Canoparmelia Nashii
''Canoparmelia'' is a genus of lichen-forming fungi in the family Parmeliaceae. The widespread genus contains about 35 species. ''Canoparmelia'', a segregate of the parmelioid lichen genus ''Pseudoparmelia'', was circumscribed by John Elix and Mason Hale in 1986. Description ''Canoparmelia'' lichens have grey or rarely yellow-green thalli containing the secondary chemicals atranorin and chloroatranorin, or rarely usnic acid, in the cortex. The thallus is made of more or less rotund lobes that are 3.0–5.0 mm wide and lack cilia; the medulla is white. The underside of the thallus is black or brown with naked brown margins and simple rhizines of the same colour. ''Canoparmelia'' produces small ellipsoid ascospores that measure 10–14 by 6–8 μm. The conidia are fusiform (spindle-shaped) or bifusiform, measuring 7–10 μm long.

John Alan Elix
John Alan (Jack) Elix (born 1941) emeritus professor in chemistry at the Australian National University, is an organic chemist who has contributed in many fields: lichenology, lichen chemotaxonomy, plant physiology and biodiversity and natural product chemistry. He has authored 2282 species names, and 67 genera in the field of mycology. Education His first degree, B.Sc., and his Ph.D were both in organic chemistry from the University of Adelaide. This was followed by post-doctoral years at the University of Cambridge and then a D.Sc. in natural products chemistry from the Australian National University. Career Elix spent a post doctoral year in 1966 at Cambridge, returning to Australia in 1967 to a lectureship in chemistry at the ANU. He retired as professor of chemistry in 2002, becoming professor emeritus. By 1975 he had already published several papers on the organic chemistry of lichens, and ultimately leading to work on the evolution, taxonomy and phylogeny of liche ...

Medulla (lichenology)
The medulla is a horizontal layer within a lichen thallus. It is a loosely arranged layer of interlaced hyphae below the upper cortex and photobiont A lichen ( , ) is a composite organism that arises from algae or cyanobacteria living among filaments of multiple fungi species in a mutualistic relationship.Galloway, D.J. (1992). Flora of Australia - ''Lichen Glossary'' The medulla generally has a cottony appearance. It is the widest layer of a heteromerous lichen thallus.

Canoparmelia Albomaculata
''Canoparmelia albomaculata'' is a species of lichen in the family Parmeliaceae.Marcelli, M. P., and Celio Henrique Ribeiro. "Twenty-one new species of Parmeliaceae (lichenized fungi) from southeastern Brazil." Mitt. Inst. Allg. Bot. Hamburg 30.32 (2002): 125–155 (see p. 129). This species is very similar to the apostulate ''Canoparmelia caroliniana'', showing the same colour, size and reticulate maculae. ''C. caroliniana'', however, has true isidia. Big coralloid pustules that in some cases become sorediate are a characteristic feature for ''C. albomaculata''. Description It possesses a whitish-green thallus that measures wide, its adnate lobes measuring between wide. Its surface is smooth and irregularly cracked. The species' ramification is irregularly dichotomous, with rounded apices, an oval axillary sinus, and a black-lined margin with no cilia. It shows no lacinules while possessing laminal maculae. Its pustulae are found as marginal and submarginal, it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Conidium
A conidium ( ; ), sometimes termed an asexual chlamydospore or chlamydoconidium (), is an asexual, non-motile spore of a fungus. The word ''conidium'' comes from the Ancient Greek word for dust, ('). They are also called mitospores due to the way they are generated through the cellular process of mitosis. The two new haploid cells are genetically identical to the haploid parent, and can develop into new organisms if conditions are favorable, and serve in biological dispersal. Asexual reproduction in ascomycetes (the phylum Ascomycota) is by the formation of conidia, which are borne on specialized stalks called conidiophores. The morphology of these specialized conidiophores is often distinctive between species and, before the development of molecular techniques at the end of the 20th century, was widely used for identification of (''e.g.'' ''Metarhizium'') species. The terms microconidia and macroconidia are sometimes used. Conidiogenesis There are two main types of co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Micrometre
The micrometre ( international spelling as used by the International Bureau of Weights and Measures; SI symbol: μm) or micrometer (American spelling), also commonly known as a micron, is a unit of length in the International System of Units (SI) equalling (SI standard prefix "micro-" = ); that is, one millionth of a metre (or one thousandth of a millimetre, , or about ). The nearest smaller common SI unit is the nanometre, equivalent to one thousandth of a micrometre, one millionth of a millimetre or one billionth of a metre (). The micrometre is a common unit of measurement for wavelengths of infrared radiation as well as sizes of biological cells and bacteria, and for grading wool by the diameter of the fibres. The width of a single human hair ranges from approximately 20 to . The longest human chromosome, chromosome 1, is approximately in length. Examples Between 1 μm and 10 μm: * 1–10 μm – length of a typical bacterium * 3–8 μm – width of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
