Neofuscelia
''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'' (''Par ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Section (biology)
In biology a section ( la, sectio) is a taxonomic rank that is applied differently in botany and zoology. In botany Within flora (plants), 'section' refers to a ''botanical'' rank below the genus, but above the species: * Domain > Kingdom > Division > Class > Order > Family > Tribe > Genus > Subgenus > Section > Subsection > Species In zoology Within fauna (animals), 'section' refers to a ''zoological'' rank below the order, but above the family: * Domain > Kingdom > Phylum > Class > Order > Section > Family > Tribe > Genus > Species In bacteriology The International Code of Nomenclature for Bacteria The International Code of Nomenclature of Prokaryotes (ICNP) formerly the International Code of Nomenclature of Bacteria (ICNB) or Bacteriological Code (BC) governs the scientific names for Bacteria and Archaea.P.

Xanthoparmelia Scabrosa
''Xanthoparmelia scabrosa'', jocularly known as sexy footpath lichen or sexy pavement lichen, is a foliose lichen in the family Parmeliaceae. It tolerates a very wide range of substrata, predominantly rock but also tree bark, roofing tiles, glass, and in wetter areas bitumen paths and roads. Taxonomy and naming The lichen was first formally described under the name ''Parmelia scabrosa'' in 1847 by botanist Thomas Taylor. The type was collected by botanist James Drummond near Swan River in Western Australia. It became known as a species of '' Xanthoparmelia'' in 1974 when Mason Hale promoted that subgenus of ''Parmelia'' to generic status. The lichen was dubbed 'sexy footpath lichen' in a talk for the Auckland Botanical Society by Allison Knight. The name was popularised by Peter de Lange as 'sexy pavement lichen'. Description ''Xanthoparmelia scabrosa'' has a thallus that is foliose (leafy in appearance). The upper surface is yellow-green, while the lower surface is ...
