features

Macroscopic features

This medium-sized representative of the genus Täublinge has a lemon-yellow to bright chrome-yellow and 4–10 cm wide hat. The surface is greasy and sticky in wet weather, so that leaves or other plant remains are often stuck to it. When it is dry, the hat skin is dull and dull. The middle of the cap of mature fruit bodies is usually slightly depressed, the edge is sometimes grooved or furrowed with age. The hat skin can be peeled off halfway. The 4–10 cm high stem is white, straight and 1–2 cm thick. In young mushrooms, the stalk is full and firm, with age it becomes spongy and gray. The lamellae are pale ocher and bulged on the stem or almost free. All parts of the fungus turn gray to blackish with age or when pressure is applied. The flesh is white and blackened when cut. The smell is barely noticeable to fruity. The spore powder is pale ocher.

Microscopic features

The spores are elliptical, 9–12 µm long and 7.5–10 µm wide, usually 1.5–2 µm longer than wide. The coarse, up to 1 µm high, densely packed, prickly warts are connected by numerous fine lines and form a fairly well-developed network. The basidia are 50–53 µm long and 11 µm wide. The bulbous or clubbed cystids are blunt or pointed above, 55–72 μm long and 7–9 μm wide, with or without a 1 μm long appendiculum . In sulfovanillin, the cystids turn blue except for a pink stalk.

The cap skin contains numerous long, 3–4 µm wide primordial hyphae. Primordial hyphae are hyphae that are more or less strongly encrusted with crystalline or droplet-like secretions, which can be easily stained with carbol fuchsin.

Species delimitation

The also edible lemon deaf can look very similar to the yellow gray deaf, so similar that the yellow gray deaf was for a long time only considered a variety of the lemon deaf. But it is paler, the lamellae are whitish and usually taste sharp.

ecology

The Yellow Gray Stalk Täubling appears from the June to October in high- and intermediate moors , heathland , black alder swamp forests and peat bogs. The fungus prefers moist or alternately moist, acidic and nutrient-poor locations. It is therefore often found near ponds and lakes. It is often found in peat moss pads . Occasionally it also occurs in drier places. The typical mycorrhizal partners are different types of birch . The fungus occasionally enters into symbiosis with alder , ash , quivering aspen and spruce .

    • The yellow gray-stalked blubber is a Holarctic , temperate to boreal species. It occurs in North Asia (Caucasus and Siberia), North America (Canada, USA, Mexico) and Europe. In southern Europe it is mostly absent, in eastern Europe (Belarus) it is rare, in Great Britain, northwest and central Europe it occurs scattered, in northern Europe (Scandinavia, Estonia, northern Russia) it is widespread and extends in Sweden as far as Lapland.

    In Germany, the yellow gray-stalked Täubling occurs irregularly from the coast to the Alps. In northern Germany, it is considered a type of birch quarry. In Germany the species is endangered by the drainage of moors and pollution.
