Ramaria Invalii
The genus ''Ramaria'' comprises approximately 200 species of coral fungi. Several, such as '' Ramaria flava'', are edible and picked in Europe, though they are easily confused with several mildly poisonous species capable of causing nausea, vomiting, and diarrhea; these include '' R. formosa'' and '' R. pallida''. Three ''Ramaria'' species have been demonstrated to contain a very unusual organoarsenic compound homoarsenocholine. Etymology The genus name is derived from Latin ''rāmus'' meaning ''branch''. Description Basidiocarps may range in color from bright yellow, red, pink, or orange, to purple, white, and shades of tan. Color changes after bruising occur in some species. The spores of ''Ramaria'' species are yellow-brown to rusty-brown in mass deposit and range from smooth to warted to echinulate or striate. Spore size may vary considerably, and ornamentation, when present, is cyanophilous. Classification Hjomsköld was the first to introduce the name ''Ramaria'' in 179 ...

Elias Magnus Fries
Elias Magnus Fries (15 August 1794 – 8 February 1878) was a Swedish mycologist and botanist. He is sometimes called the Mycology, "Linnaeus of Mycology". In his works he described and assigned botanical names to hundreds of fungus and lichen species, many of which remain authoritative today. Career Fries was born at Femsjö (Hylte Municipality), Småland, the son of the pastor there. He attended school in Växjö. He acquired an extensive knowledge of flowering plants from his father. In 1811 Fries entered Lund University where he studied under Carl Adolph Agardh and Anders Jahan Retzius. He obtained his doctorate in 1814. In the same year he was appointed an associate professorship in botany. Fries edited several exsiccata series, the first starting in 1818 under the title ''Lichenes Sveciae exsiccati, curante Elia Fries'' and the last together with Franz Joseph Lagger under the title ''Hieracia europaea exsiccata''. He was elected a member of the Royal Swedish Academ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Christian Hendrik Persoon
Christiaan Hendrik Persoon (31 December 1761 – 16 November 1836) was a Cape Colony mycologist who is recognized as one of the founders of mycology, mycological Taxonomy (biology), taxonomy. Early life Persoon was born in Cape Colony at the Cape of Good Hope, the third child of an immigrant Pomeranian father, Christiaan Daniel Persoon, and Netherlands, Dutch mother, Wilhelmina Elizabeth Groenwald. His mother died soon after he was born. In 1775, at the age of thirteen, he was sent to Europe for his education. His father died a year later in 1776. Education Initially a student of theology at University of Halle-Wittenberg, Halle, Persoon switched his studies to medicine, which he pursued in Leiden and then Göttingen. He received a doctorate from the German National Academy of Sciences Leopoldina, Deutsche Akademie der Naturforscher in Erlangen 1799. Later years He moved to Paris by 1803, where he spent the rest of his life, renting the upper floor of a house in a poor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ramaria Acrisiccescens
''Ramaria acrisiccescens'', commonly known as the blah coral, is a coral fungus in the family Gomphaceae. It is found in the forests of northwestern North America. Taxonomy The species was first described scientifically by mycologists Currie Marr and Daniel Stuntz in their 1974 monograph, "''Ramaria'' of western Washington". The holotype was collected in 1966 about south of Elbe, Washington. It is classified in the subgenus ''Laeticolora''. It is commonly known as the "blah coral". Description The whitish fruit bodies are large, generally taller than wide, measuring tall by wide. The stipe, which is often deeply buried, is slender and tapered, measuring by wide. Fruit bodies consist of elongated branches with roughly parallel arrangements. Each branch itself branches up to 9 times in a dichotomous fashion; each of these branches is slender, typically 1–12 mm in diameter. The branch tips are usually rounded. The context has a fleshy or fibrous consistency, but it b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monophyletic
In biological cladistics for the classification of organisms, monophyly is the condition of a taxonomic grouping being a clade – that is, a grouping of organisms which meets these criteria: # the grouping contains its own most recent common ancestor (or more precisely an ancestral population), i.e. excludes non-descendants of that common ancestor # the grouping contains all the descendants of that common ancestor, without exception Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic'' grouping meets 1. but not 2., thus consisting of the descendants of a common ancestor, excepting one or more monophyletic subgroups. A '' polyphyletic'' grouping meets neither criterion, and instead serves to characterize convergent relationships of biological features rather than genetic relationships – for example, night-active primates, fruit trees, or aquatic insects. As such, these characteristic features of a polyphyletic grouping ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
