Mountain Cobblestone Lichen
''Acarospora elevata'', the mountain cobblestone lichen, is a shiny dark reddish brown to dark brown verrucose to aereolate crustose lichen that grows up to wide on granite in central and southern California to Baja California, and high elevations in the Rocky Mountains.Field Guide to California Lichens, Stephen Sharnoff, Yale University Press, 2014, Lichen Flora of the Greater Sonoran Desert Region. Vol 3., Nash, T.H., Ryan, B.D., Gries, C., Bugartz, F., (eds.) 2001/ref> It is usually only found above because it is eaten by red mites at lower elevations. In the Californias, it is mostly found at high elevations (hence ''"elevata"''), but sometimes in coastal locations where it is less glossy. It grows in full sun, mostly on hard granite, but sometimes other igneous or carbonate rock, from in elevation. It may start by growing on members of the genus ''Aspicilia'', or other such pioneer species on hard rocks. There are typically between zero and four apothecia on each ar ...

Verrucose
The following is a glossary of terms used in the description of lichens, composite organisms that arise from algae or cyanobacteria living among filaments of multiple fungus species in a mutualistic relationship. Until the end of the 18th century, only a couple of lichen-specific terms had been proposed. Johann Dillenius introduced ' in 1742 to describe the cup-shaped structures associated with genus ''Cladonia'', while in 1794 Michel Adanson used ' for the furrowed fruitbodies of the genus '' Graphis''. Erik Acharius, the "father of lichenology", conceived many new terms to describe lichen structures in several of his seminal publications in the early 1800s. Examples include , , , , , , and . In 1825, Friedrich Wallroth published the first of his multi-volume work ''Naturgeschichte der Flechten'' ("Natural History of Lichens"), in which he proposed an alternative terminology based largely on roots from the Greek language. His work, presented as an alternative to that of Acha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lichens Described In 1929
A lichen ( , ) is a composite organism that arises from algae or cyanobacteria living among filaments of multiple fungi species in a mutualistic relationship.Introduction to Lichens – An Alliance between Kingdoms . University of California Museum of Paleontology. Lichens have properties different from those of their component organisms. They come in many colors, sizes, and forms and are sometimes plant-like, but are not s. They may have tiny, leafless branches (); flat leaf-like structures ( [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
