muerte section of Tapantí National Park (Cartago Province) at an elevation of . Here, in a disturbed high-altitude peat bog in a rainforest, it was found growing on the ground along a brook and a road bank. The thallus of ''Multiclavula ichthyiformis'' is barely discernible as a greenish layer on the soil up to across, containing colonies of green algae (the photobiont, from the genus ''Coccomyxa'')) and fungal hyphae. The fruit bodies are fleshy, unbranched, and lanceolate, with a fishtail-like lamina. The species epithet ''ichthyiformis'' refers to this latter feature. Its basidiospores are smooth and spherical, thin-walled and hyaline, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robert Lücking
Robert Lücking (born 1964) is a German lichenologist. He is a leading expert on foliicolous lichens–lichens that live on leaves. Life and career Born in Ulm in 1964, Lücking earned both his master's (1990) and PhD degree (1994) at the University of Ulm. Both degrees concerned the taxonomy, ecology, and biodiversity of foliicolous lichens. His graduate supervisor was mycologist and bryologist Sieghard Winkler, who had previously studied epiphyllous (upper leaf-dwelling) fungi in El Salvador and Colombia. In 1996 Lücking was awarded the Mason E. Hale award for an "outstanding doctoral thesis presented by a candidate on a lichenological theme". His thesis was titled ''Foliikole Flechten und ihre Mikrohabitatpraferenzen in einem tropischen Regenwald in Costa Rica'' ("Foliicolous lichens and their microhabitat preferences in a tropical rainforest in Costa Rica"). In this work, Lücking recorded 177 foliicolous lichen species from the shrub layer in a Costa Rican tropical forest. L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lanceolate
The following is a list of terms which are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (a single leaf blade or lamina) or compound (with several leaflets). The edge of the leaf may be regular or irregular, may be smooth or bearing hair, bristles or spines. For more terms describing other aspects of leaves besides their overall morphology see the leaf article. The terms listed here all are supported by technical and professional usage, but they cannot be represented as mandatory or undebatable; readers must use their judgement. Authors often use terms arbitrarily, or coin them to taste, possibly in ignorance of established terms, and it is not always clear whether because of ignorance, or personal preference, or because usages change with time or context, or because of variation between specimens, even specimens from the same plant. For example, whether to call leaves on the same tree "acuminate", "lanceolate", or "linear" could ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Phyllobaeis Imbricata
''Phyllobaeis'' is a genus of lichen-forming fungi in the family Baeomycetaceae. It has six species. The genus was circumscribed by lichenologists Klaus Kalb and Claudia Gierl in 1993, with '' Phyllobaeis imbricata'' assigned as the type species. ''Phyllobaeis'' differs from ''Baeomyces'' by the production of the secondary chemical norstictic acid, as well as the tropical distribution of its species. Most species have a squamulose thallus, but the most recent addition to the genus–the Chinese species '' P. crustacea''–has a crustose thallus. Species *''Phyllobaeis crustacea'' – China *''Phyllobaeis erythrella'' *'' Phyllobaeis imbricata'' *''Phyllobaeis linearis'' *''Phyllobaeis rhodochroa'' *''Phyllobaeis rubescens ''Phyllobaeis'' is a genus of lichen-forming fungi in the family Baeomycetaceae.

Icmadophila Aversa
''Icmadophila'' is a genus of crustose lichen. The genus has a widespread distribution in the Northern Hemisphere and contains six species. The only species found in North America, ''Icmadophila ericetorum'', has a mint green crustose thallus that is dotted with bright pink apothecial disks, and is sometimes colloquially referred to as "fairy puke".Vitt, D, J Marsh, and R Bovey. 1994.

Dictyonema Glabratum
''Dictyonema'' is a genus of mainly tropical basidiolichens in the family Hygrophoraceae. The ''Dictyonema'' symbiosis Most lichens are a symbiosis between an ascomycete fungus and a photosynthetic green alga. However, a small percentage of lichens (approximately 10%) are cyanolichens and contain a photosynthetic cyanobacterium instead of green algae, and an even smaller number (less than 1%) are basidiolichens and contain a basidiomycete fungus instead of an ascomycete. This makes ''Dictyonema'' more closely related to mushrooms than it is to most other lichens. Taxonomy and naming The genus ''Dictyonema'' was first named in 1822 by Carl Adgardh and Carl Kunth after examining a novel fungus that was sent to them from Brazil.Kunth, CS, and CA Agardh. 1822. Synopsis Plantarum, Quas in Itinere ad Plagam Aequinoctialem Orbis Novi, Collegerunt Al. de Humboldt et Am. Bonpland (Paris). Volume 1, pg. 1.

Cladonia Confusa
''Cladonia'' is a genus of moss-like lichens in the family Cladoniaceae. They are the primary food source for reindeer/caribou. ''Cladonia'' species are of economic importance to reindeer-herders, such as the Sami in Scandinavia or the Nenets in Russia. Antibiotic compounds are extracted from some species to create antibiotic cream. The light green species ''Cladonia stellaris'' is used in flower decorations. Although the phylogeny of the genus ''Cladonia'' is still under investigation, two main morphological groups are commonly differentiated by taxonomists: the ''Cladonia'' morpho-type and the ''Cladina'' morpho-type. The ''Cladonia'' morpho-type has many more species, and is generally described as a group of squamulose (grow from squamules), cup-bearing lichens. The ''Cladina'' morpho-types are often referred to as forage lichens, mat-forming lichens, or reindeer lichens (due to their importance as caribou winter forage). ''Cladonia perforata'' ("perforate cladonia") is on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cladia Aggregata
''Cladia'' is a genus of lichenized fungi in the family Cladoniaceae. ''Cladia'' species have a crustose primary thallus and a fruticose, secondary thallus, often referred to as pseudopodetium. The type species of the genus, '' Cladia aggregata'', is widely distributed, occurring from South America, South Africa, Australasia and South-East Asia to southern Japan and India. Most of the other species are found in the Southern Hemisphere. Taxonomy ''Cladia'' was circumscribed by Finnish lichenologist William Nylander in 1870 with '' Cladia aggregata'' as the type species. Rex Filson created a separate family, the Cladiaceae, to contain the genus, but this is no longer used and the genus is classified in the family Cladoniaceae. An updated phylogeny of the Cladoniaceae was published in 2018. Molecular phylogenetic evidence showed that the genera ''Heterodea'' and ''Ramalinora'' were nested within ''Cladina'', so they are now synonyms. Because the name ''Heterodea'' predated ''Cladina ...

Micrometre
The micrometre ( international spelling as used by the International Bureau of Weights and Measures; SI symbol: μm) or micrometer (American spelling), also commonly known as a micron, is a unit of length in the International System of Units (SI) equalling (SI standard prefix "micro-" = ); that is, one millionth of a metre (or one thousandth of a millimetre, , or about ). The nearest smaller common SI unit is the nanometre, equivalent to one thousandth of a micrometre, one millionth of a millimetre or one billionth of a metre (). The micrometre is a common unit of measurement for wavelengths of infrared radiation as well as sizes of biological cells and bacteria, and for grading wool by the diameter of the fibres. The width of a single human hair ranges from approximately 20 to . The longest human chromosome, chromosome 1, is approximately in length. Examples Between 1 μm and 10 μm: * 1–10 μm – length of a typical bacterium * 3–8 μm – width of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
