Lecanora Muralis
''Lecanora muralis'' ''(Protoparmeliopsis muralis)'' is a waxy looking, pale yellowish green crustose lichen, crustose lichen that usually grows in rosette (botany), rosettes radiating from a center (placoidiod, placodioid) filled with disc-like yellowish-tan fruiting bodies (apothecia).Field Guide to California Lichens, Stephen Sharnoff, Yale University Press, 2014, , page 279 It grows all over the world.Lichen Flora of the Greater Sonoran Desert Region.

The fruiting body parts have rims of tissue similar to that of the main nonfruiting body (thallus), which is called being lecanorine. It is paler and greener than ''Lecanora mellea, L. mellea'', and more yellow than ''Lecanora sierra, L. sierrae''.

Fungi Described In 1855
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, Protozoa, and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''true fungi' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Verrucariales
Verrucariales is an order of ascomycetous fungi within the subclass Chaetothyriomycetidae of the class Eurotiomycetes. Although most of the Verrucariales are lichenised, the family Sarcopyreniaceae consists of 11 species of lichenicolous (lichen-dwelling) fungi. Phylogenomic analysis suggests that the divergence between the lichenized Verrucariales and nonlichenized Chaetothyriales The Chaetothyriales are an order of ascomycetous fungi in the class Eurotiomycetes and within the subclass Chaetothyriomycetidae.

Rusavskia Elegans
''Rusavskia elegans'' (formerly ''Xanthoria elegans''), commonly known as the elegant sunburst lichen, is a lichenized species of fungus in the genus ''Rusavskia'', family Teloschistaceae. Recognized by its bright orange or red pigmentation, this species grows on rocks, often near bird or rodent perches. It has a circumpolar and alpine distribution. It was one of the first lichens to be used for the rock-face dating method known as lichenometry. Taxonomy ''Rusavskia elegans'' was first formally described by Johann Heinrich Friedrich Link as ''Lichen elegans'' in 1791, and transferred to the genus ''Xanthoria'' by Theodor Magnus Fries (son of Elias Magnus Fries) in 1860. In 2003, Sergey Kondratyuk and Ingvar Kärnefelt transferred the taxon to their newly circumscribed genus ''Rusavskia'', in which it is the type species. Although the new genus was not initially widely accepted, subsequent molecular phylogenetic studies showed the validity of the new classification. Description ...

Rhizocarpon Geographicum
''Rhizocarpon geographicum'' (the map lichen) is a species of lichen, which grows on rocks in mountainous areas of low air pollution. Each lichen is a flat patch bordered by a black line of fungal hyphae. These patches grow adjacent to each other, leading to the appearance of a map or a patchwork field. When circular, or roughly circular, the diameter of this lichen species has been widely used to help determining the relative age of deposits, e.g. moraine systems, thus revealing evidence of glacial advances. The process is termed lichenometry. This technique is generally attributed to the work of Roland Beschel in the Alps. Lichenometry is based on the assumption that the largest lichen growing on a rock is the oldest individual. Generally, the five largest lichen thalli diameters are taken, although several statistical methods have been used. If the growth rate is known, the maximum lichen size will give a minimum age for when this rock was deposited. The growth rate curve, a g ...

Lecidea Obluridata
''Lecidea'' is a genus of crustose lichens with a carbon black ring or outer margin (exciple) around the fruiting body disc (apothecium), usually (or always) found growing on ( saxicolous) or in (endolithic) rock.Field Guide to California Lichens, Stephen Sharnoff, Yale University Press, 2014, Lichens that have such a black exciple are called lecideine, meaning "like ''Lecidea'', even if they are not in this genus.

Lecanora Polytropa
''Lecanora polytropa'', commonly known as the granite-speck rim lichen, is a species of saxicolous lichen in the family Parmeliaceae. A small, inconspicuous species that grows in the cracks of rock surfaces, it has a cosmopolitan distribution and has been recorded on all continents, including Antarctica. Taxonomy It was originally described by German botanist Jakob Friedrich Ehrhart in 1796 as a species of ''Verrucaria''. Gottlob Ludwig Rabenhorst transferred it to the genus ''Lecanora'' in 1845. It is commonly known as the granite-speck rim lichen. Description ''Lecanora polytropa'' has a scanty thallus, which sometimes resembles tiny pale yellowish areoles. The tiny, flat apothecia typically measure 0.3–0.9 mm in diameter and may be scattered or clustered together. They have a waxy texture and are yellow to pale orange, lacking pruina. The margins of the apothecia are smooth, not prominent, and tend to be lighter in colour than the central disc. Ascospores are el ...
