Xanthoparmelia Mougeotii
''Xanthoparmelia mougeotii'' is a species of foliose lichen belonging to the family Parmeliaceae. Description The lichen has a foliose thallus that is usually in diameter. It consists of flattened greenish-grey to yellowish-grey lobes (about 0.2–0.5 mm wide) that are closely attached to the substrate. The lower surface is dark brown to black and has short, simple rhizines that are 0.1–0.2 mm long. Apothecia are rare, with brown discs, and sorediate margins. The predominant secondary compounds are usnic acid, stictic acid, and norstictic acid. Habitat and distribution ''Xanthoparmelia mougeotii'' typically grows on rocks, particularly ones that are smooth, and on a vertical surface. It is often found in scree fields, rock outcrops, cliffs, on boulders, stones, pebbles or siliceous conglomerates. The lichen has a distribution in temperate In geography, the temperate climates of Earth occur in the middle latitudes (23.5° to 66.5° N/S of Equator), which ...

Serra De São Mamede
Serra de São Mamede ( en, Saint Mammes Range) is a mountain range in Portalegre District, Portugal. This range is named after Saint Mammes. Together with the Serra de Arraiolos, the Serra de São Mamede is one of the few places in the Alentejo region where there might be snow in the winter. This mountain range separates the drainage basin of the Tagus to the north from the basin of the Guadiana to the south. The main rivers that have their sources in this range are the Sever and Nisa, flowing towards the Tagus, as well as the Caia River and its tributary, the Arronches, flowing towards the Guadiana. The town of Marvão is an ancient fortified town located on a ridge of the range. Its emblematic castle is an archetype of medieval castle-building. It dates back to the times of the ''Reconquista'', the reconquest of the Iberian Peninsula from the Moors. Besides Marvão, Portalegre, Castelo de Vide, Arronches and Alegrete are other important towns in the area of the range. Des ...

Saxicolous Lichen
A saxicolous lichen is a lichen that grows on rock. The prefix "sax" from the Latin means "rock" or "stone". Characteristics Saxicolous lichens exhibit very slow growth rates. They may develop on rock substrates for long periods of time, given the absence of external disturbances. The importance of the mineral composition of the rock substrate, as well as the elemental geochemistry Geochemistry is the science that uses the tools and principles of chemistry to explain the mechanisms behind major geological systems such as the Earth's crust and its oceans. The realm of geochemistry extends beyond the Earth, encompassing the e ... is also important to the distribution of saxicolous lichens, but the relationship between the substrate influence on lichens, either chemical or textural, is still obscure. Communities of saxicolous lichens are often species-rich in terms of number. References Lichenology {{lichen-stub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Xanthoparmelia
''Xanthoparmelia'' (commonly known as green rock shields or rock-shield lichens) is a genus of foliose lichen in the family Parmeliaceae.Field Guide to California Lichens, Stephen Sharnoff, Yale University Press, 2014, ''Xanthoparmelia'' is synonymous with ''Almbornia'', ''Neofuscelia'', ''Chondropsis'', ''Namakwa'', ''Paraparmelia'', and ''Xanthomaculina''. This genus of lichen is commonly found in the United States, as well as Australia, New Zealand and Ecuador. The name means 'golden yellow parmelia'. The photobiont (photosynthetic partner) is ''Trebouxia'' (a genus of green algae). Identification Distinguishing between species involves how much they are attached to the substrate, whether or not isidia are present, lower surface color, and chemical spot tests. All members of the genus react to spot test as K-, KC+ yellow, with medulla reaction varying from species to species. Species Species include: * ''Xanthoparmelia chlorochroa'' * '' Xanthoparmelia conspersa'' (''Parme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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''.
