The yellow-leaved deafblings ( Russula pallidospora ) is a fungus from the family of the deafblings relatives (Russulaceae). It is characterized by a large hat, quite thick leaves that later turn yellow, as well as cream-colored spore powder and small spores (less than 10 µm). Other names for this Täubling are Ocherblättriger Weiß-Täubling or Palesporiger Täubling .

features

Macroscopic features

The thick fleshy hat is between 10 and 22 centimeters wide and is depressed to funnel-shaped. It is initially whitish in color and has a white, fluffy-scabbed coating. Later it gets ocher-colored spots and stripes and loses the coating. In old age, the hat is tinted leathery-yellow with a flesh-colored shade. The brim of the hat is initially rolled up, but later spreads.

The lamellas are initially ivory, then straw yellow and finally Naples yellow. In old age they can also have a light orange, pink or purple hue, but are never greenish. They are relatively thick and quite far apart. The leaves are regularly forked and provided with shorter intermediate lamellae. The edges have fine eyelashes, on which there are often droplets in young specimens.

The white stem is short and thick, the surface smooth and bare. The consistency is coarse and hard. At the base it turns pink-ocher. The flesh is whitish, hard and slightly marbled. The taste is initially mild and then bitter. It smells spicy, but after long storage an unpleasant fish-like odor develops. The meat turns a little flesh pink with iron sulphate .

The spore powder is off-white.

Microscopic features

The spores are broadly ellipsoidal in shape and measure 8-10 × 6.5-8 micrometers. The surface is dotted to fine black and has fine ridges. There are numerous cystids on the edges and surfaces of the lamellae. They protrude far and are very variable in shape.

Species delimitation

The yellow-leaved deaf can be confused with other white deaf (Section Plorantes ) such as the common white deaf ( R. delica ). However, this has no yellowish lamellae, which are further away. In addition, its meat tastes hot after a while. The narrow-leaved blubber ( R. chloroides ) is characterized by denser, bluish lamellae. It also tastes hot. Russula pseudodelica is said to have spores with strong, mostly isolated warts.

ecology

The yellow-leaved Täubling can be found in deciduous forests on limestone and lime sand soils , but acid climbing soil is also specified. The fruiting bodies are formed in August and September.

distribution

European countries with evidence of finding of the yellow-leaved blubber.
Legend:
  • Countries with found reports
  • Countries without evidence
  • no data
  • non-European countries

    • The yellow-leaved blubber can be found in Europe, but rarely anywhere. In Western Europe (France) the occurrences are particularly rare. To the north, the distribution area extends to Denmark.

    In Germany, the fungus is only found in Bavaria, Baden-Württemberg, Saarland and Rhineland-Palatinate. Also from Austria there have been only a few finds in the last 10 years.

    meaning

    The edible value of the yellow-leaved blubber is not known.
