Mycena Mariae
''Mycena mariae'' is a species of fungus in the family Mycenaceae. The species was scientifically described by G. Stevenson and effectively published in 1964. Description ''Mycena mariae'' mushrooms are distinguished by their dark red pigment and large, elongate spores. ''M. mariae'' has tissues are more pseudoamyloid than those of similar species such as '' Mycena morris-jonesii''. The cap of the mushroom is small, pink to red, with gills underneath. The stipe is hollow and darker at the base. Habitat and distribution ''Mycena mariae'' mushrooms are typically found in litter under the canopy of a mixed podocarp Podocarpaceae is a large family of mainly southern hemisphere conifers, known in English as podocarps, comprising about 156 species of evergreen trees and shrubs.James E.

Greta Stevenson
Greta Barbara Stevenson (10 June 1911 – 18 December 1990) was a New Zealand botanist and mycologist. She described many new species of Agaricales (gilled mushrooms). Background and education Stevenson was born in Auckland, New Zealand, the oldest of four children of William Stevenson and his wife Grace Mary Scott. William was the managing director of the canned food manufacture Irvine and Stevenson. The Stevenson family moved to Dunedin in 1914, and Greta attended Columba College from 1925 to 1928. She later went on to the University of Otago in 1929, from which she graduated with a BSc in 1932, and then an MSc in botany with first-class honors in 1933. Her thesis was about the life history of the rare parasitic ''Korthalsella''. After graduating she moved to London to attend the Imperial College of Science and Technology, where she completed a PhD in mycology and plant pathology. She married Edgar Cone in 1936, a research student in chemical engineering, with whom she had t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mycenaceae
The Mycenaceae are a family of fungi in the order Agaricales. According to the ''Dictionary of the Fungi'' (10th edition, 2008), the family contains 10 genera and 705 species. This is one of several families that were separated from the Tricholomataceae as a result of phylogenetic analyses. Taxa in the Mycenaceae are saprobic, have a cosmopolitan distribution, and are found in almost all ecological zones. The family was circumscribed by Caspar van Overeem in 1926. The extinct genus '' Protomycena'', described from Burdigalian age Dominican amber found on the island of Hispaniola is one of four known agaric genera in the fossil record. Phylogeny A large-scale phylogenetic analysis study of the Agaricales published by a consortium of mycologists in 2002 adopted the name Mycenaceae for a strongly supported clade In biology, a clade (), also known as a Monophyly, monophyletic group or natural group, is a group of organisms that is composed of a common ancestor and all of i ...

Pseudoamyloid
In mycology a tissue or feature is said to be amyloid if it has a positive amyloid reaction when subjected to a crude chemical test using iodine as an ingredient of either Melzer's reagent or Lugol's solution, producing a blue to blue-black staining. The term "amyloid" is derived from the Latin ''amyloideus'' ("starch-like"). It refers to the fact that starch gives a similar reaction, also called an amyloid reaction. The test can be on microscopic features, such as spore walls or hyphae, hyphal walls, or the apical apparatus or entire ascus wall of an ascus, or be a macroscopic reaction on tissue where a drop of the reagent is applied. Negative reactions, called inamyloid or nonamyloid, are for structures that remain pale yellow-brown or clear. A reaction producing a deep reddish to reddish-brown staining is either termed a dextrinoid reaction (pseudoamyloid is a synonym) or a hemiamyloid reaction. Melzer's reagent reactions Hemiamyloidity Hemiamyloidity in mycology refers to a s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mycena Morris-jonesii
''Mycena'' is a genus of about 500 species of fungi. Rarely more than a few centimeters in width, the mushrooms are characterized by a small conical or bell-shaped cap and a thin fragile stem. Most are grey or brown, but a few species have brighter colours. Most have a translucent and striate cap, which rarely has an incurved margin. The gills are attached and usually have cystidia. Some species, like '' M. haematopus'', exude a latex when the stem is broken, and many species have a chlorine or radish-like odour. They produce a white spore print. The species are saprotrophic. Their edibility varies, with some members containing toxins. Taxonomy ''Mycena'' is a rich genus, considered one of the most abundant genera of mushrooms within the Agaricales and with species distributed across the world. Alexander Smith's 1947 ''Mycena'' monograph identified 232 species; the genus is now known to include about 500 species worldwide. Maas Geesteranus divided the genus into 38 se ...

Podocarp
Podocarpaceae is a large family of mainly southern hemisphere conifers, known in English as podocarps, comprising about 156 species of evergreen trees and shrubs.James E. Eckenwalder. 2009. ''Conifers of the World''. Portland, Oregon: Timber Press. . It contains 20 genera if '' Phyllocladus'' is included and '' Manoao'' and '' Sundacarpus'' are recognized. The family achieved its maximum diversity in the Cenozoic, making the Podocarpaceae family one of the most diverse in the southern hemisphere. The family is a classic member of the Antarctic flora, with its main centres of diversity in Australasia, particularly New Caledonia, Tasmania, and New Zealand, and to a slightly lesser extent Malesia and South America (primarily in the Andes Mountains). Several genera extend north of the equator into Indochina and the Philippines. ''Podocarpus'' reaches as far north as southern Japan and southern China in Asia, and Mexico in the Americas, and '' Nageia'' into southern China and souther ...
