Cladonia Krogiana
''Cladonia krogiana'' is a species of fruticose lichen in the family Cladoniaceae, described to science in 2002. This lichen is characterised by its greyish-green to medium-brown (scaly) , forming cushions up to wide, with distinctive chemical components including barbatic acid and the rare xanthone compound chlorovinetorin. Originally discovered in southeastern Norway, ''C. krogiana'' has since been found in the Czech Republic and New Brunswick, Canada, typically growing on sun-exposed siliceous rock in periodically wet, open areas near forests and water bodies. Taxonomy Species description, Described as a new species in 2002 by Bjørn Petter Lofall and Einar Timdal, ''Cladonia krogiana'' was first identified from specimens collected by the authors near the southwestern side of Lake Franesjaen in Østfold, Norway. The botanical name, species epithet honours Hildur Krog for her contributions to lichen taxonomy (biology), taxonomy. Molecular phylogenetics studies show that ...

Holotype
A holotype is a single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany, an isotype is a duplicate of the holotype, where holotype and isotypes are often pieces from the same individual plant or samples from the same gathering. A holotype is not necessarily "typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
