The Wrong Cinnabar Täubling or Rosarote Täubling ( Russula lepidicolor ) is a mushroom from the family of Täublingsverwandten . It is a very rare Bluebell with a red to dark red hat, whitish lamellae and a mild taste, which is closely related to the fuzzy pink Bluebird ( Russula rosea ). Its flesh is colored typically eosin red with sulfovanillin .

features

Macroscopic features

The hat is 5–7 (10) cm wide, first arched then spread out. Sometimes the hat is also deepened in a navel shape. It's quite firm and fleshy, but later noticeably softer. The edge is blunt, often curled up, smooth and sometimes irregularly lobed. The hat skin has grown, when it is wet it can be smeary and shiny, when it is dry it is rather dull. At the edge it is almost wrinkled, sometimes almost concentric, as in the red-stemmed leather blubber . The hat is brightly colored crimson, sometimes almost purple. Also dark red to purple black in the middle. Often the hat color is pale cream or ocher.

The rather dense, whitish to light cream-colored lamellae are quite dense. They are 4–10 mm high, often soft or fragile, more or less cross-veined at the base and blunt to the edge. The spore powder is also whitish and does not tend to yellow.

The white or mostly one-sided slightly pink stalk is (3–) 5–8 (–10) cm long and 1–2 (–3) cm wide and almost cylindrical to slightly club-shaped. It is quite firm when young, but later often stuffed spongy on the inside. Wrinkled at least in old age. The tip of the handle is never frosted in a fuzzy manner.

The flesh, which is almost odorless and tasteless, is firm and white, except under the cap skin. Inside, it can sometimes be a little dirty white, like the ocher-leaved vermilion blubber . The guaiac reaction is weak and slow, with iron sulfate the meat turns a dirty pinkish-gray. Dry material in particular turns an intense red color with sulfovanillin.

Microscopic features

The spores are 6.5–8 (–8.5) µm long and 5.5–6.5 (–7) µm wide and have a fine, warty-ridged and partially reticulated ornament. The 8.5–11 µm wide cystidia are usually spindle-shaped and, at 40 to 60 µm in length, quite short. They often have yellowish inclusions and only react weakly with sulfobenzaldehyde. The basidia 30–50 µm long and 8.5–11 µm wide.

The cap skin contains no dermatocystids and variable shaped hyphae end cells 2–4 (-5) µm wide, which can be branched, blunt, or rarely narrowed or clubbed. Sometimes they are twisted or slightly heady. The 5–6 (8) µm wide primordial hyphae are cylindrical to clubbed and have a coarse, only slightly firm incrustation that is up to 3 (–5) µm thick.

Species delimitation

The small pink deaf ( Russula minutula ) has a certain similarity, but it is usually much smaller and its hat is rarely up to 4 cm wide.

The fuzzy pink blotch ( Russula aurora ) can also be similar, but the hat skin shines more, is overall lighter in color and is easier to remove.

Most similar is the hard cinnabar deafblings ( Russula rosea ), which have the same appearance. It can be distinguished by its cedar-like smell and the bitter taste of menthol. Pileocystides can be detected in the hat skin .

Ecology and diffusion

European countries with evidence of discovery of the false cinnabar pewter.
Legend:
  • Countries with found reports
  • Countries without evidence
  • no data
  • non-European countries

    • The pink blubber is a rare European species that is found predominantly in Western and Central Europe. However, it is rare everywhere, only a few individual finds are known from Great Britain and the Netherlands. In northern and southern Europe, the species seems to be completely absent.

    In Germany it was found sporadically in Saarland, Baden-Württemberg and Bavaria, north of the Main it seems to be completely absent.

    As a mycorrhizal fungus, the deaf fungus can enter into a symbiotic partnership with various deciduous trees. In Germany he seems to prefer hornbeam and red beech . In France it is also found under chestnuts . On the Red List of Endangered Species in Germany, it is classified in hazard category RL 2.

    Systematics

    Inquiry systematics

    The false cinnabar deaf is placed by Bon in the subsection Roseinae , which in turn is within the section Lilaceae ( Incrustatae ). The subsection mostly contains large or medium-sized species, with red, pink or whitish hats that are often frosted. The stem is tinted white or pink and turns reddish in color with sulfovanillin or sulfobenzaldehyde. The taste is mild, but sometimes also bitter.

    meaning

    The false cinnabar blubber is edible, but due to its rarity it is easy to conserve.
