The coal deafening ( Russula anthracina ) is a fungus from the family of the deaf relatives . As is customary for the black pigeon, the old pigeon has a brown-black hat. Its flesh blackens if you cut it without turning red and the lamellas usually have a pinkish tint. That is why it is also called the salmon-leaved black-blotch .

features

Macroscopic features

The hat is 5–10 (–12) cm wide. Young the hat is convex and whitish, but soon the middle deepens and the hat first discolours cream-colored, then blotchy smoky gray and finally black-brown to blackish with age. The hat skin is dry and matt and a quarter peelable. The unrubbed edge remains curved for a long time and is creamy white for a long time and later marbled with brown spots.

The crowded and often forked lamellae are broadly attached to the stem or run down slightly. They are whitish or cream-colored and usually have a pink reflex. When injured, they turn black-brown. The spore powder is white.

The quite short, cylindrical and sometimes tapered stalk is 4–6 (–7) cm long and 1.5–2.5 cm wide and finely wrinkled. It is colored similar to the hat, initially whitish and black-brown with age. It blackens when touched.

The flesh of the hat is quite thick, firm to hard and blackens very quickly in the cut or in the event of an injury without reddening beforehand. The smell is slightly fruity and the taste in the lamellas is sharp to pungent. The meat of the hat reacts salmon-pink with iron sulfate , gray-green with guaiac and purple-brown with phenol.

Microscopic features

The elliptical spores are 6.5–9 µm long and 5.5–7 µm wide. The fine and rather low warts are connected like a network by thin lines.

The coal-deadening differs from other black-deadening birds by its dark brown, vacuolar pigment, which is arranged like a string of pearls in the blunt, 3–6 (-10) µm wide hyphal end cells.

Species delimitation

The black tarnishing blubber ( Russula albonigra ) is very similar , whose lamellae have no pink reflex and whose flesh tastes bitter like menthol.

ecology

The coal pigeon, like all pigeons, is a mycorrhizal fungus that forms a symbiosis with both deciduous and coniferous trees. At least in Germany, spruces are clearly preferred as partners, followed by firs and beeches .

The Kohletäubling can be found in beech and beech coniferous forests on fresh, constantly watered, medium to deep soils. The fungus prefers moderately nutrient-rich, but base-rich and more or less calcareous, sandy-loamy to loamy brown earth soils over lime. Romagnesi specifies wet or boggy mixed deciduous forests in the vicinity of swamp holes as the location for the type and names red beech , field maple and spruce as possible mycorrhizal partners. The fruiting bodies appear between August and October. Colline to montane locations are preferred.

distribution

European countries with evidence of finding of the coal dew.

  • The coal deaf is a meridional to temperate species and occurs in North America (USA), Japan, North Africa (Morocco) and Europe. In Europe, it occurs mainly in southern, western and central Europe, but southern Scandinavia is also part of its distribution area. He was also found in Cameroon.

    In Germany the fungus is very rare north of the 51st parallel, in southwest Germany it is widespread. In the red list, the species is listed in the hazard category RL3.

    Systematics

    Inquirerous classification

    In the sub-genus Compactae, the coal-deafening is a typical representative of the subsection Nigricantinae , a subsection within the section Compactae . In the subsection, deaflings are grouped together whose flesh turns red, gray or black when injured.

    Subspecies and varieties

    There are several varieties of the Kohletäubling, which can be determined with the following key (after Bon).

    1a The lamellas taste mild and have a salmon pink to brick-colored tone. The spores are up to 11 (12) µm long. var. insipida
    1b The lamellae taste hot and are pink, cream-colored or whitish in color. The spores are smaller than 10 µm.
    2
    2a The lamellae are distinctly pink (reminiscent of Clitopilus prunulus) var. carneifolia
    2 B The lamellas are whitish or cream, but not pink.
    3
    3a The hat is blackish and brownish spotted or marbled. The fruiting bodies smell faintly fruity. The ends of cap skin hyphae are more or less thick or short, the limbs measure up to 30 (50) x 6–8 (10) µm. var. anthracina
    3b The hat is whitish and unchangeable, only the flesh tends to blacken. The odor is insignificant and spores measure 9-10 × 8-8.5 µm and are finely ornamented. The cap skin hyphae are slender and 4 (5) µm wide. var. semicrema

    Russula anthracina var. Anthracina Romagn.

    The type always has a distinct and long-lasting sharp taste. The hat changes color from whitish to dark brown-blackish. The slats are white or cream, but never pink. The spores measure 8-10 × 6.5-8 µm. The warts are up to 0.37 µm high and are partially connected like a network. It prefers moist to boggy deciduous and mixed deciduous forests and likes to be found near water.

    Russula anthracina var. Caneifolia Romagn.

    The variety has smaller pores (6.7–8.5 × 5–5.7 µm), but also tastes hot. It occurs in the deciduous forest on silicate rock. Its lamellas are distinctly pink in color.

    Russula anthracina var insipida Romagn.

    This variety is probably more common in Germany than the type. The spore size corresponds to the type, but the warts are clearly more networked and protrude more clearly. They are about 0.5 µm high. There are no laticifers in the stem bark . This Romagnesi found this variant under hazelnut and oak on weakly acidic soil.

    Russula anthracina var. Semicrema Bon

    The hat does not change color, only the flesh of the hat tends to blacken. Hat skin epicutis only weakly differentiated with narrow hyphae 3–5 µm wide. The spores are finely ornamented. The variety occurs under deciduous trees.

    Other related species

    In 1992 Sarnari described a form closely related to var. Insipida as Russula atramentosa . He found it in the Mediterranean maquis over lime. The spores are slightly smaller and the warts are no higher than 0.5 µm.

    Two related species with dubious species rank are also known from North America, which are possibly only varieties of the coal-deaf. Russula sordida Peck and Russula michiganensis Shaffer.

    meaning

    The coal deaf mushroom is not an edible mushroom, young and mild forms such as the insipida variety are probably edible to a limited extent.
