The green-discolouring blubber ( Russula postiana syn. R. olivascens ), also called yellow-green or olive-green (yolk) blubber , is a fungus from the family of the blubber relatives (Russulaceae). It is characterized by a strong yellow-green hat and ocher-yellow lamellas as well as a smell of must or marjoram , which arises after lying for a long time.

features

Macroscopic features

The hat is lighter or darker olive to distinctly yellow-green in color, sometimes it contains wine-red-purple to blackish areas. It can occasionally be colored concentrically and appear like the red-stemmed leather-deaf ( R. olivacea ). The hat reaches a diameter between three and seven centimeters. It is not very meaty and relatively soft. The surface is greasy, but ultimately dry and silky. Mostly it is bald, but can appear more or less flaky. The edge of the hat is furrowed with age. The hat skin is removable.

The slats are typically deep orange-ocher with age and are reminiscent of gold lacquer. They are broadly bulbous and stand crowded. In addition, they are forked and often very wrinkled and cross-veined. They are narrowed on the stem.

The stem is colored white and usually very silky. The surface is a bit flaky at times. It has a cylindrical shape and is pointed at the base. It reaches a length of two to seven and a thickness between 1 and 1.5 centimeters. It later becomes soft and slack.

The meat is colored white and tastes mild. After a long period of lying there, it smells of must or marjoram. It has a soft, fluffy consistency and is therefore quite light. With phenol , it usually turns more reddish and finally chocolate-black.

Microscopic features

The spores are yellowish in color. They have a rounded to ellipsoidal shape and measure 8–12 × 8–10 micrometers. The surface is isolated prickly, sometimes with strong cylindrical spines or large warts or plates. Usually it is scattered with fine, very dense points. The cystids are spindle-shaped and often pointed. Only a few are present at the lamellar cutting edges; mostly they stick out.

Species delimitation

The green-discolouring deafness can be confused with the yellow-greenish forms of the two-colored deafness ( R. neglecta ). However, this often still has purple tones. It smells of iodoform , but after lying for a long time there is also a smell of must or marjoram.

ecology

The green discoloration can be found in beech and beech-fir, but also in spruce forests at higher elevations. There it colonizes fresh to moderately moist, neutral to alkaline, or also weakly acidic soils over lime , marls and base-rich primary rock .

It is a mycorrhizal fungus that forms a symbiosis with conifers such as spruce and beech . The fruiting bodies are primarily formed between August and early October. Occasionally they appear a month earlier or later. They can often be found on mossy ground.

distribution

European countries with evidence of finding of the green discolouring blubber.
Legend:
  • Countries with found reports
  • Countries without evidence
  • no data
  • non-European countries
  • The green discoloration is common in Europe in the boreal - montane zone. He is in the mountains from France in the west to southern Poland and the Czech Republic in the east. To the south the area extends to Italy and Romania and to the north to the boreal coniferous forests of Fennos Scandinavia . Thus, the species is largely absent in the lower-lying areas such as the Central European Lowlands.

    In Germany the fungus has only been found in the south. The finds come from Baden-Württemberg and Bavaria as well as one each from the southern Palatinate and Saarland.

    Systematics

    Inquiry systematics

    The green discoloration is placed by M. Bon in the subsection Chamaeleontinae , a subsection of the section Lilaceae (Incrustatae). The subsection contains mild deafnesses with yellow spore powder and mostly fine-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 green discoloration is edible.
