Lactarius flexuosus
The Bent Milchling ( Lactarius flexuosus )
The Bent Milchling ( Lactarius flexuosus ) is a species of fungus in the family Täublingsverwandten ( Russulaceae ). It is a medium to large-sized grayish to brownish with Milchling, dickfleischigem hat, quite distant lamella and a very sharp taste. The fruiting bodies of the inedible milk Lings appear from late July to early November.

Features
Macroscopic characteristics
The cap is 3-11 cm broad, at first convex, then flattened and depressed in the center, the edge is more or less inflected. Later, the hat is increasingly depressed and the margin gradually spread and often irregularly bent. The dry hat surface is smooth, matt and frosted young and sometimes cracked with age or in the center slightly scaly. When wet it is sticky and shiny. The gray to smoke- gray, pink -gray to purple -brown, clay - ocher-colored or beige hat is zoned often darker in the outer half.
The rather distant lamella are grown on the stem or running slightly down it. They are pretty wide, thick and brittle and sometimes bifurcated into stem area. Young they are a light cream color, later reddish- ocher. The spore powder is pale cream color.
The cylindrical or tapered down stem is 1.8 to 6 cm long and 0.7-4 cm wide. Its surface is smooth or slightly uneven to slightly veined Grooves. He is dry, whitish young to cream with light mauve and frosted, later purple gray, often mottled pale mouse gray and towards the base ocher yellow or cream-colored spots.
The white to cream-colored flesh is firm, thick and full in the stem or stuffed in the hat. It tastes almost immediately very sharp and smells slightly fruity and sour. The white, unchanging and plenty of flowing milk tastes immediately very sharp.
Microscopic characteristics
The almost circular to elliptical spores are on average 7.1 to 7.8 microns long and 5.8-6.2 microns wide. The Q value (ratio of length and spore width) is 1.10 to 1.35. The spores ornament is 0.5-1 microns high and consists of warts and ridges. These are often branched or connected by thin lines and form isolated closed loops. Isolated, often prolonged warts are quite numerous, the Hilarfleck is more or less in the outer part of amyloid.
The rare two - sporig, mostly 4- sporigen and more or less club-shaped basidia are 40-55 microns long and 8.5-10.5 microns wide. The spindle-shaped to lanceolate Pleuromakrozystiden are quite numerous and measure 50-90 × 7.5-11 microns. On the cutting blades sit numerous, fusiform to cylindrical Cheilomakrozystiden and scattered basidia. The Cheilomakrozystiden are 30-70 microns long and 6-8 microns wide and run upward pointed to. Sometimes the tip is constricted also like pearls ( moniliform ).
The hat skin ( Pileipellis ) is a 50-100 micron thick Ixocutis from the majority of parallel, 2-5 microns wide and more or less gelatinized hyphae.
Artabgrenzung
The Rosagezonte Milchling (L. roseozonatus ) provides the Bent Milchling very similar. It differs by the less clearly zoned hat and standing crowded and sometimes spotted fins. This species is now usually regarded only as a variety of Bent Milchling, since the two species do not differ microscopically.
Also the Nordic Milchling (L. trivialis ) can be quite similar and occurs in a similar location. This is but a very slimy when wet hat and stick and is itself always dry out slightly sticky. Microscopically it differs by the much larger spores and a hat skin completely different structure.
Ecology
The Milchling is a mycorrhizal fungus, the preferred living in symbiosis with spruce, birch and pine but also can serve as a host. Maybe he can also be associated with poplars. You can find the Milchling therefore preferred in spruce forests, and interspersed with spruce, birch or pine trees in beech and hornbeam - oak forests on moderately dry, base- and nutrient-poor, grassy or mossy soils. Also on forest roads, forest edges, in clearings and occasionally in parks you can find him. The fruiting bodies appear from late July to early November.
Dissemination
The Bent Milchling is common in North America (USA) and Europe. In Western Europe, it has been demonstrated in France, the Benelux countries and the UK, in central and southern Europe it is found mainly in and around the Alps and Carpathians. In Fennoscandia it is quite different spreads, while it is quite rare in Denmark and Norway, he is in southern and central Sweden and Finland often.
In Germany the Milchling of the coast is spread irregularly and very patchy scattered to the foothills of the Alps and in Switzerland it is not frequent.
System
The Bent Milchling was first described in 1801 by Hendrik Persoon as Agaricus lactifluus flexuosus, and 1821 by EM Fries as Agaricus flexuosus Pers: Fr sanctioned. . In the same year, the British botanist and pharmacologist Samuel Frederick Gray presented him as Lactarius flexuosus (Pers. ex: Fr ) Gray in the genus Lactarius, so that the milk Ling received his currently valid species names. Although it is doubtful whether Persoons original diagnosis of Agaricus lactifluus flexuosus refers to the current way is frieze description in full compliance with the current understanding of the Art
The Latin Artattribut " flexuosus " means curved and refers to the specific type bent brim.
Infra Generic Systematics
The Milchling provided by Basso in the sub-section Pyrogalini, which in turn is in the section Glutinosi. The representatives of the sub-section have any gray, brownish gray, rarely olive-colored, dry or greasy hats. The spore powder is usually cream-colored.

Importance
The pungent Milchling is not edible.
