The small pink deafness ( Russula minutula ) is a mushroom from the family of the deaf relatives (Russulaceae). By and large , it is similar to the Greater Pink Täubling ( R. aurora ), but it is slightly larger. The little pink-blubber has a flesh to purple hat that is 1.5 to 4 centimeters wide. The mushroom stands out because of its "beautiful" colors.

features

Macroscopic features

The hat is colored solid pink or flesh red. It often appears like a small cherry-red Spei-Täubling ( R. emetica ) or a reddish yolk-Täubling ( R. lutea ). In the middle it is often tinted pale or pale brown. The surface is a bit greasy and later dry. It is also a little velvety, with a grainy crack at the edge. The hat is quickly spread out and later depressed in the middle and has a small gooseberry or light cream-colored hump. The brim of the hat is thin and grooved somewhat bumpy with age. Half of the skin can be peeled off up to two thirds.

The lamellae are pale, thin, and soft. They are forked, almost distant, are rounded on the stem and stand free. The spore powder is tinted whitish. It turns vivid yellow when dry.

The stem is white, but often tinged with pink. The surface is initially completely frosted. The consistency of the stem is fragile and later also spongy and hollow. The meat tastes mild and has a faint odor. With sulfovanillin , it turns a distinct eosin red color after a while .

Microscopic features

The spores are briefly ellipsoidal and measure 5.7–7.7 x 5–6.7 micrometers. The surface is isolated from fine black to incompletely networked. The cystids are club-shaped and have content bodies.

Species delimitation

The fuzzy pink blotch ( Russula aurora ) is very similar . The most noticeable distinguishing feature is the larger hat diameter of the large pink blubber, which almost always reaches larger dimensions (usually at least 5 cm). In addition, its stem is more conspicuously frosted and less often tinged with pink. Its spores are more ellipsoidal and slightly more fine-black. The Little Pink-Täubling also has a faint odor that is reminiscent of the thick-skinned potato bovist ( Scleroderma citrinum ) or the stink umbrella ( Lepoita cristata ).

ecology

The Kleine Rosa-Täubling can be found in beech and oak-hornbeam forests as well as in parks. There it grows on neutral to slightly acidic, fresh, sandy-loamy to clay soils. These are well supplied with bases, but low in nitrogen and formed over silicates .

The small pink deaf fungus is a mycorrhizal fungus that is in symbiosis with deciduous trees such as oak , red beech and sweet chestnut . The fruiting bodies appear from July to September.

    • The little pink-blotch is common in Europe and the Caucasus . In Europe the area stretches from Spain to Slovenia in the south, from France to the Benelux countries to Great Britain in the west and to Belarus in the east. In the north, the deafling was found in Denmark and Norway.

    Systematics

    Inquiry systematics

    The Little Pink-Täubling is placed by Bon in the Roseinae subsection , which is in 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. The taste is mild, but sometimes also bitter.
