Geoglossum Barlae
''Geoglossum'' is a genus of fungi in the family Geoglossaceae. They are commonly called earth tongues. The type species is '' Geoglossum glabrum''. ''Geoglossum'' species are distinguished from the related genus '' Trichoglossum'' by the lack of setae on the spore bearing surface. ''Geoglossum'' species are characterized by dark, club-shaped, terrestrial ascocarps with a fertile hymenium continuing downward from the apex of the ascocarp along the stipe, eventually intergrading with a sterile stipe. The ascospores of ''Geoglossum'' range from translucent to dark brown, and are fusiform, and multiseptate. Identification of species is based on the gross morphology of the ascocarp, color and septation of the ascospores, and shape and ornamentation of the paraphyses. Taxonomy ''Geoglossum'' was described by Christian Hendrik Persoon in 1794, who created the genus to accommodate ''Clavaria ophioglossoides'' L. and three other species: ''Geoglossum hirsutum'' (now '' Trichoglossu ...

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] |
Hyaline
A hyaline substance is one with a glassy appearance. The word is derived from , and . Histopathology Hyaline cartilage is named after its glassy appearance on fresh gross pathology. On light microscopy of H&E stained slides, the extracellular matrix of hyaline cartilage looks homogeneously pink, and the term "hyaline" is used to describe similarly homogeneously pink material besides the cartilage. Hyaline material is usually acellular and proteinaceous. For example, arterial hyaline is seen in aging, high blood pressure, diabetes mellitus and in association with some drugs (e.g. calcineurin inhibitors). It is bright pink with PAS staining. Ichthyology and entomology In ichthyology and entomology Entomology (from Ancient Greek ἔντομον (''éntomon''), meaning "insect", and -logy from λόγος (''lógos''), meaning "study") is the branch of zoology that focuses on insects. Those who study entomology are known as entomologists. In ..., ''hyaline'' denotes a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Curtis Gates Lloyd
Curtis Gates Lloyd (July 17, 1859 – November 11, 1926) was an American mycologist known for both his research on the gasteroid and polypore fungi, as well as his controversial views on naming conventions in taxonomy. He had a herbarium with about 60,000 fungal specimens, and described over a thousand new species of fungi. Along with his two brothers John Uri Lloyd and Nelson Ashley Lloyd, he founded the Lloyd Library and Museum in Cincinnati. Early life Born on July 17, 1859, in Florence, Kentucky, Curtis Gates Lloyd was the third son of Nelson Marvin and Sophia Webster Lloyd. He and his family moved to Crittenden, Kentucky, in 1867, where Lloyd lived until he was 18. He moved to Cincinnati and was employed as an apprentice in Johnson's pharmacy. This was where he met Dr. John King, physician and editor of the ''American Dispensatory''; the close friendship they formed helped to fuel Lloyd's interest in botany. Lloyd earned his pharmacy certificate while working at the pha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

George Edward Massee
George Edward Massee (20 December 1845 – 16 February 1917) was an English mycologist, plant pathologist, and botanist. Background and education George Massee was born in Scampston, East Riding of Yorkshire, the son of a farmer. He was educated at York School of Art and claimed to have attended Downing College, Cambridge, though no record exists of him in the University or College Records. South America and the Foreign Legion Massee had an early interest in natural history, publishing an article on British woodpeckers at the age of 16 and compiling a portfolio of botanical paintings. Through the influence of Richard Spruce, a family relative, he was able to travel on a botanical expedition to Panama and Ecuador, where, despite considerable hardships, he collected orchids and other plants. On his return, Massee joined the French Foreign Legion, hoping to see combat in the Franco-Prussian War, but, the war being almost over, he was prevailed upon to return home to the farm ...

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] |
Sanctioned Name
In mycology, a sanctioned name is a name that was adopted (but not necessarily coined) in certain works of Christiaan Hendrik Persoon or Elias Magnus Fries, which are considered major points in fungal taxonomy. Definition and effects Sanctioned names are those, regardless of their authorship, that were used by Persoon in his '' Synopsis Methodica Fungorum'' (1801) for rusts, smuts and gasteromycetes, and in Fries's ''Systema Mycologicum'' (three volumes, published 1821–1832) and '' Elenchus fungorum'' for all other fungi. A sanctioned name, as defined under article 15 of the ''International Code of Nomenclature for algae, fungi, and plants'' (previously, the ''International Code of Botanical Nomenclature'') is automatically treated as if conserved against all earlier synonyms or homonyms. It can still, however, be conserved or rejected normally. History Because of the imprecision associated with assigning starting dates for fungi sanctioned in Fries' three ''Systema'' vo ...

Microglossum Viride
''Microglossum viride'' is a species of fungus A fungus (: fungi , , , or ; or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and mold (fungus), molds, as well as the more familiar mushrooms. These organisms are classified as one ... in the family (biology), family Leotiaceae. They are commonly called green earth tongues. Etymology The word ''Microglossum'' comes from the Ancient Greek, Greek words mikrós + glōssa, and literally means "small tongue". The species epithet, ''viride,'' comes from the Latin viridis for "green." History ''Microglossum viride'' was described by Christiaan Hendrik Persoon in 1797 as ''Geoglossum viride''. In 1879 it was moved into the genus ''Microglossum''. Similar species Collections of green ''Microglossum'' with scaly stipe had been commonly called ''M. viride''. In 2014 morphological and molecular data revealed another taxon hidden under this name that was segregated and describ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trichoglossum Hirsutum
''Trichoglossum hirsutum'' is a species of fungus in the family Geoglossaceae. In the UK, it has been given the recommended English name of hairy earthtongue. In North America it is known variously as velvety black earth tongue, velvety earth tongue, shaggy earth tongue, or black earth tongue. DNA evidence suggests the hairy earthtongue may be a species complex. Taxonomy The species was first described by mycologist Christian Hendrik Persoon in 1794 as ''Geoglossum hirsutum''. In 1907 Jean Louis Émile Boudier transferred the species to his new genus '' Trichoglossum'', of which it is the type. Initial molecular research, based on cladistic analysis of DNA sequences, indicates that ''Trichoglossum hirsutum'' sensu lato comprises at least three separate taxa in Europe and North America, though these may not be morphologically distinguishable. At least one of these cryptic species occurs in both continents. Description Ascocarps are club-shaped, up to tall, black to dark brown, ...

Paraphyses
Paraphyses are erect sterile filament-like support structures occurring among the reproductive apparatuses of fungi, ferns, bryophytes and some thallophytes. The singular form of the word is paraphysis. In certain fungi, they are part of the fertile spore-bearing layer. More specifically, paraphyses are sterile filamentous hyphal end cells composing part of the hymenium of Ascomycota and Basidiomycota interspersed among either the asci or basidia respectively, and not sufficiently differentiated to be called cystidia A cystidium (: cystidia) is a relatively large cell found on the sporocarp of a basidiomycete (for example, on the surface of a mushroom gill), often between clusters of basidia. Since cystidia have highly varied and distinct shapes that are o ..., which are specialized, swollen, often protruding cells. The tips of paraphyses may contain the pigments which colour the hymenium. In ferns and mosses, they are filament-like structures that are found on sporangi ...
