The orange-deaf or yellow birch-deaf ( Russula aurantiaca ) is a fungus from the family of the deaf relatives (Russulaceae). It is characterized by a brick orange hat, but it can also be coppery with carmine tones. The stem is white and the lamellae are ocher to golden yellow.

features

Macroscopic features

The hat is brick orange, apricot orange, sometimes also bright brick red. It reaches a diameter of six to ten, sometimes 14 centimeters, is not strong and slim. The center is bright red to copper in color. In old age she is slightly depressed. The lamellae are tinted yellow; later they turn quite dark yellow. They stand crowded and free from the stem.

The stem is white, often pink, but rarely completely white and has a wrinkled surface. It becomes four to seven inches long and one to two inches thick. The flesh is also white, soft and fragile. It tastes mild and does not smell, or it smells slightly fruity. However, after prolonged chewing, a persistently sharp taste sets in. With phenol it turns salmon red, then wine reddish chocolate color.

The spore powder is golden yellow.

Microscopic features

The spores are briefly ovate to briefly ellipsoidal; they measure 7–8.5 x 6–7.5 micrometers. On the surface there are isolated to weakly connected, coarse warts or spines that are up to a micrometer long. The cystids are spindle-shaped and react weakly with sulfovanillin . Those on the top of the hat (pilocystidia) are between four and nine micrometers wide and often crossed several times by partition walls (septate).

Species delimitation

The orange-red gray-stalked deafblings ( Russula decolorans ) can be very similar . He has blackened flesh and light-colored spore powder. If the red-stalked dwarf bling ( R. fontqueri ) is recognized as an independent species, it only differs by a lighter, pale yellow spore powder. Further features are slightly wider pilocystic periods and occasional protuberances. However, both properties are not constant. Because of this strong similarity, it is discussed to lead this species as a variation of the Orange-Deaf.

ecology

The Orange-Täubling can be found in damp to slightly boggy places under birch , oak and beech trees . The fruiting bodies appear between July and October.

distribution

European countries with evidence of finding of the orange pigeon.

    • The orange-blubber is common in Europe, where it can be found from France, the Netherlands, Great Britain and the Hebrides in the west to Poland in the east. To the south the area extends to Austria and in the north to Norway, where it penetrates into subarctic birch forests. The species is rare to very rare everywhere. It is only found sporadically in Germany.

    meaning

    The orange blubber is edible.
