Hypotrachyna Osseoalba
''Hypotrachyna osseoalba'', commonly known as the grainy loop lichen, is a species of foliose lichen in the family Parmeliaceae. It is widely distributed in subtropical and temperate areas of the world. Characteristic features of the lichen include the pustules in its cortex, the somewhat linear shape of the lobes comprising the thallus, and the branched rhizines (holdfasts on the thallus underside). Taxonomy It was first scientifically described by Finnish lichenologist Edvard Vainio in 1921, as ''Parmelia osseoalba''. Yun Sil Park and Mason Hale transferred it to the genus ''Hypotrachyna'' in 1989. The taxon ''Parmelia formosana'', described by Alexander Zahlbruckner in 1934, later became ''Hypotrachyna formosana'' after Hale transferred it to ''Hypotrachyna'' in 1975. When Hale was later working on a monograph of genus ''Xanthoparmelia'', he studied the type material of Vainio's ''Parmelia osseoalba'', and determined that it was identical both chemically and morphologicall ...

Morphology (biology)
Morphology is a branch of biology dealing with the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance (shape, structure, colour, pattern, size), i.e. external morphology (or eidonomy), as well as the form and structure of the internal parts like bones and organs, i.e. internal morphology (or anatomy). This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of gross structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Friedrich Burdach ...

Eastern United States
The Eastern United States, commonly referred to as the American East, Eastern America, or simply the East, is the region of the United States to the east of the Mississippi River. In some cases the term may refer to a smaller area or the East Coast plus Illinois, Wisconsin, Indiana, Mississippi, and their border states. In 2011, the 26 states east of the Mississippi (in addition to Washington, D.C. but not including the small portions of Louisiana and Minnesota east of the river) had an estimated population of 179,948,346 or 58.28% of the total U.S. population of 331,745,358 (excluding Puerto Rico). New England New England is a region of the United States located in the northeastern corner of the country, bounded by the Atlantic Ocean, Canada and the state of New York, consisting of the modern states of Maine, New Hampshire, Vermont, Massachusetts, Rhode Island, and Connecticut.

Lichexanthone
Lichexanthone is an organic compound in the structural class of chemicals known as xanthones. Lichexanthone was first isolated and identified by Japanese chemists from a species of leafy lichen in the 1940s. The compound is known to occur in many lichens, and it is important in the taxonomy of species in several genera, such as ''Pertusaria'' and ''Pyxine''. More than a dozen lichen species have a variation of the word lichexanthone incorporated as part of their binomial name. The presence of lichexanthone in lichens causes them to fluoresce a greenish-yellow colour under long-wavelength UV light; this feature is used to help identify some species. Lichexanthone is also found in several plants (many are from the families Annonaceae and Rutaceae), and some species of fungi that do not form lichens. In lichens, the biosynthesis of lichexanthone occurs through a set of enzymatic reactions that start with the molecule acetyl-CoA and sequentially add successive units, forming a longe ...
