The glossy yellow yolk blotch ( Russula acetolens , syn .: Russula lutea , Russula vitellina ) is a fungus from the family of blotch relatives . It is quite a small, fragile blubber with a yellow colored, shiny hat and saffron yellow lamellas. Old specimens typically smell like vinegar. The deaf has a mild taste and is usually found in deciduous forests. Other names for this Täubling are Gelber Hazel Täubling or Gelber Apotheken Täubling .
features
Macroscopic features
The hat is 2–5 cm wide and quite fleshy in relation to its size. It is quickly expanded or depressed, with a flattened center. The edge is slightly bumpy and grooved with age. The hat is yellow, either light lemon yellow (citrine-colored) or, more rarely, egg-yellow or apricot-colored. Older specimens may fade. In contrast to other Chamaeleontines, the hat is never colored red and has no reddish tones either. The almost completely removable hat skin is shiny even in dry conditions, in damp weather it is often a bit greasy.
The widely spaced and quite thick lamellae have grown narrowly on the stem. They are more or less saffron yellow and often have an ocher-orange reflex. The edges of the lamellas are often lighter in color. The spore powder also has an intense yellow color ( IVd according to Romagnesi ).
The slender, delicate stem is 2–3 (–6) cm long and 0.3–1 cm wide. It soon becomes pithy on the inside and is easily compressible. In old age it is mostly hollow and a little wrinkled. It is white, rarely tinged with pink, and sometimes dirty yellow. In old age it can also be slightly grayish.
The white flesh is soft, very fragile and tastes mild. The young mushroom is almost odorless. Only ripe or overgrown specimens clearly smell of vinegar, pickles or mustard. The meat reacts slowly with iron sulfate and turns pale pink in the process. The guaiac reaction is also slow and weak.
Microscopic features
The spores are 7–9 (–9.5) long and 6–7.5 µm wide and have fairly isolated, spiny warts. The cystids are hardly noticeable, they are more or less appendiculated and only react weakly with sulfobenzaldehyde . The hyphae end cells are club-shaped or head-shaped, 4–7 µm wide and articulated. The primordial hyphae are 5–7 µm wide. They are often completely encrusted. The milk tubes can also be stained with sulfo-benzaldehyde.
Species delimitation
The glossy yellow yolk-deafness differs from the alternating -colored or the other yolk-deafness in its vinegar smell, which is unpleasant with age or when it is dry (like cucumbers in vinegar).
It is also reminiscent of the sun blotch , which also smells of vinegar or mustard, but tastes clearly spicy.
Ecology and diffusion
The shiny yellow yolk-deafblings are like all deafblings a mycorrhizal fungus , which can develop a symbiotic partnership especially with different deciduous trees. In rare cases, conifers can also serve as hosts. The Täubling can be found in oak-hornbeam and red beech forests . The Täubling has a preference for more or less moist soils.
The rare Täubling was found in Austria, Germany, Italy, the Czech Republic, Slovakia, Slovenia, Estonia, Spain and Great Britain (including Northern Ireland) and in Ireland.
Systematics
Inquiry systematics
The shiny yellow yolk-blubber is placed by M. Bon in the subsection Chamaeleontinae , a subsection of the section Lilaceae ( Incrustatae ). The subsection contains mild deafblings with yellow spore powder and mostly velvety hat skin. Under the microscope, encrusted primordial hyphae and hyphae end cells with more or less clubbed or capped hyphae can be seen.
meaning
The mild-tasting blubber is classified as edible by the French Society for Mycology. But since the species is quite rare and the fruiting bodies are quite small and very fragile, the deaf mushroom does not play a role as an edible mushroom.
