Lactarius controversus

The Rosascheckige Milchling ( Lactarius controversus )

The Rosascheckige Milchling or Blutfleckige Milchling ( Lactarius controversus ) is a species of fungus in the family Täublingsverwandten ( Russulaceae ). It is a very large white Milchling with a mostly concentric pink speckled hat. The steady, white milk tastes very sharp. You usually find it at Black and aspens.

Features

Macroscopic characteristics

The hat is 8-20, yes up to 25 cm wide and initially curved with rolled, slightly downy - tomentose hairy edge, then spread and depressed in the middle or depth of a funnel. In older fruit bodies of the edge is smooth and bare. The hat is ivory to pale yellow leather and often indistinct, and particularly towards the edge concentrically zoned or mottled pink. Young and in damp weather the hat is very greasy - sticky.

The yellowish-white, later cloudy pink flesh slats are pretty tight and run something down on a stick. Sometimes the fins are bifurcated into stem area.

The short stem is 2-5 cm long and 1-2 cm wide, white- downy, later glabrous, and 1-2 cm wide, tapering towards the base.

The milk is white and unchanging tastes and fiery-hot after some time. Also the solid meat tastes very sharp and has a weak fruit -like odor. The spore powder is cream colored with a pink reflex.

Microscopic characteristics

The spores are 6-7 microns long and 5-6 microns wide and filled with rich, down to 0.5 microns high warts that fused into thick ridges that form a fairly complete network. The approximately 45 microns long and Pleuromacrozystiden Cheilomacrozystiden come right in scattered and are unremarkable. They are tapered or spindle- shaped or drawn together at the top. Pileipellis is a Ixocutis.

Artabgrenzung

The Milchling can hardly be confused with another Milchling. Specific type and characteristic are the following features:

  • The large, greasy with moisture until sticky white hats that are usually mottled pink.
  • The white, unchanging and burning hot milk
  • The cream- yellow to flesh- pink fins, but always have a pink reflex.

Ecology

The Rosascheckige Milchling is a mycorrhizal fungus, which normally enters into with poplar trees, especially with black and aspens, sometimes with willow, a symbiosis.

You can find the Milchling therefore in alder and field elm floodplain forests in aspen and poplar forests and parks, but also on grassy roads and roadsides on weak to strong iron-containing, usually nutrient - and N- rich soils. It occurs equally in acid to alkaline soils, such as basalt, loess, sand, loam or clay or silicate rock soils. On his site he often occurs in larger quantities and grows mostly tufted, often in rings or rows.

The fruiting bodies appear in summer and autumn from the lowlands to the mountains.

Dissemination

The Rosagescheckte Milchling comes in North Asia before ( East Siberia ), North America (USA), North Africa (Morocco ) and Europe. In Europe, it has been demonstrated in the south of Spain to Bulgaria, in the west of France to the UK and as far east as Russia. In Northern Europe it is rare, but has been detected in the entire southern Fennoscandia.

In Germany the Milchling is widespread but not very often. He comes from the North Frisian Islands and the Baltic coast to the foothills of the Alps widely dispersed before. Slightly denser spread it is only in the Stromtalauen as well as in the eastern Saarland. On the Red List he is listed in the hazard category RL3.

System

Infra Generic Systematics

The species belongs to the section Zonarii and is not, as one might suspect, perhaps, related to the other big white milk Lingen section Albati. The representatives of the Section have something greasy and sticky hats, which are more or less zoned. The milk is white and stays that way, also the spore powder is white or cream-colored.

Importance

Because of its very sharp taste of the milk Ling is considered inedible.
