Clitopilus prunulus
Flour Räsling ( Clitopilus prunulus )
The flour or meal Räsling fungus ( Clitopilus prunulus ) is a agaric from the family of Rötlingsverwandten. It is a productive edible mushroom with white hat surface, decurrent grown fins and pink spores.

Features
Macroscopic characteristics
The fruiting bodies of flour Räslings appear individually or in small groups. They have a 3-9, rarely up to 12 cm wide, fleshy hat. Its shape is initially hemispherical domed and flattens progressively from a (partly funnel- shaped) recessed for rolled towards the edge wavy shape with usually a broad hump. The white to pale gray - beige or yellowish cream-colored surface is at least dry velvety matte and fine frosted, sticky or greasy when wet. The forced standing, narrow strips are young white and colored later Sporenreife by the pink - brown spore powder. The cutting edges are arcuate. You are decurrent grown on a stick. The stem is often eccentrically grow at the hat, überfasert fleshy and whitish. It reaches 2 to 6 inches in length and is 5 to 15 mm thick. The meat is relatively soft. It smells and tastes typically flour or cucumber -like.
Microscopic characteristics
The almond-shaped to ellipsoid shaped spores measure 9 to 14 5 to 6.5, rarely to 8 microns and are 6-8 times along ribbed. The viersporigen basidia measure 25-47 to 7-12 microns. The hat skin is a cutis or Ixocutis from 3 to 7 microns of cylindrical hyphae.
Artabgrenzung
Main distinguishing features are the pink ripe ( brown ) spores that turn the slats accordingly, and the strong flour-like smell and taste.
Hazardous confusion opportunities exist with toxic white funnel Lingen as the deadly poisonous field Trichterling ( Clitocybe dealbata ) or the Lead White Varnish Trichterling ( Clitocybe phyllophila ).
The now considered toxic applicable Büschelrasling White ( Lyophyllum connatum ) has white spores powder.
Distribution and ecology
This is not rare species lives in typically rich soils in mycorrhizal symbiosis with trees mainly in forests and fruiting from July to November. His appearance in ecologically very diverse habitats shows little special requirements.
The species is widespread and common in Germany.
Ingredients, composition
The cucumber -like odor was attributed to trans-2- nonenal, which is produced in violation of the fruiting body and then in a concentration of 17 micrograms per gram of minced mushroom tissue is present. The included volatile compound 1- octen-3 -ol is making the way unpalatable to the banana slug ( Ariolimax columbianus ).
Importance
The flour - Räsling is a good and productive Mushroom, which, however, slightly toxic white funnel Lingen, such as the lead White Varnish Trichterling, can be confused. The gathering to feed purposes is therefore only recommended connoisseurs.
Systematics and Taxonomy
The official scientific description comes back from a 1772 published work of Joannes Antonius Scopoli. The local designation as Agaricus prunulus was sanctioned by Elias Magnus Fries in 1821 published work. 1871 Paul placed the taxon in his grief to " the leader in the mycology " the kind of Räslinge ( Clitopilus ).
The Latin species epithet " prunulus " ( " Pfläumchen " ) takes on the comparison with plums respect to the tires of the hat skin. This reference is also found in the German designation as " plum mushroom". Go back both the German and the English common name designation as " miller" ( German "Miller" ) on his flour-like smell.
