Features
Macroscopic characteristics
The hat measures 1.5 to 5, rarely to 8 cm in diameter is initially conical, later convex to spread. He usually has a produced by a concentric recess blunt hump and partly a highly curved edge. Its edge is usually grooved translucent, the surface is smooth and shiny with moisture changes their appearance ( Hygrophanität ). Mingled The coloring is typically pale purple, but extremely variable with some all sorts of pink tones, yellow - whitish, reddish, flesh-colored, violet, bluish- gray ... The blades are lighter than the hat surface, wide, connected wires at the base, stand and are bulged grown on a stick. Their cutting edges are bulging shape and weak notched. The stem is 4-7 inches long and 2-8 mm thick, is fragile and finely designed straight-grained, plump young, then stuffed and later hollow and thickened towards the base. The color is similar to the hat surface or paler. The meat is very thin, brittle, watery, usually colored gray purple and smells and tastes characteristic of radish.
Microscopic characteristics
The spores are translucent ( hyaline ), long ellipsoid shaped, smooth and measure 5 to 8.5, rarely up to 10 2.5 to 4.5 microns. They can be stained with Jodreagenzien ( Amyloidität ). They grow to a doctorate at the basidia. Cheilo and pleurocystidia are rare to abound and measure 40 to 70 to 10 to 20 microns.
Artabgrenzung
For confusion ( Inocybe geophylla ) and some paint hopper Linge other smells of radish Mycena and the Fragrant, the Schwarzgezähnelte and the Pink Radish Mycena ( Mycena rosea), a color variant of the Erdblättrigen crack fungus come into question. The Fragrant radish Mycena ( Mycena Diosma ) smells sweet, flower -like, after cigar boxes or incense and probably has a few particularly Pleurozystide. The Pink Radish Mycena ( Mycena rosea) has bell-shaped, non-concentric -depth hats. The Schwarzgezähnelte Radish Mycena ( Mycena pelianthina ) has black fins cutting.
Ecology and distribution
He lives as Saprobiont in deciduous and coniferous forests and is pH- indifferent. He is probably spread worldwide and in Europe one of the most common fungi in general. He fruktifiziert May to November.
Toxicology, ingredients and usage
The radish Mycena contain all possible among the different color variations, small amounts of the psychoactive poison muscarine them and have little substance. Therefore they are hardly easy dish purposes. The toxicity is controversial. Previously, the fungus was performed as edible mushroom species in books, today toxic than (weak). He may be produced largely physiologically inactive muscarinic isomers. In a recent study no muscarine could be detected in var rosea ( Pink Radish Mycena ). Furthermore, it enriches boron.
Systematics and Taxonomy
The official first description comes from Christian Hendrik Persoon, who described it as Agaricus prunus in a work published in 1794. On Paul Kummer in 1871 published " leader in the mycology " go the current scientific name and classification back.
Among others, since the fruiting bodies appear to be very variable, many varieties and forms of the fungus are described that can be reliably kept apart but even experts:
- Variety alba Gillet
- Variety carnea Rea
- Variety ianthina Gillet
- Variety lutea Gillet
- Variety luteorosa Bon
- Variety multicolor Bresadola
- Variety purpurea Gillet
- Variety rosea ( Persoon ) J. E. long
- Variety roseoviolacea Gillet " roseo - violacea "
- Variety violacea Gillet
- Form alba ( Gillet ) Arnolds
- Form ianthina ( Gillet ) Maas Geesteranus
- Form lutea ( Gillet ) Arnolds has yellowish hats and purple stems
- Form multicolor has gray-blue -green hats and purple pink stems
- Form purpurea ( Gillet ) Maas Geesteranus
- Form roseoviolacea ( Gillet ) Maas
- Form subaquosa has white fruiting bodies with violet fins union
- Form violacea
It is believed that the type must be divided upon closer phylogenetic genetic investigation. In a genetic study of the ribosomal genome distinguishable strains could be identified, but which do not correspond to macroscopic features such as the hat color. It is therefore suspected environmental factors as the cause of color variations. Among other things, through this study, the aforementioned Fragrant radish Mycena ( Mycena Diosma ) is supported as an independent species. It differs according to the original authors, German Krieglsteiner Josef and Helmut Schwöbel ( in a 1982 publication published ), especially by purple - zoned hat colors, violet fins and smell of cigar boxes; after aforementioned genetic study, the sparseness of the pleurocystidia was a phylogenetically robust train among all members of the group, but the smell and the colors were, however, may not always be reliable distinguishing features.
