Niebla Juncosa
''Niebla juncosa'' is a fruticose lichen that grows on rock, stony soil and sand along the Pacific Coast of Baja California from Punta Banda to Morro Santo Dominogo.Spjut, R. W. 1996. ''Niebla'' and ''Vermilacinia'' (Ramalinaceae) from California and Baja California. Sida Bot. Misc. 14 The epithet, ''juncosa'' is in reference to the thallus divided into rush-like branches, the stems of the flowering plant genus ''Juncus''. Distinguishing features ''Niebla juncosa'' is distinguished by the thallus divided into sublinear subterete branches with a common attachment base (or holdfast); the primary branches generally creeping or ascending to erect, occasionally dividing into equal secondary branches and developing numerous similar branchlets along the upper side of a main branch (var. ''juncosa'') or branchlets spreading in all directions (var. ''spinulifera''), the branch margins not alternating with the cortical ridges; the whole thallus to 10 cm high and 15 cm in diam ...

Fruticose Lichen
A fruticose lichen is a form of lichen fungi that is characterized by a coral-like shrubby or bushy growth structure. It is formed from a symbiotic relationship of a photobiont such as green algae or less commonly cyanobacteria and one, two or more mycobionts. Fruticose lichens are not a monophyletic and holophyletic lineage, but is a form encountered in many classes. Fruticose lichens have a complex vegetation structure, and are characterized by an ascending, bushy or pendulous appearance. As with other lichens, many fruticose lichens can endure high degrees of desiccation. They grow slowly and often occur in habitats such as on tree barks, on rock surfaces and on soils in the Arctic and mountain regions. Characteristics Fruticose lichens are lichens composed of a shrubby or bushy thallus and a holdfast. The thallus is the vegetative body of a lichen that does not have true leaves, stems, or roots. The thallus colour is affected by the algae in the lichen, compounds created by t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lichens Of North America
Irwin M. Brodo (born 1935) is an emeritus scientist at the Canadian Museum of Nature, in Ottawa, Ontario, Canada. He is an authority on the identification and biology of lichens. Irwin Brodo was honored in 1994 with an Acharius Medal presented to him by the International Association for Lichenology. Brodo did his undergraduate studies at Columbia University, and received a master's degree from Cornell University. He earned a Ph.D. in lichenology under the supervision of Henry Imshaug at Michigan State University. He later went on to teach at Université Laval and the University of Alaska, and he also supervised master's students at the University of Ottawa and Carleton University. Brodo's list of publications includes 75 research papers, 8 popular articles, 22 reviews and 6 editorials and obituaries. In 1993, Brodie was awarded the Mary E.

Spinule
Spinules are small spines or thorns (vertebral columns) that are part of biological and manmade structures. The word originates from the Latin word and is often used in botany and zoology. The presence or absence of spinules, and their shape, can differentiate species and is used to describe and distinguish anatomical features. The development of spinules in the eye may be affected by dopamine, circadian rhythms, and exposure to light or dark environments, according to a studies of controlling mechanisms. liquid-crystal displays (LCDs) can employ an anisotropic Anisotropy () is the property of a material which allows it to change or assume different properties in different directions, as opposed to isotropy.
