Cystolepiota seminuda

Behangener flour Schirmling ( Cystolepiota seminuda )

The inedible draped flour Schirmling ( Cystolepiota seminuda, syn. Cystolepiota sistrata, Cystolepiota sororia ) is a species of fungus in the family of mushroom relatives ( Agaricaceae ). The small, whitish Schirmling is mealy young frosting and often hung at the brim with Velumresten. The fruiting bodies appear from July to November in mostly deciduous, rarely also in the coniferous forest. It is also called White flour Schirmling or Petite flour Schirmling.

Features

Macroscopic characteristics

The hat is 0.5-2.5 cm broad, at first conical to bell-shaped, then convex to spread. The matte, uniform white young floured surface is pure white colored to pale yellow. The Hutmitte is usually dull and often hunched yellow brownish or pinkish gray to purple. Young fruit bodies have a flaky draped brim, at the age of edge is often bent upwards.

The rather forced standing, whitish fins are free and are intermingled with numerous intermediate fins, the spore powder is white. ( In the variety sororia the fins are yellowish. )

The stem is 2-5 cm long, 2-4 cm wide, white and often slightly curved. He, too, is white flaky frosting to mealy and later turns reddish wine especially when touched from the bottom to purple - brown. The very thin meat tastes mild, the smell is weak and a little reminiscent of the Stink - screen Ling. ( Food trials should be avoided as some small pieces of screen can be organ- damaging already at cost! )

Microscopic characteristics

The kurzellipsoiden spores are 3-4.5 microns long and 2-3 microns wide. In the variety sororia they are long - ellipsoid, up to 6 microns long. Cystidia absent on the fins.

Artabgrenzung

The draped flour Schirmling is characterized within its genus by its more or less whitish hat that does not dextrinoiden spores and the absence of cystidia on the lamellae surfaces and cutting. Other similar species outside of the genus are the white grains Schirmling ( Cystodermella Ambrosii ), the White Parasol mushroom ( Lepiota erminea ) and the strong -smelling granules Schirmling ( Cystoderma carcharias ).

Ecology

You can find the fungus mainly in deciduous forest communities, especially in beech and various Au, but also in hornbeam - oak forests. From pure coniferous forests or forests, there are only a few certificates. The fruiting bodies appear remarkably often along roadsides. The Schirmling loamy, nutrient-rich soils that are neutral to basic mostly. In heat- favored locations it grows well on a slightly acidic soils. The fruiting body usually appear sociable July to November, but usually you can find him in the summer and early fall.

Dissemination

The fungus is found in North America (Canada, USA), North Africa (Morocco, Algeria) and Europe. He has also been detected in Australia and Asia (Japan). In Europe the species is meridional spread to temperat. In northern Europe, the distribution area in Norway extends to the 69th and in Sweden up to 63 degrees latitude.

In Germany, the draped flour Schirmling is widespread only in the North German Plain and in the areas with predominant coniferous forest it is scattered to rare.

Importance

Although no toxic effect is known, small screen blanks should never be collected for food purposes.
