The inedible violet vertebrate ( Marasmius wynneae , syn.  Marasmius wynnei ) is a type of mushroom from the family of vertigo relatives (Marasmiaceae). The gregarious, sometimes tufted fruiting bodies appear from June to November in deciduous forests.

features

The flaky, frosted stalk of the violet swindler is cream-colored at the top and red-brown at the bottom.
The elliptical, smooth spores are translucent and often contain drops.

Macroscopic features

The hat is 2–4 (–7) cm wide, hemispherical when young, soon arched flat or bluntly hunched and often somewhat bent. The matt frosted and often wrinkled surface is bare, hygrophan and, when damp, grooved almost to the middle. The hat color is very changeable, but usually has a slightly purple tint. Otherwise, the hat can be almost whitish to pale brownish (horn gray, violet gray, gray-brownish) in color. The colors fade strongly when drying. The edge is paler and bent wavy.

The distant, thick lamellae are bulged on the handle and run down it with a narrow tooth. They are whitish to cream-colored or gray-purple in color. The blade edges are smooth or jagged. The spore powder is white and shows no color reaction ( inamyloid ) when an iodine reagent is added .

The cylindrical to flat, sometimes twisted stalk is 3–7 cm long and 0.2–0.8 cm wide. It is stiff, elastic and hollow and flaky frosted over its entire length. In the upper part it is cream colored, towards the bottom it is increasingly reddish brown. Fine mycelium usually adheres to the base of the stalk , which can often cover large areas under the leaf litter as a dense felt. The thin meat ( trama ) is white in the hat and smells and tastes unpleasant. A slight bitter almond or hay smell may be detectable.

Microscopic features

The elliptical, smooth spores are 5–8 µm long and 3–4 µm wide. They are translucent ( hyaline ) and often contain drops. The cell threads of the hat skin ( epicutis hyphen ) consist of round and smooth elements ( spherocysts ).

Species delimitation

The purple vertigo looks similar to the edible carnation vertigo . But this one has more yellow ocher colors and a lighter stem, and it lacks the purple tint. In addition, the purple vertebrate grows preferentially in deciduous forests and the carnation vertebrate in meadows.

Ecology and phenology

The violet vertigo fructifies in tufts and in rings in the leaf litter.

The fruiting bodies of the very common violet vertigo appear from June to November mostly in tufts and growing in rings in deciduous forests. The species fructifies on the leaf litter and sometimes on rotten wood. The dizziness is particularly common in limestone areas.

meaning

ingredients

The violet swindler belongs to a group of fungi that excrete traces of hydrogen cyanide gases. The amount released is completely harmless to humans, but snails in particular are very sensitive to it. Experiments have shown that snails locked in a larger, closed box with these mushrooms die after a few hours.

Food value

The Violet Schwindlings is not an edible mushroom.
