Lactarius resimus

The eyelash Milchling ( Lactarius resimus )

The eyelash Milchling ( Lactarius resimus ) is a species of fungus in the family Täublingsverwandten ( Russulaceae ). It is a large and very large Milchling with an initially pure white, ungezonten hat and a white to yellow discoloring milk. The brim is initially hairy fluffy and the stalk never pitted. The predominantly occurring in north-eastern Europe, inedible Milchling is primarily associated with birch and pine. In Central Europe the species is very rare, the fruiting bodies appear in August and September.

Features

Macroscopic characteristics

The hat is 6-15 ( 20) cm wide, gently curved and young umbilicated in the center, then increasingly depressed in the middle. In the age of the edge is spread out and the hat deepened increasingly funnel-shaped. The rim is bent long and is hairy fluffy very young. The surface is more or less smooth, sticky, slimy when wet and shiny. The young hat is colored pure white, then he turns pale cream or pale yellow, and is at least in the middle often pale cream or ockerfleckig. Its not often show poorly developed zones.

The fairly dense, grown wide or slightly on the stem running down slats are rather broad, pale young cream and increasingly colored later reddish ocher. Some are forked to handle nearby. The spore powder is pale cream color.

The cylindrical to bulbous or irregularly shaped stem is 3-5.5 cm long and 2-3 cm wide. The surface is smooth, sometimes velvety at the base and white to whitish- yellow. Sometimes you will find in the lower part of the stem a few ocher pits or blemishes.

The white flesh is firm and in the stem hollow. Bleed it turns under the hat skin and lemon yellow in the stem bark. It tastes only mildly and then slowly sharp, sometimes bitter. The smell is slightly fruity. The white, sparsely milk flowing turns sulfur yellow within 10 to 20 seconds and also tastes hot.

Microscopic characteristics

The roundish to elliptical spores are on average 8.0 to 8.6 microns long and 5.9 to 6.3 microns wide. The Q value (ratio of length and spore width) is 1.1 to 1.45. The incomplete reticular spores ornament is about 0.8 microns high and consists of rows arranged ridges and warts, which are mostly connected reticulate and the few, isolated standing warts. The Hilarfleck is amyloid.

The cylindrical to clavate or bulbous, mostly 4- sporigen basidia are 35-50 microns long and 9 to 11.5 microns wide. The wound - cylindrical to spindle- shaped Pleuromakrozystiden are scattered or rare and are usually only on the disk surface against. They measure 40-70 × 7.5-9 microns. Usually they are not constricted at the top. The blades cutting edge is sterile and filled with 12-40 microns long and 4.5 to 9.5 microns wide, usually septate Parazystiden. These are club-shaped to cylindrical or narrow bottle-shaped and often constricted perlkettenartig at the top.

The hat skin ( Pileipellis ) is a 200-400 micron thick Ixocutis, from lying parallel, 2-7 microns wide hyphae.

Artabgrenzung

The eyelash Milchling resembles particularly the Wässriggezonten Milchling (L. aquizonatus ) and the Fringe Milchling (L. citriolens ). These two species can be distinguished mainly by the fluffy hat brim, the lack of significant zoning and the broader spores. The other major weißhütigen Milkcaps as the wooly Milchling (L. vellereus ) or the Long-stemmed (L. piperatus ) and the green end Pepper Milchling (L. glaucescens ), a white, ( long time) have Invariant milk never be sulfur yellow discolored.

Ecology

The eyelash Milchling is a mycorrhizal fungus that is associated with birch and pine. But possibly also other trees serve as host. It usually takes him on dry, acidic sandy soils, but it can also occur in calcareous sites. The fruiting bodies appear in August and September.

Dissemination

The Holarctic species is in North Asia ( Siberia, Russia Far East ), North America (USA, Canada ) and Europe spread. However, it is not yet clear whether the documents from North America to refer to really like this. In Europe, the Milchling occurs mainly in Fennoscandia and Eastern Europe (Russia). In Scandinavia, it can be locally common. In Central and Western Europe, the fungus is rare to very rare.

In Germany the Milchling in Bavaria, Baden -Württemberg and North Rhine -Westphalia has been demonstrated. In Switzerland, the Milchling is rare.

System

The eyelash Milchling was the first time in 1815 by EM Fries as Agaricus intermedius var expallens and thus described as a variety of milk Grubigen compact. In 1821 he raised him as Agaricus resimus to type before he hired him in 1838 in the genus Lactarius, so he got his today valid name. Further nomenclatural synonyms are: Galorrheus resimus (Fr.) P. Kumm. (1871 ) and Lactifluus resimus (Fr.) Kuntze (1891 )

In Lactarius resimus in the sense of Ricken and Bresadola is L. citiolens Pouzar, the Fringe Milchling. The Artattribut " resimus " means bent upward.

Infra Generic Systematics

M. Basso and Heilmann -Clausen presented the eyelashes Milchling in the sub-section Scrobiculati which stands at Basso below the same section Piperites. In Heilmann -Clausen, however, is the sub-section in section Zonarii. The representatives of the sub-section have a more or less greasy hat whose brim is more or less hairy. The sharp and initially white milk turn yellow after a while. M. Bon represents the Milchling in the section Tricholomoidei. The representatives are similar to those of section Zonarii, but have a woolly - felted hat brim.

Importance

The pungent Milchling applies in Central Europe as inedible, in Russia and Ukraine it is estimated after appropriate pretreatment as an excellent edible mushroom. To make the mushroom edible, two methods are used.
