The fuzzy pink blotch ( Russula aurora syn .: R. rosea (non ss. Pers. ) And R. velutipes Velen. ) Is an edible mushroom from the family of blotch relatives . He is a mild-tasting, medium-sized deaf, with a hat that is often lightly red-colored. The tip of the handle is typically powdered with a flaky net. Another important feature is the sulfovanillin reaction of the meat, which turns eosin-red in color. The Täubling has a whole range of different names: it is also called the Pink Täubling , Big Pink Täubling or Morgenrottäubling .

features

Macroscopic features

The hat is 5–10, sometimes up to 12 cm wide, slightly depressed with an inwardly curved edge. The color is pale pink at the edge. Towards the middle it fades more or less cream-ocher, in between it is salmon pink. The cap skin often has pale to yellowish, broad spots. It is dull or matt and can only be removed at the edge. The edge remains smooth for a long time.

The lamellae are soft, (sometimes almost pulpy), blunt, more or less cross-veined or forked. They are whitish to cream in color and sometimes have a misleading yellowish tinge.

The mostly pure white stem is up to 12 (15) cm high and 2–3 cm thick, sometimes even thicker. It is rarely tinged with pink. It is club-shaped and often widened at the base of the hat, typically it is powdered there like a net. At the base, the stem is smoother or veiny and can sometimes tan slightly. It is not as firm as the handle of the hard cinnabar buttocks , but is quickly stuffed and quite fragile.

The white meat is also fragile and tastes mild (it can sometimes taste very slightly bitter only when young, but it never tastes like pencil wood.) The smell is insignificant, the deaf can possibly smell slightly fruity. The spore powder is whitish, but it can turn yellow when dry.

The flesh turns blue-green only slowly with guaiac . Iron sulfate causes a dirty, often ambiguous discoloration. With sulfovanillin the meat turns bright pink, sometimes the reaction is also weak (with dry material you get better results).

Microscopic features

The spores are 6–8 µm long, 5–6.5 µm wide and covered with low, line-shaped warts. The basidia are 42–46 µm long and 7–8 µm wide with four sterigms. In the cap skin ( epicutis ) there are primordial hyphae 4–6 µm wide and curled eyelash hairs. Pileocystides are absent or cannot be detected.

ecology

Like all deafnesses, the fuzzy pink deafness is a mycorrhizal fungus , which can usually be associated with deciduous trees and, more rarely, with conifers. In Central Europe, the European beech is his preferred symbiotic partner. In addition, spruce , oak , hornbeam and other deciduous trees can serve as hosts. The taubling is most often found in strongly to weakly acidic red beech forests, such as hornbeam and red beech forests , woodruff beech forests and, more rarely, in bedstraw-fir forests . But it can also be found in corresponding hornbeam-oak forests or acidic mixed oak forests. In addition, the species is occasionally found in spruce forests and in the corresponding spruce forests, and occasionally in parks.

The fuzzy pink-blotch likes loose, sandy and only slightly compacted, base-poor and nutrient-poor, fresh to moist, mossy, humic soils. It tolerates sandy soil, silicate sands, brown earth , podsol and also marl and limestone soils if they are sufficiently acidic.

The fruiting bodies usually appear from late July to mid-October. The mushroom prefers the hilly to middle mountainous region. It is also found less often in the flat or higher mountain regions.

  • The fuzzy Täubling is a Holarctic species that can be found almost all over the northern hemisphere. It occurs in North Asia ( Russia-Far East , Japan), North Africa (Morocco) and Europe. The distribution area spans almost three climate zones, and ranges from the meridional zone, with a Mediterranean climate, to the subboreal zone in the north.

    In Germany the Täubling is at least regionally common, in pure limestone areas it is rarer.

    Systematics

    Inquiry systematics

    The fuzzy pink blotch is placed in the Roseinae subsection within the Lilaceae ( Incrustatae ) section. 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. Spore powder whitish or yellow. The taste is mild, but sometimes also bitter.

    Closely related is the very rare small cinnabar drooping ( Russula emeticicolor ) and the also rare small pink drooping ( Russula minutula ).

    Subspecies and varieties

    The following varieties of the fishnet-stalked pink-blubber have been described.

    variety author description
    Russula aurora f. cretacea Zv. Albino form with a pure white hat, mostly under beeches
    Russula aurora f. pulposa Romagn. The lamellas are distant and are soft or "mushy". The hat is up to 9 (11) cm wide, almost like the Aurora type. It is quickly depressed, bright pink and marbled yellow near the center. With smaller spores. This one with many more isolated warts. Under hornbeams.
    Russula aurora var. Heteroderma Romagn. Lamellae normally dense, but cap skin shiny and of the same color as R. emetica to R. velenovskyi . The middle of the hat is almost copper-colored, the edge is sometimes more carmine-red. The hat is up to 5, in exceptional cases 7 cm wide and the stem 6 (7) × 1–1.5 (2) cm. It is relatively firm, white or almost greyish-veined and the tip of the stem is not or only slightly flaky. The flesh is whitish, but can also become almost yellowish. The odor is weak and similar to R. emetica or smells slightly of honey. The spores are 7–8 (8.5) × 5–6.5 µm wide and long, fine-grained with some thorny warts. These are sometimes a little higher than the type. The variety occurs under deciduous trees, often in damp locations.
    • The R. Singer to the subspecies Russula aurora subsp. zvarae (Velen.) Singer downgraded ruby-red deafbling is now again regarded as a separate species under the name Russula zvarae .
