Features
Macroscopic characteristics
The hat of the Violettstieligen Täublings is hemispherical at a young age and with age arched to spread. Older mushrooms have a hat whose center is depressed. The surface of the hat is feinsamtig and dry. At a young age he is bright sulfur yellow that yellow, yellow-green to purple with age to a then, dark purple changes to brown clay. It measures between two and nine inches in diameter.
The lamellae are grown on a stick. They are whitish young and change with increasing age of the fungus from cream, through sulfur-yellow to straw- yellow to. You may feel slightly greasy and are quite crowded, per centimeter are 15 to 17 blades, with ganzrandiger cutting.
The stem of the mushroom is of three to eight centimeters long and about 0.5 to 2 inches wide, usually cylindrical in shape and tapered at the base, or spindle-shaped. When young it is colored white and discolored in age more and more purple.
The meat is tough and has a white color. It tastes mild and smells aged significantly after cooked crabs or herring -like.
Microscopic characteristics
The spores are oval to almost spherical, 6-9 microns long and 6-8 microns wide. They are light yellow and as the spores of all russulas amyolid. The warts are 0.7 - 1μ connected high and over lines or ridges together to form a fairly well-developed network. The basidia are club-shaped and 30 to 40 microns long. They are 8.5 to 11 microns wide and carry 3-4 spores. They are hyaline. Pileozystiden missing and pleurocystidia are rare and can not be stained with Sulfovanillin. The fin edge is fringed with tapering cells. The hyphal end cells of the hat skin usually run too narrow, the supporting cells are usually inflated, sometimes even balloon-shaped.
Ecology
The Violettstielige Täubling like all russulas a mycorrhizal fungus, the preferred with beech enters a partnership. More rarely, oak trees can serve as host and much more rarely spruce.
The Täubling, the acidic soils preference is therefore usually occurs in Luzulo beech forests and acidic forms of woodruff -beech, fir and cleavers - hornbeam - oak forest. When oaks or beeches are interspersed it is found also in spruce forests or forests. He also happens to forests and roadsides.
The Täubling like flat ground, nutrient and low in calcium, moderately dry to fresh soils. The fruiting bodies appear from June to September. One finds the way from the plains to the high mountain country.
Dissemination
The type is in Europe and Asia (Japan, Korea, Taiwan), North Africa (Morocco ) and North America (USA) spread. In Europe, their distribution area of the temperate zone extends into the Mediterranean.
In Germany the species is moderately common, with significant gaps in Northwest Lower Saxony as well as in all limestone areas.
System
Infra Generic Systematics
The Violettstielige Täubling is in the subsection Amoeninae which is available within the section Heterophyllae. The russulas this subsection have reddish to purple colored, usually velvety matte hats that can be colored more rarely greenish, brownish or yellowish. They taste mild and smell at least the age crabs - up herring -like. Your spore powder is cream colored.
