The wine-red yolk-deafening ( Russula decipiens ) is a fungus from the family of the deaf relatives . The very rare, sharp-tasting blubber has a flesh-pink colored hat with a mostly cream-colored center. Its spore powder is colored intensely yolk yellow. In southern Germany the Täubling can sometimes be found in oak forests on better soils.

features

Macroscopic features

The hat is 5–10 (–12) cm wide and initially arched, but soon depressed. The edge is curved for a long time and slightly furrowed with age. The hat skin is smooth and shiny and partly drawn over the lamellae. It can be peeled off and is often finely wrinkled with age.

The grown, fairly wide lamellae are very brittle. They are more or less forked, almost bulbous and blunt. In young fruiting bodies they are yellow in color, in ripe ones they are deep orange. The spore powder is yolk yellow ( IVd-e according to Romagnesi ).

The initially white stem is (3–) 6–8 (–10) cm long and 1.5–2.5 cm wide. It is almost cylindrical or slightly club-shaped and becomes hollow with age. At the top it is often floured and otherwise finely wrinkled. It is becoming increasingly brownish and can be a little gray from the base.

The firm flesh is dirty whitish and almost grayish in the pulp. It has no or only a weak, fruity smell that is a little reminiscent of the cherry red Spei-Täubling . The taste is moderately sharp. The meat turns pinkish-orange with iron sulfate and reddish brown with phenol . It also reacts intensely with guaiac.

Microscopic features

The spores are 8-10 µm long and 7-8 µm wide and covered with warts, which are often in chain-like rows and are connected in places with burrs. The cystidia are up to 100 (–130) µm wide and 10–15 (–20) µm long. They are spindle-shaped to bulbous, more or less appendiculated or conically pointed.

The club-shaped Pileocystiden are up to 100 (-150) µm long and 10-13 µm wide. They are not or are simply septate. The 3–2 (–1) µm wide hyphae end cells are elongated, convoluted or rarely clubbed.

Species delimitation

The sharp vermilion deaf ( Russula rubra ) is quite similar , but it has stronger red tones.

ecology

The wine-red yolk deaf, like all deaf, is a mycorrhizal fungus that can enter into a symbiosis with various deciduous trees . Hornbeams , red beeches and oaks can serve as hosts for a symbiotic partnership . The Täubling can sometimes be found in light, summer-warm hornbeam oaks and red beech forests with mixed oaks. But it also occurs in parks.

The fungus prefers neural to alkaline, nutrient-rich, sandy to loamy soils over lime, base-rich silicates and marls. The fruiting bodies appear from early summer to early autumn.

distribution

European countries with evidence of finding of the Wine Red Dotter-Täubling.
Legend:
  • Countries with found reports
  • Countries without evidence
  • no data
  • non-European countries
  • The wine-red yolk blubber is widespread in North Asia (Russia-Far East), North Africa (Morocco) and Europe. In Europe it is widespread from Spain in the south, through France Benelux to Great Britain in the west and to southern Scandinavia in the north. In Finland it occurs only in Åland .

    The Täubling is very rare in Germany, north of the 53 degree latitude it is completely absent. On the red list , it is listed in the risk category RL2.

    Systematics

    Inquiry systematics

    The wine-red yolk-blubber is placed in the Maculatinae ( Urentinae ) subsection within the Insidiosinae section (Subgenus Insidiosula ). The representatives of this subsection usually have red, yellow or purple hats. They taste hot and have a yellow spore powder.

    Subspecies and varieties

    • Russula decipiens var. Vermiculata Romagn. (1988)

    The hat is 3–5 cm wide and is pink to reddish in color, but paler than the type. It has a cream-colored center and often gray-whitish discoloration. The hat skin is shiny on the edge in the middle rather matt. It can be peeled off up to 1/3 of the radius. The lamellae are golden yellow, the spore powder is intensely yolk yellow (IVe according to Romagnesi). The meat tastes very hot, sometimes slightly bitter and tends to yellow and gray. The Täubling can be found under European beech in the Mediterranean area.

    meaning

    The wine-red yolk-deaf, like all pungent-tasting deafblings and like all representatives of the Maculatinae subsection, is inedible or slightly poisonous.
