Stereocaulon Dactylophyllum
''Stereocaulon dactylophyllum'' is a species of saxicolous (rock-dwelling), fruticose lichen in the family Stereocaulaceae. It was first scientifically described by Heinrich Gustav Flörke in 1819. Flörke mentions that the original specimens were collected in 1797 on mossy rocks at the Rehberger Graben and near Sankt Andreasberg on the Harz Mountains, and also on the Fichtel Mountains. It is now known to be widely distributed, having been recorded in Asia, Europe, Greenland, eastern Canada, and the eastern and central United States. The lichen is characterised morphologically by the coralloid, highly branched phyllocladia. Chemically, it contains lichen products in the stictic acid complex, including atranorin, norstictic acid Norstictic acid is a depsidone produced as a secondary metabolites in lichen A lichen ( , ) is a composite organism that arises from algae or cyanobacteria living among filaments of multiple fungi species in a mutualistic relationship.

Morphology (biology)
Morphology is a branch of biology dealing with the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance (shape, structure, colour, pattern, size), i.e. external morphology (or eidonomy), as well as the form and structure of the internal parts like bones and organs, i.e. internal morphology (or anatomy). This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of gross structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Friedrich Burdach ...

Lichens Of North America
Irwin M. Brodo (born 1935) is an emeritus scientist at the Canadian Museum of Nature, in Ottawa, Ontario, Canada. He is an authority on the identification and biology of lichens. Irwin Brodo was honored in 1994 with an Acharius Medal presented to him by the International Association for Lichenology. Brodo did his undergraduate studies at Columbia University, and received a master's degree from Cornell University. He earned a Ph.D. in lichenology under the supervision of Henry Imshaug at Michigan State University. He later went on to teach at Université Laval and the University of Alaska, and he also supervised master's students at the University of Ottawa and Carleton University. Brodo's list of publications includes 75 research papers, 8 popular articles, 22 reviews and 6 editorials and obituaries. In 1993, Brodie was awarded the Mary E. Elliot Service Award for his meritorious service to the Canadian Botanical Association. One of Irwin Brodo's great achievements was the public ...

Species Fungorum
''Index Fungorum'' is an international project to index all formal names (scientific names) in the fungus kingdom. the project is based at the Royal Botanic Gardens, Kew, one of three partners along with Landcare Research and the Institute of Microbiology, Chinese Academy of Sciences. It is somewhat comparable to the International Plant Names Index (IPNI), in which the Royal Botanic Gardens is also involved. A difference is that where IPNI does not indicate correct names, the ''Index Fungorum'' does indicate the status of a name. In the returns from the search page a currently correct name is indicated in green, while others are in blue (a few, aberrant usages of names are indicated in red). All names are linked to pages giving the correct name, with lists of synonyms. ''Index Fungorum'' is one of three nomenclatural repositories recognized by the Nomenclature Committee for Fungi; the others are ''MycoBank'' and ''Fungal Names''. Current names in ''Index Fungorum'' (''Specie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spot Test (lichen)
A spot test in lichenology is a spot analysis used to help identify lichens. It is performed by placing a drop of a chemical on different parts of the lichen and noting the colour change (or lack thereof) associated with application of the chemical. The tests are routinely encountered in dichotomous keys for lichen species, and they take advantage of the wide array of lichen products produced by lichens and their uniqueness among taxa. As such, spot tests reveal the presence or absence of chemicals in various parts of a lichen. They were first proposed by the botanist William Nylander in 1866. Three common spot tests use either 10% aqueous KOH solution (K test), saturated aqueous solution of bleaching powder or calcium hypochlorite (C test), or 5% alcoholic ''p''-phenylenediamine solution (P test). The colour changes occur due to presence of particular secondary metabolites in the lichen. There are several other less frequently used spot tests of more limited use that are employed ...
