The violet or amethyst blue lacquer funnel ( Laccaria amethystina ) is a type of mushroom from the family of heather truffle relatives . The also called Violet Bluebird or short Bluebird known species as all paint clitocybe edible. It owes its name to its consistently violet coloration, which turns out very strong violet to lavender when wet and fades to light violet to almost white when dry.
features
Macroscopic features
The purple lacquer funnel is small to medium in size. Its most important distinguishing feature is its deep purple color when fresh and damp; however, when dry, the fungus fades and can turn almost white. The hat with a diameter of 2–6 cm is flat to arched and often becomes wavy with increasing age and appears to be nicked. The 4–10 cm long and 4–8 mm wide, stiff stalk is usually slightly fibrous and covered with mycelial felt at the base . It has relatively few, far-reaching lamellae, which, like the whole mushroom, are purple in color. In contrast to hats, however, their color is retained when they dry, they do not fade whitish. They are plump, waxy and quite broad. The spore powder is white and inamyloid . The flesh is purple and streaked with water. It smells and tastes inconspicuous to imperceptible.
Microscopic features
The spores are round-oval in shape and 7-10 micrometers in diameter. The surface is covered with sharp spikes that are approximately 2 micrometers long. A germ pore is missing.
Ecology and phenology
From summer to autumn it is particularly widespread in deciduous and coniferous forests. There it grows in damp places on leaves and coniferous litter.
meaning
The violet lacquer funnel is - like all lacquer funnel - edible and with its mild taste suitable as an edible mushroom . Specimens that are purely purple in color are said to be more suitable for consumption. After the reactor disaster in Chernobyl in 1986, the fungus showed very high cesium -137 values because it accumulates it. Since the isotope has now sunk into deeper soil layers, it is no longer reached by the mycelium near the surface , so that the pollution is now well below the limit value for food of 600 Bq / kg. The species enriches the carcinogen dimethylarsinic acid , which is why it should only be consumed in small quantities and should be avoided from areas polluted by iron processing or mining, for example.
