Features
Macroscopic characteristics
The hat is initially conical, later convex to spread and hunched. He is colored pink to reddish pink. Sometimes he has a cream-colored to pale ocher union apex. The margin is usually more brightly colored and ribbed translucent. The surface is smooth and often wavy and hygrophanous. The lamellae are initially whitish, later increased with pink tone and bulged on a stick. They are interspersed with shorter wide and intermediate lamellae. You are connected to the base with cross- veins and have a smooth edge.
The shaft to a length of five to eight centimeters and a width of between three and eight millimeters. He is cylindrically shaped and tapered at the top. Its interior is initially fleshy, at the age he is hollow. He is white, sometimes tinted pink. There is a white, striegeliger felt at the base. The meat is thin, soft and whitish in color. It smells and tastes like a radish.
Microscopic characteristics
The spores are hyaline and measure 6.5-7.5 × 4-5 micrometers. You are breitelliptisch formed, its surface is smooth and they have a drop. The spores react amyloid.
Artabgrenzung
The Pink Radish helmet Ling has some closely related species similar. Better known is the Common Radish Mycena ( Mycena pura ). The Pink Radish helmet Ling was formerly considered a variety of this kind. It is usually somewhat smaller, has a flatter, less conical hat and a concentric recess. He is also less pink, more violettlich colored. Also similar is the Schwarzgezähnelte Radish helmet Ling (M. pelianthina ) with dark fins cutting. Possibility of confusion exists with the rare flesh -colored helmet Ling (M. pearsoniana ), which has strongly arched decurrent lamellae and inamyloide spores.
Ecology
The Pink Radish helmet Ling is a typical representative in mesophilic and calcareous beech and book -rich mountain mixed forests. However, it can also occur in other companies with beech trees. Chance is the kind found in various plantations.
The fungus forms an ectomycorrhizal with deciduous trees, especially beech. Chance he is also reported together with conifers. The fruiting bodies are formed between September and early November and are mostly in small groups in the fall foliage. Sometimes, however, they appear in early summer or in December.
Toxicology
The Radish Mycena contain all the poison muscarine and therefore should not be consumed. The Pink Radish helmet Ling is the most toxic among the radish Helmlingen. According to recent studies, however, is no guarantee that it is the toxin actually is muscarinic, since with modern and highly sensitive mass spectrometric methods could not be detected in M. rosea. The red color of the fruit body is due to the Pyrrolochinolinalkaloid Mycenarubin A. Similar Pyrrolochinolinalkaloide of which act some antitumor active, are known, interestingly, from marine organisms.
Dissemination
The Pink Radish helmet Ling is common in Europe and in the Caucasus. The area ranges from France to Romania and the Ukraine, as well as south to Spain and the Balearic Islands, Italy, Bulgaria and to Denmark, Southern Sweden, Finland and Estonia in the north. In Germany, the fungus can be found in the limestone areas of the colline and montane locations. Thus, it is not evenly distributed throughout and clearly incomplete common than the Common Radish Mycena ( Mycena pura ).
