Einhell.

The carmine blotch or band-spore blotch ( Russula taeniospora syn. R. carminea ) is a fungus from the family of blotch relatives (Russulaceae). The very rare Täubling is reminiscent of the purple-black Täubling with its purple and almost blackish hat . The hat is usually only up to five centimeters wide and smells like fresh apples.

features

Macroscopic features

The hat reaches a diameter of three to six centimeters. It is colored purple and later carmine pink. In young specimens and in the middle it is longer blackish and tinted lighter purple at the edge. The consistency is fleshy but fragile. The blunt edge is ribbed and bumpy and sometimes flaky white when young.

The lamellae are whitish and have no yellowish sheen. They are (3.5) 5.5–10 mm high and are connected to one another in a veiny or wrinkled manner. The cutting edges are mostly smooth and only rarely lightly sawn. The spore powder is whitish to slightly cream in color ( Ib to almost IIa according to Romagnesi ).

The white stem is (2) 3.5-5 cm long and 0.8-1.5 cm wide. It is cylindrical in shape and often tapered at the base, but sometimes also expanded at the top and briefly thickened at the bottom at the base. The base is seldom tinged with pink. The very fragile stem soon becomes more or less hollow inside and often brown spots at the base.

The flesh is white, but turns a little gray and is soon frail. It smells a bit like fresh apples or vinous breath and tastes relatively hot. The guaiac reaction is strongly positive.

Microscopic features

The spores are ellipsoidal in shape and measure 7–8.5 x 6–7 micrometers. The surface is banded with fine black to fine prickly and burrs. The warts are up to 0.85 micrometers high and sometimes stand in a string of pearls, but never closed net. The cystidia are club-shaped or head-shaped and have small, differently shaped tips. They are between 55 and 64 micrometers long and 7-10 (12) µm wide. The basidia are 36–44 (–55) wide and 10–12 (–14) µm long.

The 2.5-4.5 (-5.5) µm wide cap skin hyphae (hyphae end cells) are quite large and multiform in shape. They are usually blunt and more or less cylindrical. The 6–12 (–14) µm wide Pileocystiden are very common. They are cylindrical, club-like or blunt and 0–3 times septate. They often have short end cells.

Species delimitation

The purple-black blubber looks very similar to the crimson.

The carmine blubber can be confused with other species of the subsection Atropurpurinae . The closely related purple-black blubber ( R. atropurpurea ) is very similar . However, this usually reaches a hat diameter that is over five centimeters.

ecology

The carmine blubber is said to be found under spruce , red beech , birch and linden . There it occurs on fresh to moderately dry soils.

distribution

European countries with evidence of finding of the crimson pavilion.
Legend:
  • Countries with found reports
  • Countries without evidence
  • no data
  • non-European countries

    • The rare carmine blubber is common in Europe and North Africa (Morocco).

    The Täubling is very rare in Germany, the only verifiable finds are in Bavaria and Brandenburg. The Täubling is listed in the RL 1 hazard category on the German Red List .

    Systematics

    Inquiry systematics

    The Ruby is Täubling of Bon in the subsection Atropurpurinae found within the section Russula stands. The species of this group all have different colored, mostly purple, violet or reddish, but never pure red hats. They all taste more or less hot and have white spore powder.

    meaning

    The carmine blubber is inedible.
