Omphalotus olearius

Dark olive tree Trichterling ( Omphalotus olearius )

The Dark olive tree Trichterling ( Omphalotus olearius ) is a mushroom in the family of Schwindling relatives. The scientific name means " genabelter Ohrling " ( = Omphalotus ) to " olive tree growing " ( = olearius ). The German name "Shining olive tree mushroom" refers to the bioluminescence of the mycelium and the lamellae: light up in the dark.

Features

The relatively dünnfleischige hat is yellow to bright orange to olive trees it is tinged rust- brown. It reaches a height of six to ten centimeters. The cap is initially convex, then spread out flat and finally depressed or recessed funnel-shaped. The edge is often rolled up and the hat skin smooth. The stem is five to six inches long, orange to fuchsigbraun colored, tapering towards the base. He is tough and straight-grained. The hat is often not centrally grow. The fins have a bright golden yellow, closely set and run on a stick down; they glow in the dark, when your eyes have switched to night vision. This - Foxfire - called lights is triggered by the enzyme luciferase and is a form of bioluminescence. The principle of operation is similar to the firefly. The flesh is yellowish to orange- tinted as well as tough and fibrous. It smells of softwood and has a mild flavor. The spores are tinted yellow.

Artabgrenzung

Where it occurs, together with the chanterelle in the same habitat, it is easily confused for laymen. During the chanterelle is pale yellow to yellow yolk, the olive tree Trichterling is more orange yellow orange-red to. However, the olive tree fungus always grows on wood, the chanterelle always on the ground; as well as the similar foxy Rötelritterling. In addition, there are probably still a very similar kind Omphalotus illudens that is not recognized by all mycologists as a separate species.

Ecology and phenology

The Dark olive tree Trichterling lives parasitically or saprobiontisch on deciduous trees. It grows mostly on oil tufted trees, sometimes in oak or chestnut. The fungus appears from July to October.

Dissemination

The heat-loving Dark Olive Trichterling is widespread in the Mediterranean, Central Europe, very rare.

Importance

The Dark olive tree Trichterling is very toxic, if not lethal toxic and triggers a gastrointestinal intoxication from; mild liver damage can not be excluded.
