The mutable Täubling ( Russula versatilis ) is a fungus from the family of Täubling relatives . It is a rare, small and fragile blubber with an initially purple, wine-reddish or pink colored hat and ocher-yellow lamellae when ripe. The deafbling has a distinct and pleasant smell of geranium or applesauce and tastes mild.
features
Macroscopic features
The hat 2–4 (-5) cm wide and quite thin and fragile. At first it is flat convex, then expanded and sometimes depressed. The edge is blunt and only slightly grooved. The hat color is more or less pale purple, brownish-wine red or pink in color. However, the hat tends to discolour strongly and is then often olive-brown or grayish in color, either more towards the edge or towards the middle. Often, however, the center turns pink-cream, sometimes almost copper-colored or straw-yellow. The hat skin is greasy, shiny and more or less finely wrinkled.
The lamellas are pretty close to far away. They are bulbous, thin, 3.5–8 mm high and colored whitish-cream to more or less cream-ocher. Often they are cross-veined. The young lamellas have a rather sharp taste. The spore powder is dark cream to pale yellow in color ( IIIc-IVa according to Romagnesi ).
The stem is 3–5 (–6) cm long and 0.5–1 (–1.2) cm wide. It is club-shaped or expanded below the lamellae, fragile, flexible and often hollow with age. At first the steep is colored white; but it tends to yellow and over time becomes rust-stained at the base.
The flesh is thin and white and may yellow a little. It has a distinct, sometimes fleeting smell of geranium or applesauce, which is somewhat reminiscent of the smell of the gall bladder . The taste is mild, the guaiac reaction strongly positive and the iron sulfate reaction inconspicuous.
Microscopic features
The spores are (6.5–) 7–8.5 µm long and 5–6 (–6.5) µm wide and are covered with thorny, fairly isolated, hardly burr-connected warts. The cystides measure 50–85 × 6–13 µm and are otherwise not very conspicuous. The ends are blunt or button-like thickened. The basidia are 27–42 µm long and 9–11 µm wide.
The hyphae end cells of the cap skin are cylindrical, blunt, 2–3 µm wide and fairly clubbed or hardly narrowed at the ends. The cylindrical pileocystidia are 6–8 µm wide, 2–3 (–5) -fold septate and divided into a few almost isodiametric cells.
Species delimitation
The mutable Täubling is a difficult species to identify because it has only a few characteristic features and both the hat color and the spore powder are very variable.
The closely related puddle blubber ( Russula terenopus ) is very similar, but its hat is usually less pale greenish-olive and is a typical aspen companion. Also similar can Russula gracillima fo. be dulcis , a form of the delicate birch blubber . The hornbill usually tastes hotter and has a more or less pink stem.
Ecology and diffusion
The changeable deaf, like all deaf, is a mycorrhizal fungus that can enter into a partnership with various deciduous trees. The rare Täubling can be found in shady, moist deciduous forests under hornbeams and hazelnuts, but probably also under other deciduous trees.
Systematics
Inquiry systematics
The convertible deaf is placed by M. Bon in the sub-section Odoratinae , which is within the section Tenellae . The representatives of the subsection have a distinct, pleasant, often geranium-like odor and a more or less mild taste. The spore powder color is variable, it can be cream, ocher or yellow. The meat is yellow but not gray. Romagnesi places the deaf in its subsection Puellarinae .
meaning
As a mild-tasting Täubling, the Changeable Täubling is theoretically edible, but because of its rarity, its small size and the fragility of the meat, it should hardly be collected.
