Lepraria
''Lepraria'' is a genus of leprose crustose lichens that grows on its substrate like patches of granular, caked up, mealy dust grains.A taxonomic revision of the North American species of Lepraria s.l. that produce divaricatic acid, with notes on the type species of the genus L. incana, James C. Lendemer , Mycologia 103(6): 1216-1229/ref> Members of the genus are List of lichen common names and their genera, commonly called dust lichens.Field Guide to California Lichens, Stephen Sharnoff, Yale University Press, 2014, The main vegetative body (thallus) is made of patches of soredia (little balls of algae wrapped in fungus). There are no known mechanisms for sexual reproduction, yet members of the genus continue to speciate. Some species can form marginal lobes and appear squamulose. Because of the morphological simplicity of the thallus and the absence of sexual structures, the composition of lichen products (i.e., secondary metabolites made by lichens) are important character ...

Hertelidea
''Hertelidea'' is a genus of crustose lichens in the family Stereocaulaceae. Characteristics of the genus include carbon-black ring or outer margin (exciple) around the fruit body disc (apothecium), eight-spored, ''Micarea''-type asci and mostly simple, hyaline ascospores that lack a transparent outer layer. ''Hertelidea'' species mostly grow on wood, although less frequently they are found on bark or soil. While the type species, '' Hertelidea botryosa'', has a widespread distribution, most of the other species are found only in Australia. Taxonomy ''Hertelidea'' was circumscribed in 2004 by Christian Printzen and Gintaras Kantvilas to accommodate species that were formerly referred to as the "''Lecidea botryosa''" group. Four species were originally included: ''Hertelidea botryosa'', ''H. eucalypti'', ''H. geophila'', and ''H. pseudobotryosa''. ''H. aspera'' was transferred to the genus from ''Lecidea'' in 2005, while ''H. wankaensis'' was described as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

They form patches of radiating lobes or overlapping scales, with a well-developed upper cortex and no lower cortex. They grow on calcareous soil and rocks.

Boreal Ecosystem
A boreal ecosystem is an ecosystem with a subarctic climate located in the Northern Hemisphere, approximately between 50° to 70°N latitude. These ecosystems are commonly known as taiga and are located in parts of North America, Europe, and Asia. The ecosystems that lie immediately to the south of boreal zones are often called hemiboreal. There are a variety of processes and species that occur in these areas as well. The Köppen symbols of boreal ecosystems are Dfc, Dwc, Dfd, and Dwd. Boreal Species The species within boreal ecosystems varies as it consists of both terrestrial and aquatic habitats. The species composition include many generalized and less specialized feeders. From the equator to the poles, species richness decreases, and there is a negative relationship with species richness changes as climate changes. However, despite not being as biodiverse as tropical systems, this area has a variety of species. Boreal ecosystems are filled with a multitude of flora specie ...

Catalog Of Life
The Catalogue of Life is an online database that provides an index of known species of animals, plants, fungi, and microorganisms. It was created in 2001 as a partnership between the global Species 2000 and the American Integrated Taxonomic Information System. The Catalogue is used by research scientists, citizen scientists, educators, and policy makers. The Catalogue is also used by the Biodiversity Heritage Library, the Barcode of Life Data System, Encyclopedia of Life, and the Global Biodiversity Information Facility. The Catalogue currently compiles data fro165 peer-reviewed taxonomic databasesthat are maintained by specialist institutions around the world. , the COL Checklist lists 2,067,951 of the world's 2.2m extant species known to taxonomists on the planet at present time.
