Dennisiomyces
''Dennisiomyces'' is a genus of fungi in the family Tricholomataceae. Described by mycologist Rolf Singer in 1955, the genus contains five species found in South America. The genus name of ''Dennisiomyces'' is in honour of Richard William George Dennis (1910 - 2003), British botanist (mycology) and plant pathologist.

List Of Tricholomataceae Genera
The Tricholomataceae are a family of fungi in the order Agaricales. A 2008 estimate placed 78 genera and 1020 species in the family. Subsequent molecular research, based on cladistic analysis of DNA sequences, has however found that this wide interpretation of the Tricholomataceae renders the family polyphyletic and is no longer tenable. In 2014, Sánchez-García and colleagues proposed a revised classification of the Tricholomataceae with just seven genera: '' Leucopaxillus'', ''Tricholoma'', ''Dennisiomyces'', '' Porpoloma'', and the newly circumscribed genera '' Corneriella'', '' Pogonoloma'' (now moved to the Pseudoclitocybaceae), and '' Pseudotricholoma''. Of the genera formerly placed in the Tricholomataceae, ''Amparoina'' is considered a synonym of ''Mycena''; '' Callistosporium'' (with '' Pleurocollybia'' as a synonym) and '' Macrocybe'' have been moved to the Callistosporiaceae '' Catathelasma'' has been moved to the Biannulariaceae; '' Phyllotopsis'' and '' Tricholo ...

Tricholomataceae
The Tricholomataceae are a large family of fungi within the order Agaricales. Originally a classic "wastebasket taxon", the family included any white-, yellow-, or pink-spored genera in the Agaricales not already classified as belonging to e.g. the Amanitaceae, Lepiotaceae, Hygrophoraceae, Pluteaceae, or Entolomataceae. The name derives from the Greek ''trichos'' (τριχος) meaning hair and ''loma'' (λωμα) meaning fringe or border, although not all members display this feature. The name "Tricholomataceae" is seen as having validity in describing '' Tricholoma'' and other genera that form part of a monophyletic family including ''Tricholoma''. To that end, the International Botanical Congress has voted on two occasions (1988 and 2006) to conserve the name "Tricholomataceae" against competing names. This decision does not invalidate the use of segregate families from the Tricholomataceae, but simply validates the continued use of Tricholomataceae. Taxonomy Molecular ph ...

Richard William George Dennis
Richard William George Dennis, PhD (13 July 1910 – 7 June 2003), was an English mycologist and plant pathologist. Background and education Dennis was born in Thornbury, Gloucestershire, the son of a schoolmaster. He was educated at Thornbury Grammar School and Bristol University, where he studied geology and botany, writing a thesis on canker disease of willow. In 1930, he obtained a post in the Plant Husbandry Department of the West of Scotland Agricultural College in Glasgow, where he studied diseases of oats. This became the subject of his PhD from the University of Glasgow in 1934. Career and travels In 1939, Dr Dennis secured a post as Assistant Plant Pathologist at the Department of Agriculture, Edinburgh. He returned to England in 1944 and became assistant to Elsie Maud Wakefield, head of mycology at the Royal Botanic Gardens, Kew. On her retirement in 1951, R.W.G. Dennis took over her position and remained at Kew till his own retirement in 1975. His early ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Agaricales Genera
This is a list of fungal genus, genera in the order (biology), order Agaricales. The list follows Kalichman, Kirk & Matheny (2020), with more recent additions and amendments, as noted. The number of species in each family is taken from Catalogue of Life (2023) and is subject to change as new research is published. Many genera are not as yet assigned to a family and are listed under "incertae sedis".

Plant Pathologist
Plant pathology or phytopathology is the scientific study of plant diseases caused by pathogens (infectious organisms) and environmental conditions (physiological factors). Plant pathology involves the study of pathogen identification, disease etiology, disease cycles, economic impact, plant disease epidemiology, plant disease resistance, how plant diseases affect humans and animals, pathosystem genetics, and management of plant diseases. Plant pathogenicity Plant pathogens, organisms that cause infectious plant diseases, include fungi, oomycetes, bacteria, viruses, viroids, virus-like organisms, phytoplasmas, protozoa, nematodes and parasitic plants. In most plant pathosystems, virulence depends on hydrolases and enzymes that degrade the cell wall. The vast majority of these act on pectins (for example, pectinesterase, pectate lyase, and pectinases). For microbes, the cell wall polysaccharides are both a food source and a barrier to be overcome. Many pathogens grow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fungi
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 of the kingdom (biology)#Six kingdoms (1998), traditional eukaryotic kingdoms, along with Animalia, Plantae, and either Protista or Protozoa and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of motility, mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
