Cladonia Cayennensis

	Cladonia Cayennensis ''Cladonia cayennensis'' is a species of fruticose lichen in the family Cladoniaceae. It is found in French Guiana, although the authors suggest that its distribution might be more widespread. Taxonomy The lichen was formally described as a new species in 2013 by the lichenologists Teuvo Ahti and Harrie Sipman. The type specimen was collected by André Aptroot from the botanical garden in Cayenne, where it was found growing on palm. Description ''Cladonia cayennensis'' is characterised by a durable , which is the main vegetative body of the lichen. This thallus comprises flat to slightly curved, scale-like segments known as , typically measuring 1–2 mm in width. These squamules are soft and delicate, with rounded edges that are either smooth or slightly divided. The upper surface of the squamules presents a greenish-brown colour, while the underside is white, with a fluffy or cotton-like appearance. This underside is loosely covered with soredia, especially along ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Teuvo Ahti Teuvo ("Ted") Tapio Ahti (born 1934) is a Finnish botanist and lichenologist. He has had a long career at the University of Helsinki that started in 1963, and then following his retirement in 1997, at the Botanical Museum of the Finnish Museum of Natural History. Known as a specialist of the lichen family Cladoniaceae, Ahti has published more than 280 scientific publications. A ''Festschrift'' was dedicated to him in 1994, and in 2000 he was awarded the prestigious Acharius Medal for lifetime contributions to lichenology. Education and career Ahti started developing an interest in botany at the age of 15, when he worked on a class project involving collecting 100 species of plants. His attention turned to lichens when a classmate who had worked for Veli Räsänen pointed them out during a birdwatching excursion in Helsinki. His interest was further fuelled when a couple of years later, he had to pass a test on identification of forest floor lichens and bryophytes as part of ...

picture info	Podetia A podetium (plural: podetia) is the upright secondary thallus in ''Cladonia'' lichens. It is a hollow stalk extending from the primary thallus. Podetia can be pointed stalks, club like, cupped, or branched in shape and may or may not contain the ascocarp, the fruiting body, of the lichen. It is not considered part of the primary thallus as it is a fruiting structure for reproduction Reproduction (or procreation or breeding) is the biological process by which new individual organisms – "offspring" – are produced from their "parent" or parents. Reproduction is a fundamental feature of all known life; each individual or .... A lichen can be described as "podetiate" when it forms a podetium.

	Cladonia ''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 o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
