Sticta Rhizinata
''Sticta rhizinata'' is a species of foliose lichen in the family Peltigeraceae. Found in Colombia, it was formally described by Bibiana Moncada and Robert Lücking in 2012. It is a member of the '' Sticta weigelii'' species complex. The type specimen was collected in Chingaza National Natural Park ( Cundinamarca) at an altitude of . The lichen is only known to occur in the Andes of Colombia at altitudes between . Here it grows on the ground, often associated with bryophytes of the genera '' Plagiochila'', ''Frullania'', '' Metzgeria'', ''Campylopus'', and ''Dicranum''. Frequent lichen associates include '' Everniastrum'', ''Hypotrachyna'', and ''Peltigera''.

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] |
Metzgeria
''Metzgeria'' is a genus of thalloid liverworts in the family Metzgeriaceae. Taxonomy The genus was named in honor of Johann Metzger (1771–1844), a German copper engraver and art restorer from Staufen im Breisgau, in Baden-Württemberg, a friend of Giuseppe Raddi and pupil of the great Florentine engraver Raffaello Sanzio Morghen (1753–1833).K.

PhD thesis, Albert-Ludwigs-Universität, Freiburg. Species Approximately 120 to 200 species of ''Metzgeria'' have been described. Species may be either monoicous or dioicous Dioicy () is a sexual system where archegonia and antheridia are produced on separate gametophytes. It is one of the two main sexual systems in bryophytes.

Sticta
''Sticta'' is a genus of lichens in the family Peltigeraceae. The genus has a widespread distribution, especially in tropical areas, and includes about 114 species. These lichens have a leafy appearance, and are colored brown or black. ''Sticta'' species with cyanobacteria as photobionts can fix nitrogen from the atmosphere, and due to their relative abundance and high turnover, they contribute appreciably to the rainforest ecosystem. They are commonly called spotted felt lichens. Description The vegetative bodies of the ''Sticta'', the thalli, are foliose, or leafy in appearance. They typically have dimensions of in diameter, although specimens with diameters of up to have been recorded. The lobes are rounded, and the upper surface is black or brown, while the lower surface has a light to dark brown layer of fine hairs (a ), with a few craters, called . Thalli often smell of shrimp or fish. The vegetative reproductive structures called isidia or soredia are often present on s ...

Rhizine
In lichens, rhizines are multicellular root-like structures, arising mostly from the lower surface. A lichen with rhizines is termed rhizinate, while a lichen lacking rhizines is termed erhizinate. Rhizines serve only to anchor the lichen to their substrate; they do not absorb nutrients as do plant roots. Characteristics of the rhizines are used to identify lichens, for example: whether they are dense or sparse, whether they are uniformly distributed or clumped in specific areas, and whether they are straight or branched. Only foliose lichens may possess rhizines, not crustose or fruticose lichens, which lack a lower cortex. Rhizohyphae are a type of attachment structure on some lichens. Rhizohyphae are more slender than rhizines and are one cell thick in diameter. Rhizohyphae often occur as a felt-like hyphal mass. See also *Rhizoid Rhizoids are protuberances that extend from the lower epidermal cells of bryophytes and algae. They are similar in structure and function to the ro ...

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] |
Peltigera
''Peltigera'' is a genus of approximately 100 species of foliose lichens in the family Peltigeraceae. Commonly known as the dog or pelt lichens, species of ''Peltigera'' are often terricolous (growing on soil), but can also occur on moss, trees, rocks, and many other substrates in many parts of the world. Most species of ''Peltigera'' have the cyanobacterium ''Nostoc'' as the dominant photobiont but some have the algae '' Coccomyxa.'' The presence of both a green alga and a cyanobacterium makes some tripartite; in this case they show cephalodium growths containing the third partner, ''Nostoc''. Because of their ability to fix nitrogen from the atmosphere, such lichens are influential in soil composition and generation. Description Species of ''Peltigera'' are foliose, with broad lobed thalli. Although the size of the thalli is variable and species-dependent, in some species the thalli can grow quite large, up to 30 cm in diameter.Vitikainen O. (1994). (1998). Taxonomic no ...

''Dicranum'' is a genus of mosses, also called wind-blown mosses or fork mosses. These mosses form in densely packed clumps. Stems may fork, but do not branch. In general, upright stems will be single but packed together. ''Dicranum'' is distributed globally. In North America these are commonly found in Jack pine or Red pine stands.

Campylopus
''Campylopus'' is a genus of 180 species of haplolepideous mosses (Dicranidae) in the family Leucobryaceae. The name comes from the Greek ''campylos'', meaning curved, and ''pous'', meaning foot, referring to the setae which curve downwards. Distribution The genus is represented worldwide, with species found in North America, Mexico, West Indies, Central America, South America, Europe, Asia, Africa, Atlantic Islands, Pacific Islands, and Australia. ''Campylopus bicolor'' is an example found in Australia. The North American list of species from the genus was revised by Jan-Peter Frahm in 1980. This was based on his own study of over 1,000 herbarium specimens. The most recent checklist of the mosses of North America lists 18 species as being present in North American flora. However, due to a misidentification, there are only 17 accepted species in the region.
